Exploring mark-resighting-recovery models to study savannah tree demographics [PDF]

Animal Biodiversity and Conservation, 2004
Despite their sessile nature, juvenile trees in savannah ecosystems are not always easy to encounter. Here, the remedy of choice in animal studies, capture-recapture modelling, is evaluated with respect to plants.

Efficient and Accurate Spatio‐Temporal Population Monitoring of Mobile Animals Using Drones and Computer Vision

Remote Sensing in Ecology and Conservation, EarlyView.
Drones and computer vision offer an efficient way to estimate animal populations over localized areas, but surveys often require stitching many overlapping images together. If animals move during the survey, traditional orthomosaic‐based counting methods become unreliable, with some animals appearing in multiple locations while others appear not at all,

Few Annotations, High Accuracy: Transfer Learning and Data Augmentation Improve Passive Acoustic Monitoring of the Vulnerable African Manatee

Remote Sensing in Ecology and Conservation, EarlyView.
Can deep learning reliably detect a threatened species in passive acoustic monitoring with few annotations? Across 52 sites and 600 recording days, we compared two deep learning recognizers with the traditional machine learning Kaleidoscope for detecting African manatee vocalizations.

A comparison of abundance estimators for small mammal populations

Zoologia (Curitiba), 2013
A major difficulty in the application of probabilistic models to estimations of mammal abundance is obtaining a data set that meets all of the assumptions of the model.

Who Can Afford to Fail? Investigating Science Students' Perceptions of Failure Through the Lens of Their Identities

Science Education, EarlyView.
ABSTRACT Scientists agree that learning to cope with failures is an important skill for science students to develop, and students who participate in science research often have positive outcomes after coping with science failures. However, the experience of failure in undergraduate science education more broadly seems to have an overall negative impact

Population dynamics of Gracilinanus agilis (Didelphidae) during a period of extreme drought in a Caatinga Biome Fragment

Cadernos Cajuína
Precipitation has been identified as a key driver of the population dynamics of small mammals in seasonal environments, particularly in semiarid regions.

Cooperative Regulation of Defect‐Mediated Molecular Recognition With Single‐Walled Carbon Nanotubes

Small, EarlyView.
Defect‐mediated sensing in SWCNTs arises from the cooperative interplay of defect characteristics, density, heterogeneity, analyte properties, corona composition, and environment. Understanding these interconnected variables enables tunable fluorescence modulation, selective molecular recognition, ratiometric sensing, and sensitive detection in complex
