The last few years have seen a surge of interest from field ecologists and evolutionary biologists to study neoplasia and cancer in wildlife. This contributes to the One Health Approach, which investigates health issues at the intersection of people, wild and domestic animals, together with their changing environments. Nonetheless, the emerging field of wildlife cancer is currently constrained by methodological limitations in detecting cancer using non-invasive sampling.

- Researchers created a new molecular method using Loop-mediated Isothermal Amplification (LAMP) to determine the sex of marine bivalves that exhibit doubly uniparental inheritance (DUI) of mitochondria, where both males and females transmit their mitochondria but with distinct types.
- They tested this method on 154 bivalve samples from the Atlantic coast of France, confirming that LAMP results matched those from traditional methods like PCR and microscopic examination of gonads.
- The study suggests that using LAMP can enhance eco-evolutionary research on DUI by exploring genetic factors like sexual selection and dispersal patterns in marine species.
Article Synopsis
- Scallops exhibit significant variability in their mitochondrial genomes, with structural and compositional differences even among closely related species, particularly within the Chlamydinae group.
- The study sequenced the mitochondrial genome of Mimachlamys varia, revealing a unique gene arrangement and highlighting issues with the existing taxonomic classification of the Mimachlamys genus.
- Findings indicate discrepancies between phylogenetic analyses based on mitochondrial protein-coding and rRNA genes, suggesting that better taxon sampling is necessary to fully understand the mechanisms behind the varied mitochondrial genome structures in scallops.
Seminatural habitats are declining throughout the world; thus, the role of small anthropogenic habitats in the preservation of plants is becoming increasingly appreciated. Here, we surveyed the orchid flora of roadside verges in five Central European countries (Austria, Hungary, Romania, Slovakia, and Slovenia) and tested how the surrounding landscape matrix affects the overall number of species and individuals, and also different functional groups of orchids. We found more than 2,000 individuals of 27 orchid species during our surveys.

It is listed as "endangered" on the IUCN Red List of Threatened Species. Microsatellite markers can contribute to conservation efforts by allowing the study of the genetic structure of its shrinking populations.

Methods And Results: We utilized a 454 pyrosequencing approach to identify simple sequence repeat (SSR) regions in a microsatellite-enriched library.
The legacy and reach of anthropogenic influence is most clearly evidenced by its impact on the most remote and inaccessible habitats on Earth. Here we identify extraordinary levels of persistent organic pollutants in the endemic amphipod fauna from two of the deepest ocean trenches (>10,000 metres). Contaminant levels were considerably higher than documented for nearby regions of heavy industrialization, indicating bioaccumulation of anthropogenic contamination and inferring that these pollutants are pervasive across the world's oceans and to full ocean depth.
