The effects of pyridine hydrochloride on sublethal behavioural endpoints in the common shore crab, Carcinus maenasNARA Subscribed
Pyridine is a by-product of several industrial processes and is traditionally extracted from coal tar. In October 2021, a mass stranding of dead, twitching and moribund crustaceans, including edible crabs and lobsters, were observed off the northeast coast of England leading to speculation that pyridine released from dredging was the causal agent. This led to campaign groups asking for a cessation of dredging activity in the T...
Rooting for microbes: impact of root architecture on the microbial community and function in top- and subsoilNARA Subscribed
Background and aims Climate change and associated weather extremes pose major challenges to agricultural food production, necessitating the development of more resilient agricultural systems. Adapting cropping systems to cope with extreme environmental conditions is a critical challenge. This study investigates the influence of contrasting root system architectures on microbial communities and functions in top- and subsoil. Me...
Heterozygous activin receptor-like kinase 1 ( ALK1 ) mutations are associated with two vascular diseases: hereditary hemorrhagic telangiectasia (HHT) and more rarely pulmonary arterial hypertension (PAH). Here, we aimed to understand the impact of ALK1 mutations on BMP9 and BMP10 transcriptomic responses in endothelial cells. Endothelial colony-forming cells (ECFCs) and microvascular endothelial cells (HMVECs) carrying loss of...
Widespread selective sweeps throughout the genome of model plant pathogenic fungi and identification of effector candidatesNARA Subscribed
Identifying the genes underlying adaptation, their distribution in genomes and the evolutionary forces shaping genomic diversity are key challenges in evolutionary biology. Very few studies have investigated the abundance and distribution of selective sweeps in species with high‐quality reference genomes, outside a handful of model species. Pathogenic fungi are tractable eukaryote models for investigating the genomics of adapt...
The population biology of fungal invasionsNARA Subscribed
Fungal invasions are increasingly recognized as a significant component of global changes, threatening ecosystem health and damaging food production. Invasive fungi also provide excellent models to evaluate the generality of results based on other eukaryotes. We first consider here the reasons why fungal invasions have long been overlooked: they tend to be inconspicuous, and inappropriate methods have been used for species rec...
Postglacial recolonization history of the E uropean crabapple ( Malus sylvestris M ill.), a wild contributor to the domesticated appleNARA Subscribed
Understanding the way in which the climatic oscillations of the Quaternary Period have shaped the distribution and genetic structure of extant tree species provides insight into the processes driving species diversification, distribution and survival. Deciphering the genetic consequences of past climatic change is also critical for the conservation and sustainable management of forest and tree genetic resources, a timely endea...
Pathogen introductions into novel areas can lead to the emergence of new fungal diseases of plants. Understanding the origin, introduction pathways, possible changes in reproductive system and population size of fungal pathogens is essential in devising an integrated strategy for the control of these diseases. We used minisatellite markers to infer the worldwide invasion history of the fungal plant pathogen Leptosphaeria macul...
Ambrosia artemisiifolia is an aggressive North American annual weed, found particularly in sunflower and corn fields. Besides its economic impact on crop yield, it represents a major health problem because of its strongly allergenic pollen. Ragweed was imported inadvertently to Europe in the 18th century and has become invasive in several countries, notably in the Rhône Valley of France. It has recently expanded in both the Pr...
Ecosystem dynamics based on plankton functional types for global ocean biogeochemistry modelsNARA Subscribed
Ecosystem processes are important determinants of the biogeochemistry of the ocean, and they can be profoundly affected by changes in climate. Ocean models currently express ecosystem processes through empirically derived parameterizations that tightly link key geochemical tracers to ocean physics. The explicit inclusion of ecosystem processes in models will permit ecological changes to be taken into account, and will allow us...
Population structure and mating biology of the polygynous ponerine ant Gnamptogenys striatula in BrazilNARA Subscribed
Gnamptogenys striatula is a polygynous ponerine ant, whose colonies contain either several differentiated queens or several gamergates. Population structure, queen mating frequency and deviation from random mating were investigated in a north‐eastern Brazilian population. Eight workers from each of 33 queenright colonies and 17 queens and their progeny (20–40 offspring) were genotyped using eight variable microsatellite marker...
