Refugia and anthelmintic resistance: Concepts and challenges [PDF]

open access: yesInternational Journal for Parasitology: Drugs and Drug Resistance, 2019
Anthelmintic resistance is a threat to global food security. In order to alleviate the selection pressure for resistance and maintain drug efficacy, management strategies increasingly aim to preserve a proportion of the parasite population in ‘refugia ...

The fate of endemic insects of the Andean region under the effect of global warming. [PDF]

open access: yesPLoS ONE, 2017
Three independent but complementary lines of research have provided evidence for the recognition of refugia: paleontology, phylogeography and species distributional modelling (SDM). SDM assesses the ecological requirements of a species based on its known

Video surveys of sea snakes in the mesophotic zone shed light on trends in populations

open access: yesFrontiers in Marine Science, 2022
Declines in abundance of sea snakes have been observed on reefs throughout the Indo-Pacific, although the reasons are unknown. To date, surveys have occurred on shallow reefs, despite sea snakes occurring over a large depth range.

Large-scale effects of turbidity on coral bleaching in the Hawaiian islands

open access: yesFrontiers in Marine Science, 2022
Turbidity from land-based runoff has been identified as a possible driver of coral bleaching refugia, as particulate matter in turbid habitats may block excessive irradiance and alter the food supply to corals during ocean heatwaves.

Climatic Refugia and Geographical Isolation Contribute to the Speciation and Genetic Divergence in Himalayan-Hengduan Tree Peonies (Paeonia delavayi and Paeonia ludlowii)

open access: yesFrontiers in Genetics, 2021
Himalaya and Hengduan Mountains (HHM) is a biodiversity hotspot, and very rich in endemic species. Previous phylogeographical studies proposed different hypotheses (vicariance and climate-driven speciation) in explaining diversification and the observed ...

Basaltic Outcrops as Centers of Diversity for Xerothermic Plants in the Sudetes Mountains (Central Europe)

open access: yesDiversity, 2021
Rock outcrops have promoted a high level of species diversity and provided a stable microclimate for long time periods. The present study is devoted to plant diversity of natural Quaternary outcrops of basaltic rocks.

The ecological health of Lake Victoria (Kenya) in the face of growing cage aquaculture

open access: yesConservation Science and Practice, 2022
The rapid growth of cage aquaculture of introduced Nile tilapia (Oreochromis niloticus) in Lake Victoria has raised urgent environmental concerns. This study aims to compare local environmental conditions, fish species abundance and diversity between ...

Neotropical refugia

open access: yesThe Holocene, 2012
Patterns of endemism in the Neotropics have been explained by restriction of forest to ‘refugia’ in arid cold-stages of the Quaternary (Haffer J (1969) Speciation in Amazonian forest birds. Science 165: 131–137). The palaeoecological record, however, shows no such forest contraction.
