Climate refugia, locations where taxa survive periods of regionally adverse climate, are thought to be critical for maintaining biodiversity through the glacial-interglacial climate changes of the Quaternary. A critical research need is to better integrate and reconcile the three major lines of evidence used to infer the existence of past refugia - fossil… (More)
a r t i c l e i n f o Keywords: genetic diversity glacial refugia hindcasting palaeobiogeography Spain species distribution modelling The forests in the Iberian Peninsula have been strongly influenced by past climatic changes, but reconstructing their historical distributions and dynamics is very difficult due to the complex climatic characteristics and… (More)
The history of Earth is a history of recurrent climate change. Today's global biodiversity demonstrates that many species have been able to cope with climate shifts in the past. Yet great concern exists that modern climate change is likely to overstrain the capacity of many species to track suitable climate spaces, potentially leading to widespread… (More)
By the use of immunocytochemical staining methods, we studied the morphology and distribution of 5HT and NPY immunoreactive cells and fibres in the mouse adrenal gland. The 5HT-immunoreactive cells were numerous and widely localized in the medullar tissue. These cells were arranged in three cellular types with regard to their morphological and… (More)
1. Biogeographic and biodiversity responses to climate change since the Last Glacial Maximum. 2. Paleoecology, paleoclimatology, disturbance ecology, and fire history, with a focus on forests of the Pacific Northwest.
An accurate understanding of the factors that influence farmers’ adoption of a crop is critical for effective policy promotion and technical support. Agroforestry crop adoption is a complex topic involving many factors not often addressed by tradition crop adoption models. This complexity, when applied to Jatropha (Jatropha curcas L.), an often widely… (More)
