“…We did not include birds in flight during surveys (Buckland et al ), and we did not sample waterfowl in dense fog or if winds exceeded 30 km/hour (Hagy and Kaminski ). Because observations constituted a non‐invasive field study (Pauli et al ), an animal care and use protocol was not required nor was a scientific collecting permit needed from the State of Tennessee. All data were collected under an agreement between the University of Tennessee at Knoxville and the USFWS.…”

Western Tennessee is an important region for waterfowl during non‐breeding periods, supporting >40% of the Mississippi Flyway population of American black ducks (Anas rubripes). Understanding habitat selection and activities of waterfowl during the non‐breeding period is important for directed habitat management on national wildlife refuges and in other wetlands important in meeting regional waterfowl conservation objectives. During November–February 2011–2013, we investigated diurnal habitat selection and activities of dabbling ducks (Anatini) among 5 common wetland types relative to emergent cover, water depth, and energetic carrying capacity (i.e., duck energy days [DEDs]) in western Tennessee, USA. We observed waterfowl daily and sampled food resources monthly at Tennessee and Cross Creeks National Wildlife Refuges. Mallard (Anas platyrhynchos), gadwall (A. strepera), northern pintail (A. acuta), and American green‐winged teal (A. carolinensis) selected moist‐soil wetlands over wooded, aquatic bed, and open water wetland types. Gadwall also selected deeper wetlands containing submersed aquatic vegetation. Foraging was the dominant activity of all dabbling ducks in mudflats and moist‐soil wetlands, and it was also dominant in wooded wetlands for green‐winged teal and gadwall. Deep, open water was avoided by dabbling ducks. Selection of wetland types was negatively correlated with increasing water depth and positively correlated with increasing emergent cover and DEDs. Shallowly flooded moist‐soil and wooded wetlands provide high‐energy foods and dense emergent cover, and are important to a diversity of dabbling ducks during winter. © 2017 The Wildlife Society.

“…Esta pode ser feita com base em amostras de DNA obtidas de diferentes fontes, como penas e sangue que representam formas não-destrutivas de amostragem biológica em aves 29,30 . Embora invasivas, as coletas de penas e de sangue implicam somente em um pequeno período de estresse aos animais, dado que é necessário realizar a contenção e a manipulação destes.…”

Gonçalves, BP; Wasko, AP. Genética da conservação aplicada ao tráfico ilegal de aves. Saúde, Ética & Justiça. 2013;18(Ed. Especial):79-83. RESUMO:Entre os animais silvestres envolvidos em tráfico/comércio ilegal no Brasil, as aves compreendem um dos grupos mais atingidos, especialmente devido a características como canto e colorido das penas. Atualmente, análises genéticas compreendem uma das formas mais eficazes de gerar dados para solucionar e minimizar os resultados de crimes ambientais e comércio ilegal de animais silvestres. Uma das análises genéticas que podem ser utilizadas com o intuito de subsidiar programas conservacionistas associados ao tráfico ilegal de aves refere-se à sexagem molecular, dado que neste grupo de vertebrados nem sempre é possível identificar o gênero por meio de caracteres morfológicos. A sexagem molecular pode ser feita com base em amostras de DNA obtidas de diferentes fontes, como penas e sangue, e posterior amplificação de regiões dos genes CHD-Z e CHD-W (chromo helicase-DNA binding). Os dados de perfis genéticos sexoespecíficos servem de subsídio a programas conservacionistas de manutenção e/ou reprodução em cativeiro e posterior soltura ou reintrodução dos animais em ambiente natural. PALAVRAS-CHAVE:Aves; Sexagem; Genética da conservação; Tráfico. * Este trabalho é relacionado à revisão bibliográfica da dissertação de mestrado da aluna Bianca Picado Gonçalves.

“…To gauge the potential effects of disturbance and contamination associated with oil and gas development on river otters in Southwestern Wyoming, we estimated their densities using non-invasive (Pauli et al, 2010) genetic sampling (Hansen et al, 2008;Guertin et al, 2012;Mowry et al, 2011;Brzeski et al, 2013) along several reaches of river. We mapped the distribution of river otter latrines in relation to habitat availability and disturbance and evaluated water quality by deploying electrical conductivity loggers at strategic points throughout the watershed.…”
