Temperate forest ecosystems are most extensively found throughout the Northern Hemisphere, and less extensively in the Southern Hemisphere. The specific regions containing temperate forests include Europe, North America, Asia, South America, Australia, and New Zealand. Northern temperate forests are often composed of deciduous trees that drop their...

For over 70 years, closed topographic depressions developed in siliciclastic rocks of the Cumberland Plateau have been hypothesized to form via collapse of rock into caverns formed in the carbonate-rich rocks below. We made observations of surface characteristics and applied geophysical methods across two of these depressions on the western part of...

Science, Technology, Engineering, and Mathematics (STEM) fields play important roles in creating knowledge for society and pathways to power, resources, and authority for scientists, yet women, and people of color, have historically been underrepresented in STEM fields. Various approaches have attempted to diversify the pipeline into these fields....

This research examines the integration and potential uses of linkages between climate dynamics, savanna vegetation and landscape level processes within a highly vulnerable region, both in terms of climate variability and social systems. We explore the combined applications of two time-series methodologies: (1) climate signals detected in tree ring...

If current temperature trends continue and increase as predicted by general circulation models, the persistence and migration of sugar maple (Acer saccharum) at its northern limit will become crucial to its continued existence in North America. Specifically, anthropogenic warming may affect germination success and growth of sugar maple. To evaluate...

In academia, publication productivity, defined as the number of peer-reviewed articles published and the frequency of citations, is a primary factor in the assessment of tenure and promotion. One of the most cited gender differences in academia is the “productivity puzzle,” which suggests that women publish less than men, thereby affecting every as...

The goal of this research was to assess the health and physiological stress of understory balsam fir (Abies balsamea) seedlings and saplings within Lake Superior Provincial Park (LSPP) in Ontario, Canada to provide an indication of the degree to which they are affected by ambient light levels. The photochemical efficiency of balsam fir photosystem...
