Toward Numerical Modeling of Interactions Between Ice-Marginal Proglacial Lakes and Glaciers

open access: yesFrontiers in Earth Science, 2020
Global climate change is evidently manifest in disappearing mountain glaciers and receding and thinning ice sheet margins. Concern about contemporaneous proglacial lake development has spurred an emerging area of research seeking to quantitatively ...

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.

Calf management practices and associations with herd-level morbidity and mortality on beef cow-calf operations

open access: yesAnimal, 2016
The objective of this study was to investigate calf management practices on beef cow-calf operations and determine associations with herd-level morbidity and mortality of pre-weaned calves.

The effects of maternal calving date and calving interval on growth performance of beef calves

open access: yesSouth African Journal of Animal Science, 2000
This study was undertaken to investigate the growth performance of calves born to dams with different calving dates and calving intervals. Early calving dams produced calves with the lowest birth weights, the highest actual weaning weights and the highest pre-breeding heifer weights.

Beyond Protein Synthesis: The Multifunctional Role of Functional Amino Acids in Modulating Meat Quality in Ruminants

open access: yesAnimal Research and One Health, EarlyView.
Multifunctional roles of functional amino acids in regulating meat quality in ruminants: Functional amino acids (FAAs) regulate ruminant meat quality through multiple interconnected mechanisms, including antioxidant protection, metabolic regulation, signal transduction, structural support, and gene expression modulation.

Genetic parameters of growth in dairy cattle and associations between growth and health traits [PDF]

open access: yes, 2007
Body weight (BW) observations on dairy cattle taken on average 35 times between birth and 1,000 d of life were used to estimate daily heritabilities and predict daily breeding values for both pregnancy-adjusted BW (PABW) and growth rate.

High Rates of Return to Soccer After Primary Hip Arthroscopic Labral Repair for Femoroacetabular Impingement Syndrome

open access: yesArthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate return‐to‐sport (RTS) outcomes and patient‐reported outcomes in soccer players after primary hip arthroscopic labral repair for femoroacetabular impingement syndrome. Methods All patients undergoing primary hip arthroscopy with labral repair for femoroacetabular impingement syndrome from 2011 to 2022 were retrospectively reviewed ...

Calving Dynamics and the Potential Impact of Mélange Buttressing at the Western Calving Front of Thwaites Glacier, West Antarctica [PDF]

open access: yes
The western region of the wide Thwaites Glacier terminus is characterized by a near-vertical calving front. The grounding line at this western calving front (WCF) rests on a relatively high ridge, behind which exists a reverse-sloping bed; retreat of the

Relationship between Conception Date and Latitude in Muskoxen

open access: yesRangifer, 1997
It has been suggested that muskoxen calve earlier with increasing latitude but the available data do not seem to have been thoroughly analyzed. Therefore, estimated conception dates (K=657) from a wide range of latitudes were compared.

Early Modern Amateur Botany and Historical Biodiversity: An Interdisciplinary Approach to the Herbarium Ruperti (1698–1705)

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
The Herbarium Ruperti, compiled by the Lutheran theologian Georg Andreas Ruperti and containing ca. 1300 plants, represents one of the earliest comprehensive collections documenting the flora of northern Germany before the emergence of systematic botanical surveys.
