Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

open access: yesNew Phytologist, Volume 251, Issue 4, Page 2237-2247, August 2026.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Impact of bicarbonate on ionized calcium and cardiac function in albumin‐free Langendorff perfusion in hearts of male rats

open access: yesPhysiological Reports, Volume 14, Issue 15, August 2026.
Abstract The adult Langendorff methodology lacks standardization, with inconsistencies in the pH and calcium concentrations of Krebs–Henseleit (K‐H) solution. The aim of this study was to clarify these inconsistencies. Adult male Wistar rat hearts were subjected to 40 or 80 min of global ischemia followed by reperfusion.

Is There Life After Death? The Role of Standing Dead Phorophytes in Supporting Tropical Epiphyte Diversity

open access: yesBiotropica, Volume 58, Issue 4, July 2026.
ABSTRACT Global increases in tree mortality from climate change and land‐use are altering forest structures, impacting canopy‐dwelling plants like vascular epiphytes, which depend on host trees (phorophytes). When a phorophyte dies standing, it becomes a snag, the local substrate conditions change and microclimatic exposure may increase, particularly ...

Exploring drivers and costs of partial trans‐Saharan migration in juvenile vultures

open access: yesIbis, Volume 168, Issue 3, Page 1085-1099, July 2026.
Partial migration occurs when only a subset of individuals within a population undertakes a migratory journey. The decision to migrate can be influenced by intrinsic traits (e.g. sex or physical condition) as well as by extrinsic factors (e.g. social environment or resource availability).
