Factors affecting larval growth and development of the boreal chorus frog Pseudacris maculata
DownloadFall 2010
The boreal chorus frog (Pseudacris maculata) is a widespread species but we know little of its ecology. I examined the nature and existence of competitive mechanisms operating between larvae of the boreal chorus frog and wood frog (Lithobates sylvaticus) from field, mesocosm and laboratory venues...

Cyanobacteria occur worldwide in environments that contain water and sunlight. They are crucial, positive players in carbon, oxygen and nitrogen cycling and function as producers of biosynthetic products such as biofuels. To optimize these processes, understanding mechanisms by which...
