Avian Research, 2018 Background Nest predation is usually the main cause of bird nest failure. ‘Predation avoidance hypothesis’ of nest-site selection predicts that birds should prefer nest-sites with higher nesting success.

Avian Research, 2021 Background Patterns of rarity can be explained by reproductive rates, levels of endemism, and habitat specificity, and knowledge on these parameters is important to understand the levels of vulnerability of each species and to formulate conservation ...

Daily survival rates of ruffed grouseBonasa umbellusin northern Minnesota
Wildlife Biology, 2003 We radio-marked 56 ruffed grouse Bonasa umbellus in northern Minnesota, USA, during 1963–1965 and 2001–2002. Of these, we estimated the daily survival rate of 49 individuals (32 females and 17 males; of which 27 were grey phase and 22 were red phase) during the breeding and non-breeding seasons.

Correcting Nesting-Success Estimates for Observer Effects: Maximum-Likelihood Estimates of Daily Survival Rates With Reduced Bias [PDF]
The Auk, 2000 AbstractWe develop a statistical method that simultaneously estimates daily survival rate and observer effect. We used Monte Carlo simulation to (1) evaluate the performance of the model, (2) compare model performance with models that ignore observer effects, and (3) evaluate methods of choosing between competing models of survival.

Mark-recapture estimates of daily survival rates of two damselflies (Coenagrion puella and Ischnura elegans) [PDF]
Canadian Journal of Zoology, 2001 Male-biased operational sex ratios are very common in sexually mature dragonflies. These may be due to differential survival or differences in time spent at the breeding site by the sexes. Because most studies are carried out at the breeding site, these two processes can be measured as survival rates or recapture rates using modern capturemark ...

A non-interventional multicenter study to document the implants success and survival rates in daily dental practices of the CONELOG screw-line implant [PDF]
Clinical Oral Investigations, 2018 This multicenter prospective non-interventional study evaluated the success and survival of the CONELOG implants inserted according to the standard protocol with one- or two-step surgery in daily practice three years after loading. Changes of soft tissue and bone level over time, esthetical outcome, and patient satisfaction were assessed.The study ...

AN ATTEMPT TO ALLEVIATE AFLATOXICOSIS ON NILE TILAPIA FISH BY DIETARY SUPPLEMENTATIONS WITH CHICKEN-HATCHERY BY·PRODUCTS(EGG SHELLS)AND SHRIMP PROCESSING WASTES (SHRIMP SHELLS) ON: 1· FISH PERFORMANCE AND FEED AND NUTRIENTS UTILIZATION. [PDF]
Journal of Animal and Poultry Production, 2004 This experiment was conducted to study the drastic effects of graded levels of aflatoxin-B. on growth performance, survival rate, feed and nutrients utilization, and carcass composition of Nile tilapia, O. niloticus fingerlings.

Factors affecting Bobolink nest survival across grassland types
Avian Conservation and Ecology, 2020 Grassland birds, including Bobolinks (Dolichonyx oryzivorus), have experienced steep population declines across their breeding range in North America. Because of these declines, Bobolinks were listed as threatened by the Ontario and Canadian governments.
