The Journal of Wildlife Management, EarlyView.Snowshoe hare population densities in Pennsylvania were greatest in early‐successional forest and densely‐understoried mature forest. Forest management that increases and maintains the amount of early‐successional forest, or that increases understory complexity in mature forest, would benefit snowshoe hares and may mitigate population declines under ...

Integrative Zoology, EarlyView.We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

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