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 ...

On microrefugia and cryptic refugia [PDF]

open access: yesJournal of Biogeography, 2010
AbstractThe existence of microrefugia and/or cryptic refugia has been proposed to explain the colonization patterns of temperate continents after the Last Glacial Maximum, as well as to gain an understanding of the present genetic structure of species and their populations.

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

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

Fire refugia are robust across Western US forested ecoregions, 1986–2021

open access: yesEnvironmental Research Letters, 2023
In the Western US, area burned and fire size have increased due to the influences of climate change, long-term fire suppression leading to higher fuel loads, and increased ignitions.

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.
