Reconstructing historical habitat data with predictive models Read More: http://www.esajournals.org/doi/abs/10.1890/13-0327.1 Reconstructing historical habitat data with predictive models Read More: http://www.esajournals.org/doi/abs/10.1890/13-0327.1
Historical vegetation data are important to ecological studies, as many structuring processes operate at long time scales, from decades to centuries. Capturing the pattern of variability within a system (enough to declare a significant change from past to present) relies on correct assumptions about the temporal scale of the processes involved. Sufficient long-term data are often lacking...

Consuming fire ants reduces northern bobwhite survival and weight gain Consuming fire ants reduces northern bobwhite survival and weight gain
Northern bobwhite quail, Colinus virginianus (L.) (Galliformes: Odontophoridae), population declines are well documented, but pinpointing the reasons for these decreases has proven elusive. Bobwhite population declines are attributed primarily to loss of habitat and land use changes. This, however, does not entirely explain population declines in areas intensively managed for bobwhites...

Age-Ratios and Condition of En Route Migrant Blackpoll Warblers in the British Virgin Islands Age-Ratios and Condition of En Route Migrant Blackpoll Warblers in the British Virgin Islands
The en route migration ecology of Blackpoll Warblers (Setophaga striata) is poorly understood, yet intriguing. Blackpoll Warblers undertake the longest open water migration of any wood warbler species, traveling from northeastern North America to South America, with the first potential landfall being the West Indies. This migration requires substantial energy reserves and subjects...

Trends in the capture fisheries in Cuyo East Pass, Philippines Trends in the capture fisheries in Cuyo East Pass, Philippines
Findings are presented of a comprehensive analysis of time series catch and effort data from 2000 to 2006 collected from a multi-species, multi-gear and two-sector (municipal and commercial) capture fisheries in Cuyo East Pass, Philippines. Multivariate techniques were used to determine temporal variation in species composition and gear selectivity that corresponded with annual trends in...

Age estimation of burbot using pectoral fin rays, brachiostegal rays, and otoliths Age estimation of burbot using pectoral fin rays, brachiostegal rays, and otoliths
Throughout much of its native distribution, burbot (Lota lota) is a species of conservation concern. Understanding dynamic rate functions is critical for the effective management of sensitive burbot populations, which necessitates accurate and precise age estimates. Managing sensitive burbot populations requires an accurate and precise non-lethal alternative. In an effort to identify a...

Gear and seasonal bias associated with abundance and size structure estimates for lentic freshwater fishes Gear and seasonal bias associated with abundance and size structure estimates for lentic freshwater fishes
All freshwater fish sampling methods are biased toward particular species, sizes, and sexes and are further influenced by season, habitat, and fish behavior changes over time. However, little is known about gear-specific biases for many common fish species because few multiple-gear comparison studies exist that have incorporated seasonal dynamics. We sampled six lakes and impoundments...

Survival of female white-cheeked pintails during brood rearing in Puerto Rico Survival of female white-cheeked pintails during brood rearing in Puerto Rico
Anas bahamensis (White-cheeked Pintail) is widely distributed across the Caribbean islands and South America. The species is classified as threatened in Puerto Rico and a species of least concern across most of its range. Little demographic data exist for the species, particularly during the breeding season. During 2000-2002, we radiomarked 31 incubating females at the Humacao Nature...

Assessment of lesser prairie-chicken use of wildlife water guzzlers Assessment of lesser prairie-chicken use of wildlife water guzzlers
Man-made water sources have been used as a management tool for wildlife, especially in arid regions, but the value of these water sources for wildlife populations is not well understood. In particular, the value of water as a conservation tool for Lesser Prairie-Chickens (Tympanuchus pallidicinctus) is unknown. However, this is a relevant issue due to a heightened conservation concern...

Preliminary testing of flow-ecology hypotheses developed for the GCP LCC region Preliminary testing of flow-ecology hypotheses developed for the GCP LCC region
The Ecological Limits of Hydrological Alteration (ELOHA) framework calls for the development of flow-ecology hypotheses to support protection of the flow regime from ecologically harmful alteration due to human activities. As part of a larger instream flow project for the Gulf Coast Prairie Landscape Conservation Cooperative (GCP LCC), regional flow-ecology hypotheses were developed for...
