Biogeographical Approaches for Studying Species Invasion
Many of the most notorious biological invasions occur at continent-wide or global scales but studies investigating mechanisms enhancing species invasions are often conducted at small spatial scales. Moreover, the contribution of mechanisms facilitating invasion might also vary across a geographical …

Analysis of laminated sediments from Lake DV09, northern Devon Island, Nunavut, Canada
… sediments, providing a 1600-year record of climate variability. A minerogenic lamina deposited during the annual thaw period and a thin deposit of organic matter deposited during the summer and through the winter, together form a clastic-organic couplet each year. The thinnest varves occur …

Connecting above- and belowground effects of climate warming on bumble bee health
<p>Climate warming has been identified as one of the primary factors causing worldwide pollinator declines. One of the most at-risk groups of pollinators is bumble bees (<em>Bombus</em> spp.). Bumble bees are common, widespread, and key pollinators of a wide range of crops and wild plants. Although …

An Analysis of the Effects of Temperature and Other Environmental Factors on Microorganismal Productivity within Aquatic Ecosystems using Long-Term Data from Various Lter and Ilter Sites
<p>Global climate change is a phenomenon resulting in more extreme weather patterns and species diversity loss. In this study, I explore the impacts of climate change on regional patterns of microbial productivity. Variation in microbial productivity was explained using temperature, salinity, and …

Effects of temperature and location on the photosynthesis-irradiance relationship of the seagrass Halophila ovalis
… two sites within each location. Plants were acclimated to three different temperatures, 17°C, 23°C and 28°C, which relatively covered each locations average minimum and maximum temperature. P-I relationships of whole plants were determined in sealed chambers, with oxygen concentrations measured …
