description Publicationkeyboard_double_arrow_right Article 2003Publisher:Brill Authors: Michel E. Hendrickx;Michel E. Hendrickx;[The medium size Pacific lobsterette, Nephropsis occidentalis Faxon, 1893, is known from only a few records in the east Pacific (Gulf of California to Chile). A recent survey of deep-water benthic communities in the S.E. Gulf of California, Mexico, indicates that it is abundant at depths between 1050 and 1310 m and is tolerant to severe hypoxic conditions (0.38 to 1.4 ml O2/l, with six catches in less than 1 ml/l). Maximum individual size (135 mm, total length) and body weight (31.2 g) are relatively low compared to shallow water commercial shrimps fished in the region, but the species represents a potential by-catch fishery of the pandalid shrimps Heterocarpus affinis Faxon, 1893 and Pandalus amplus Bate, 1886. Sex ratio (n = 46) F : M was 0.6 : 1. The carapace/total length relationship was significantly different between sexes, while fresh weight/total length relationship was not (t-test on slope and Y intercepts; 0.95). The largest specimens (135 mm TL) barely reach 30 g (29.9 g for the largest male; 31.6 g for the largest female) of fresh weight (30-35 large size specimens per kg of fresh product). Tail weight with carapace is slightly lower than 9 g of fresh weight for the largest specimens (average of 36.5% of total fresh weight). Tail weight without carapace is in the range of 4.5 to 5.6 g for larger specimens. La langoustine du Pacifique Nephropsis occidentalis Faxon, 1893, une espece de taille moyenne, n'est connue que de quelques localites dans le Pacifique est, entre le golfe de Californie et le Chili. Une etude recente des communautes benthiques dans le S.E. du golfe de Californie, Mexique, indique qu'elle est abondante a des profondeurs allant de 1050 a 1310 m et tolere des conditions severes d'hypoxie (0.38 a 1.4 ml O2/l; moins de 1 ml/l pour six captures). La taille maximum individuelle (135 mm, longueur totale) et le poids maximum (31.2 g) sont plutot bas si ils sont compares aux crevettes commerciales capturees dans les eaux peu profondes de la region, mais cette espece presente un certain potentiel pour la peche car elle fait partie de la faune qui accompagne les especes de crevettes pandalides Heterocarpus affinis Faxon, 1893 et Pandalus amplus Bate, 1886. Le rapport entre les sexes (n = 46) F : M est de 0.6 : 1. La relation entre la longueur totale et celle de la carapace est significativement differente entre les deux sexes, tandis que celle entre le poids frais total et la longueur totale ne l'est pas (test t sur les pentes et sur l'ordonnee a l'origine; 0.95). Le specimen le plus grand (135 mm TL) atteint a peine 30 g (poids frais de 29.9 g pour le plus grand mâle et de 31.6 g pour la plus grande femelle) ce qui represente environ 30-35 grands specimens par kg de produit frais.

Chávez;Juana Lopez-Martinez; Edgar Alcántara-Razo; Sergio Hernández-Vázquez; Ernesto A. Chávez;AbstractA stock of rock shrimp Sicyonia penicillata was assessed in a fishery recently opened at Bahoa Kino, Sonora, Mexico. An age-structured model with stochastic recruitment was developed, which considers growth rate, natural mortality, and fishing mortality by age. Age groups were followed year by year with a stock-recruitment Ricker function where the seasonal recruitment pattern was defined as well. Simulations might be interpreted as showing a stable population with four year cycles, reflecting a density-dependent process. In 1996, fishing intensity had an apparent compensatory effect on the stock, decreasing the amplitude of natural oscillations and maintaining the stock at a biomass level similar to the size observed in a condition of no exploitation. The stock was found currently underexploited. As a result of the seasonal accessibility and the age of first-catch fishing (adult shrimp), the stock might be capable to withstand high fishing pressure without being overexploited. Se evaluo una poblacion de camaron de roca Sicyonia penicillata, de una pesqueroa recientemente abierta en Bahoa Kino, Sonora, Mexico. Se desarrollo un modelo basado en la estructura por edades que considera reclutamiento estocastico, tasa de crecimiento, mortalidad natural y mortalidad por pesca por grupo de edad. Estos grupos de edad fueron determinados ano tras ano mediante la funcion de reclutamiento de Ricker, en los que tambien se definio el patron estacional de reclutamiento. Las simulaciones muestran una poblacion estable con ciclos de cuatro anos, que indican un proceso de densodependencia. En 1996, la intensidad de pesca tuvo un efecto compensatorio sobre la poblacion, reduciendo la amplitud de las oscilaciones naturales y manteniendo al stock en un nivel de biomasa similar al observado en la condicion sin explotacion. Se encontro que el recurso esta subexplotado. Como resultado de la accesibilidad estacional y de que la edad de primera captura corresponde a camaron adulto, el recurso soporta alta presion de pesca sin dar evidencias de sobreexplotacion.

