Environmental drivers of scale morphology in a Canary Island lizard across 3700 m of elevation
Gallotia galloti scale traits are driven by climate and human pressures. High dorsal density correlates with hotter, dryer environments and larger scales with higher sun exposure, while ventral scale....

Why do we still need standardized journal abbreviations? It looks like something that was important to save space when journals were printed on paper, but are a complete waste of time nowadays.

Funny how, when two academics meet, the first thing they do is perform that “song and dance” ritual to uncover even the slightest overlap in their research interests.
