The role of abiotic and biotic interactions in deep-sea benthic habitats of the northeastern Gulf of Cadiz
… of the Alborán Domain with the North African and South Iberian margins, which ultimately promotes hydrocarbon-rich fluid venting, among other geological processes. Regarding oceanography, the single and interactive effects of the Eastern North Atlantic Central Water and of the Mediterranean …

Genetic diversity and distribution of the ringed salamander (Ambystoma annulatum) across multiple spatial scales
… distributions are governed by a complex suite of abiotic and biotic interactions that govern movement of individuals and are variable through time and space. These dynamic processes, such as shifts in temperature and precipitation regimes throughout geologic time, in conjunction with the species …

Tree community assembly and biogeochemical processes along an elevational gradient in western Panama
… remarkable contributions to global diversity and C cycle regulation. Understanding factors responsible of TMF dynamics are critical to predicting their plant community response to global change. Elevational and environmental gradients are key elements in our understanding of the effect of …

Dynamics of phytoplankton community composition in the western Gulf of Maine
… community composition to marine biogeochemistry and ecosystem processes and motivated by the need to understand their distributions on regional to global scales. The ultimate goal was to predict surface phytoplankton communities using satellite remote sensing by relating marine habitats--defined …

Spatial and temporal influences on the physiological condition of invasive silver carp
Bighead (Hypophthalmichthys nobilis) and silver carp (H. molitrix) (hereafter, Asian carp) are invasive species that have the potential to negatively influence non-native freshwater systems. Following their introduction to the United States in the early 1970s, Asian carp have become established in …

Effects of abiotic and biotic factors on population dynamics of brook trout (<i>Salvelinus fontinalis</i>) within Shenandoah National Park, Virginia
… activity, including habitat destruction and climate change. Monitoring aquatic ecosystems is important so that we can better understand and remedy the consequences of these threats. Native fish species found within these aquatic ecosystems are often used as quality indicators to determine …