AbstractIn this paper, we present some new properties of the Mitra‐Wan forestry model written as a discrete‐time optimal control problem. For this problem, the set of stationary states is characterized. For the optimal long‐run management, we consider the following optimality criteria: average optimality, good control policies, bias optimality, and overtaking optimality. We establish relationships between these criteria and show that the value of average optimal policies is constant and equals the value in the optimal stationary state.

Saúl Ramírez-Pérez;Null purse seine sets (those in which the catch is zero) are common in every tuna fishery in the world. Current evidence suggests that different environmental factors can influence the occurrence of null sets. In this study, we used a long-term (2003–2015) database from the tuna purse seine fishery in the eastern Pacific Ocean to analyze the temporal and spatial variability of the occurrence of 1º × 1º quadrants where the retained tuna catch was zero (“null cells”). We fitted a logistic generalized additive model to predict the occurrence of null cells as a function of environmental and operational covariates. Results of the modeling process suggested that high probabilities of null cell occurrence exist mainly in 2 environmentally different zones: the entrance to the Gulf of California, Mexico, and off the coast of Central America. The final statistical model suggested that operational variables (number of sets, type of fishing indicator) are more important to null cell occurrence than environmental factors (sea surface temperature, chlorophyll concentration, sea level anomaly, and El Niño events).

Abstract. Snow avalanches are the result of unstable snow masses that detach from steep slopes as consequence of changes in snowpack structure. Nowadays, remote sensing technologies can improve the knowledge of avalanches phenomenon. This work focuses on the use of high point density aerial LiDAR (Light Detection And Ranging) technology as support to avalanche events prevention and risk mitigation, by presenting an operative application at Colle della Maddalena (Italy), along the road SS n. 21, nearby the French state border. The area is often involved in intense avalanche events that adversely impact on traffic and freight transport. For this reason, regional administrations will activate the Avalanche Artificial Detachment Intervention Plan (PIDAV, 2012) in order to prevent and manage the avalanche risk in the study area, also adopting artificial detachment systems. Main aim of the present work was to generate high resolution information related to geomorphological characterization (i.e. digital elevation models, slope and aspect) of avalanche sites derived from LiDAR data processing, that will help involved authorities in the management of the avalanche control plan. Digital elevation models at 0.5 m of spatial resolution were generated together with relative tridimensional models. Secondly, a preliminary investigation about capabilities and limits of LiDAR technology was done in the identification of avalanche sites only relying on geomorphological information directly derived by LiDAR data processing. Results showed that position of avalanche sites were correctly identified while no information could be obtained about the extension of the sliding area and identification of detachment areas.

Although antibiotics are the best known secondary metabolites, there are others with an enormous range of other biological activities. Moreover, the last two decades have been a phase of rapid discovery of new activities and development of major compounds of use in different industrial fields, mainly: pharmaceutical and cosmetics, food, agriculture and farming. Some examples are: anti-inflammatory, hypotensive, antitumor, anticholestrolemic, but also insecticides, plant growth regulators and environmental friendly herbicides and pesticides. These compounds are usually produced by liquid submerged fermentation, but many of these metabolites could be advantageously produced by solid-state fermentation.

