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.

Anolis lizards are well known for their colorful, expandable throat fan, called the dewlap, which they use to attract mates and repel rivals. The dewlap is a very thin structure and some of the light that strikes its surface shines through it, becoming colored and spreading in all directions as it does. Researchers Leo J. Fleishman, Brianna Ogas, David Steinberg and Manuel Leal look at why some Anolis lizard dewlaps glow in their video.

Alan Knapp talks to the 2014 Haldane Prizewinner Scott Ferrenberg about his paper, "Smooth bark surfaces can defend trees against insect attack: resurrecting a ‘slippery’ hypothesis". See the winner's Virtual Issue here: http://j.mp/Haldane2014
Ken Thompson talks to Katie Field about her Virtual Issue Mycorrhizal networks in ecosystem structure and functioning. The vast majority of land plants form mutualistic symbioses with soil-dwelling fungi known as mycorrhizas, which can link many plants through fungal hyphae in a common mycelial network. This Virtual Issue highlights three major themes in mycorrhizal research: the movement of plant-fixed carbon, reciprocal exchange of nutrients, and the wider impacts on biodiversity and ecosystem function.
In this study, the authors measured song frequency content and hearing sensitivity for nine species of songbird over a broad range of frequencies. If hearing correlates to song characteristics, then open habitat bird species should have higher sensitivity to high-frequency sounds than forest species. Surprisingly, although song frequency was highest in species from open habitats and lowest in forest species (as expected), song frequency and habitat were not correlated with high-frequency hearing sensitivity.

Survival of the weakest seems an unlikely title for an ecology paper, but that is exactly what Haldane prizewinner Kyle Demes and his co-authors found in their, as Kyle Demes explains in this podcast on his paper, Demes, K. W., Pruitt, J. N., Harley, C. D.G., Carrington, E. (2013), Survival of the weakest: increased frond mechanical strength in a wave-swept kelp inhibits self-pruning and increases whole-plant mortality.
