FE Alan Knapp talks to Isabelle Marechaux on predicting drought tolerance for Amazonian forest trees

Droughts are predicted to become increasingly frequent and intense in Amazonia, and empirical evidence for the vulnerability of Amazonian trees to drought has grown over the past decade. Little is known, however, about the mechanisms or the diversity of drought tolerance in tropical trees and, it has been difficult to quantify drought tolerance in tropical trees, due to a lack of consensus on a relevant tree functional trait, practical to measure for the hundreds of tree species occurring in tropical forests. In this study, Isabelle Marechaux and her co-authors looked at leaf water potential at wilting or turgor loss point (πtlp), which determines tolerance of leaves to drought stress. By using a new method based on a demonstrated association between πtlp and another trait, the leaf osmotic water potential at full hydration, they were able to estimate πtlp for 165 trees of 71 species, at three sites within forests in French Guiana. This dataset represents a significant increase in information for tropical tree species, revealing a wider range of drought tolerance than previously found in the literature and indicating a potential for highly diverse species responses to drought within forest communities. Given the weak correlations between πtlp and traditionally measured plant functional traits, vegetation models seeking to predict forest response to drought should integrate improved quantification of comparative drought tolerance among tree species.

Functional Ecology | Fernando Gonçalves: Pollen essential amino acids shape bat–flower interaction networks

Functional Ecology | Fernando Gonçalves: Pollen essential amino acids shape bat–flower interaction networks

In this podcast, Functional Ecology author Fernando Gonçalves talks to Assistant Editor Amelia Macho about his article "Pollen essential amino acids shape bat–flower interaction networks". Fernando's article discusses how pollen protein and amino acid composition influence year-round and seasonal bat–flower interaction networks. Its results underscore the essential role of pollen, not just nectar, as a key reward for attracting flower-visiting bats, and therefore highlights pollen content as an important driver structuring pollination networks. Read the full article here: https://doi.org/10.1111/1365-2435.70161 Check out a video of the bat species in this study! https://youtu.be/7FX2x4T45i8?si=be7V7t3gAwBR4yiw

ELM Network | Episode 4: Leading with clarity and kindness with Professor Sallie Bailey

ELM Network | Episode 4: Leading with clarity and kindness with Professor Sallie Bailey

As part of our 'Community' series, we’re launching the Emerging Leadership Management (ELM) Network, hosted by Rob Brooker, Thorunn Helgason, and Pen Holland.This is the podcast for people who love to lead or one day might emerge as a leader. This episode features Professor Sallie Bailey, Chief Scientist at Natural England and inaugural BES Fellow. Sallie shares insights from her leadership journey, from shaping strategy and managing expectations to driving cultural change across organisations. We discuss what makes communication effective, how leaders can bring clarity and energy to their teams, and why strong leadership is vital for lasting impact.

Spiders Spotted Using Trapped Fireflies to Lure Prey | The Story Behind The Paper

Spiders Spotted Using Trapped Fireflies to Lure Prey | The Story Behind The Paper

For the Journal of Animal Ecology's latest podcast episode, Associate Blog Editor Edie Abrahams speaks with Professor I-Min Tso about his recently published paper, "Prey bioluminescence-mediated visual luring in a sit and wait predator". Professor Tso reflects on his journey into the world of spiders and what he learnt from conducting his study, as well as providing some valuable insights for those who are interested in pursuing a career in the area.

Included in Nature with Clare Rishbeth | Introduction

Included in Nature with Clare Rishbeth | Introduction

This series will be discussing four evidence reports commissioned by Natural England which were deposited on Applied Ecology Resources and explored the importance of nature inclusion across various communities; people with disabilities, older people, ethnic minorities, and those in low-income areas. This series will be deep diving into the importance of nature connection, the potential barriers to inclusion for four specific groups of individuals, and strategies to overcome them. Our guest is Clare Rishbeth, who is a professor in Landscape Architecture from the University of Sheffield and co-authored the reports. Clare explains the reason for the reports and for the focus on four specific groups of people. The reports are linked below: People with Disabilities https://www.britishecologicalsociety.org/applied-ecology-resources/document/20220436861/ Low Income Areas https://www.britishecologicalsociety.org/applied-ecology-resources/document/20220436862/ Older People https://www.britishecologicalsociety.org/applied-ecology-resources/document/20220436863/ Ethnic Minorities https://www.britishecologicalsociety.org/applied-ecology-resources/document/20220436860/