Méndez-Argüello;Ileana Vera-Reyes; Edgar Vázquez-Núñez; Ricardo Hugo Lira-Saldivar; B. Méndez-Argüello;The use of nanotechnologies in agricultural systems has been widely promoted. Nanomaterials have been proposed as a useful tool for the improvement of agricultural practices. Some plants have shown diverse effects in terms of morphological and physiological changes, with uptake and translocation into different parts. A relation has been demonstrated between the dose and the plant response in different crops, with variations from plant to plant. However, the use of nanoparticles for crop production still faces some challenges because of possible toxicity and hazardous effects, and especially because of the lack of experimental evidence that nanomaterials are harmless to plants and humans. Some studies have reported both positive and negative effects of nanoparticles on plant growth and development, depending on the nature of the nanomaterials, application, time of exposure, plant species, and soil characteristics. The objective of this chapter is to describe the effects of the application of nanoparticles on plant development, focusing on the physiological and biochemical mechanisms of plants in relation to nanoparticles. It also reviews the behavior of nanoparticles in the soil and water matrix and their effects on microbial communities interacting with plants.

Dos de ellas son restos de poblaciones silvestres del zapote prieto en el estado de Michoacán. Una está representada por un solo individuo ubicado en el traspatio de una propiedad en Santa María de Guido. La otra está conformada por cinco árboles en una parcela agrícola de Santiago Undameo. Ambas localidades pertenecen al municipio de Morelia.

Little is known about the bias in these estimates relative to typical stove use by residents in rural communities. To assess this bias, the reductions in emissions as a result of installation of an improved wood-burning “Patsari” stove were quantified in both simulated kitchens and field conditions in eight homes with open fire stoves and 13 homes with Patsari stoves in Purepecha communities of Michoacan, Mexico. The results demonstrate that nominal combustion efficiencies (NCEs) of open fire cookstoves were significantly lower (p<0.001) in rural homes during daily cooking activities (89.7±2.0%) compared to WBTs in simulated kitchens (94.2±0.5%), which results in almost a doubling of the products on incomplete combustion (PICs) emitted. Since emissions from the rural residential sector are important in the modeling of atmospheric trace greenhouse gas concentrations in areas that rely on solid fuel use for primary energy provision, if these open fires reflect conditions in other areas of the world, substantial underestimation of emissions from open fires may be present in current emission databases. Conversely, NCEs for the improved Patsari stoves were significantly higher (p<0.01) in rural homes during daily cooking activities (92.3±1.3%) compared to during WBTs in simulated kitchens (87.2±4.3%), as WBTs do not reflect cooking activities in rural homes. Thus the Patsari emits 25% less PICs per kg fuelwood used than the open fire, and carbon emission reductions of Patsari and similar improved stoves are also likely underestimated. Finally, in addition to a reduction in overall particulate emissions for rural homes during daily activities, the ratio of organic carbon (OC) to elemental carbon (EC) within the aerosol fraction decreased between the open fire and improved Patsari stoves. While the overall EC contribution for the brick Patsari was reduced, the fraction of EC increased relative to OC, which makes the overall warming implication more ambiguous given current uncertainties in warming and cooling potentials of these fractions.

Chávez;Juana Lopez-Martinez; Edgar Alcántara-Razo; Sergio Hernández-Vázquez; Ernesto A. Chávez;AbstractA stock of rock shrimp Sicyonia penicillata was assessed in a fishery recently opened at Bahoa Kino, Sonora, Mexico. An age-structured model with stochastic recruitment was developed, which considers growth rate, natural mortality, and fishing mortality by age. Age groups were followed year by year with a stock-recruitment Ricker function where the seasonal recruitment pattern was defined as well. Simulations might be interpreted as showing a stable population with four year cycles, reflecting a density-dependent process. In 1996, fishing intensity had an apparent compensatory effect on the stock, decreasing the amplitude of natural oscillations and maintaining the stock at a biomass level similar to the size observed in a condition of no exploitation. The stock was found currently underexploited. As a result of the seasonal accessibility and the age of first-catch fishing (adult shrimp), the stock might be capable to withstand high fishing pressure without being overexploited. Se evaluo una poblacion de camaron de roca Sicyonia penicillata, de una pesqueroa recientemente abierta en Bahoa Kino, Sonora, Mexico. Se desarrollo un modelo basado en la estructura por edades que considera reclutamiento estocastico, tasa de crecimiento, mortalidad natural y mortalidad por pesca por grupo de edad. Estos grupos de edad fueron determinados ano tras ano mediante la funcion de reclutamiento de Ricker, en los que tambien se definio el patron estacional de reclutamiento. Las simulaciones muestran una poblacion estable con ciclos de cuatro anos, que indican un proceso de densodependencia. En 1996, la intensidad de pesca tuvo un efecto compensatorio sobre la poblacion, reduciendo la amplitud de las oscilaciones naturales y manteniendo al stock en un nivel de biomasa similar al observado en la condicion sin explotacion. Se encontro que el recurso esta subexplotado. Como resultado de la accesibilidad estacional y de que la edad de primera captura corresponde a camaron adulto, el recurso soporta alta presion de pesca sin dar evidencias de sobreexplotacion.

