Estimation of population age structure, daily survival rates, and potential to support dengue virus transmission for Florida Keys Aedes aegypti via transcriptional profiling.

open access: yesPLoS Neglected Tropical Diseases
Aedes aegypti is an important vector of dengue virus and other arboviruses that affect human health. After being ingested in an infectious bloodmeal, but before being transmitted from mosquito to human, dengue virus must disseminate from the vector ...

Good neighbors? Does aggregation of nests in an Arctic‐breeding shorebird influence daily survival rates?

open access: yesEcology and Evolution, 2023
AbstractOur current understanding of the factors that influence where birds nest is incomplete, yet such information is important for accurate demographic assessments. To address questions related to spatial distributions of shorebird nests and to evaluate factors that may affect nest distribution in these species, during 2017 and 2019, we studied a ...

Individual and Environmental Determinants of Daily Black Grouse Nest Survival Rates at Variable Predator Densities [PDF]

open access: yesAnnales Zoologici Fennici, 2010
Nest predation in ground nesting black grouse (Tetrao tetrix) inhabiting managed boreal forests is arguably the single most important cause of nesting failure. Little is known, however, about indirect effects of other factors, such as maternal or environmental properties, and to what extent maternal and habitat qualities interact with varying levels of

Nest daily survival rate of six Costa Rican urban birds

open access: yesThe Wilson Journal of Ornithology, 2020
The advance of urbanization in Neotropical countries has drastically changed or eliminated extensive areas of natural habitats. Despite these changes, some species breed in cities and adapt to urban conditions. Several variables, such as the type of nest, substrate, and height, as well as the distance to buildings at which nests are constructed, may ...

COVID-19 in a Dutch nursing home: a longitudinal retrospective care home level case study on infection rate, survival rate and daily functioning

open access: yesJournal of Clinical Medicine, 2023
Abstract Background: During the pandemic nursing homes in the Netherlands were heavily affected by COVID-19. The goal of this study was to assess the impact of COVID-19 on infection rate, survival rate and daily functioning over the course of 2 years among residents of a small nursing home in the South of the Netherlands, which was amongst the ...

Miniature temperature data loggers increase precision and reduce bias when estimating the daily survival rate for bird nests [PDF]

open access: yesJournal of Field Ornithology, 2021
Demographic studies of many bird species are challenging because their nests are cryptic, resulting in few nests being found. To maximize statistical power, methods are needed that minimize disturbance while yielding as much information per nest as possible.

Daily Survival Rates of Eggs in Artificial Ground and Shrub Bird Nests on Small Adriatic Islands

open access: yesArdeola, 2015
Predation may cause important losses to the biodiversity of small islands. In this study we analysed the predation pressure on clutches of nesting birds in two islands of the Zadar archipelago, Olib and Silba, which belong to an Important Bird Area in Croatia.

Helpers increase daily survival rate of Southern Lapwing ( Vanellus chilensis ) nests during the incubation stage [PDF]

open access: yesThe Wilson Journal of Ornithology, 2017
Abstract Cooperative breeding is characterized by reproduction in the presence of helpers. What impact these helpers have on the reproductive success of group members is one of the long-standing questions in the cooperative breeding literature.

Utilization of fermented Seligi leaf flour Phyllanthus buxifolius toward the specific growth rate, daily growth rate and survival rate of siam catfish (Pangasius pangasius)

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract Siam Catfish (Pangasius pangasius) is a freshwater fish commodity that has important economic value because of its fast growth and easily cultured. One way to increase catfish production is through fulfilling the nutritional requirements through the feed.
