The Anatomical Record, EarlyView.Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.

Conversational Topic Shifts and Topic Maintenance in Autistic and Neurotypical Children
Autism Research, EarlyView.ABSTRACT Topic maintenance and topic shifts are crucial components of conversation; however, existing research lacks a clear quantitative operationalization of these topic management skills. Previous studies suggest that autistic children are less likely than their neurotypical peers to maintain and elaborate on the interlocutor's prior topic, and that

Biological Reviews, EarlyView.ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
Biological Reviews, EarlyView.ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...