AbstractIn this paper, we present some new properties of the Mitra‐Wan forestry model written as a discrete‐time optimal control problem. For this problem, the set of stationary states is characterized. For the optimal long‐run management, we consider the following optimality criteria: average optimality, good control policies, bias optimality, and overtaking optimality. We establish relationships between these criteria and show that the value of average optimal policies is constant and equals the value in the optimal stationary state.

Saúl Ramírez-Pérez;Null purse seine sets (those in which the catch is zero) are common in every tuna fishery in the world. Current evidence suggests that different environmental factors can influence the occurrence of null sets. In this study, we used a long-term (2003–2015) database from the tuna purse seine fishery in the eastern Pacific Ocean to analyze the temporal and spatial variability of the occurrence of 1º × 1º quadrants where the retained tuna catch was zero (“null cells”). We fitted a logistic generalized additive model to predict the occurrence of null cells as a function of environmental and operational covariates. Results of the modeling process suggested that high probabilities of null cell occurrence exist mainly in 2 environmentally different zones: the entrance to the Gulf of California, Mexico, and off the coast of Central America. The final statistical model suggested that operational variables (number of sets, type of fishing indicator) are more important to null cell occurrence than environmental factors (sea surface temperature, chlorophyll concentration, sea level anomaly, and El Niño events).

Abstract. Snow avalanches are the result of unstable snow masses that detach from steep slopes as consequence of changes in snowpack structure. Nowadays, remote sensing technologies can improve the knowledge of avalanches phenomenon. This work focuses on the use of high point density aerial LiDAR (Light Detection And Ranging) technology as support to avalanche events prevention and risk mitigation, by presenting an operative application at Colle della Maddalena (Italy), along the road SS n. 21, nearby the French state border. The area is often involved in intense avalanche events that adversely impact on traffic and freight transport. For this reason, regional administrations will activate the Avalanche Artificial Detachment Intervention Plan (PIDAV, 2012) in order to prevent and manage the avalanche risk in the study area, also adopting artificial detachment systems. Main aim of the present work was to generate high resolution information related to geomorphological characterization (i.e. digital elevation models, slope and aspect) of avalanche sites derived from LiDAR data processing, that will help involved authorities in the management of the avalanche control plan. Digital elevation models at 0.5 m of spatial resolution were generated together with relative tridimensional models. Secondly, a preliminary investigation about capabilities and limits of LiDAR technology was done in the identification of avalanche sites only relying on geomorphological information directly derived by LiDAR data processing. Results showed that position of avalanche sites were correctly identified while no information could be obtained about the extension of the sliding area and identification of detachment areas.

Although antibiotics are the best known secondary metabolites, there are others with an enormous range of other biological activities. Moreover, the last two decades have been a phase of rapid discovery of new activities and development of major compounds of use in different industrial fields, mainly: pharmaceutical and cosmetics, food, agriculture and farming. Some examples are: anti-inflammatory, hypotensive, antitumor, anticholestrolemic, but also insecticides, plant growth regulators and environmental friendly herbicides and pesticides. These compounds are usually produced by liquid submerged fermentation, but many of these metabolites could be advantageously produced by solid-state fermentation.

