Ocular morphology and morphometry of the great egret (Ardea alba): A comprehensive anatomical description

open access: yesThe Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is widely distributed, yet knowledge of its ocular morphology remains limited. This study described the morphometry and morphology of the eyeball and its accessory glands in six specimens using radiography, morphometry, light and scanning electron microscopy, and 3D scanning.

Cumulative Reproductive‐Lactation Burdens Induce a Systemic Immunometabolic Trade‐Off Between Milk Yield and Mammary Health of Dairy Cows

open access: yesAnimal Research and One Health, EarlyView.
A population‐scale longitudinal transcriptomic atlas reveals how lactation stage and parity reshape systemic gene regulation in dairy cows. Multiomics‐inspired analyses uncover dynamic immune and metabolic adaptations that contribute to reproductive longevity and sustained productivity across the bovine lifespan.

Ecological Reference Points for Atlantic Menhaden Established Using an Ecosystem Model of Intermediate Complexity

open access: yesFrontiers in Marine Science, 2020
Atlantic menhaden (Brevoortia tyrannus) are an important forage fish for many predators, and they also support the largest commercial fishery by weight on the U.S. East Coast. Menhaden management has been working toward ecological reference points (ERPs)

Forage Fish: From Ecosystems to Markets [PDF]

open access: yesAnnual Review of Environment and Resources, 2008
Fisheries targeting small-to-medium pelagic, so-called forage fish, impact on human food security and marine ecosystems. Because their operations are shrouded by the myth that forage fish are unsuitable for human consumption, the role of these fisheries in intensive food production is not well understood or appreciated.

String Figuring young children's perspectives of quality in English early childhood education and care

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.

Knowledge gaps and research directions in migration ecology for advancing the conservation of migratory songbirds

open access: yesBiological Reviews, EarlyView.
ABSTRACT Understanding migration ecology is essential for effective conservation of migratory species. To achieve a comprehensive understanding of the ecology of migrating species, it is necessary to study how species react to the complex interplay of intrinsic and extrinsic conditions when optimizing their migratory journey in terms of survival ...

Spatial and within-season variation in the diet of a declining seabird described through digital photography and citizen science

open access: yesAvian Conservation and Ecology
Understanding an animal’s diet is a crucial component of conservation, but diet data are often labor intensive to collect and are frequently scarce. Atlantic Puffins ( Fratercula arctica ; hereafter Puffins) are vulnerable to global extinction and have ...
