APPLICATION OF THE GREAT CORMORANT'S (Phalacrocorax carbo sinensis) DAILY MEAL IN THE STIMATION OF DAMAGES AT FISHPONDS [PDF]

open access: yesCroatian Journal of Fisheries, 2004
Daily meal of the Great Cormorant (Phalacrocorax carbo sinensis), joined with the number of birds and composition of fish in the meal, has high importance in total calculation of damage-costs on fish stock.

Seasonal variations in numbers of great cormorant (Phalacrocorax carbo) on the Kolut fish farm (nw Serbia) [PDF]

open access: yesArchives of Biological Sciences, 2006
Seasonal variations in numbers of great cormorant were studied between 1998 and 2004 on ponds of the Kolut fish farm (NW Serbia). Its presence is not detected only during winter. Spring migration culminates in early March.

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

open access: yesMicroorganisms, 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.

Variability of clutch size in Cormorant (Phalacrocorax carbo sinensis) at the Jeziorsko Reservoir (Central Poland) in 2004 [PDF]

open access: yes, 2008
The analysis of the clutch size variability in Cormorant (P. carbo sinensis) was based on study results in colony at the “Jeziorsko Reservoir” (central Poland) in 2004. There were used 328 broods controlled 3-5 times in the season.

Primeiro estudo parasitológico em rã com garras Africano (Xenopus laevis, Anfibia) no Chile [PDF]

open access: yes, 2017
Introduced species can arrive into new territories with parasites; however, these species are expected to face lower parasite richness than in their original regions. Both introduced hosts and parasites can affect native fauna.

Comparing Transcriptomic Responses to Chemicals Across Six Species Using the EcoToxChip RNASeq Database

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract The EcoToxChip project includes RNA‐sequencing data from experiments involving model (Japanese quail, fathead minnow, African clawed frog) and ecological (double‐crested cormorant, rainbow trout, northern leopard frog) species at multiple life stages (whole embryo and adult) exposed to eight chemicals of environmental concern known to perturb ...

Neo‐Taphonomic Analysis of Prey Bone Remains Accumulated by Golden Eagle (Aquila chrysaetos): A Case of Nests in Southern France

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The golden eagle (Aquila chrysaetos) nests in rock cavities where it accumulates prey bone remains during the breeding season. Because nests can be reoccupied from year to year, these faunal elements can form remarkable bone accumulations and, in the sub‐fossil record, be mixed with assemblages derived from human or other predator activities ...

Reconstructing Early Human Subsistence in Near Oceania: New Insights From Matenkupkum and Matenbek

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The colonization of New Ireland ~44–40,000 years ago represents the earliest evidence of human occupation in Near Oceania. Yet, the precise impacts of climatic changes on subsistence strategies during the Late Pleistocene, Last Glacial Maximum, and Holocene remain poorly understood.

Effects of researcher disturbance on Double-crested Cormorant nest survival

open access: yesJournal 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.

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

open access: yesPLoS 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 ...
