Identifying valid surrogates for amphibians and reptiles in pesticide toxicity assessment
Science for Environment Policy, issue 514, 04 octobre 2018, published by the European Commission’s DG Environment and edited by the Science Communication Unit (SCU), at the “University of the West of England, Bristol. [site visité le 05 octobre 2018]
Environmental pollution is putting amphibians and reptiles at risk, yet these animals are not included in regulations regarding the environmental risk assessment (ERA) of pesticides. The extent to which other species already used in pesticide toxicity assessment (including fish, birds and mammals) can serve as effective surrogates is currently under debate. This study conducts a systematic review of the available literature. […]”

How the African elephant cracked its skin to cool off
University of Geneva, phys.org, 02 octobre 2018 [site visité le 03 octobre 2018]
« An intricate network of minuscule crevices adorns the skin surface of the African bush elephant. By retaining water and mud, these micrometer-wide channels greatly help elephants in regulating their body temperature and protecting their skin against parasites and intense solar radiation. Today, researchers at the University of Geneva (UNIGE), Switzerland, and the Swiss Institute of Bioinformatics (SIB) report in the journal Nature Communications that African elephant skin channels are true fractures of the brittle and desquamation-deficient outermost skin layer.

Giraffe babies inherit spot patterns from their mothers
Pennsylvania State University, phys.org, 02 octobre 2018 [site visité le 03 octobre 2018]
« Some features of a giraffe’s spot pattern are passed on from mother to baby, according to a new study led by researchers from Penn State. The study also reveals that survival of young giraffes is related to spot pattern, which may help provide camouflage from predators. The new study, published October 2 in the journal PeerJ, confirms a 49-year-old hypothesis about the inheritance of giraffe spots and highlights a new toolset that can be used to study the markings of wild animals.

Popular interest in vertebrates does not reflect extinction risk and is associated with bias in conservation investment
Davies T, Cowley A, Bennie J, Leyshon C, Inger R, Carter H, et al., PLoS ONE 13(9), 2018, publié le 26 septembre 2018 [site visité le 01 octobre 2018]
« The interrelationship between public interest in endangered species and the attention they receive from the conservation community is the ‘flywheel’ driving much effort to abate global extinction rates. Yet big international conservation non-governmental organisations have typically focused on the plight of a handful of appealing endangered species, while the public remains largely unaware of the majority. We quantified the existence of bias in popular interest towards species, by analysing global internet search interest in 36,873 vertebrate taxa. […]”
