Advancing conservation breeding programs for marine invertebrates

Conservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

A global assessment of animal community responses to agricultural management

Conservation Biology, EarlyView.
Abstract Transitions in agricultural management through crop and noncrop diversification on intensively managed croplands or pastures have benefited biodiversity. However, the extent to which agricultural management benefits species communities present in undisturbed ecosystems remains largely unclear.

Wood Thrush (Hylocichla mustelina) occupancy patterns reveal sensitivity to low precipitation on nonbreeding grounds in northern Costa Rica

Ibis, EarlyView.
Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

L’efficience nette de conversion des aliments par les animaux d’élevage : une nouvelle approche pour évaluer la contribution de l’élevage à l’alimentation humaine

INRAE Productions Animales, 2019
L’élevage est souvent perçu comme inefficient pour produire des denrées alimentaires pour l’Homme car les animaux consomment davantage de végétaux qu’ils ne produisent de viande, de lait ou d’œufs.

Altered photoperiod affects behaviour in a key fish grazer, the thinlip grey mullet, Chelon ramada

Journal of Fish Biology, EarlyView.
Abstract The aim of this study is to address experimentally the immediate impacts of an alteration of the photoperiod, simulating an extreme artificial light pollution, on the behaviour and stress of a key grazer fish common in temperate coastal ecosystems in Europe, the thinlip grey mullet, Chelon ramada.

Entraves au développement de la filière porcine en Casamance (Sénégal) : que disent les acteurs du sous-secteur ?

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2018
Au Sénégal, l’élevage de porc connaît une croissance annuelle de 3,5 % et couvre 15 % de la production nationale de viande blanche. Longtemps négligé par les pouvoirs publics, il suscite désormais un intérêt de la part des politiques de développement ...

Contrasting population genetic structures of freshwater eels (Anguilla marmorata, A. bicolor, A. mossambica) from Madagascar

Journal of Fish Biology, EarlyView.
Abstract Freshwater eels (genus Anguilla) are of major biological and commercial interest due to their complex catadromous life cycle and as a high‐value fishery resource, but the biology of tropical species is still poorly understood. This study investigates the genetic integrity, diversity and population structure of three species of tropical eels ...

Peridomestic infestation by Triatoma pallidipennis and natural infection with Trypanosoma cruzi in Zacatepec, Morelos, Mexico Infestación peridoméstica por Triatoma pallidipennis e infección natural por Trypanosoma cruzi en Zacatepec, Morelos, México

Medical and Veterinary Entomology, EarlyView.
Entomological and community‐related risk factors for Chagas disease were assessed through peridomestic sampling, calculation of entomological indices and surveys of community knowledge, attitudes and practices. Forty‐six triatomines, all identified as Triatoma pallidipennis, were collected, and all specimens showed natural infection with Trypanosoma ...
