| predicted effects of landscape change, sea level rise, and habitat management on the extirpation risk of the hawaiian common gallinule (gallinula galeata sandvicensis) on the island of o'ahu. | we conducted a spatially explicit, stochastic, individually based population viability analysis for the hawaiian common gallinule (gallinula galeata sandvicensis), an endangered subspecies of waterbird endemic to fragmented coastal wetlands in hawai'i. this subspecies persists on two islands, with no apparent movement between them. we assessed extirpation risk for birds on o'ahu, where the resident gallinule population is made up of several fragmented subpopulations. data on genetic differentiat ... | 2018 | 29942683 |
| the common gallinule, gallinula galeata (aves: gruiformes: rallidae), as a new host for eimeria paludosa (apicomplexa: eimeriidae) in mexico. | up to now, four coccidian species have been identified in rallidae (aves: gruiformes): eimeria mongolica, e. alakuli, e. paludosa and e. porphyrulae. here, we described an eimeria species, e. paludosa, from a common gallinule (gallinula galeata) in mexico. oocysts were ovoid and wall pitted single-layered. a prominent micropyle was present, the oocyst residuum absent and the polar granule was present. on histological examination of tissues, endogenous stages (meronts, microgametocytes and macrog ... | 2020 | 32147622 |
| 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 |
| landscape genetics identifies streams and drainage infrastructure as dispersal corridors for an endangered wetland bird. | anthropogenic alterations to landscape structure and composition can have significant impacts on biodiversity, potentially leading to species extinctions. population-level impacts of landscape change are mediated by animal behaviors, in particular dispersal behavior. little is known about the dispersal habits of rails (rallidae) due to their cryptic behavior and tendency to occupy densely vegetated habitats. the effects of landscape structure on the movement behavior of waterbirds in general are ... | 2018 | 30250706 |
