Grazing intensities and poultry litter fertilization levels on corn and black oat yield

open access: yesPesquisa Agropecuária Brasileira, 2012
The objective of this work was to assess the effect of poultry litter fertilization levels on corn and black oat yield using different grazing intensities, poultry litter levels (mixture of manure and bedding material) and a chemical fertilization level.

Dietary Echinacea purpurea Attenuates Oxidative Stress and Alters Cytokine Gene Expression Among Heat‐Stressed Broiler Chickens at High Altitude

open access: yesVeterinary Medicine and Science, Volume 12, Issue 6, November 2026.
Dietary Echinacea purpurea (0.75%) alleviated oxidative stress (↓NO, ↓MDA) and selectively upregulated IL‐10 and IFN‐γ expression in heat‐stressed broilers at high altitude, shifting the cytokine balance toward an anti‐inflammatory state without affecting telomere length.

Humans are not unique: difficult birth is common in placental mammals

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2214-2239, October 2026.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Trade‐offs in avian parental care: a review of theory and meta‐analysis of brood size manipulations

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2337-2358, October 2026.
ABSTRACT The selective forces shaping parental care have been studied for over 50 years. While theoretical and experimental work has yielded qualitative progress, the large body of empirical work testing predictions about parental investment based on life‐history trade‐offs has yet to be synthesized.

Application of close‐kin mark–recapture to an American black bear population using harvest samples

open access: yesEcological Applications, Volume 36, Issue 7, October 2026.
Abstract Close‐kin mark–recapture (CKMR) offers a promising alternative to traditional mark–recapture methods for estimating wildlife population parameters. CKMR estimates demographic parameters by identifying genetic relationships between individuals, effectively “recapturing” parental genotypes through their offspring's genetic profiles.
