A novel nematode species from the Siberian permafrost shares adaptive mechanisms for cryptobiotic survival with C. elegans dauer larva

Authors: Anastasia Shatilovich , et al. Abstract Some organisms in nature have developed the ability to enter a state of suspended metabolism called cryptobiosis when environmental conditions are unfavorable. This state-transition requires execution of a combination of genetic and biochemical pathways that enable the organism to survive for prolonged periods. Recently, nematode individuals have been…

Phylogenetic and biogeographical traits predict unrecognized hosts of zoonotic leishmaniasis

Authors: Caroline K. Glidden , et al. Abstract The spatio-temporal distribution of leishmaniasis, a parasitic vector-borne zoonotic disease, is significantly impacted by land-use change and climate warming in the Americas. However, predicting and containing outbreaks is challenging as the zoonotic Leishmania system is highly complex: leishmaniasis (visceral, cutaneous and muco-cutaneous) in humans is caused by…

Life history optimisation drives latitudinal gradients and responses to global change in marine fishes

Authors: Mariana Álvarez-Noriega , et al. Global patterns in mortality, growth, and offspring size Natural mortality (M) (expressed as a size-independent mortality rate that is not a product of fishing) is highest at the tropics and decreases by 80% closer to the poles (from 0.85 y−1 at 0° to 0.17 y−1 at 60°), which constitutes…
