Evidence for coal forest refugia in the seasonally dry Pennsylvanian tropical lowlands of the Illinois Basin, USA [PDF]

open access: yes, 2014
The Moscovian plant macroflora at Cottage Grove southeastern Illinois, USA, is a key example of Pennsylvanian (323–299 Million years ago) dryland vegetation.

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', unexposed to treatment.

Indicators of ecological change: an inter-site comparison of a concurrent monitoring of wildlife occurrence and hunting activity in central Africa [PDF]

open access: yes, 2015
Choosing and adapting wildlife management options ideally requires appropriate and affordable information on trends in animal populations and offtakes over several years. In African tropical forests, most studies have been documenting separately wildlife

Hydrologic refugia, plants, and climate change

open access: yesGlobal Change Biology, 2017
AbstractClimate, physical landscapes, and biota interact to generate heterogeneous hydrologic conditions in space and over time, which are reflected in spatial patterns of species distributions. As these species distributions respond to rapid climate change, microrefugia may support local species persistence in the face of deteriorating climatic ...

Still standing: Recent patterns of post-fire conifer refugia in ponderosa pine-dominated forests of the Colorado Front Range.

open access: yesPLoS ONE, 2020
Forested fire refugia (trees that survive fires) are important disturbance legacies that provide seed sources for post-fire regeneration. Conifer regeneration has been limited following some recent western fires, particularly in ponderosa pine (Pinus ...

On-farm trials with rice fish cultivation in the west Kano rice irrigation scheme, Kenya [PDF]

open access: yes, 2006
The viability of integrating rice farming with fish culture was studied in ten (10) rice plots. The on-farm research was done during one rice-growing season starting May 2003.

Pattern of population structuring between Belgian and Estonian bumblebees [PDF]

open access: yes, 2019
Several population genetic studies investigated the extent of gene flow and population connectivity in bumblebees. In general, no restriction in gene flow is considered for mainland populations of common bumblebee species.

Seaweed farms provide refugia from ocean acidification

open access: yesScience of The Total Environment, 2021
Seaweed farming has been proposed as a strategy for adaptation to ocean acidification, but evidence is largely lacking. Changes of pH and carbon system parameters in surface waters of three seaweed farms along a latitudinal range in China were compared, on the weeks preceding harvesting, with those of the surrounding seawaters.

Identifying climate‐change refugia for species management and conservation in the Pacific Northwest

open access: yesConservation Science and Practice
The impacts of climate change are already affecting many species and habitats, presenting challenges for species management and conservation. Protecting climate refugia—areas buffered from climate shifts where species can persist despite broader changes ...
