Abstract Background Prioritising equine welfare, making evidenced‐based policy, and consistent decision‐making across sports are crucial to maintaining the social licence for equestrian sport. Regulations on the use of omeprazole during competition differ; all regulators argue that their rules prioritise welfare. This discrepancy is a matter of concern

Small understory trees increase growth following sustained drought in the Amazon. [PDF]

open access: yesNew Phytol
Summary Droughts pose a major threat to the Amazon rainforest, yet the mechanisms enabling trees to maintain growth under prolonged drought remain poorly understood, particularly in the understory layer. We leveraged a 22‐yr Throughfall Exclusion (TFE) in a 1‐ha plot in eastern Amazonia, paired with a Control plot, to test whether small understory ...

Complex and Dynamic Effects of an Extreme Low Temperature Weather Event on Invasive Plant Populations and Resident Communities. [PDF]

open access: yesGlob Chang Biol
Invasive plant species might benefit more from climate change, though evidence for that is not clear. Here, we show that the effects of a low‐temperature extreme weather event can result in a dramatic reduction in both vegetative and reproductive growth of invasive populations of Gunnera tinctoria (giant rhubarb) in the west of Ireland.

Spatiotemporal trends in floral visitation and interaction networks reveal shifting niches for bats in a Neotropical savanna

open access: yesJournal of Animal Ecology, Volume 92, Issue 7, Page 1442-1455, July 2023., 2023
The article reveals that the temporal and spatial axes are important drivers of the floral‐visitor niche of anthophilous bats in a Neotropical savanna, defining the structure of their interaction networks with plants. These findings may aid in the management of the endangered Cerrado bat Lonchophylla dekeyseri. Abstract Flower‐vising bats are important

Why forest fails to recover after repeated wildfires in Amazonian floodplains? Experimental evidence on tree recruitment limitation

open access: yesJournal of Ecology, Volume 109, Issue 10, Page 3473-3486, October 2021., 2021
Our experimental evidence suggests that soil nutrient limitations may slow down forest recovery after repeated wildfires in Amazonian floodplains. Yet, because floodplain trees are able to germinate from seeds and establish successfully in twice burnt forests, seed limitation seems to be the reason why forest recovery fails persistently. Seeding native
