Impact of land-use changes on ant communities and the retention of ecosystem services in Rashad District, Southern Kordofan, Sudan

South African Journal of Science, 2022
The ecological consequences of biodiversity loss are usually the reduction of ecosystem functions. These responses, however, differ depending on the type of land-use change and the ecological setting.

Determinants of species richness in the Park Grass experiment [PDF]

, 2005
The Park Grass Experiment at Rothamsted in southeast England was started in 1856, making it the longest-running experiment in plant ecology anywhere in the world.

Effects of Eucalyptus tree plantations on soil seed bank and soil physicochemical properties of Qimbaba forest

Cogent Food & Agriculture, 2019
Qimbaba, a prioritized forest area in the northwest of Ethiopia. However, it is experiencing deforestation that limits restoration possibilities. Hence, a detailed assessment of soil seed bank composition and regeneration potential could permit to ...

Steady turnover in a bird community in a periurban landscape in Northern Italy: a look at the change in species richness over time

Rivista Italiana di Ornitologia - Research in Ornithology, 2022
From November 2017 until February 2022, with a partial interruption during 2020 linked to the COVID 19 pandemic, the bird community was monitored in a 30 hectares periurban plot in north-western Lombardy, in the province of Varese.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

What does ‘lexical richness’ tell us about an L2 learner’s vocabulary knowledge? [PDF]

, 2020
The relationship between lexical richness and vocabulary knowledge remains actively between lexical richness and second language learners’ vocabulary knowledge. I review definitions and make a case for what lexical richness can and cannot tell us about a

Turnover of benthic macroinvertebrates along the Mthatha River, Eastern Cape, South Africa: implications for water quality bio-monitoring using indicator species

Journal of Freshwater Ecology, 2018
The ecological integrity of the Mthatha River is increasingly under threat from climate change and anthropogenic impacts of contamination by acidification, organic pollutants, industrial and agricultural chemicals, and waste water.

Environmental and Human Controls of Ecosystem Functional Diversity in Temperate South America

Remote Sensing, 2013
The regional controls of biodiversity patterns have been traditionally evaluated using structural and compositional components at the species level, but evaluation of the functional component at the ecosystem level is still scarce.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A standardised sampling protocol for robust assessment of reach-scale fish community diversity in wadeable New Zealand streams [PDF]

, 2010
The New Zealand fish fauna contains species that are affected not only by river system connectivity, but also by catchment and local-scale changes in landcover, water quality and habitat quality.
