Biodiversity Of Medicinal Plants In The Highlands: Problems And Perspectives, Vyacheslav Dushenkov
Biodiversity Of Medicinal Plants In The Highlands: Problems And Perspectives, Vyacheslav Dushenkov
Publications and Research
Climate change is affecting medicinal plants around the world and could ultimately lead to losses of some key species, in particular species endemic to a region and causing plants to migrate to new ranges. As the situation unfolds, climate change may become a pressing issue for the herbal community, affecting medicinal plant supply chains with varying requirements for plant cultivation, resource management in the wild, harvesting, processing, and importantly marketing.
Climate And Changing Winter Distribution Of Alcids In The Northwest Atlantic, Richard R. Veit, Lisa L. Manne
Climate And Changing Winter Distribution Of Alcids In The Northwest Atlantic, Richard R. Veit, Lisa L. Manne

Population level impacts upon seabirds from changing climate are increasingly evident, and include effects on phenology, migration, dispersal, annual survivorship, and reproduction. Most population data on seabirds derive from nesting colonies; documented climate impacts on winter ecology are scarce. We studied interannual variability in winter abundance of six species of alcids (Charadriiformes, Alcidae) from a 58-year time series of data collected in Massachusetts 1954–2011. We used counts of birds taken during fall and winter from coastal vantage points. Counts were made by amateur birders, but coverage was consistent in timing and location. We found significant association between winter abundance of …
What To Eat Now? Shifts In Polar Bear Diet During The Ice-Free Season In Western Hudson Bay, Linda J. Gormezano, Robert F. Rockwell
What To Eat Now? Shifts In Polar Bear Diet During The Ice-Free Season In Western Hudson Bay, Linda J. Gormezano, Robert F. Rockwell

Under current climate trends, spring ice breakup in Hudson Bay is advancing rapidly, leaving polar bears (Ursus maritimus) less time to hunt seals during the spring when they accumulate the majority of their annual fat reserves. For this reason, foods that polar bears consume during the ice-free season may become increasingly important in alleviating nutritional stress from lost seal hunting opportunities. Defining how the terrestrial diet might have changed since the onset of rapid climate change is an important step in understanding how polar bears may be reacting to climate change. We characterized the current terrestrial diet of polar bears …
Genetic Signatures Of A Demographic Collapse In A Large-Bodied Forest Dwelling Primate (Mandrillus Leucophaeus), Nelson Ting, Christos Astaras, Gail Hearn, Shaya Honarvar, Joel Corush, Andrew S. Burrell, Naomi Phillips, Bethan J. Morgan, Elizabeth L. Gadsby, Ryan L. Raaum, Christian Roos

It is difficult to predict how current climate change will affect wildlife species adapted to a tropical rainforest environment. Understanding how population dynamics fluctuated in such species throughout periods of past climatic change can provide insight into this issue. The drill (Mandrillus leucophaeus) is a large-bodied rainforest adapted mammal found in West Central Africa. In the middle of this endangered monkey’s geographic range is Lake Barombi Mbo, which has a well-documented palynological record of environmental change that dates to the Late Pleistocene. We used a Bayesian coalescent-based framework to analyze 2,076 base pairs of mitochondrial DNA across wild drill populations …
