Exercise can help modulate human gut micriobiota - Robert McFadzean - 2014

Jan. 8, 2014

Abstract Moderate exercise has been shown to be beneficial to health in many ways, including reducing stress, building a stronger immune system and increasing cardiovascular health. Recent studies in the human gut microbiome have demonstrated benefits of certain microorganisms in aiding human pathogen resistance and reduction of inflammation. The hypothesis...

Adult barn swallow and its nest with young ones.

Changes in parental provisioning rates across the nestling period in response to ectoparasites in the North American barn swallow Hirundo rustica erythrogaster - Matt Aberle - 2014

Jan. 8, 2014

Abstract While parasites have long been documented, the large fitness cost to their hosts has only recently been addressed via studies of ecology and evolution. Large fitness costs apply to altricial nestlings confined to the nest and completely dependent on parental care. These costs are often passed on to their...

The Atacama Desert.

Dew Formation and Water Availability at High Elevation in the Atacama Desert, Chile - Zachary R. Schubert - 2014

Jan. 8, 2014

Abstract The Atacama Desert, Chile, is among the least habitable environments on the planet largely because of its extreme aridity; nevertheless, ecosystems continue to function in many locations there, at least intermittently when water is available. This study addresses the question of whether dew could ever form at high-elevation sites...

Guiding building owners towards energy conservation measures - Sean Kuusinen - 2014

Jan. 8, 2014

Abstract Energy conservation measures have been identified as the most cost effective way to reduce carbon emissions. However, a lack of available information regarding energy conservation prevents building owners from investing in energy efficiency. This research provides the groundwork for supplying building owners with a simple model to guide retrofit...

Lowland tropical forest.

The Effects of Land-­‐Cover Change and Topography on Nitrogen Cycling in a Lowland Tropical Forest of Costa Rica - Maggie Mae Kriz - 2014

Jan. 8, 2014

Abstract While topographic variability and land-­‐use change have been shown to alter nutrient availability in diverse tropical landscapes, the combined effects of these two factors on nitrogen (N) cycling are poorly understood. In all ecosystems, however, it is vital to understand controls on N availability, as N is an element...

A cuckoo catfish.

Host-Parasite Interactions: The Cuckoo Catfish and Non-Sympatric Hosts - Anna Vinton - 2014

Jan. 8, 2014

Abstract The cuckoo catfish ( Synodontis multipunctatus ) from Lake Tanganyika in Africa parasitizes mouth-brooding cichlid fishes (catfish eggs get picked up and incubated in the mouths of cichlid females, where the catfish young feed on cichlid eggs). I examined the impact of parasitism by the cuckoo catfish on an...

Endler's Guppy (Poecilia wingei)

Mate Choice and Hybridization: Comparing the Endler’s Guppy (Poecilia wingei) and the Common Guppy (Poecilia reticulata) - Chloe T. Ramsay - 2014

Jan. 8, 2014

Abstract The present study addresses the question of whether or not two guppy species, the Endler’s guppy ( Poecilia wingei ) and the common guppy ( Poecilia reticulata ) are able to mate and produce offspring. The question of interest is in the context of the conservation of the Endler’s...

Soil, tall fescue, and fungal shoot endophyte.

Symbiosis Between Tall Fescue and a Fungal Shoot Endophyte Affects Soil Microbial Communities - Xavier Rojas - 2014

Jan. 8, 2014

Abstract The symbiosis between tall fescue ( Festuca arundinaceum ) and a shoot-specific fungal endophyte ( Neotyphodium coenophialum ) has been relatively well studied but little attention has been given to how this relationship may impact the soil microbial community. Understanding how the symbiosis may structure soil microbial communities is...
