ABSTRACT Climate change, a global threat of utmost significance, has the potential to trigger shifts in biodiversity distribution and emergence novel ecological communities. While considerable research focused on predicting impacts climate change range shift species, critical yet often overlooked aspect is role changing plants hot, arid, poorly known ecosystems. We employed an ensemble species modeling framework investigate how might affect spatial two significant indicator Ziziphus spina‐christi nummularia , within hot arid Khalijo‐Omanian ecosystem Iran. ran models for current using climatic variables then projected future periods (2041–2070 2071–2100) under different scenarios. These findings suggest that both respond differently Some regions may undergo expansion, whereas others experience contraction due shifting environmental conditions. Overall, are their towards higher latitudes as conditions evolve. Conservation management measures, including identification priority areas, crucial protecting these species.

The biosynthesis of secondary metabolites in plants, especially that phenolic compounds, is stimulated to protect against several environmental stress factors such as cold temperatures, drought, and UV-irradiance. As a result, when species occurs under different climatic conditions, differences accumulation are expected across distribution response the cues. However, our understanding compounds' natural variation limited, most knowledge on metabolite stems from experimental studies conducted controlled conditions. In this study we analyze content its relation geographic three closely related Hedera (H. helix, H. hibernica iberica) their southwestern range limits Iberian Peninsula (82 populations, 401 individuals). concentrates highest global richness Hedera, with sharing boundaries along latitudinal longitudinal gradient region.

Intercontinental disjunctions are one of the most attractive and interesting biogeographical patterns. Bryophytes often exhibit such distributions, which is partly explained by their great ability to disperse over long distances. However, intercontinental ranges sometimes a distorted reality caused existence unnoticed species. This study investigates whether disjunction between East Africa southern India moss Lewinskya firma reflects genuine distribution single species or implies pseudo-cryptic (whose morphological differentiation subtle have therefore been masked). An integrative taxonomic approach combining molecular methods (genotyping sequencing, GBS) was used, based on representation samples specifically collected from all major mountainous regions where this occurs. Two species, L. s. str. afroindica sp. nov. involved, whose completely overlap in Africa, although genetic distance differences leaf apex shape, vaginula hairs shape papillosity, spore ornamentation peristome constitution allow distinguishing both. In addition, range extends into both India. The phylogenetic reconstruction obtained shows certain degree Indian populations, they yet morphologically indistinguishable African populations. results thus highlight overlooked complexity bryophyte biogeography.
