Collateral circulation that determines infarct progression in large vessel occlusion (LVO) is implicitly regarded as stationary. We investigated collateral circulation changes during interfacility transfer for endovascular thrombectomy (EVT) and its association with functional outcome in anterior circulation LVO stroke. Seventy consecutive patients with middle cerebral artery occlusion transferred for EVT from January 2017 to...

Genome size is a key genomic trait underpinning evolutionary potential and ecological adaptation in pathogens, yet its biogeographic patterns remain poorly understood. From New Zealand data, we quantify the influence of host traits versus environmental factors on biogeographic patterns of genome size in pathogenic fungi, and test whether these predictors differ between native and alien pathogens. Host plants were the strongest...

Freshwater eels of the Anguilla genus are experiencing global decline, largely driven by human activity. In Aotearoa‐New Zealand, tuna (both shortfin and longfin eels) are similarly affected, with habitat fragmentation and modification key drivers of their decline. We investigated the distribution and abundance of tuna across regional, catchment and reach‐level scales in an urban environment. We developed species distribution...

Global patterns of population genetic variation through time offer a window into evolutionary processes that maintain diversity. Over time, lineages may expand or contract their distribution, causing turnover in population genetic composition. At individual loci, migration, drift and selection (among other processes) may affect allele frequencies. Museum specimens of widely distributed species offer a unique window into the ge...

Leaf dry matter content (LDMC) is an important determinant of plant flammability. Investigating global patterns of LDMC could provide insights into worldwide plant flammability patterns, informing wildfire management. We characterised global patterns of LDMC across 4074 species from 216 families, revealing that phylogenetic and environmental constraints influence LDMC. LDMC varied across growth forms and taxonomic groups, disp...

Background Temperament is an important production trait in cattle and multiple strategies had been developed to generate molecular markers to assist animal selection. As nonsynonymous single nucleotide polymorphisms are markers with the potential to affect gene functions, they could be useful to predict phenotypic effects. Genetic selection of less stress-responsive, temperamental animals is desirable from an economic and welf...

Aim Species severely under‐represented in fossil pollen records leave gaps in interpretations and reconstructions of past vegetation. These ‘silent taxa’ leave little or no trace due to low pollen production, dispersal, preservation and taxonomic resolution. An approach for including them is through associating them with other species with reliable pollen representation. Here, we demonstrate a method for selecting such a proxy...

Whose Crisis? The Global COVID-19 pandemic from the perspective of communities in Africa is an international research project that aims to investigate and represent the diverse experiences of the COVID-19 pandemic from those marginalized by mainstream media and policy influence. This article focuses on the multidimensional effects of the generalized lockdown policy in an agrarian community in Nigeria. The project engaged parti...

Understanding and managing the response of marine ecosystems to human pressures including climate change requires reliable large-scale and multi-decadal information on the state of key populations. These populations include the pelagic animals that support ecosystem services including carbon export and fisheries. The use of research vessels to collect information using scientific nets and acoustics is being replaced with techn...

Reef islands are considered highly vulnerable to the impacts of anthropogenic climate change. While existing studies provide evidence of high dynamism and predominant stability over recent periods of sea-level rise, efforts to statistically link recorded morphological changes to processes are limited. We analyse shoreline changes across an expansive region of diverse oceanographic and climatic conditions and assess those obser...

Rapid advances in hardware and software, accompanied by public- and private-sector investment, have led to a new generation of data-driven computational tools. Recently, there has been a particular focus on deep learning—a class of machine learning algorithms that uses deep neural networks to identify patterns in large and heterogeneous datasets. These developments have been accompanied by both hype and scepticism by ecologist...
