Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.

The importance of voucher specimens: misidentification or previously unknown mtDNA diversity in Phalacrocorax capillatus (Aves: Phalacrocoracidae)?

open access: yesMitochondrial DNA. Part B. Resources, 2023
A recently published complete mitochondrial genome of Japanese or Temminck’s cormorant (Phalacrocorax capillatus) was the first of this species (GenBank accession number LC714913).

Big Bird: A global dataset of birds in drone imagery annotated to species level

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Predator telemetry informs temporal and spatial overlap with stocked salmonids in Lake Huron

open access: yesAnimal Biotelemetry, 2023
Double-Crested Cormorants (Phalacrocorax auratus), Walleyes (Sander vitreus), and Lake Trout (Salvelinus namaycush) are migratory predators that undergo extensive movements in Lake Huron. Stocking of juvenile salmonid fish (Oncorhynchus and Salmo sp.) is

Offshore wind farm avoidance by a discard‐feeding seabird is independent of local fishing activity

open access: yesJournal of Animal Ecology, EarlyView.
Fishing is not allowed within wind farms; therefore, discard‐feeding seabirds may appear to avoid wind farm areas. We found that most Lesser Black‐backed Gulls avoided the wind farm area, but not each individual in each period. Avoidance of the wind farm was not driven by fishing exclusion within its perimeter.

Waterbird zoogeochemical effects shape wetland nutrient dynamics and algal communities in Laurentian Great Lakes coastal freshwater wetlands

open access: yesJournal of Animal Ecology, EarlyView.
Distinct waterbird species influence nutrient cycling through guano contributions in Great Lakes coastal wetlands. Waterbird‐derived nutrients favour distinct algal communities and wetland sediments rapidly remove waterbird nutrients via biogeochemical processes.

Geographical distribution of the Pinnated Bittern (Botaurus pinnatus): Update and seasonal movement pattern

open access: yesIbis, EarlyView.
The Pinnated Bittern Botaurus pinnatus (Ardeidae) is a widely distributed Neotropical wading bird whose distribution and seasonal status remain poorly resolved. Discrepancies among published literature, citizen science records and the range currently assumed by BirdLife International indicate that both its geographical distribution and migratory ...

Great cormorants (Phalacrocorax carbo) as potential vectors for the dispersal of Vibrio cholerae

open access: yesScientific Reports, 2017
Vibrio cholerae is the cause of cholera, a devastating epidemic and pandemic disease. Despite its importance, the way of its global dissemination is unknown. V.
