Investigation of Commensal Escherichia coli Populations of Cormorant Hatchlings in the Absence of Anthropogenic Impacts in Remote Areas of West Mongolia

Microorganisms, 2021
To increase our understanding of bacterial intestinal colonization in animal populations lacking substantial anthropogenic influence we studied the diversity of E. coli in cormorants from the pristine West-Mongolian steppe. E.

Little penguins select more isolated nest boxes for breeding, but lay date influences breeding success

The Journal of Wildlife Management, EarlyView.
We determined that more isolated and possibly older nest boxes were selected by little penguins for breeding at Pōhatu/Flea Bay, New Zealand. However, breeding success was influenced by lay date in comparison to nest box characteristics. These findings inform immediate conservation recommendations regarding nest box design and placement.

What turns us off about green and blue spaces in cities? Understanding perceived problems and unpleasant experiences for more just urban planning, design and management

People and Nature, EarlyView.
Abstract The planning, design and management of urban green and blue spaces necessitate trade‐offs between these spaces' many benefits and their drawbacks, but knowledge of perceived problems and unpleasant experiences in urban green and blue spaces remains limited.

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

Remote 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

Effects of researcher disturbance on Double-crested Cormorant nest survival

Journal of Field Ornithology
Demographic data on avian species are critically important for conservation and management. Research on avian demography often requires some level of human disturbance at nest sites.

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

Journal 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.

Northern range shift may be due to increased competition induced by protection of species rather than to climate change alone

Ecology and Evolution, 2018
Few long‐term, large‐scale studies have been conducted about the factors likely to explain changes in species abundance and distribution in winter. Range shifts are generally attributed to the climate change or land use.

Shifting Effects of Ocean Conditions on Survival and Breeding Probability of a Long-Lived Seabird. [PDF]

PLoS ONE, 2015
With a rapidly changing climate, there is an increasing need to predict how species will respond to changes in the physical environment. One approach is to use historic data to estimate the past influence of environmental variation on important ...

Steep declines of colonial wading birds in northeastern North America's largest breeding population

Conservation Science and Practice, EarlyView.
This study analyzed 22 years of complete nest census data for colonial wading birds in New York–New Jersey Harbor, the largest breeding population in the northeastern United States. Over this period, the total wading bird population decreased by 27%, a rate exceeding average long‐term declines across North American birds.

Diet of the Neotropical Cormorant (Phalacrocorax brasilianus) in a Patagonian Freshwater Environment Invaded by Exotic Fish [PDF]

, 2012
The diet of the Neotropical Cormorant (Phalacrocorax brasilianus) was evaluated in the Limay River basin, a freshwater system invaded by exotic salmonids. Analyses of 106 pellets showed that fish were the most important prey (79.9% by numerical frequency
