[distribution of aquatic and raptor birds in a freshwater artificial pond of baja california sur, mexico].	we determined the taxonomic composition and spatial-temporal distribution of aquatic and raptor birds in a freshwater artificial pond of el centenario, baja california sur, méxico, during 24 biweekly censuses (april, 1998 to march, 1999). the pond is particularly attractive for birds because of its variety of food items. a total 25,563 records of 69 species were done, among them the first report of chlidonias niger and phalaropus tricolor for the region. species richness and abundance were deter ...	2006	12189794
modelling wetland bird response to water level changes in the lake ontario - st. lawrence river hydrosystem.	lake ontario and st. lawrence river (losl) wetland bird abundance and diversity are greatly influenced by lake and river hydrology. our study used an interdisciplinary ecosystem approach, blending avian and plant ecology, ecohydraulic, statistical ecology and modelling to evaluate potential impacts of water level fluctuations on indicator species representative of the wetland breeding bird assemblages in the entire losl freshwater system. multi-year (2000-2003) bird surveys captured bird distrib ...	2006	16518674
post-hatching growth and development of the pectoral and pelvic limbs in the black noddy, anous minutus.	the black tern (anous minutus) uses a semi-precocial growth strategy. terrestrial locomotor capacity occurs soon after hatching, but pectoral limb development is delayed and flight is not possible until about post-hatching day 50. a growth series (hatchlings to fledglings) was used to explore how limb musculoskeletal development varied with body mass. in the pelvic limb, bone lengths scaled isometrically or with negative allometry. gastrocnemius muscle mass and the failure load and stiffness of ...	2008	16901740
multispecies benefits of wetland conservation for marsh birds, frogs, and species at risk.	wetlands conserved using water level manipulation, cattle exclusion, naturalization of uplands, and other techniques under the north american waterfowl management plan ("conservation project wetlands") are important for ducks, geese, and swans ("waterfowl"). however, the assumption that conservation actions for waterfowl also benefit other wildlife is rarely quantified. we modeled detection and occupancy of species at sites within 42 conservation project wetlands compared to sites within 52 simi ...	2018	29428650
