ABSTRACT Aim Road networks are common landscape disturbances that can facilitate the spread of invasive plants. This study explored influence distance from road, habitat type and broader environmental factors in shaping distribution patterns both native species above‐ground vegetation soil seed banks.

Effects of human activities on the genetic characteristics of Phaius flavus populations

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

Published: March 7, 2024

Abstract Human activity often has profound effects on plant growth and evolution. Orchids are the most diverse group of flowering plants threatened by habitat fragmentation, over-harvesting, urbanization. A population Phaius flavus from Beikengding Mount (BM) in Fujian Province was divided into two patches road construction, its genetic characteristics were evaluated using restriction site-associated DNA sequencing (RAD-seq) data. The purpose this study is to explore impact construction evolution different within a population. Analysis revealed that diversity patch B slightly higher than BM P. . Principal component phylogenetic analyses, structure, differentiation, bottleneck detection indicated phase-independent differentiation between patches. Thus, Y013 village may have influenced level. This provides rational basis for research human activities biodiversity conservation.

Principal component phylogenetic analyses, structure differentiation analysis, bottleneck detection indicated relatively independent between patches. Thus, Y013 village may have influenced different level. provides case for understanding specific human activities populations, then biodiversity conservation. It is conducive formulating effective biological protection strategies mitigate damage inflicted biodiversity.

Understanding the taxonomic homogenization of road-influenced plant assemblages in the Qionglai mountain range: A functional and phylogenetic perspective

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 13

Published: Jan. 9, 2023

As an increasingly prevalent form of human activity, roads drive the taxonomic homogenization mountain plant assemblages, threatening global biodiversity. However, little is known about how impact functional and phylogenetic beta diversity these effects are related to homogenization. To understand mechanism triggered by roads, we used species absence/presence data from 76 plots (2 m*50 m) values for 12 traits measured on 978 interior roadside communities in Qionglai range, one temperate regions with highest richness world. We a structural equation modeling approach (SEM) consider several surrogates road disturbance (changes soil physicochemical properties presence or absence roads) causal relationship between three facets (taxonomic diversity, TBD; FBD PBD). The results suggest that TBD, PBD respond inconsistently despite strong positive correlations study area.

Significant Shifts in Predominant Plant Dispersal Modes in Pine Forests of the Southern Urals (Russia): Responses to Technogenic Pollution and Ground Fires

The purpose of this work was to assess the functional diversity herb–shrub layer com munities determined by their dispersal mode in pine boreal forests depending on two factors: (i) degree technogenic heavy metal pollution and (ii) time passed since last fire. We tested hypotheses: (1) communities diaspore decreases polluted disturbed recent fires; (2) abundance, i.e., participation anemochorous species communities, is relatively greater fires than unpolluted or that have not burned for a long time. analyzed 77 vegetation relevés made obtain impact gradient Karabash copper smelter (South Urals, Russia). studied also had different durations ground fire—from 1 60 years. Two classifications modes were used. found community predominant changed significantly response and, lesser extent, fires. In forests, importance with distance—anemochores zoochores—increased. This result suggests conducting specific study long-distance migration as possibly underestimated factor formation under severe disturbances. zoochores broad sense, including diaspores dispersed vertebrates invertebrates, increased post-fire succession. coincides known pattern increasing abundance zoochorous plants regenerative successions tropical forests.
