Little difference in the carbon balance of ryegrass/white clover- and plantain-dominated swards under dairy grazingNARA Subscribed
Incorporating plantain into grazed pasture swards is proposed as an approach to reduce nitrate leaching and nitrous oxide emissions. However, consideration must be given to potential emission-swapping, such as a reduction in soil carbon (C), which can contribute to increases in atmospheric CO 2 . We compared the net ecosystem C balance (NECB) of two adjacent newly-sown paddocks (~ 3 ha each) of (i) traditional ryegrass and whi...
DiVert : A Global Database of Land Use and Management Effects on Local Vertebrate Abundance and DiversityNARA Subscribed
Motivation Given that land use is a major driver of biodiversity loss worldwide, it is key to understand how different land use types and management practices affect biodiversity. Existing global databases on biodiversity responses to land use generally distinguish only broad land use types, focus on a wide taxonomic coverage at the expense of detail or completeness, or do not include biodiversity in primary vegetation as a be...
Local and Landscape‐Level Environmental Conditions Drive Habitat Selection Across Terrestrial Mammal SpeciesNARA Subscribed
Aim Animal movements are a fundamental process affecting communities and ecosystems. Quantifying habitat selection across species and habitats is key for understanding how animals respond to environmental change. Currently, we lack comparative studies that examine how habitat selection varies across species traits and landscapes. We aim to quantify global patterns of habitat selection to help understand the fundamental drivers...
Anaemic Streams: Iron and Essential Trace Metals Frequently Limit Primary Producer BiomassNARA Subscribed
Metals are essential for microbial metabolism, yet their role as limiting nutrients in freshwater streams remains poorly understood. We quantified the prevalence of metal and nutrient (co‐)limitation of primary producers in 41 streams. Metal limitation was widespread with Fe limitation eliciting the strongest and most consistent biomass responses (50% of streams). Zn limitation was also common (33% of streams), marking the fir...
Thermal Adaptation of Bacterial and Fungal Growth in a Geothermally Influenced Soil TransectNARA Subscribed
Numerous studies have investigated microbial adaptation to increasing soil temperature, but limitations in experimental design hinder comprehensive understanding. These include short‐term laboratory studies with constant environmental conditions and field studies with few distinct temperature treatments. Here, we utilized a long‐term natural soil geothermal gradient in Aotearoa, New Zealand, ranging in mean annual soil tempera...
A Multi‐Modelling Approach for Informing the Conservation of a Cold‐Adapted Terrestrial Amphibian in the Face of Climate ChangeNARA Subscribed
Aim We aimed to assess potential climate change impacts on the distribution of a cold‐adapted terrestrial amphibian that shows strong intraspecific differentiation. Location Alps and Dinarides. Taxon Alpine salamander ( Salamandra atra ). Methods We built SDMs for each of two major intraspecific lineages ( S. a. atra , which is found throughout the Northern Alps, and S. a. prenjensis , which appears sparsely along the Dinaride...
Characterization of HIV variants from paired Cerebrospinal fluid and Plasma samples in primary microglia and CD4+ T-cellsNARA Subscribed
Despite antiretroviral therapy (ART), HIV persistence in the central nervous system (CNS) continues to cause a range of cognitive impairments in people living with HIV (PLWH). Upon disease progression, transmigrating CCR5-using T-cell tropic viruses are hypothesized to evolve into macrophage-tropic viruses in the CNS that can efficiently infect low CD4-expressing cells, such as microglia. We examined HIV-1 RNA concentration, c...
Genetic Determinants in MRSA Carriage and Their Association with Decolonization OutcomeNARA Subscribed
Methicillin-resistant Staphylococcus aureus (MRSA) colonization increases the risk of infection. Response to decolonization treatment is highly variable and determinants for successful decolonization or failure of eradication treatment are largely unknown. Insight into genetic predictors of eradication failure is potentially useful in clinical practice. The aim of this study was to explore genetic characteristics that are asso...
Habitat fragmentation due to dams is a well‐known threat to freshwater fish. Yet, the global consequences of fragmentation for the viability of freshwater fish populations are unknown. Here, we provide the first global assessment of the threats of dams to the persistence of freshwater fish species. We developed a global macroecological relationship between freshwater fish range size and body size and used this relationship to...
New Guinea is one of the last regions in the world with vast pristine areas and is home to many endemic species. However, extensive road development plans threaten the island's biodiversity. We quantified habitat fragmentation due to existing and planned roads for 139 terrestrial mammal species in New Guinea. For each species, we calculated the equivalent connected area (ECA) of habitat, a metric that takes into account the ar...
Effects of nutrient enrichment on freshwater macrophyte and invertebrate abundance: A meta‐analysisNARA Subscribed
External nutrient loading can cause large changes in freshwater ecosystems. Many local field and laboratory experiments have investigated ecological responses to nutrient addition. However, these findings are difficult to generalize, as the responses observed may depend on the local context and the resulting nutrient concentrations in the receiving water bodies. In this research, we combined and analysed data from 131 experime...
Land use diversification may mitigate on‐site land use impacts on mammal populations and assemblagesNARA Subscribed
Land use is a major cause of biodiversity decline worldwide. Agricultural and forestry diversification measures, such as the inclusion of natural elements or diversified crop types, may reduce impacts on biodiversity. However, the extent to which such measures may compensate for the negative impacts of land use remains unknown. To fill that gap, we synthesised data from 99 studies that recorded mammal populations or assemblage...
Context‐dependent responses of terrestrial invertebrates to anthropogenic nitrogen enrichment: A meta‐analysisNARA Subscribed
Anthropogenic increases in nitrogen (N) concentrations in the environment are affecting plant diversity and ecosystems worldwide, but relatively little is known about N impacts on terrestrial invertebrate communities. Here, we performed an exploratory meta‐analysis of 4365 observations from 126 publications reporting on the richness (number of taxa) or abundance (number of individuals per taxon) of terrestrial arthropods or ne...
The impacts of linear infrastructure on terrestrial vertebrate populations: A trait‐based approachNARA Subscribed
While linear infrastructures, such as roads and power lines, are vital to human development, they may also have negative impacts on wildlife populations up to several kilometres into the surrounding environment (infrastructure‐effect zones, IEZs). However, species‐specific IEZs are not available for the vast majority of species, hampering global assessments of infrastructure impacts on wildlife. Here, we synthesized 253 studie...
The transport and degassing pathways of volatiles through large silicic magmatic systems are central to understanding geothermal fluid compositions, ore deposit genesis, and volcanic eruption dynamics and impacts. Here, we document sulfur (S), chlorine (Cl), and fluorine (F) concentrations in a range of host materials in eruptive deposits from Taupō volcano (New Zealand). Materials analysed are groundmass glass, silicic melt i...
