Exotic fishes that are phylogenetically close but functionally distant to native fishes are more likely to establish

Since Darwin's time, degree of ecological similarity between exotic and native species has been assumed to affect the establishment success or failure species. However, a direct test effect exotic-native on exotics is scarce because difficulty in recognizing failures establish field. Here, using database fish introduced into 673 freshwater lakes, we evaluate fishes by combining phylogenetic functional information. We illustrate that, relative other biotic abiotic factors, similarities were most important correlates establishment. While resident promoted successful establishment, led become established. Those phylogenetically close to, but functionally distant from, likely successfully. Our findings provide perspective reconcile naturalization conundrum suggest while relatedness allows pre-adapt better novel environments, they need possess distinct traits reduce competition with

Biological invasions are one of the major challenges to restoration post-mining sites. Most sites under technical reclamation with only a few left spontaneous vegetation processes. Therefore, we know little about alien plant species on spontaneously-vegetated post-coal mine heaps and how native community characteristics predict their establishment. To fill knowledge gap, aimed determine drivers colonisation heaps. Specifically, asked: (i) Which most successful why? (ii) What richness cover, they affected by community? (iii) does it mean for predicting threats from management? We recorded vascular abundance across 400 plots in Upper Silesia, Poland. calculated taxonomic functional and, using mixed-effects models, estimated predictors cover. found 65 heaps, comprising 20.4% all species, including 36 neophytes 29 archaeophytes. Amongst them – Erigeron canadensis , Solidago gigantea annuus Impatiens parviflora were frequent studied showed that significantly predicts Similarly, community-weighted (CWM) seed mass height However, CWM specific leaf area marginally richness. cover decreases Our findings revealed ecological significance niche-filling biotic acceptance hypotheses demonstrated exploring can help understanding invasibility management post-industrial vegetation.

Intraspecific and biogeographical variation in foliar fungal communities and pathogen damage of native and invasivePhragmites australis

Abstract Aim Recent research has highlighted that the relationship between species interactions and latitude can differ native invasive plant taxa, generating biogeographical heterogeneity in community resistance to invasions. In first study with foliar pathogens, we tested whether co‐occurring lineages of common reed ( Phragmites australis ) exhibit non‐parallel latitudinal gradients fungal communities, pathogen susceptibility damage, these patterns influence success invasion. Location North America. Time period 2015–2017. Major taxa studied Perennial grass P. . Methods We surveyed 35 field populations, spanning 17° comprising four phylogeographical lineages, including one endemic America from Europe. For each population, quantified percentage leaf damage cultured fungi diseased leaves, which identified using molecular tools. To assess had a genetic basis, inoculated plants 73 populations putative pathogens complementary garden experiment measured (i.e., area). Results isolated 84 taxa. lineage influenced composition but not diversity. Despite European being least susceptible three experiment, was similar providing no evidence release contributes Genetically based observed were isolate specific obscured by local environmental conditions field, where threefold higher for northern compared southern regardless lineage. Main conclusions Our results highlight host genetically strongly communities susceptibility, do translate field.

Rethinking Biological Invasions as a Metacommunity Problem

Perhaps more than any other ecological discipline, invasion biology has married the practices of basic science and application that science. The conceptual frameworks population regulation, metapopulations, supply-side ecology, community assembly have all to some degree informed management, prevention biological invasions. Invasion needs continue adopt emerging paradigms progress as both a applied This need is urgent problem continues worsen. development metacommunity theory in last two decades represents paradigm-shifting approach ecology emphasizes multi-scale nature biodiversity regulation. Work on metacommunities demonstrated even relatively simple processes at local scales are often heavily influenced by regional-scale driven primarily dispersal organisms. Often influence interacts with, or swamps, local-scale drivers like environmental conditions species interactions. An emphasis focus enable contribute strongly advancement biology. Propagule pressure invaders been identified one most important facilitating invasion, so concept, designed address how dispersal-driven dynamics affect structure, can directly many central questions Here we revisit concepts invasions—propagule pressure, biotic resistance, enemy release, functional traits, neonative species, human-assisted transport,—and view those through lens theory. In doing so, accomplish several goals. First, show work generated multiple predictions, models, tools be scenarios. Among these predictions invasibility should decrease with controls assembly, rates native species. Second, demonstrate framing invasions terms actually unifies seemingly disparate Finally, recommend courses action for control management invasive emerge from applying
