Road corridors vegetation in the semi-arid region: functional trait diversity and dynamics

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Oct. 24, 2024

Road corridor vegetation plays a vital role in maintaining ecosystem stability and providing essential ecological services, particularly semi-arid regions where environmental conditions are challenging. In this study, we investigated the functional traits of native non-native plant species along N5 highway region Punjab, Pakistan. The methodology involved extensive field surveys systematic sampling herbaceous vegetation, followed by detailed measurements diversity. We classified 38 into categories analyzed their distribution, life forms, leaf spectra, flowering phenology. Our results revealed distinct patterns species, with exhibiting larger heights, sizes, surface areas compared to species. Additionally, displayed greater root stem biomass, indicative adaptations nutrient-poor soils water-limited environments. findings suggest that possess associated rapid growth resource acquisition, enabling them outcompete establish dominance roadside ecosystems. These provide valuable insights for understanding implications designing effective management strategies mitigate impacts on biodiversity resilience regions.

Anatomical characterization of Semi-arid Bignoniaceae using light and scanning electron microscopy

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: Jan. 30, 2025

The present research work was done to evaluate the anatomical differences among selected species of family Bignoniaceae, as limited data is available for this in Pakistan. Bignoniaceae a remarkable its various medicinal properties and characterization an important feature identification classification plants. In study, several structures were examined, including stomata type shape, leaf epidermis epidermal cell size, presence or absence trichomes crystals (e.g., prisms, raphides, druses). Three statistical tools-heat map analysis, correlation principal component analysis (PCA)-were used highlight distinctions similarities species. On both upper lower surfaces, polygonal, irregular, hexagonal cells with thick walls observed. patterns anticlinal detected: curved, straight, sinuous. Distinct stomatal types also identified across different For instance, sunken observed Kigelia africana Jacaranda mimosaefolia, while anomocytic found Oroxylum indicum, Pyrostegia venusta, Tecoma stans, Tecomella undulata, Mansoa alliacea, Heterophragma adenophylla, Handroanthus impetiginosus, Campsis radicans, Anemopaegma chamberlaynii.

Analysis of Understory Plant Community Assembly Differences in Moso Bamboo Forests in the Subtropical Evergreen Broad-Leaved Forest Region of Eastern China

Forests, Journal Year: 2025, Volume and Issue: 16(3), P. 478 - 478

Published: March 8, 2025

Moso bamboo (Phyllostachys edulis (Carrière) J. Houz.) forests are a vital forest type in subtropical China. This study investigates the diversity, floristic composition, and phylogenetic structure of understory vegetation these within evergreen broad-leaved eastern Using grid-based sampling, we calculated species diversity indices, employed correlation analysis, redundancy structural equation modeling to assess effects canopy closure, soil properties, topography. The exhibited high richness, with shrub layer demonstrating phytogeographic characteristics predominantly associated tropical distribution types, while herbaceous is characterized by temperate types. Canopy closure environmental factors significantly influenced showing clustered (NTI > 0, NRI 0) negative diversity. In contrast, herb displayed divergent < 0), shaped neutral stochastic processes, reflecting endemic taxa interspecific interactions. These findings emphasize need for targeted management practices conserve biodiversity, focusing on enhancing protecting their ecological

Climate change is impacting forest tree species adversely and making the ecological system vulnerable. The Himalayan cedar (Cedrus deodara), a keystone in Western forests, plays an important role but under increasing threats from natural anthropogenic pressures. current study analyses population structure, spatial distribution, environmental factors, future conservation strategies for populations Kashmir Himalayas.
