Sex Ratio Modulates Reproductive Output and Dung Burying Behavior in Dung Beetle Gymnopleurus sturmi (Macleay, 1821) (Coleoptera: Scarabaeidae)

open access: yesEcology and Evolution
Dung beetles are important ecosystem engineers as they play an important role in recycling faces from animals. Dung beetles have evolved different behaviors, including dung ball rolling for their egg and developing offspring.

Instability of Anisotropic Fermi Surfaces in Two Dimensions

open access: yes, 1997
The effect of strong anisotropy on the Fermi line of a system of correlated electrons is studied in two space dimensions, using renormalization group techniques. Inflection points change the scaling exponents of the couplings, enhancing the instabilities

Additional Observations on \u3ci\u3eTachypompilus Ferrugineus\u3c/i\u3e With Emphasis on Male Behavior (Hymenoptera: Pompilidae) [PDF]

open access: yes, 2017
An aggregation of 11 males and 5 females of Tachypompilus ferrugineus was studied during August and September 1989 at a 2 m-high cemetery monument i Syracuse, NY. Male perching behavior and male-male and male-female interactions are described.

Fluid Biomarkers of Disease Burden and Cognitive Dysfunction in Progressive Supranuclear Palsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Identifying objective biomarkers for progressive supranuclear palsy (PSP) is crucial to improving diagnosis and establishing clinical trial and treatment endpoints. This study evaluated fluid biomarkers in PSP versus controls and their associations with regional 18F‐PI‐2620 tau‐PET, clinical, and cognitive outcomes.

USING BEHAVIOR AND SPACE USE OF RACCOONS TO INDIRECTLY ASSESS THE NATURE OF NEST PREDATION

open access: yesWildlife Society Bulletin, 2015
: Nest predation has been identified as a leading cause of wild turkey (Meleagris gallopavo; hereafter, turkey) reproductive failure and raccoons (Procyon lotor) are often implicated as important nest predators.

Risk assessment of wildlife-watching tourism in an important endangered loggerhead turtle rookery

open access: yesEndangered Species Research, 2021
Wildlife-watching tourism is a non-exploitative activity that can contribute to sustainable economic development of coastal communities. However, it is important to assess the potential impact and implement best practices to mitigate any negative effects

Sleep and nesting behavior in primates: A review [PDF]

open access: yesAmerican Journal of Physical Anthropology, 2018
AbstractSleep is a universal behavior in vertebrate and invertebrate animals, suggesting it originated in the very first life forms. Given the vital function of sleep, sleeping patterns and sleep architecture follow dynamic and adaptive processes reflecting trade‐offs to different selective pressures.Here, we review responses in sleep and sleep‐related

Hip Morphology–Based Osteoarthritis Risk Prediction Models: Development and External Validation Using Individual Participant Data From the World COACH Consortium

open access: yesArthritis Care &Research, EarlyView.
Objective This study aims to develop hip morphology‐based radiographic hip osteoarthritis (RHOA) risk prediction models and investigates the added predictive value of hip morphology measurements and the generalizability to different populations. Methods We combined data from nine prospective cohort studies participating in the Worldwide Collaboration ...

Reticence or vigilance at the nest: a cruel bind for the endangered Black-capped Vireo

open access: yesAvian Conservation and Ecology, 2017
Breeding birds vocalize to find mates and establish and defend territories, but these same critical communications may also attract predators or brood parasites, placing birds in a cruel bind.
