Comparison of bird assemblage structures and diversity patterns between seasons among two Ethiopian wetlands

open access: yesBMC Zoology, 2023
Wetlands are significant habitats for bird populations, and knowledge of the diversity and other ecological aspects of bird species contribute to the management of the ecosystem.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Conservation of animal–plant mutualistic networks is essential to prevent functional extinction of the narrow endemic morning glory Ipomoea cavalcantei in Amazon canga ecosystems

open access: yesFrontiers in Ecology and Evolution
Current studies of animal–plant mutualistic interaction networks and species climate change resilience call for redesigning biodiversity conservation management toward preventing species coextinction cascades and using interspecific hybridization as a ...

Wallum on the Nabiac Pleistocene barriers, lower North Coast of New South Wales [PDF]

open access: yes, 2013
Wallum is widespread on coastal dunefields, beach ridge plains and associated sandy flats in northern NSW and southern Queensland. These sand masses contain large aquifers, and the wallum ecosystem is considered to be generally groundwater-dependent ...

Analysis of a conserved cellulase transcriptional regulator reveals inducer-independent production of cellulolytic enzymes in Neurospora crassa. [PDF]

open access: yes, 2013
Cellulose is recalcitrant to deconstruction to glucose for use in fermentation strategies for biofuels and chemicals derived from lignocellulose. In Neurospora crassa, the transcriptional regulator, CLR-2, is required for cellulolytic gene expression and

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Study of endophytic fungi of Ipomoea pes-caprae reveals the superiority of in situ plant conservation over ex situ conservation from a mycological view

open access: yesScientific Reports
In nature conservation, ex situ and in situ conservation strategies are discussed for protecting endangered species of plants and animals. However, the impacts of these strategies on the microbes associated with these species are rarely considered.

Development and application of a new Forestation Index: global forestation patterns and drivers [PDF]

open access: yes, 2013
Deforestation has long been heavily studied; several proximate and underlying causes behind the global decrease of forest extent have been discussed. However, systematic analyses of positive examples are sparse, even if forestation is happening in almost

Evolving Charge Correlations in a Hybrid Model with both Hydrodynamics and Hadronic Boltzmann Descriptions

open access: yes, 2018
Correlations related to local charge conservation provide insight into the creation and evolution of up, down and strange charges in the quark-gluon plasma.

The influence of forest regrowth, original canopy cover and tree size on saproxylic beetles associated with old oaks [PDF]

open access: yes, 2000
Abandoned management has caused many sites with free-standing, large oaks (Quercus robur) to become more shaded. This study shows how forest regrowth affects beetle species associated with old oaks in south-eastern Sweden. Beetles were trapped by pitfall
