Differences in characteristics between naturalized threatened plants and other threatened plants
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.

Anticompetitive Vertical Merger Waves [PDF]
, 2013 We develop a model of vertical merger waves leading to input foreclosure. When all upstream firms become vertically integrated, the input price can increase substantially above marginal cost despite Bertrand competition in the input market.

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.Our study highlights that when acclimatisation periods are too short, the substantial economic and logistical investment in soft‐release protocols may fail to deliver the expected conservation gains. Therefore, defining evidence‐based acclimatisation periods that are long enough to promote settlement, yet compatible with logistical constraints, may ...

Biotropica, Volume 58, Issue 2, March 2026.Peruvian frogs underwent a climate‐driven range expansion into deglaciating mountains, exposing themselves and their fungal pathogen Batrachochytrium dendrobatidis (Bd) to challenging new thermal environments. Bd has dispersed extensively in these new habitats, and elevation may mediate the apparent sublethal impacts of infection for frogs.
