To predict the threat of biological invasions to native species, it is critical that we understand how increasing abundance invasive alien species (IAS) affects populations and communities. The form this relationship across taxa ecosystems unknown, but expected depend strongly on trophic position IAS relative species. Using a global metaanalysis based 1,258 empirical studies presented in 201 scientific publications, assessed shape, direction, strength responses invader abundance. We also...
Abstract Amplified fragment length polymorphism (AFLP) fingerprint data are now commonly collected using DNA sequencers. AFLP genotypes still often scored by eye from such — a time‐consuming, error‐prone and subjective process. We present semi‐automated method of genotyping sequencer‐collected AFLPs at predefined locations (loci) within the fingerprint. Our uses thresholds AFLP‐polymerase chain reaction‐product fluorescence intensity (peak height) in order to: (i) exclude loci that likely to...
Summary Understanding the effects of intraspecific genetic diversity on structure and functioning ecological communities is a fundamentally important part evolutionary ecology may also have conservation relevance in identifying situations which coincides with species‐level diversity. Early studies within this field documented positive relationships between structure, but recent challenged these findings. Conceptual synthesis has been hampered because used different measures variation...
Abstract Genetic diversity may play an important role in allowing individual species to resist climate change, by permitting evolutionary responses. Our understanding of the potential for such responses change remains limited, and very few experimental tests have been carried out within intact ecosystems. Here, we use amplified fragment length polymorphism ( AFLP ) data assess genetic divergence test signatures driven long‐term simulated applied natural grassland at Buxton Climate Change...
Threatened species often have small and isolated populations where mating among relatives can result in inbreeding depression increasing extinction risk. Effective management is hampered by a lack of syntheses summarising the magnitude of, variation depression. Here we describe nature scope literature examining phenotypic/fitness consequences inbreeding, to provide foundation for future management. We searched articles documenting impact natural populations. Article titles, abstracts...
Conservation biologists have drawn up a range of guidelines for the conservation genetic diversity—to maximise chances that populations threatened species persist, and to conserve this variation its potential utility. However, our understanding effectiveness maintaining diversity in situ is limited. Furthermore, we lack information on how species-level mating system affects these strategies. We used British geographical ranges eight widespread but declining plant species, varying breeding...
Abstract Drought imposes stress on plants and associated soil microbes, inducing coordinated adaptive responses, which can involve plant–soil signalling via phytohormones. However, we know little about how microbial communities respond to phytohormones, or these responses are shaped by chronic (long-term) drought. Here, added three phytohormones (abscisic acid, 1-aminocyclopropane-1-carboxylic jasmonic acid) soils from long-term (25-year), field-based climate treatments test the hypothesis...
DNA extraction techniques that employ the reversible binding of to silica via chaotropic salts can deliver high-quality genomic from plant and animal tissues, while avoiding use toxic organic solvents. Existing this method are either prohibitively expensive, or applicable only a restricted set taxa. Here we describe cost-effective technique suitable for wide range taxa yields microgram quantities high-molecular-weight at throughput 192 samples per day. Our is particularly robust tissue...
Many endemic plant species belong to taxonomically complex groups. These endemics have often arisen as a consequence of recent and rapid evolutionary divergence facilitated by processes such hybridization, polyploidy and/or breeding system transitions. The dynamic nature in groups leads problems the implementation traditional species-based approaches for conservation biodiversity that they contain. Firstly, taxa interest can be difficult define identify, leading practical difficulties...
It is becoming apparent that genetic diversity can influence the species and structure of ecological communities. Here, we investigated intraspecific trait variation responsible for this relationship. We grew 10 genotypes sedge Carex caryophyllea, as monocultures, under standardized conditions measured traits related to morphology, growth, life history. The same had been prominent in determining multispecies experimental communities, equivalent diversity, which constituent plant varied...
Traits have been widely used in plant ecology to understand the rules governing community assembly, and characterize primary strategies that define structure ecosystem properties. Relatively little is known as whether traits are ecologically important at macroecological scales either variable, or of consequence fine within species. We measured trait variation populations grassland plants Festuca ovina L. Koeleria macrantha (Ledeb.) Schult., test hypothesis fine-scale intraspecific drives...
Urbanisation inevitably alters the chemical, physical and biological soil properties. Consequently, it modifies environmental services. The sealing of – covering surface with non-biological structures - has gained attention in urban area relation to flooding, loss carbon, function other problems, which can be mitigated introducing greenspaces areas. To understand impact on properties, beneath three pavement types (concrete, slab tarmac) from paired unsealed areas (representing four...
Abstract Reproductive and early‐acting life‐history traits are likely to be particularly important determinants of plant fitness under a changing climate. There have, however, been few robust tests the evolution these chronic climate change in natural ecosystems. Such studies urgently needed, evaluate contribution evolutionary population persistence. Here, we examine climate‐driven reproductive long‐lived perennial plant, Festuca ovina . We collected established plants F. from species‐rich...
