Rebecca Senior publishes in Global Change Biology

PhD student Rebecca Senior has just published her research about thermal buffering in selectively logged forests in Global Change Biology.

Themal-image2Selectively logged tropical forests harbour much of the world’s terrestrial biodiversity; their ability to do so in the long term will depend in part on the extent to which temperature-sensitive species can respond to climate change in situ. Using thermal images and temperature dataloggers, Rebecca found that—despite major differences in forest structure—thermal buffering potential in intensively logged forest on Borneo was comparable to that of undisturbed primary forest. Selectively logged forests can therefore play a crucial role in the long-term maintenance of global biodiversity.

Rebecca gave a short interview on BBC Radio Sheffield about this work and what it means for biodiversity (although they got her name wrong!).

Edwards Lab does Science Outreach!

The Edwards Lab got involved with some Science Outreach last week! We took part in the annual Discovery Night event (10th March) at The University of Sheffield as part of the Sheffield Festival of Science and Engineering (https://www.sheffield.ac.uk/discoverynight). We organised a tropical forest exhibit that included activities for the whole family to learn about the unique features of the tropical rainforest, the extraordinary creatures that live there and the current threats to these beautiful forests. The Nadeau lab joined us and brought live tropical butterflies to the exhibit too! We got to share our current research on tropical forests and provide tips on what the public can do at home to help save these important habitats. The event was packed full of families interested in what scientists have been up to and thoroughly enjoyed the event. Our first outreach event as a lab was a success and all round a great experience!

Felix Lim publishes in Conservation Letters

PhD student Felix Lim has published his work on perverse market consequences of conservation actions in Conservation Letters.

The unintended consequences brought about by market feedback effects are often overlooked, yet perverse market outcomes could result in reduced or even reversed net impacts of conservation efforts. Felix and coauthors develop an economic framework to describe how the intended impacts of conservation interventions could be compromised due to unanticipated reactions to regulations in the market: policies aimed at restricting supply could potentially result in leakage effects through external or unregulated markets. Felix reviews how various intervention methods could result in negative feedback impacts on biodiversity, including legal restrictions like protected areas, market-based approaches, and agricultural intensification, and offers suggestions of how to design conservation actions to ensure the risks of perverse market outcomes are detected, if not overcome.

Masters student, Ed Bashman, publishes in Animal Conservation!

EWB0312 (13)Former masters student Ed Bashman (email) has published his research in Animal Conservation, congratulations! Here is a short summary written  by Pam (co-author):

“Amphibian abundance, species richness and threatened species were assessed in cattle pasture, secondary forests (recovering forests) and primary forests in the Tropical Andes. Cattle pasture had the lowest values across all habitats. As secondary forests matured, they recovered to values typically found in primary forests. Also, a positive relationship between carbon stocks and amphibian species richness and abundance suggests that carbon-based funding initiatives can support the regrowth of forests and is likely to conserve threatened biodiversity in the Tropical Andes.” Photo credit: Ed Bashman

Farmlands and bird phylogenetic diversity

How to best protect avian phylogenetic diversity when converting natural habitats to farmland? By integrating wildlife friendly habitats within farmlands or by intensifying farming in some areas to allow tTrogon personatushe offset of natural reserves?

Edwards et al. (2015) study the effects of these two strategies (land-sharing vs land-sparing) and conclude that small-scale integration of wildlife friendly patches may not be enough for many bird species to persist without the protection of larger natural areas. Thus, a land-sparing strategy is more likely to retain evolutionary distinct bird species while establishing highly productive farmland areas.

For a nice summary of the study check GrrlScientist’s article in The Guardian and some great bird pictures here.

Lewis, Edwards and Galbraith in Science

DSC_0544“Increasing human dominance of tropical forests” co-authored by Dr Edwards has just been published in Science. Four chronological phases of human influences on tropical forests are discussed: phase I, hunting and megafauna extinctions; phase II, low-intensity shifting cultivation; and phase III, global integration in which economics drives land-use and climate change.

Finally, the very dreaded phase IV may take place in the near future, so-called “global simplification” by which intensive logging and rapid climatic changes would cause worldwide loss of species. The future lies in the hands of humankind…

Field season in the Amazon begins

Ileana is now set in Rondonia at the Jamari Concession starting our project in collaboration with the sustainable logging company AMATA Brasil. AMATA has “bar-coded” over 100.000 trees with information on their biomass, species and exact location. This enables them to plan selective logging in detail and provides us with a lot of valuable data to carry out research.birdeater

Ileana and Dave have set up sampling plots which we will use for different purposes. Ileana is working on carbon retention and I (Gabriela) will soon be looking at butterfly communities in the area.

Among other creatures, this remarkably large tarantula (goliath birdeater, we think) was photographed by Dr Edwards. Happy days!
