The future is Nye: an extension of the perfect plastic approximation to tidewater glaciers

Journal of Glaciology, 2016
Accurate modeling of calving glaciers relies on knowledge of many processes (ice flow, surface/submarine melting, calving, mélange interaction) and glacier-specific factors (air temperature, ocean circulation, precipitation rate, glacier geometry) that ...

A Tracking‐By‐Detection Framework to Automatically Count Rare and Elusive Megafauna in Aerial Video Surveys

Remote Sensing in Ecology and Conservation, EarlyView.
Monitoring programs of vulnerable megafauna increasingly rely on aerial surveys from drones or planes fitted with cameras. However, automated methods are still lacking to accurately count individuals across entire surveys. Here, we leverage a tracking‐by‐detection framework to not only detect individuals but also link the resulting detections across ...

An integrated Structure-from-Motion and time-lapse technique for quantifying ice-margin dynamics

Journal of Glaciology, 2017
Fine resolution topographic data derived from methods such as Structure from Motion (SfM) and Multi-View Stereo (MVS) have the potential to provide detailed observations of geomorphological change, but have thus far been limited by the logistical ...

Assessing veterinary students’ attitudes towards pain in cattle before and after final‐year clinical training

Veterinary Record, EarlyView.
Abstract Background Cattle only show subtle signs of pain, making pain assessment difficult. The approach to pain and the use of analgesics depend on the treating person's experience and opinions. Methods Bavarian veterinary students were asked to answer two identical questionnaires before and after 12 weeks of clinical training in a ruminant clinic. A

Temporal and seasonal trends of bovine tuberculosis in the Irish cattle population (2008–2024)

Veterinary Record, EarlyView.
Abstract Background Bovine tuberculosis (bTB) has substantial impacts on the Irish cattle industry. Between 2016 and 2024, its burden increased in Irish cattle. As an initial step towards understanding drivers of this increase, we explore long‐term trends in measures of bTB burden and cattle demographics in Ireland. Methods Using data from 2008 to 2024,

Suitable habitat of Himalayan wolf in Upper Mustang, Annapurna Conservation Area, Nepal

Wildlife Biology, EarlyView.
Decades ago, the Himalayan wolf Canis lupus chanco, a genetically distinct sub‐species of the gray wolf Canis lupus, faced persecution by local communities in the Nepalese Himalayas. Recently, wolf populations have returned and recolonized, sparking concerns about conflicts over livestock depredation, and emphasizing the urgent need for comprehensive ...

EFFECT OF PRE-CALVING BCS ON POSTPARTUM BCS AND BODY WEIGHT CHANGE OF SAHIWAL CATTLE [PDF]

, 2019
A total of 18 Sahiwal cattle of 1st to 4th parity were selected for the study and distributed into three different groups based on their pre calving body condition score (BCS) (before 15 days of expected date of calving) namely G1 (2.50 - 3.00), G2 (3 ...
