Long‐term jaguar demography underscores the ecological value of Amazonian floodplains
Our results provide the first estimates of recruitment and apparent survival for Amazonian jaguars, key parameters for guiding conservation. We show that seasonal wetlands—the Amazonian floodplain forest and reported estimates from Pantanal and the Llanos—harbour the highest jaguar densities across the species' range.

Generalist passerine birds perform a functional role as pollinators in temperate Europe
Nectar‐feeding birds are effective pollinators. In temperate Europe, songbirds visit flowers but lack specialist traits, so functional pollination has been discounted. We use observations, pollen identification and experiments to demonstrate that generalist birds affect fruit‐set of flowering trees.

Rapid thaw of the Earth's cryosphere in response to anthropogenic warming highlights the need to identify and understand the contrasting signatures of past ice‐sheet stability and collapse. The Kvarken archipelago, western Finland, at the centre of the former Fennoscandian Ice Sheet (FIS), has been designated a UNESCO World Heritage site in recognition

We assessed Spodoptera litura (Lepidoptera: Noctuidae) performance on five common pasture plant species. Larvae consumed more dock, plantain and chicory per day than red or white clover, but with lower conversion efficiencies. Feeding on red clover reduced weights and egg laying, and lengthened development times compared with plantain.

ABSTRACT Growth of ectotherms typically positively correlates with increasing temperature towards an optimal temperature range, followed by a decline in growth when temperatures exceed the optimal temperature range for that organism. When temperature is within or close to the optimal range, food availability and other environmental factors can play ...

Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...
