Medicinal and Aromatic Plants (MAPs) play a critical role in providing ecosystem services through their provision of herbal remedies, food natural skin care products, integration into local economies, maintaining pollinators’ diversity populations functioning. Mountainous regions, such as Chelmos-Vouraikos National Park (CVNP), represent unique reservoirs endemic MAP that require conservation prioritisation. This study aims to provide insights the sustainable management MAPs, contributing efforts protect Mediterranean biodiversity amid dual challenges climate land-use change, using suite macroecological modelling techniques. Following Species Distribution Modelling framework, we investigated vulnerability non-endemic MAPs changes. We examined potential shifts diversity, distribution, hotspots within CVNP. Our results revealed species-specific responses, with taxa facing severe range contractions initially expanding but eventually declining, particularly under change scenarios. Local are projected shift altitudinally, considerable area losses coming decades elevated species turnover predicted throughout CVNP, leading biotic homogenization. Climate changes jointly threaten calling for adaptive strategies, thus highlighting importance proactive measures, awareness raising, establishing plant micro-reserves, assisted translocation, promoting harvesting these offers vital managing global pressures, stressing need integrate ecological socioeconomic factors.

The relative influence of geographic and environmental factors on rare plant translocation outcomes

Journal of Applied Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 22, 2025

Abstract Conservation translocations are an established method for reducing the extinction risk of plant species through intentional movement within or outside indigenous range. Unsuitable environmental conditions at translocation recipient sites and a lack understanding species–environment relationships often identified as critical barriers to success. However, previous syntheses have drawn these inferences from analyses qualitative feedback rather than quantitative data. In this study, we use data set 235 conducted in US understand influences geographic factors on three metrics success: population persistence, next‐generation recruitment maturity. We random forest models quantify relative importance that characterize dissimilarity between source locations, position species' ranges niche derived ranges. also compare variables with more conventional predictors (e.g. founder size). Our results indicate can be insightful predicting outcomes. The climate suitability sites, estimated using distribution models, was strongest predictor whether persisted, populations situated suitable climates displaying greater persistence. Next‐generation maturity were best predicted by metrics; biotically limiting environments, including tropical regions soils high nutrient retention, well broadest precipitation niches, least likely attain benchmarks. Synthesis applications . study is one first important role spatial climatic rare provide novel perspective outcomes demonstrate opportunities improve success not only adhering practice guidelines but integrating modelling approaches into planning management processes.

Abstract Understanding the evolutionary responses of anadromous salmon and trout to climate change is critical for effective conservation planning. In this study, we conducted a comprehensive review literature published from 2010 2020 synthesize current knowledge on impacts these fish populations. Specifically, focused 199 papers that explored processes in response changing environmental conditions. Our analysis revealed several key themes, including interwoven influences human activities genetic variation, phenotypic traits, population dynamics. We found geographic patterns diversity are closely linked climatic gradients, highlighting importance strategies variation existing adaptive capacity. Additionally, temporal trends phenology, maturation age, fecundity indicate ongoing plastic change. Importantly, were identified as significant drivers maladaptation emphasize need targeted monitoring specific mitigate loss enhance study underscores identifying protecting areas high rare genes, particularly regions projected experience rapid shifts. conclusion, our findings identify strengths gaps research investigating role dynamics face By capitalizing new tools sequencing, genomic analysis, automated field data collection, can establish baselines tracking Better integration into projections future will lead more ensure long‐term resilience iconic species other wildlife.

Athrotaxis cupressoides is an endemic conifer restricted to montane areas of Tasmania. It slow‐growing and vulnerable the increasing wildfire activity associated with climate change. We explored novel idea that disused gravel pits could serve as artificial fire refugia for transplanted populations. compared survival, growth, response fertilizer nursery‐grown A. transplants in these refugia, which had mineral soils, burnt unburnt sites wilderness areas, organic soils. Survival over 16‐month trial increased initial transplant height was slightly higher (97%) than (89%). Height growth unfertilized plants slow, especially pits. However, boosted most strongly pits, rates similar those fertilized sites. Our results show it feasible reintroduce into populations eliminated by wildfire. They also demonstrate capacity reclaim creating new localized this iconic species. Thus, denuded can be re‐imagined help maintain other long‐lived but fire‐sensitive wild.

Shallow lake restoration typically focusses on the re‐establishment of macrophytes. The likelihood a species returning to site is contingent dispersal, proximity propagule sources, and on‐site propagule‐bank viability.

Conservation translocations are becoming common conservation practice, so there is an increasing need to understand the drivers of plant translocation performance through reviews cases at global and regional levels. The establishment Italian Database Plant Translocation (IDPlanT) provides opportunity review techniques used in 186 performed last 50 years heart Mediterranean Biodiversity Hotspot. We described information available IDPlanT these data identify outcomes. tested effect 15 variables on survival translocated propagules as monitoring date with binomial logistic mixed-effect models. Eleven significantly affected transplants: life form, site protection, material source, number source populations, propagation methods, propagule stage, planting habitat suitability assessment, preparation, aftercare, costs. integration vegetation studies selection suitable sites increased success efforts. Although posttranslocation watering had a generally positive outcome, other aftercare did not always increase transplant survival. Finally, we found that how funds were spent appeared be more important than actual amount spent. Italy area should account for complexity speciation, gene flow, migrations has led local adaptations implications choice constitution material.
