Each year the BES awards a prize for the best paper, in each of its journals, by an author at the start of their research career. In this podcast, Alan Knapp talks to Brian Steidinger, winner of the 2015 Haldane Prize for Early Career Research, about his prizewinning paper Variability in potential to exploit different soil organic phosphorus compounds among tropical montane tree species. Read the Virtual issue containing all the winning and highly commended papers here..

How do lizards adjust to life in the city? Lizards may use fences, posts and walls as they do trees in natural forests, but they may not find walls as easy to walk up as trees. Jason Kolbe discusses his recent paper City slickers: poor performance does not deter Anolis lizards from using artificial substrates in human-modified habitats with Duncan Irschick.

Thomas Hasper and Johan Uddling talk to FE Editor Alan Knapp about their recent paper "Water use by Swedish boreal forests in a changing climate.Hasper, T. B., Wallin, G., Lamba, S., Hall, M., Jaramillo, F., Laudon, H., Linder, S., Medhurst, J. L., Räntfors, M., Sigurdsson, B. D. and Uddling, J.

Islands are often considered ideal biological laboratories as they are isolated and vary tremendously in size, structure, and habitats, imposing different selective pressures that can drive adaptations of organisms on islands. This study capitalizes on an island-size gradient in the Greek Archipelago to investigate inter-island divergence in the body size, head shape, and bite force of a lizard, Podarcis erhardii.

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. 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. This dataset is a significant increase in information for tropical tree species and indicates a potential for highly diverse species responses to drought within given forest communities.

The Huia (Heteralocha acutirostris), is an extinct New Zealand bird species with an interesting dimorphism such that the female has a dramatically longer bill than the male. The last individuals may have survived until as recently as the 1960s. Species such as this are often suggested as candidates for de-extinction: they are recently lost species of significant conservation interest, and the threats that caused their extinction are known. This paper discusses how using a decision theory approach to conservation prioritization can help managers decide if de-extinction of such species is a good idea.   – photographer J.L . Kendrick.
