Using Artificial Nests To Study Nest Predation IN BIRDS

open access: yesThe American Biology Teacher, 2005
A simple and effective field exercise that demonstrates factors affecting predation on bird nests is described. With instructor guidance, students in high school biology or college-level biology, ecology, animal behavior, wildlife management or ornithology laboratory courses can collaborate to design field experiments related to nest depredation.

Nest Monitoring and Predator Visitation at Nests of Banded Dotterels [PDF]

open access: yesThe Condor, 2002
Abstract We used videocameras to monitor 39 nests of the Banded Dotterel (Charadrius bicinctus), a ground-nesting plover endemic to New Zealand that suffers from predation by introduced mammals. To test whether monitoring nests increased the chances of nests being visited by predators, 22 of the video-monitored nests were approached ...

Adaptive latitudinal variation in Common Blackbird Turdus merula nest characteristics [PDF]

open access: yes, 2014
Nest construction is taxonomically widespread, yet our understanding of adaptive intraspecific variation in nest design remains poor. Nest characteristics are expected to vary adaptively in response to predictable variation in spring temperatures over

The Biofuels Blueprint: Understanding the U.S. Renewable Fuel Standard

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT We provide a comprehensive review of the U.S. Renewable Fuel Standard (RFS), synthesizing nearly two decades of program evolution, market outcomes, and economic analysis. The RFS mandates minimum volumes of renewable fuel blending through a nested structure based on life‐cycle greenhouse gas reductions, enforced via tradeable Renewable ...

Reduced predation on roadside nests can compensate for road mortality in road‐adjacent turtle populations

open access: yesEcosphere, 2022
Turtles are killed on roads, yet there is little evidence of negative road effects on their abundances. We hypothesized that this could be due to reduced predation of turtle nests laid along roadsides, which could compensate for the effects of higher ...

Lack of effect of microhabitat charaacteristics on nest predation and brood parasitims in creamy-bellied thruss (Turdus Amaurochalinus) [PDF]

open access: yes, 2013
Nest predation and brood parasitism are key factors affecting nest survival in passerine birds. As a result, birds may select nest sites that minimize the probability of nests being found by predators or by brood parasites. Nevertheless, evidence remains

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

open access: yesThe Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Interspecific information on predation risk affects nest site choice in a passerine bird

open access: yesBMC Evolutionary Biology, 2018
Background Breeding site choice constitutes an important part of the species niche. Nest predation affects breeding site choice, and has been suggested to drive niche segregation and local coexistence of species. Interspecific social information use may,

Effects of habitat and livestock on nest productivity of the Asian houbara Chlamydotis macqueenii in Bukhara Province, Uzbekistan [PDF]

open access: yes, 2016
To inform population support measures for the unsustainably hunted Asian houbara Chlamydotis macqueenii (IUCN Vulnerable) we examined potential habitat and land-use effects on nest productivity in the Kyzylkum Desert, Uzbekistan.
