Auditory evoked potentials were recorded from the surface of the brain in young swamp and song sparrows. Responses to pure tones indicate that both species have similar auditory sensitivity during the sensitive period for song learning. Responses to the song syllables extracted from the normal adult song of both species show evidence of hemispheric differences for swamp sparrows listening to co...

We modeled surface wetness at high resolution, using a dynamic hydrology model, to predict flood and swamp water mosquito abundances. Historical meteorologic data, as well as topographic, soil, and vegetation data, were used to model surface wetness and identify potential fresh and swamp water breeding habitats in two northern New Jersey watersheds. Surface wetness was positively associated wit...

—We examined the distribution and abundance of the Coastal Plain Swamp Sparrow (Melospiza georgiana nigrescens) at previously occupied sites and points within potential habitat. We found Swamp Sparrows throughout their formerly documented range except in southern Chesapeake Bay. Swamp Sparrows were most common in the Mullica River region of New Jersey where we detected individuals at 78% of sys...

1. The coastal peat swamp forests of Sarawak, Malaysian Borneo, are undergoing rapid conversion, predominantly into oil palm plantations. This wetland ecosystem is assumed to have experienced insignificant disturbance in the past, persisting under a single ecologically-stable regime. However, there is limited knowledge of the past disturbance regime, long-term functioning and fundamentally the ...

Size distribution, sex ratio and use of burrows of the burrowing toad Rhinella fernandezae were studied in Buenos Aires province, Argentina. Two sites separated by approximately 300 m were studied: one was a road next to a swamp, and the other a garden of a country house located further from the swamp. We identified toad burrows, and individuals were sexed, measured and given an individual mark...

We observed the survivorship and distribution of larvae and pupae of Anopheles gambiae s.l. Giles immature stages in three habitats (rock pools, swamp, and puddles) in Banambani village. Mali, West Africa, during the mid-rainy season of 2000. Horizontal life tables were constructed for immatures in the laboratory. Times spent in the various immature stages were determined, and laboratory surviv...

Studying infrequent phenomena (e.g. hurricanes) and slow processes (e.g. forest regeneration) greatly challenges the ecological techniques of real-time studies. By combining the two relatively new approaches of paleotempestology and fine-resolution palynology, this study provides insight into the impacts of hurricanes and the post-hurricane regeneration of forests. I analyzed a 5-m sediment cor...

The Goshen Swamp, a fourth order blackwater creek in southeastern North Carolina, was clearcut of 130 acres of riparian and seasonally flooded forest in late May through September 1998. Downstream water quality had been monitored monthly for 212 years before the clearcut, during the clearcut, and for two years following the clearcut. The objective of this paper was to test the hypothesis that c...
