A Multi-Taxa Approach to Estuarine Biomonitoring: Assessing Vertebrate Biodiversity and Ecological Continuity Using Environmental DNA Metabarcoding in the Rance River (Brittany, France). [PDF]
Ecol EvolWe applied eDNA metabarcoding to assess vertebrate diversity in the Rance Estuary, France, across five stations spanning marine to freshwater environments, including areas upstream and downstream of a tidal power plant dam. A total of 124 vertebrate MOTUs were detected, with community composition reflecting the estuarine gradient and species turnover ...

The energetic cost of mounting an immune response for Pallas’s long-tongued bat (Glossophaga soricina) [PDF]
PeerJ, 2018 The acute phase response (APR) is the first line of defense of the vertebrate immune system against pathogens. Mounting an immune response is believed to be energetically costly but direct measures of metabolic rate during immune challenges contradict ...