Méndez-Argüello;Ileana Vera-Reyes; Edgar Vázquez-Núñez; Ricardo Hugo Lira-Saldivar; B. Méndez-Argüello;The use of nanotechnologies in agricultural systems has been widely promoted. Nanomaterials have been proposed as a useful tool for the improvement of agricultural practices. Some plants have shown diverse effects in terms of morphological and physiological changes, with uptake and translocation into different parts. A relation has been demonstrated between the dose and the plant response in different crops, with variations from plant to plant. However, the use of nanoparticles for crop production still faces some challenges because of possible toxicity and hazardous effects, and especially because of the lack of experimental evidence that nanomaterials are harmless to plants and humans. Some studies have reported both positive and negative effects of nanoparticles on plant growth and development, depending on the nature of the nanomaterials, application, time of exposure, plant species, and soil characteristics. The objective of this chapter is to describe the effects of the application of nanoparticles on plant development, focusing on the physiological and biochemical mechanisms of plants in relation to nanoparticles. It also reviews the behavior of nanoparticles in the soil and water matrix and their effects on microbial communities interacting with plants.

Authors: Ignacio Torres; Santiago Arizaga;Ignacio Torres; Santiago Arizaga;Se documentan tres nuevas localidades del zapote prieto o aguacatillo (Diospyros xolocotzii Madrigal & Rzedowski), una especie críticamente amenazada, así como su estructura poblacional y su hábitat. Dos de ellas son restos de poblaciones silvestres del zapote prieto en el estado de Michoacán. Una está representada por un solo individuo ubicado en el traspatio de una propiedad en Santa María de Guido. La otra está conformada por cinco árboles en una parcela agrícola de Santiago Undameo. Ambas localidades pertenecen al municipio de Morelia. Por el contrario, la tercera corresponde a la población silvestre más conservada hasta ahora conocida en el país de D. xolocotzii, la cual cuenta con alrededor de 1500 individuos. Se ubica hacia el norte de la cuenca del lago de Cuitzeo, dentro de una barranca en la localidad de San José de Las Pilas, municipio de Acámbaro, Guanajuato.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2008Publisher:Elsevier BV Authors: Michael Johnson; Rufus Edwards; Claudio Alatorre Frenk; Omar Masera;Michael Johnson; Rufus Edwards; Claudio Alatorre Frenk; Omar Masera;The majority of estimates of the greenhouse gas emissions associated with changes from traditional to improved cookstoves in developing countries come from water-boiling tests (WBTs) conducted in simulated kitchens. Little is known about the bias in these estimates relative to typical stove use by residents in rural communities. To assess this bias, the reductions in emissions as a result of installation of an improved wood-burning “Patsari” stove were quantified in both simulated kitchens and field conditions in eight homes with open fire stoves and 13 homes with Patsari stoves in Purepecha communities of Michoacan, Mexico. The results demonstrate that nominal combustion efficiencies (NCEs) of open fire cookstoves were significantly lower (p<0.001) in rural homes during daily cooking activities (89.7±2.0%) compared to WBTs in simulated kitchens (94.2±0.5%), which results in almost a doubling of the products on incomplete combustion (PICs) emitted. Since emissions from the rural residential sector are important in the modeling of atmospheric trace greenhouse gas concentrations in areas that rely on solid fuel use for primary energy provision, if these open fires reflect conditions in other areas of the world, substantial underestimation of emissions from open fires may be present in current emission databases. Conversely, NCEs for the improved Patsari stoves were significantly higher (p<0.01) in rural homes during daily cooking activities (92.3±1.3%) compared to during WBTs in simulated kitchens (87.2±4.3%), as WBTs do not reflect cooking activities in rural homes. Thus the Patsari emits 25% less PICs per kg fuelwood used than the open fire, and carbon emission reductions of Patsari and similar improved stoves are also likely underestimated. Finally, in addition to a reduction in overall particulate emissions for rural homes during daily activities, the ratio of organic carbon (OC) to elemental carbon (EC) within the aerosol fraction decreased between the open fire and improved Patsari stoves. While the overall EC contribution for the brick Patsari was reduced, the fraction of EC increased relative to OC, which makes the overall warming implication more ambiguous given current uncertainties in warming and cooling potentials of these fractions.
