A Community-Level Approach to Species Conservation: A Case Study of Falco naumanni in Southern Italy

Diversity, Journal Year: 2022, Volume and Issue: 14(7), P. 566 - 566

Published: July 14, 2022

The conservation of threatened species is prevalently oriented towards two management strategies, i.e., habitat-level and species-level approaches. former focused on improving the conditions habitat a certain species, whereas latter aimed at directly strengthening interest. In this work, we adopted different solution based community-level approach. Firstly, identified (predators, competitors, prey) that interact with interest (the lesser kestrel, Falco naumanni) in Southern Italy mapped all ecological interactions among these species. Secondly, built simulation framework entire network kestrel. Thirdly, simulated strategies could increase kestrel population stock by targeting it. We found can be effectively protected interacting natural changes abundance used to pro-actively predict dynamics population. Our study demonstrates approach highly appropriate local scale. methodological framework, qualitative modeling what-if scenarios, applied absence quantitative estimations stocks interaction strengths.

Time-dependent Interaction Modification Generated from Plant-soil Feedback

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2023, Volume and Issue: unknown

Published: Nov. 5, 2023

Abstract Pairwise interactions between species can be modified by other community members, leading to emergent dynamics contingent on composition. Despite the prevalence of such higher-order interactions, little is known about how they are linked timing and order species’ arrival. We generate population from a mechanistic plant-soil feedback model, then apply general theoretical framework show that modification pairwise interaction third plant depends its germination phenology. These time-dependent modifications emerge concurrent changes in microbe populations strengthened higher overlap plants’ associated microbiomes. The this specificity microbiomes further determines coexistence. Our widely applicable mechanisms systems which similar emerge, highlighting need integrate temporal shifts predict natural communities.

Are Plant–Soil Feedbacks Caused by Many Weak Microbial Interactions?

Biology, Journal Year: 2023, Volume and Issue: 12(11), P. 1374 - 1374

We used high-throughput sequencing and multivariate analyses to describe soil microbial community composition in two four-year field plant-soil feedback (PSF) experiments Minnesota, USA Jena, Germany. In descending order of variation explained, differed between the study sites, among years, bulk rhizosphere soils, soils cultivated by different plant species. To try identify organisms or communities that may cause PSF, we correlated growth responses with associated plants. found biomass was values on axes. These axes weighted dozens organisms, suggesting PSF not caused individual pathogens symbionts but instead 'many weak' plant-microbe interactions. Taken together, results suggest PSFs result from complex interactions occur within context a much larger whose is determined factors 'site' year, such as pH, type, weather.

Quantifying soil microbial effects on plant species coexistence: a conceptual synthesis

Published: Jan. 25, 2024

Soil microorganisms play a critical role in shaping biodiversity dynamics plant communities. These microbial effects can arise through direct mediation of fitness by pathogens and mutualists, over the past two decades, numerous studies have shined spotlight on dynamic feedbacks between plants soil as key determinants species coexistence. Such when modify composition community, which turn affects performance. Stimulated theoretical model developed 1990s, bulk empirical evidence for controls coexistence comes from experiments that quantify growth communities were previously conditioned conspecific or heterospecific plants. revealed microbes generate community ranging strong negative frequency-dependence to positive frequency-dependence.Even become recognized player determining outcomes, five years seen renewed interest expanding conceptual foundations this field. New results include extensions plant-soil feedback theory multi-species communities, re-interpretations metrics classic two-species models, frameworks integrate with processes like intra- inter-specific competition. Here, I review implications developments interpreting existing results, highlight proposed designs future reinforce assumptions enable more complete understanding regulation dynamics.
