A UAV‐based deep learning pipeline for intertidal macrobenthos monitoring: Behavioral and age classification in Tachypleus tridentatus

Remote Sensing in Ecology and Conservation, EarlyView.
The endangered tri‐spine horseshoe crab (Tachypleus tridentatus), a “living fossil” crucial to coastal ecology and biomedical research, is experiencing severe population declines. Effective conservation requires efficient monitoring, which traditional methods cannot deliver at scale. We develop an integrated UAV deep learning framework tailored to this

Assessing the utility of Hsp90 gene for inferring evolutionary relationships within the ciliate subclass Hypotricha (Protista, Ciliophora)

BMC Evolutionary Biology, 2020
Background Although phylogenomic analyses are increasingly used to reveal evolutionary relationships among ciliates, relatively few nuclear protein-coding gene markers have been tested for their suitability as candidates for inferring phylogenies within ...

Summer Ephemeroptera, Plecoptera, and Trichoptera (EPT) Species Richness and Community Structure in the Lower Illinois River Basin of Illinois [PDF]

, 2018
Ephemeroptera, Plecoptera, and Trichoptera (EPT) species richness is useful for monitoring stream health, but no published studies in Illinois quantitatively document EPT richness or assemblage structure. The objectives of this study were to characterize

Integrated Use of Oxidative Stress and Histological Biomarkers of T. tinca as Indicators of 17‐Alpha‐Ethynylestradiol Exposure

Environmental Toxicology, EarlyView.
ABSTRACT The potential adverse effects of 17‐alpha‐ethynylestradiol (50, 100, and 500 μg EE2/kg b.w., for 30 days) on tench (Tinca tinca) were evaluated by integrating biomarkers including physiological (hepato‐somatic index, spleen‐somatic index, and hematocrit), oxidative stress (catalase, glutathione peroxidase, and glutathione reductase activities;

Curbing the trade in pangolin scales in China by revealing the characteristics of the illegal trade network

Scientific Reports
Globally, pangolins are the most heavily trafficked mammals and China is one of the main destinations for their scales and meat. Conducting separate studies on the characteristics of the illegal trade in pangolin meat and in scales in China will provide ...

The use of biomonitoring equivalents for interpreting blood concentrations in population studies: a case for polychlorinated biphenyls

AIMS Environmental Science, 2015
A number of exposure guideline values for environmental contaminants are established by various agencies for risk assessment purposes. Biomonitoring equivalents are conversions of external guideline values to internal doses, against which biomonitoring ...

DNA metabarcoding reveals wolf dietary patterns in the northern Alps and Jura Mountains

Wildlife Biology, EarlyView.
Understanding predator–prey interactions is crucial for wildlife management and human–wildlife coexistence, particularly in multi‐use landscapes such as western Europe. As wolves Canis lupus recolonize their former habitats, knowledge of their diet is essential for conservation, management and public acceptance.

Airborne DNA and Spider Webs Outperform Other eDNA Sources for Monitoring Terrestrial Vertebrates

Molecular Ecology Resources, EarlyView.
ABSTRACT Understanding the strengths and limitations of different environmental DNA substrates is essential for optimising terrestrial vertebrate surveys and monitoring. However, the performance of newly explored substrates (airborne eDNA, vegetation swabs, spiderwebs) compared to longstanding eDNA sources (water and soil) is uncertain.
