Migratory Birds as Global Dispersal Vectors [PDF]

open access: yesTrends in Ecology & Evolution, 2016
Propagule dispersal beyond local scales has been considered rare and unpredictable. However, for many plants, invertebrates, and microbes dispersed by birds, long-distance dispersal (LDD) might be regularly achieved when mediated by migratory movements.

Genetic patterns reveal differences between the invasion processes of common ragweed in urban and non-urban ecosystems

open access: yesGlobal Ecology and Conservation, 2022
Invasive alien plant species (IAPS) in urban ecosystems can significantly impact ecosystems and human wellbeing. However, our knowledge on the IAPS in urban ecosystems are limited due to the small number of studies. In this study, we examined features of

Leptin administration does not influence migratory behaviour in white-throated sparrows (Zonotrichia albicollis) [PDF]

open access: yesPeerJ, 2022
Migratory flights by birds are among the most energetically demanding forms of animal movement, and are primarily fueled by fat as an energy source. Leptin is a critical fat-regulation hormone associated with energy balance in non-avian species but its ...

Human infections associated with wild birds. [PDF]

open access: yes, 2008
IntroductionWild birds and especially migratory species can become long-distance vectors for a wide range of microorganisms. The objective of the current paper is to summarize available literature on pathogens causing human disease that have been ...

Migratory birds, ticks, andBartonella [PDF]

open access: yesInfection Ecology & Epidemiology, 2011
Bartonella spp. infections are considered to be vector-borne zoonoses; ticks are suspected vectors of bartonellae. Migratory birds can disperse ticks infected with zoonotic pathogens such as Rickettsia and tick-borne encephalitis virus and possibly also Bartonella.

The Hwaseong Wetlands Reclamation Area and Tidal Flats, Republic of Korea: A Case of Waterbird Conservation in the Yellow Sea

open access: yesConservation, 2022
The reclamation of tidal flats is implicated in the declines of a large number of migratory waterbird species along the East Asia-Australasian Flyway, and has resulted in the assessment of Yellow Sea tidal flats as an Endangered habitat by the IUCN ...

Research topics and trends of endangered species using text mining in Korea

open access: yesJournal of Asia-Pacific Biodiversity, 2020
Continuous development due to human activities has extinctionized many floral and faunal species on earth and seriously threatened the ecosystem. Many countries are working hard to protect and restore endangered species by conducting a range of studies ...

Tracking the historical urban development by classifying Landsat MSS data with training samples migrated across time and space

open access: yesInternational Journal of Digital Earth, 2023
To reveal the historical urban development in large areas using satellite data such as Landsat MSS still need to overcome many challenges. One of them is the need for high-quality training samples.

Light-dependent magnetoreception in birds : increasing intensity of monochromatic light changes the nature of the response [PDF]

open access: yes, 2007
Background The Radical Pair model proposes that magnetoreception is a light-dependent process. Under low monochromatic light from the short-wavelength part of the visual spectrum, migratory birds show orientation in their migratory direction.
