Predation Pressure of Invasive Marsh Frogs: A Threat to Native Amphibians?

open access: yesDiversity, 2021
Anurans have been introduced in many parts of the world and have often become invasive over large geographic areas. Although predation is involved in the declines of invaded amphibian populations, there is a lack of quantitative assessments evaluating ...

The detection of Mycoplasma sturni and Mycoplasma moatsii from the choana of a barn swallow (Hirundo rustica): a case report

open access: yesBMC Veterinary Research, 2023
Background Mycoplasmas are found in many different species. Until now 26 avian mycoplasma species have been described, but in the most free ranging bird species the prevalence and significance of Mycoplasma spp. is still unclear. Case presentation In May

Factors Influencing Vertical Transmission of Psittacine Bornavirus in Cockatiels (Nymphicus hollandicus)

open access: yesViruses, 2022
The transmission of parrot bornavirus is still not fully understood. Although horizontal transmission through wounds can be one route, vertical transmission is still discussed.

Amphibians [PDF]

open access: yesCurrent Biology, 2018
Since the dawn of history, amphibians have been a part of human culture. Western Europeans built fires for cooking and warmth, adding large logs as needed. What occasionally emerged was astounding: large black animals (which had found shelter in the logs) with four legs and a tail, jet black with striking bright yellow spots.

Experimental Infection of Embryonic Cells and Embryonated Eggs of Cockatiels (Nymphicus hollandicus) with Two Parrot Bornavirus Isolates (PaBV-4 and PaBV-2)

open access: yesViruses, 2022
Parrot bornavirus (PaBV) might be transmitted vertically. Cockatiel embryonic brain cells and embryonated eggs of cockatiels (ECE) were infected with PaBV-2 and PaBV-4.

Stress Assessment of Wild Boar (Sus scrofa) in Corral-Style Traps Using Serum Cortisol Levels

open access: yesAnimals, 2022
Capture of wild boar in corral-style traps with subsequent culling is increasingly used for population management. The method is debated due to animal welfare concerns making welfare studies in traps necessary. While previous studies focused on behaviour

Empirical Evidence for the Rescue Effect from a Natural Microcosm

open access: yesAnimals, 2023
Ecological theory predicts that populations which receive immigrants are less vulnerable to extinction than those that do not receive immigrants (the “rescue effect”). A parallel but opposite process may also exist, where emigration increases the risk of

Potential Distribution of Amphibians with Different Habitat Characteristics in Response to Climate Change in South Korea

open access: yesAnimals, 2021
Amphibian species are highly vulnerable to climate change with significant species decline and extinction predicted worldwide. However, there are very limited studies on amphibians in South Korea. Here, we assessed the potential impacts of climate change
