Dendrochronology's "Divergence Problem" Explained?

A new study by Alexander Stine and Peter Huybers offers strong evidence that reduced light availability (“global dimming”) explains the apparent lack of tree-ring evidence in many Arctic regions for the recent warming observed in instrumental records there. Dendroclimatology uses measurements of the yearly growth width and density of tree rings to reconstruct changes in past climate. The …

Belowground biotic interactions and how they respond to, and influence climate change via climate-ecosystem carbon feedbacks.

My research interests include soil, ecosystem and climate change ecology. Specifically, my work focuses on biotic interactions and how they respond to, and influence climate change via climate-ecosystem carbon feedbacks. My PhD work, conducted at Cardiff University, centered on the topic of soil biodiversity. This work advanced our theoretical and mechanistic understanding of how top-down processes control soil biodiversity and nutrient cycling.

For Ecologists, Is Climate Change Research Sufficiently Complex?

Climate change will alter myriad natural processes as precipitation patterns shift and oceanic and atmospheric temperatures and CO2 concentrations rise. Modern ecology and environmental science has already examined the potential effects of climate change on species and ecosystems, allowing us to elucidate the mechanisms and pathways through which it may operate (Tylianakis et al. 2008)…

Climate Change Impacts Antarctica's Ross Sea

The Ross Sea, Antarctica’s most pristine region, is experiencing anomalously marked increase in sea ice concentration. Future changes in atmospheric temperatures and wind speeds, however, will likely produce a noticeably different environment. Smith et al. examines the effect of projected changes in atmospheric temperatures and winds on aspects of ocean circulation and its implications for primary…

Ecology and Evolution of Invasive Mosquito Disease Vectors

This presentation will describe interspecific interactions and trait evolution associated with encounters in nature between Aedes aegypti and Aedes albopictus, the most important vectors of dengue and chikungunya viruses. Effects of larval competition on dengue transmission in nature will also be discussed.

Mosquito biology, especially ecology and behavior, is the focus of Phil Lounibos’s laboratory located in Vero Beach, Florida.
