Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans

open access: yesIntegrative Zoology, EarlyView.
An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.

Seasonal Habitat Selection by a Threatened Ungulate in an Industrializing Boreal Landscape

open access: yesAnimal Conservation, EarlyView.
Understanding habitat selection by Threatened wood bison in landscapes characterized by anthropogenic disturbance is important for conservation planning. During summer and winter, bison selected for linear (e.g., roads, seismic lines, pipelines) and polygonal (e.g., well sites) disturbances, unless there were high densities of linear features.

open access: yesBoreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the
