The role of biotic interactions in shaping distributions and realised assemblages of species: implications for species distribution modelling

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2012, Volume and Issue: 88(1), P. 15 - 30

Published: June 12, 2012

Predicting which species will occur together in the future, and where, remains one of greatest challenges ecology, requires a sound understanding how abiotic biotic environments interact with dispersal processes history across scales. Biotic interactions their dynamics influence species' relationships to climate, this also has important implications for predicting future distributions species. It is already well accepted that shape spatial at local extents, but role these beyond extents (e.g. 10 km 2 global extents) are usually dismissed as unimportant. In review we consolidate evidence methods integrating into distribution modelling tools. Drawing upon from contemporary palaeoecological studies individual ranges, functional groups, richness patterns, show have clearly left mark on realised assemblages all extents. We demonstrate examples within trophic groups. A range tools available quantify environmental predict occurrence, such as: ( i ) pairwise dependencies, ii using integrative predictors, iii hybridising models (SDMs) dynamic models. These typically only been applied interacting pairs single time, require priori ecological knowledge about interact, due data paucity must assume constant space time. To better inform development scales, call accelerated collection spatially temporally explicit data. Ideally, should be sampled reflect variation underlying environment large fine resolution. Simplified ecosystems where there relatively few sometimes wealth existing ecosystem monitoring arctic, alpine or island habitats) offer settings account may less difficult than elsewhere.

A meta‐analysis of biotic resistance to exotic plant invasions

Ecology Letters, Journal Year: 2004, Volume and Issue: 7(10), P. 975 - 989

Published: Sept. 6, 2004

Abstract Biotic resistance describes the ability of resident species in a community to reduce success exotic invasions. Although is well‐accepted phenomenon, less clear are processes that contribute most it, and whether those strong enough completely repel invaders. Current perceptions strong, competition‐driven biotic stem from classic ecological theory, Elton's formulation resistance, general acceptance enemies‐release hypothesis. We conducted meta‐analysis plant invasions literature quantify contribution competitors, diversity, herbivores soil fungal communities resistance. Results indicated large negative effects all factors except on invader establishment performance. Contrary predictions derived natural enemies hypothesis, reduced invasion as effectively competitors. significantly individual invaders, we found little evidence interactions repelled conclude rarely enable resist invasion, but instead constrain abundance invasive once they have successfully established.

Jack of all trades, master of some? On the role of phenotypic plasticity in plant invasions

Ecology Letters, Journal Year: 2006, Volume and Issue: 9(8), P. 981 - 993

Published: Aug. 1, 2006

Invasion biologists often suggest that phenotypic plasticity plays an important role in successful plant invasions. Assuming enhances ecological niche breadth and therefore confers a fitness advantage, recent studies have posed two main hypotheses: (1) invasive species are more plastic than non-invasive or native ones; (2) populations the introduced range of evolved greater range. These hypotheses largely reflect disparate interests ecologists evolutionary biologists. Because these sciences typically interested different temporal spatial scales, we describe what is required to assess at levels. We explore inevitable tradeoffs experiments conducted genotype vs. level, outline components experimental design identify levels, review some examples from literature. Moreover, invader may benefit as either Jack-of-all-trades, better able maintain unfavourable environments; Master-of-some, increase favourable (3) Jack-and-master combines level both abilities. This new framework can be applied when testing oriented hypotheses, promises bridge gap between perspectives.

Performance Comparisons of Co-Occurring Native and Alien Invasive Plants: Implications for Conservation and Restoration

Annual Review of Ecology Evolution and Systematics, Journal Year: 2003, Volume and Issue: 34(1), P. 183 - 211

Published: Nov. 1, 2003

▪ Abstract In the search to identify factors that make some plant species troublesome invaders, many studies have compared various measures of native and alien invasive performance. These comparative provide insights into more general question “Do plants usually outperform co-occurring species, what degree does answer depend on growing conditions?” Based 79 independent native-invasive comparisons, invaders were not statistically likely higher growth rates, competitive ability, or fecundity. Rather, relative performance natives often depended conditions. 94% 55 comparisons involving than one condition, native's was equal superior invader, at least for key in Most commonly, these conditions involved reduced resources (nutrients, light, water) and/or specific disturbance regimes. Independently conditions, leaf area lower tissue construction costs (advantageous under high light nutrient conditions) greater phenotypic plasticity (particularly advantageous disturbed environments where are frequent flux). There appear be few “super invaders” universal advantages over natives; rather, increased resource availability altered regimes associated with human activities differentially increase natives.

Is invasion success explained by the enemy release hypothesis?

Ecology Letters, Journal Year: 2004, Volume and Issue: 7(8), P. 721 - 733

Published: June 4, 2004

Abstract A recent trend in invasion ecology relates the success of non‐indigenous species (NIS) to reduced control by enemies such as pathogens, parasites and predators (i.e. enemy release hypothesis, ERH). Despite demonstrated importance host population dynamics, studies ERH are split – biogeographical analyses primarily show a reduction diversity introduced range compared with native range, while community imply that NIS no less affected than invaded community. broad review literature implies at least eight non‐exclusive explanations for this enigma. In addition, we argue has often been accepted uncritically wherever (i) appear larger, more fecund, or somehow ‘better’ either congeners region, conspecifics range; (ii) known conspicuously absent from range. However, all NIS, regardless their abundance impact, will lose natural scale. Given complexity processes underlie biological invasions, against simple relationship between ‘release’ vigour, impact NIS.

Invasive species are a major element of global change and contributing to biodiversity loss, ecosystem degradation, impairment services worldwide. Research is shedding new light on the ecological economic consequences invasions. New approaches emerging for describing evaluating impacts invasive species, translating these into monetary terms. The harmful effects invasions now widely recognized, multiscale programs in place many parts world reduce current future impacts. There has been an upsurge scientific research aimed at guiding management interventions. Among activities that receiving most attention have promise reducing problems risk assessment, pathway vector management, early detection, rapid response, mitigation restoration.
