Response of roseate tern to a shoreline protection project on Falkner Island, Connecticut Response of roseate tern to a shoreline protection project on Falkner Island, Connecticut

Construction was initiated following the 2000 tern breeding season for Phase 1 of a planned two-phase "Shoreline Protection and Erosion Control Project" at the Falkner Island Unit of the USFWS Stewart B. McKinney National Wildlife Refuge located in Long Island Sound off the coast of Guilford, CT. When the Common Tern (Sterna hirundo) and federally endangered Roseate Tern (S. dougallii)...

Workshop: Western hemisphere network of bird banding programs Workshop: Western hemisphere network of bird banding programs

Purpose: To promote collaboration among banding programs in the Americas. Introduction: Bird banding and marking provide indispensable tools for ornithological research, management, and conservation of migratory birds on migratory routes, breeding and non-breeding grounds. Many countries and organizations in Latin America and the Caribbean are in the process of developing or have...

Mammals of South America, Volume 1, Marsupials, Xenarthrans, Shrews, and Bats Mammals of South America, Volume 1, Marsupials, Xenarthrans, Shrews, and Bats

The vast terrain between Panama and Tierra del Fuego contains some of the world?s richest mammalian fauna, but until now it has lacked a comprehensive systematic reference to the identification, distribution, and taxonomy of its mammals. The first such book of its kind and the inaugural volume in a three-part series, Mammals of South America both summarizes existing information and...

Current range of the eastern population of Painted Bunting (Passerina ciris). Part II: Winter range Current range of the eastern population of Painted Bunting (Passerina ciris). Part II: Winter range

The importance of wintering areas for Neotropical migrants is well established. The wintering range of the eastern population of Painted Bunting (Passerina ciris) is described in detail and presented in maps. The paper also discusses extralimital records from islands in the Caribbean Basin as well as scattered wintering individuals outside the winter range. The possibility of eastern...

Adaptive harvest management of North American waterfowl populations: a brief history and future prospects Adaptive harvest management of North American waterfowl populations: a brief history and future prospects

Since 1995, the US Fish and Wildlife Service has used an adaptive approach to the management of sport harvest of mid-continent Mallard ducks (Anas platyrhynchos) in North America. This approach differs from many current approaches to conservation and management in requiring close collaboration between managers and scientists. Key elements of this process are objectives, alternative...

Application of information theory methods to food web reconstruction Application of information theory methods to food web reconstruction

In this paper we use information theory techniques on time series of abundances to determine the topology of a food web. At the outset, the food web participants (two consumers, two resources) are known; in addition we know that each consumer prefers one of the resources over the other. However, we do not know which consumer prefers which resource, and if this preference is absolute (i.e

Fourfold polyphyly of the genus formerly known as Upucerthia, with notes on the systematics and evolution of the avian subfamily Furnariinae Fourfold polyphyly of the genus formerly known as Upucerthia, with notes on the systematics and evolution of the avian subfamily Furnariinae

The traditional avian subfamily Furnariinae, a group of terrestrial ovenbirds typical of the Andean and Patagonian arid zones, consists of the genera Furnarius, Cinclodes, Geositta, Upucerthia, Chilia, and Eremobius. We investigated phylogenetic relationships within the Furnariinae, with particular attention to the nine species of the genus Upucerthia, using nuclear and mitochondrial DNA...

Occupancy estimation and modeling with multiple states and state uncertainty Occupancy estimation and modeling with multiple states and state uncertainty

The distribution of a species over space is of central interest in ecology, but species occurrence does not provide all of the information needed to characterize either the well-being of a population or the suitability of occupied habitat. Recent methodological development has focused on drawing inferences about species occurrence in the face of imperfect detection. Here we extend those...

Quantifying the impact of longline fisheries on adult survival in the black-footed albatross Quantifying the impact of longline fisheries on adult survival in the black-footed albatross

1. Industrial longline fishing has been suspected to impact upon black-footed albatross populations Phoebastria nigripes by increasing mortality, but no precise estimates of bycatch mortality are available to ascertain this statement. We present a general framework for quantifying the relationship between albatross population and longline fishing in absence of reliable estimates of...

Hierarchical spatial models of abundance and occurrence from imperfect survey data Hierarchical spatial models of abundance and occurrence from imperfect survey data

Many estimation and inference problems arising from large-scale animal surveys are focused on developing an understanding of patterns in abundance or occurrence of a species based on spatially referenced count data. One fundamental challenge, then, is that it is generally not feasible to completely enumerate ('census') all individuals present in each sample unit. This observation bias...

Ra and Rn isotopes as natural tracers of submarine groundwater discharge in Tampa Bay, Florida Ra and Rn isotopes as natural tracers of submarine groundwater discharge in Tampa Bay, Florida

A suite of naturally occurring radionuclides in the U/Th decay series (222Rn, 223,224,226,228Ra) were studied during wet and dry conditions in Tampa Bay, Florida, to evaluate their utility as groundwater discharge tracers, both within the bay proper and within the Alafia River/estuary — a prominent free-flowing river that empties into the bay. In Tampa Bay, almost 30% of the combined...
