Potential contribution of alpha‐fetoprotein level to biomarker of pregnancy outcome in Asian elephants

open access: yesVeterinary Medicine and Science
Alpha‐fetoprotein (AFP) is a structural serum glycoprotein that plays vital roles in reproduction and mammalian development. Analysis of serum prolactin (PRL) is considered one of the useful methods for diagnosing pregnancy in Asian elephants.

Survival of a potential bacterial biocontrol agent in the soil and its impact on microbial communities

open access: yesPest Management Science, EarlyView.
In soil microcosms, the candidate Bacillus persisted ≥6 months and caused modest community shifts whose transience and magnitude were soil dependent. Abstract BACKGROUND Sclerotinia sclerotiorum is a major crop pathogen commonly managed using fungicides.

Resilient Flow Regimes in the Rio Grande—Río Bravo Basin

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Water is essential for human development and is an indispensable resource for economic activity and a country's growth. However, current water practices, along with increasing land‐use change, climate change, and agricultural practices, have significantly altered the hydrological cycle and water availability.

Deep learning‐based ecological analysis of camera trap images is impacted by training data quality and quantity

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Machine learning image classifiers are increasingly being used to automate camera trap image labelling, but we don't know how much ML model accuracy matters for downstream ecological analyses. Using two large data sets from an African savannah and an Asian dry forest ecosystem, we compared human labelled data with predictions from deep‐learning models ...

Semi‐automated seal detection on the Western Antarctic Peninsula: an unsupervised machine learning approach for detecting ice seals in aerial survey data

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study presents a semi‐automated, rule‐based image analysis pipeline to detect ice seals in aerial surveys of the Western Antarctic Peninsula during an unusually low sea ice year. By using simple hierarchical clustering instead of deep learning, the method substantially reduced human annotation effort while achieving 82% recall, identifying 758 ...

An autonomous network of acoustic detectors to map tiger risk by eavesdropping on prey alarm calls

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Tiger population recovery brings with it increased fatalities from human‐tiger conflict. We describe a network of autonomous intelligent passive acoustic sensors that monitor the forest for deer alarm calls as a proxy for tiger risk and provide a risk map to local communities in real‐time.

Retrospective image analysis for long‐term demography using Google Earth imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...
