Gone with the waves: the role of sea currents as key dispersal mechanism for Mediterranean coastal and inland plant species

Plant Biology, Journal Year: 2024, Volume and Issue: 26(5), P. 832 - 841

Published: May 14, 2024

Abstract Thalassochory, the dispersal of propagules through marine currents, is a key long‐distance (LDD) mechanism with implications for global biogeography and particularly island colonization. The coastal plant species are generally assumed to be better adapted sea than those inland plants, but this hypothesis remains largely untested. We conducted experiments on four genera ( Juniperus , Daucus Ferula Pancratium ) compared traits among nine different habitats distributions. Our results showed that spp. P. maritimum have strong thalassochorous potential within Mediterranean Basin. Interestingly, we did not find clear association versus all tested genera, apart from endemic illyricum . These findings suggest thalassochory may more common previously assumed. apparently weak link syndrome ecology broadens possibility by also although considered poorly salt‐tolerant. Moreover, our reveal significant differences in between widespread species, do rule out an important role shaping distribution patterns archipelago flora. presented method replicable could used further studies larger set delineate trends or traits.

Genetic diversity and variations among Oklahoma and Texas sedge germplasm

Crop Science, Journal Year: 2025, Volume and Issue: 65(2)

Published: March 1, 2025

Abstract Sedges ( Carex spp.) are herbaceous perennials with more than 2100 species recognized, offering significant potential for use in mowed turf, landscape gardens, and ecosystem restoration. Breeding development of improved cultivars within various could have a broad impact across these industries. The lack information on genetic diversity variation most relevant has limited cultivar development. objective this study was to estimate the diversity, population structure, variability morphological reproductive traits 35 plants collected from Oklahoma Texas. A total 20,689 single nucleotide polymorphic markers were used characterization. Three subpopulations identified germplasm panel that largely determined by partially geographic locations. Substantial observed among species. In addition, substantial found reliability those moderate high 𝑖 2 = 0.38–0.83). findings provide insights into Texas, essential knowledge future breeding efforts. Additionally, highlights need research understand mechanisms underlying develop reliable molecular tools differentiation.

Habitat characterization and decline of Critically Endangered Onobrychis conferta subsp. conferta

Journal for Nature Conservation, Journal Year: 2024, Volume and Issue: 79, P. 126603 - 126603

Published: March 19, 2024

Rare endemic plant species are very susceptible to anthropogenic threats and natural changes, thereby facing a high risk of extinction. The Mediterranean Basin supports rich flora with percentages species. An iconic case narrow taxon is represented by Onobrychis conferta subsp. (Desf.) Desv. (Fabaceae). Management this requires better information on its habitat requirements population status. Field surveys historical records were used characterize the distribution O. in Tunisia. Habitats characterized using topography, soils, climate, land cover variables. Expeditions ten previously reported sites revealed presence only one previous recorded localities and, for first time, two new localities. We sharp decreasing trend total number plants per all locations over 6-year period. Our findings showed that current status Tunisia Critically Endangered (CR). faces an extremely extinction wild. Therefore, prompt comprehensive conservation actions needed ensure survival. propose recovery recommendations including situ ex actions. In aimed at minimizing effects identified create populations habitat. Ex include environmental education campaign seed preservation.

Hotspots in Transition: Mediterranean Amphibian Diversity Under Different Climate Scenarios

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: May 9, 2024

The Mediterranean Basin, a region renowned for its biodiversity, is experiencing unprecedented ecological changes owing to shifting climate patterns. This study employs niche modeling assess impacts of historical, current, and future scenarios on climatic suitability patterns 36 endemic amphibian species. incorporates diverse set environmental variables project species’ potential geographic distributions across significant events, including the Last Interglacial, Glacial Maximum, Mid-Holocene, as well projections 2050 2070 under various Representative Concentration Pathways (RCPs). resulting models underscore congruence predicted species-rich areas with established biodiversity hotspots, highlight influence precipitation distribution. Notably, reveals shifts in importance different landscape, certain regions projected transition from hotspots coldspots vice versa, response changes. These insights contribute broader discourse conservation priorities, emphasizing need adaptive strategies that can accommodate dynamic nature change. findings this serve call action preserving providing data-driven foundation informed planning critical hotspot.
