Large bodies of water, such as the Great Lakes in North America, are potential barriers to migrating bats. Islands may be used as stopover sites by bats crossing the Great Lakes as stopover sites, or included in crossing routes to reduce the distance flown over open water. I predicted that stopover use by migrating bats would result in higher activity on Great Lakes islands during late-season migration than at mainland sites. I monitored acoustic activity at 11 sites across four locations in Ontario: Amherst and Pelee islands, Kingston and Pinery Provincial Park during the summer (June and July), and during …
Population Of Northern Leopard Frogs (Rana Pipiens) Migrating Between The Ney Frog Pond And The Minnesota River Valley For Spring Breeding, Rebecca Madison Pollack
Population Of Northern Leopard Frogs (Rana Pipiens) Migrating Between The Ney Frog Pond And The Minnesota River Valley For Spring Breeding, Rebecca Madison Pollack
Journal of Undergraduate Research at Minnesota State University, Mankato
The Northern Leopard Frogs (Rana pipiens) found at the Ney Nature Center (NNC) are particularly important to the NNC, as they are the initial population of frogs found deformed in 1995. As bio-indicators, frog populations can be used to assess the health of their surrounding environment. This study used standard herpetological field methods to gain a population estimate of Northern Leopard Frogs and the migration route used by these frogs as they moved up the bluffs of the Minnesota River Valley from their wintering site to the Ney Frog Pond for spring breeding. The results gathered provide the Ney Environmental …

Natural riverbeds in arid regions of Central Asia play an important role in waterbird migration. However, agricultural irrigation in the Aral Sea basin, in combination with climate change, is leading to wetland habitat loss. In this study, we consider the importance of the 2 largest river systems in this region during postbreeding movements and compare waterbird assemblages in relation to habitat parameters between the Amu-Darya and Syr-Darya rivers. In the second half of August 2011, we counted waterbirds along 125 and 106 km of the Amu-Darya and Syr-Darya rivers, respectively. Both rivers showed a high similarity of richness indices. Analysis …
