Niche partitioning and trait tradeoff strategies enable plants to coexist under interspecific competition in restored wetlands

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Niche partition and traits tradeoff theory were primary strategies for plants coexistence. However, specific of remained to be verified guide community configuration biodiversity maintenance in ecological restoration. The variation composition niche breath utilized examine the temporal spatial strategies, respectively. Meanwhile, chi-square (χ2), Spearman rank correlation coefficient (rij), Ochiai index (OI) employed analyze interspecific relationship 30 predominant species from pool 220 vascular plants. Besides, Lotka-Volterra model was reveal five vegetation formations. About 62.41% pairs wetland partitioned while 37.58% overlapped. In scale, 60.5% occurred either spring or autumn 39.5% both seasons. significant change relative height (RH) coverage (RC) observed constructive auxiliary species. Height strategy ( ΔRHΔRC>1 ), enlarge ΔRHΔRC<1 ΔRHΔRC=1 ) Our finding testified that are objectively observable These findings on coexistence can used communities biological control alien invasive

Chaohu Lake is the fifth biggest freshwater lake in China and one of "Three Rivers Three Lakes" country-wide water air pollution prevention control plan.The complete cure a key task Hefei City.This study takes ecological surroundings region as precedent selects 21 warning signs from 4 aspects, namely, quality, meteorological indicators, resources, land, establishes assessment gadget area.The entropy weight TOPSIS approach ArcMap10.7 analyze surroundings, using elements spatial differentiation traits every to act references for administration, preservation ring region.The outcomes are: 1) basic circum-Chao vicinity (Feidong County, Feixi Lujiang Baohe District, City) used be negatively impacted all through 2018-2022, declined drastically 2019, remained essentially flat following period; 2) five-year comparative analyses location vicinity, typical City District was worst County best, followed by Feidong County; 3) 12-month evaluation modifications areas around suggests an upward trend, indicates small downward trend 2022; 4) evaluating weighting coefficients index, annual common attention nitrogen dioxide (C3), sulfur dioxide, awareness (C4), temperature (C9), irrigated arable land (C14) are main factors having impact on environment.

Geochemical sedimentary records of eutrophication and environmental change in Chaohu Lake, East China

Open Geosciences, Год журнала: 2024, Номер 16(1)

Опубликована: Янв. 1, 2024

Abstract Chaohu Lake is a representative lake in China that suffers from severe eutrophication and algal blooms. Understanding the changes lake’s eutrophic condition over time essential for its restoration management under background of global regional sustainability. In this context, compositions carbon nitrogen isotopes ( δ 13 C org 15 N, respectively), total organic (TOC), (TN), carbon–nitrogen ratio (C/N) were analysed to depict history state Lake, relationship with environmental changes. The result show before 1950s, primary productivity was low. During period 1950s 1970s, increased substantially due eutrophication. From 1970s present, as construction Floodgate Station, water replacement semi-closed gradually slowed nutrients began accumulate more rapidly. These conditions led enhanced rapid eutrophication, mainly caused by intensified human activities exogenous inputs. Our findings suggest geochemical records , TOC, TN, C/N ratios) sediment are capable recording important shifts temporal evolution lake-water trophic state.

Niche partition and traits tradeoff enable plants to coexist under interspecific competition

Research Square (Research Square), Год журнала: 2024, Номер unknown

The coexisting strategies of plants under interspecific competition driven the trajectory succession which concerned ecological success biodiversity maintenance in restored or created wetlands. To reveal mechanism and guide management vegetation recovery, 220 vascular from 19 lakeside wetlands were systematically analyzed. Ochiai index (OI) indicated that 62.41% 435 pairs species exhibited negative correlation compared with 37.58% positive correlation. coexistence heterospecific was mainly accomplished via spatial temporal niche partitioning, as well trade-offs height coverage plants. In terms partition, emergent found to have a wider breadth 1.67 ± 0.60 upland 1.28 0.36. temporal, 33.6% occurred spring, 26.8% autumn, 39.5% both seasons. Furthermore, according phenology, maturing summer, autumn accounted for 8.18%, 25.45%, 62.27%, respectively. These findings on can be used configuration communities
