Camera Traps: A Novel Method to Estimate Numbers of Nesting Sea Turtles

Ecology and Evolution
Abundance estimates are difficult to obtain for many animal groups, yet essential for endangered species management and conservation. For sea turtles, estimates are made from ground counts of nesting females, tracks, and nests, but these are challenging ...

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

Molecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

Assessing Applicability of eDNA‐Based Sampling for Population Monitoring of Leatherback Turtles in the Northeast Indian Ocean

Environmental DNA
Current population genetics studies of sea turtles primarily rely on invasive tissue sampling or blood draws, which involve the capture and handling of the animals that require specific permits and resources.

Advancing Semiochemical Tools for Mountain Pine Beetle Management: Dendroctonus ponderosae Responses to Saprophytic Fungal Volatiles

Metabolites
Background/Objectives: Within their host trees, mountain pine beetles (MPBs, Dendroctonus ponderosae) interact with many fungal species, each releasing a unique profile of volatile organic compounds (VOCs). The FVOCs released by the two primary symbionts

Preoperative circulating tumor cells integrated with imaging analysis for prognostic evaluation in head and neck squamous cell carcinoma

Molecular Oncology, EarlyView.
Detecting circulating tumor cells (CTCs) in blood before surgery may help predict outcomes in patients with head and neck squamous cell carcinoma (HNSCC). Here, we show when combined with tumor size and lymph node involvement from routine imaging, CTC status identifies high‐risk patients with poorer survival—offering a simple, minimally invasive tool ...
