Perspectives on the Effect of Incubation Temperature on Pine Snake Hatchlings

open access: yesEthology, EarlyView.
Effect of timing of egg‐laying and incubation temperature on the possible phenology of events for early egg‐laying females (laying June 15, the earliest laying date), the mid‐laying date (July 4), and late egg‐laying females (July 17, the latest egg‐laying date). Based on data from many papers.

Expression analysis for candidate genes associated with eggshell mechanical property

open access: yesJournal of Integrative Agriculture, 2016
: Damaged eggshells result in losses of eggs. The genetic mechanism of variable eggshell strength is still unclear. The current study was conducted to verify whether the eggshell calcification related genes, CALB1, SPP1, DMP4, BMP2 and SLIT2, were ...

Layer performances, eggshell characteristics and bone strength in three different housing systems

open access: yesBiotechnology in Animal Husbandry, 2013
The aim of this study was to determine the effects of three different housing systems for laying hens (cages, barn and organic) on layer performances, eggshell characteristics and bone strength. In each system, the same strain of laying hens (Hyline Brown?) was housed in agreement with current European regulation and the hens were fed on ...

The oral microbiota and periodontal health in orthodontic patients

open access: yesPeriodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.

“She Was My Egg Donor, Not My Mom”: Using Attribution Theory to Understand How Adult Daughters Manage Their Low‐Quality Daughter‐Mother Relationship

open access: yesPersonal Relationships, Volume 33, Issue 1, March 2026.
ABSTRACT This study employs attribution theory to examine how adult daughters from low‐income backgrounds perceive and manage low‐quality daughter‐mother relationships. Using in‐depth interviews and flexible coding, we analyzed how daughters (n = 42) attribute locus, responsibility, specificity, and stability. Daughters often located control internally

Flooding and a complex predator community drive American oystercatcher nest and chick survival in Virginia

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We investigated low American oystercatcher (Haematopus palliatus) productivity in the Virginia barrier islands, which historically supported high oystercatcher reproductive success. We found that chick survival was lower than nest survival, and that management may need to adapt to address evolving threats from coastal flooding and a multi‐guild ...

Organochlorine Pesticide Contamination and its Potential Effects on Eggshell Characteristics of Dickcissels (Spiza americana) [PDF]

open access: yes, 2008
Dickcissels (Spiza americana) are small, sparrow-like songbirds that nest in grasslands in the U.S. and winter in Venezuela. Fanners in Venezuela intentionally spray dickcissel flocks with organochlorine (DC) and other illegal pesticides in an attempt to
