Plaguicidas, impacto en salud y medio ambiente en sinaloa (méxico): implicaciones y retos en gobernanza ambiental

Trayectorias Humanas Trascontinentales, 2019
El uso de plaguicidas en el sector agrícola sinaloense es una de las prácticas más comunes en la actividad primaria de la región. La exposición a éstos representa un factor definitivo, a la vez para la salud ambiental y la de la sociedad, en este caso la

Harvesting of two alpine Artemisia: Effects of an amateur practice on wild plant dynamics

PLANTS, PEOPLE, PLANET, EarlyView.
Wild plants are consumed all over the world, and knowledge of the effects of harvesting is necessary to ensure the sustainability of this activity. Our 3‐year study of two closely related alpine Artemisia species in the Southern Alps revealed a positive impact of harvesting at the plant scale and on the short term.

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

PLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

Peri‐urban agroforestry for climate mitigation in West Africa: Structural diversity and functional traits as key drivers of carbon storage

PLANTS, PEOPLE, PLANET, EarlyView.
Peri‐urban areas in West Africa are expanding rapidly, often with limited planning and growing exposure to climate risks. Our study shows that agroforestry systems in these landscapes, especially diverse home gardens, can store substantial amounts of carbon when they include structurally complex stands and species with traits that favor biomass ...

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel

River Research and Applications, EarlyView.
ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...

Impact of the Addition of a Shading Algorithm in a Physically Based Conceptual River Hydrological–Temperature Model

River Research and Applications, EarlyView.
ABSTRACT Anthropogenic impacts on the thermal regime of rivers include climate change and deforestation. For the latter, developing modelling tools that can account for the impact of varying vegetation cover on river temperatures is essential. This study describes a new addition to the CEQUEAU hydrological and water temperature model: a shading ...

Global meta‐analysis reveals urban‐associated behavioural differences among wild populations

Journal of Animal Ecology, EarlyView.
Urbanization drives rapid phenotypic change, yet broad patterns of behavioural responses remain unclear. Using a global phylogenetic meta‐analysis, we show urban populations exhibit increased boldness, aggression, exploration and activity—especially in birds—highlighting consistent behavioural shifts and revealing major taxonomic gaps that limit our ...

Faut-il continuer à ignorer les pratiques de la RSE en Afrique subsaharienne?

Revue Marocaine de l'Entrepreneuriat, de l'Innovation et du Management, 2019
Relatant la vie des entreprises africaines, cet article essaie de montrer que les réussites tiennent notamment aux liens qui existent entre les pratiques de la responsabilité sociale des entreprises (RSE) et les valeurs du milieu local.
