Stopover refueling, movement, and departure decisions in the White-throated Sparrow: the influence of intrinsic and extrinsic factors during spring migration.

Journal of Animal Ecology, 2020
1. Differential migration timing between sex or age classes are examples of how migratory movement strategies can differ among sub-groups within a population.

Multi‐Seasonal eDNA Metabarcoding Highlights a Resurgence in Fish Diversity Across a Severely Impacted Estuarine Ecosystem

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Aquatic ecosystems have been in an alarming state of decline for decades. In particular, estuarine ecosystems have experienced long‐term declines in fish diversity due to factors such as habitat degradation, pollution and altered hydrology. Monitoring these systems is often limited by the difficulty and cost of conventional survey methods.

Spatial Segregation and Trophic Niche Divergence in Two Disjunct Populations of Wedge‐Tailed Shearwater Ardenna pacifica in Eastern Australia

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study investigated habitat use and trophic niche differentiation in two wedge‐tailed shearwater populations in eastern Australia (2015 to 2019). Temperate birds foraged mainly in southeastern Australian waters and undertook a pre‐staging detour towards the subtropical frontal zone before migration, whereas subtropical birds foraged further east ...

Automated telemetry reveals migratory movements and stopover timing of an endangered saltmarsh passerine

Avian Conservation and Ecology
Historically, the fates of individual passerines during migration have been informed primarily by scarce data on band recaptures and resighting. This constraint is particularly problematic for imperiled passerines because information on the timing and ...

Biofilm consumption and variable diet composition of western sandpipers (Calidris mauri) during migratory stopover.

PLoS ONE, 2015
Many shorebird species undertake long-distance migrations punctuated by brief stays at food-rich, estuarine stopover locations. Understanding use of these food resources helps guide conservation and responsible development decisions.

Wide ranging stopover movements and substantial fuelling in first year garden warblers at a northern stopover site

Journal of Avian Biology, 2014
Migratory birds use stopovers to replenish their fuel reserves and they generally spend more time at stopover sites than they do in actual flight. When arriving at a new stopover site birds may need to search extensively to find a suitable feeding area and this search and settling period may affect the duration of stopover ...

A Multi‐Taxa Approach to Estuarine Biomonitoring: Assessing Vertebrate Biodiversity and Ecological Continuity Using Environmental DNA Metabarcoding in the Rance River (Brittany, France)

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We 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 ...
