Reduced Adult Neurogenesis in Humans Results From a Tradeoff Rather Than Direct Negative Selection

open access: yesBioEssays, EarlyView.
Embryonic radial glia (RG) generate neurons, glial cells, and later adult neural stem cells, which sustain adult neurogenesis (top, left to right). Human‐specific genetic modifications (blue arrow), selected to boost early RG neurogenic activity, may lead to premature RG exhaustion and reduced adult neurogenesis in the human brain (bottom).

Eustatic and tectonic controls on mixed carbonate‐siliciclastic ramp deposits in the South Pyrenean foreland basin: The Eocene Alveolina Limestone

open access: yesThe Depositional Record, EarlyView.
The lower Eocene Alveolina Limestone records the global early Eocene transgression, but is equally affected by tectonic movements of the Montsec active thrust located in its hangingwall. Tectonic movements and the early Eocene transgression facilitated a detrital provenance shift in the southern Pyrenean foreland from a southern provenance in the ...

Integrating climate change, biological invasions, and infectious wildlife diseases

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Climate change is likely to affect infectious diseases that are facilitated by biological invasions, with repercussions for wildlife conservation and zoonotic risks. Current invasion management and policy are underprepared for the future risks associated with such invasion‐related wildlife diseases. By considering evidence from bioclimatology, invasion
