Biotic interactions hold the key to understanding metacommunity organisation

Ecography, Journal Year: 2020, Volume and Issue: 43(8), P. 1180 - 1190

Published: May 19, 2020

Biotic interactions are fundamental drivers governing biodiversity locally, yet their effects on geographical variation in community composition (i.e. incidence‐based) and structure abundance‐based) at regional scales remain controversial. Ecologists have only recently started to integrate different types of biotic into assembly a spatial context, theme that merits further empirical quantification. Here, we applied partial correlation networks infer the strength dependencies between pairs organismal groups mapped imprints pond metacommunities. To do this, used comprehensive dataset from Mediterranean landscapes adopted perspective is best represented as network interacting groups. Our results revealed co‐variation among beta diversities multiple primarily driven by and, lesser extent, abiotic environment. These suggest ignoring may undermine our understanding mechanisms spatially extensive areas decrease accuracy performance predictive models. We found strong analyses which can be interpreted functional relationships several (e.g. macrophytes–macroinvertebrates, fish–zooplankton). Perhaps more importantly, support notion make crucial contributions species sorting paradigm metacommunity theory raise question whether these biologically‐driven signals been equally underappreciated other aquatic terrestrial ecosystems. Although research still required empirically capture importance across ecosystems resolutions extents, findings allow decision makers better foresee main consequences human‐driven impacts inland waters, particularly those associated with addition or removal key species.

Human population growth has increased demand for food products, which is expected to double in coming decades. Until recently, this been met by expanding agricultural area and intensifying agrochemical-based monoculture of a few species.

Herein, we assert that polyculture can ensure transition aquaculture towards sustainable development.

The ghosts of ecosystem engineers: Legacy effects of biogenic modifications

Functional Ecology, Journal Year: 2022, Volume and Issue: 38(1), P. 52 - 72

Published: Oct. 31, 2022

Abstract Ecosystem engineers strongly influence the communities in which they live by modifying habitats and altering resource availability. These biogenic changes can persist beyond presence of engineer, such modifications are known as ecosystem engineering legacy effects. Although many authors recognize legacies, some case studies quantify effects few general frameworks describe their causes consequences across species or types. Here, we synthesize evidence for legacies how consideration key traits improves understanding likely to leave persistent modifications. Our review demonstrates that ubiquitous, with substantial on individuals, processes. Attributes may promote persistence influential relate an engineer's traits, including its body size, life span living strategy (individual, conspecific group collection multiple co‐occurring species).

Positive species interactions shape species' range limits

The relationship between niche and distribution, especially the role of biotic interactions in shaping species' geographic distributions, has gained increasing interest last two decades. Most ecological research focused on negative species interactions, competition, predation parasitism. Yet relevance positive – mutualisms commensalisms have been brought to fore recent years by an number empirical studies exploring their impact range limits. Based a review 73 from Web Science search, we found strong evidence that can influence extent or ranges through diversity mechanisms. More specifically, while obligate mutualisms, tend constrain one both partners, facultative widen ranges. Nonetheless, there was more variation effects limits, pointing important context‐dependencies. Therefore, propose conceptual development this field will come studying context networks many across environmental gradients, since pairwise alone might overlook indirect environmentally‐contingent each other communities interacting species. Finally, our study also revealed key data gaps limit current understanding pervasiveness ranges, highlighting potential avenues for future theoretical experimental work.

RETRACTED: Advantage of Species Diversification to Facilitate Sustainable Development of Aquaculture Sector

Biology, Journal Year: 2022, Volume and Issue: 11(3), P. 368 - 368

Published: Feb. 25, 2022

Intensified agrochemical-based monoculture systems worldwide are under adoption to meet the challenge of human population growth and ever-growing global demand for food. However, this path has been opposed criticized because it involves overexploitation land, few species, excessive input agrochemicals, adverse impacts on health environment. The wide diversity among polyculture practiced across globe created confusion over priority a single strategy towards sustainable aquaculture development safer products. Herein, we highlight significance integrated practices in conveying successful transition industry development. So far, established thought is that precise selection aquatic species focus compatible complementary combinations supposed facilitate rapid progress food production with more profitability sustainability. Therefore, advantages diversification discussed from an ecological perspective enforce expansion. This account asserts diverse range can promote synergies farmed enhance system resilience, enable conservation, decrease footprints, provide social benefits such as diversified income local security.

Facultative mutualisms: A double‐edged sword for foundation species in the face of anthropogenic global change

Ecology and Evolution, Journal Year: 2020, Volume and Issue: 11(1), P. 29 - 44

Published: Dec. 4, 2020

Ecosystems worldwide depend on habitat-forming foundation species that often facilitate themselves with increasing density and patch size, while also engaging in facultative mutualisms. Anthropogenic global change (e.g., climate change, eutrophication, overharvest, land-use change), however, is causing rapid declines of species-structured ecosystems, typified by sudden collapse. Although disruption obligate mutualisms involving known to precipitate collapse coral bleaching), how (i.e., context-dependent, nonbinding reciprocal interactions) affect ecosystem resilience uncertain. Here, we synthesize recent advancements combine these model analyses supported real-world examples, propose may pose a double-edged sword for species. We suggest amplifying self-facilitative feedbacks species, can increase species' resistance stress from anthropogenic impact. Simultaneously, mutualism dependency generate or exacerbate bistability, implying potential when the mutualism's buffering capacity exceeded, recovery requires conditions improve beyond initial point (hysteresis). Thus, our work emphasizes importance acknowledging conservation restoration but highlights risk relying face change. argue significant caveats remain regarding determination feedbacks, empirical manipulation across gradients as way forward identify related nonlinear responses.

Uncovering patterns of freshwater positive interactions using meta‐analysis: Identifying the roles of common participants, invasive species and environmental context

Abstract Positive interactions are sensitive to human activities, necessitating synthetic approaches elucidate broad patterns and predict future changes if these altered or lost. General understanding of freshwater positive has been far outpaced by knowledge important relationships in terrestrial marine ecosystems. We conducted a global meta‐analysis evaluate the magnitude across habitats. In 340 studies, we found substantial effects, with facilitators increasing beneficiaries by, on average, 81% all taxa response variables. Mollusks particular were commonly studied as both beneficiaries. Amphibians one group benefiting most from interactions, yet few studies investigated amphibians. Invasive had stronger effects than non‐invasive facilitators. compared between high‐ low‐stress conditions no difference benefit subset that manipulated stressors. Future areas research include understudied beneficiaries, stress gradient hypothesis, space time influence declining whose elimination would jeopardise fragile interaction networks. Freshwater occur among wide range taxa, populations, communities ecosystem processes deserve further exploration.
