Glacier calving observed with time-lapse imagery and tsunami waves at Glaciar Perito Moreno, Patagonia

Journal of Glaciology, 2018
Calving plays a key role in the recent rapid retreat of glaciers around the world. However, many processes related to calving are poorly understood since direct observations are scarce and challenging to obtain.

Pilot Study: Exploring the Feasibility of Individual Voluntary Waiting Period Settings Using Postpartum Recovery Indicators in Dairy Cows. [PDF]

Animals (Basel)
This study aimed to identify hematological markers that can objectively assess postpartum recovery in dairy cows, which is essential for determining an individualized voluntary waiting period (VWP).

Iceberg Calving: Regimes and Transitions

Annual Review of Earth and Planetary Science, 2023
Uncertainty about sea-level rise is dominated by uncertainty about iceberg calving, mass loss from glaciers or ice sheets by fracturing. Review of the rapidly growing calving literature leads to a few overarching hypotheses.

Meltwater drainage and iceberg calving observed in high-spatiotemporal resolution at Helheim Glacier, Greenland

Journal of Glaciology, 2022
Marine-terminating glaciers lose mass through melting and iceberg calving, and we find that meltwater drainage systems influence calving timing at Helheim Glacier, a tidewater glacier in East Greenland.

Association between age at first calving and lactation performance, lactation curve, calving interval, calf birth weight, and dystocia in Holstein dairy cows.

PLoS ONE, 2021
In the present study, records on 115,291 heifers distributed in 113 herds were used to investigate the association between age at the first calving (AFC) and lactation performance, lactation curve, the length of the first calving interval (CI), calf ...

Changes of Acid-Base Variables in Dairy Cows with Chronically Implanted Fetal and Maternal Catheters during Late Gestation and Calving

Animals, 2022
The objective of the present study was to evaluate the changes in maternal and fetal arterial acid-base variables withdrawn from catheterized dams and fetuses during the last days before and during calving.

Calving Multiplier Effect Controlled by Melt Undercut Geometry

Journal of Geophysical Research: Earth Surface, 2021
Quantifying the impact of submarine melting on calving is central to understanding the response of marine‐terminating glaciers to ocean forcing. Modeling and observational studies suggest the potential for submarine melting to amplify calving (the ...

Effect of Soy Lecithin Supplementation in Beef Cows before Calving on Colostrum Composition and Serum Total Protein and Immunoglobulin G Concentrations in Calves

Animals, 2020
The aim of this study was to investigate the impact of soy lecithin supplementation in beef cow’s nutrition on colostrum composition and serum concentrations of immunoglobulin G (IgG) and serum total protein (STP) in calves.

Analgesia during Parturition in Domestic Animals: Perspectives and Controversies on Its Use

Animals, 2022
This article analyzes the physiological role of pain during parturition in domestic animals, discusses the controversies surrounding the use of opioids, non-steroidal anti-inflammatory drugs (NSAIDs), and local analgesics as treatments during labor, and ...

Intravaginal Devices and GNSS Collars with Satellite Communication to Detect Calving Events in Extensive Beef Production in Northern Australia

Remote Sensing, 2020
Observing calves at birth may help to identify risk factors for, and reduce, calf loss in extensive beef systems. The objectives of this study were to: (1) evaluate two commercial satellite birth alert systems to enable the observation of newborn calves ...
