Genetic effects of long-term captive breeding on the endangered pygmy hog [PDF]

PeerJ, 2021
Long-term captive populations often accumulate genetic changes that are detrimental to their survival in the wild. Periodic genetic evaluation of captive populations is thus necessary to identify deleterious changes and minimize their impact through ...

Plant rarity in fire-prone dry sclerophyll communities

Scientific Reports, 2022
Understanding the responses of rare species to altered fire disturbance regimes is an ongoing challenge for ecologists. We asked: are there associations between fire regimes and plant rarity across different vegetation communities?

Feral cats use fine scale prey cues and microhabitat patches of dense vegetation when hunting prey in arid Australia

Global Ecology and Conservation, 2022
Introduced predators are one of the leading causes of decline in island vertebrates. Understanding how they hunt and kill threatened prey can help improve management activities.

Protected Areas and Endemic Freshwater Fishes of the Cape Fold Ecoregion: Missing the Boat for Fish Conservation?

Frontiers in Environmental Science, 2020
Freshwater systems and their associated biodiversity are among the most threatened ecosystems globally. The greatest threats to freshwater fishes are the introduction and spread of non-native species, pollution, habitat degradation and loss, and ...

Island characteristics and sampling methodologies influence the use of stable isotopes as an ecosystem function assessment tool

Ecological Solutions and Evidence, 2021
Monitoring seabird‐derived nutrients on islands following invasive mammal eradications may provide a useful, cost‐ and time‐efficient indication of the recovery of ecosystem function; however, the technique has only been investigated on environmentally ...

Taxonomic research priorities for the conservation of the South African flora

South African Journal of Science, 2013
Taxonomic revisions, monographs and floras are the most important, and often the only source of data for assessing the extinction risk of plants, with recent revisions contributing to more accurate assessments.

Assessing Risks to Wildlife from Free-Roaming Hybrid Cats: The Proposed Introduction of Pet Savannah Cats to Australia as a Case Study

Animals, 2019
Hybrid cats—created by crossing different species within the family Felidae—are popular pets, but they could potentially threaten native species if they escape and establish free-roaming populations.

Far eastern curlew and whimbrel prefer flying low - wind support and good visibility appear only secondary factors in determining migratory flight altitude

Movement Ecology, 2021
Background In-flight conditions are hypothesized to influence the timing and success of long-distance migration. Wind assistance and thermal uplift are thought to reduce the energetic costs of flight, humidity, air pressure and temperature may affect the

Spatial diversity and habitat characteristics of seagrass meadows with management recommendations in the Andaman and Nicobar Islands, India

Frontiers in Marine Science, 2023
The Andaman and Nicobar Islands, India, a geographically remote region, harbor a diverse island ecosystem. Limited exploration has hindered our understanding of marine floral biodiversity in this area.
