However, how these abiotic factors and their interactions drive <i>C. schmidtii</i> tussock wetland community dynamics and post-drought recovery are still unclear. Therefore, we selected three <i>C. schmidtii</i> tussock wetland types (drought, drought-rewetting, wetting) in the Momoge National Nature Reserve for further investigation. We combined relative importance value, alpha diversity, community similarity and productivity to explore drought and microtopography effects on plant community structure and function. Drought reduced biomass and <i>C. schmidtii</i> dominance, but increased richness and diversity. The degree of <i>C. schmidtii</i> dominance and community biomass was similar to those in the wetting wetland after drought-rewetting, but similarity was low. Plant diversity on tussock hummocks was lower than in hummock interspaces. Lower plant diversity was favorable for biomass accumulation among hummocks and in the overall community, but an opposite trend was found between hummock interspaces. Under drought, loss of <i>C. schmidtii</i> dominance and its biomass proportion resulted in lower hummock biomass, plant diversity, and richness compared to hummock interspaces. Furthermore, there would be significant differences in drought effects on plant similarity across the different microtopographies. Compared to hummock interspaces, hummock community structure was more similar to the overall community, was more susceptible to drought, and did not readily recover. Therefore, in restoration practice, <i>C. schmidtii</i> and hummock community structure should preferentially be restored, to ensure wetland recovery and stability.</p>","PeriodicalId":50994,"journal":{"name":"Community Ecology","volume":"1 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139422979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through a mensurative field experiment, we tested the hypothesis that functional aspects of the associated communities are related to structural and functional properties of the foundation species. Specifically, we contrasted invertebrate communities living in mussel (<i>Mytilus</i>) and seaweed (<i>Chondrus</i>) stands from the same rocky intertidal environments in Atlantic Canada. Both stands reach similar heights above the substrate, but they differ structurally (rigid mussel shells vs. flexible seaweed fronds) and functionally (mussels generate biowaste while seaweeds offer food for herbivores). Our data supported the hypothesis in various ways. Detritivory (mostly by oligochaetes) was more prevalent in mussel stands, while herbivory was more prevalent in seaweed stands. Predators were mostly mites and, consequently, they were more prevalent in mussel stands, as mites eat oligochaetes. Functional traits related to body and mobility types were also related to properties of the foundation species. Overall, we conclude that structural and functional properties of foundation species can predict functional aspects of the associated communities.

Thus it is increasingly important to monitor the changes occurring in the floral composition in such areas. The present study was therefore conducted across peri-urban habitats of Greater Kolkata, in order to establish a baseline data on plant species richness, invasive species co-occurrence, invader dominance and understand the bio-diversity pattern. Results showed a total of 62 plant species, mostly annual herbs, belonging to 29 families constituting the species richness in the study area. Both native (53%) and alien (47%) species were almost equally distributed and invasive species (32%) represented the majority among alien species. The findings also indicate that the species pool was dominated by sparsely distributed species. The number of invasive species varied from 2 to 9 per site, with 80% of sites supporting 3 or more species. <i>Alternanthera philoxeroides</i> and <i>Mikania micrantha</i> were the most frequently occurring invasive species. Overall, <i>M. micrantha</i> appeared to be the dominant species with 62% of sites with a high cover (&gt; 70%) and was found to be evenly distributed in areas.

We used carbon (C) and nitrogen (N) stable isotopes of hair and nail tissue to quantify overlap in dietary niche among American mink (<i>Neogale vison</i> von Schreber, 1776), American marten (<i>Martes americana</i> Turton, 1806), short-tailed weasel (<i>Mustela erminea</i> Linnaeus, 1758), and North American river otter (<i>Lontra canadensis</i> Schreber, 1777), and to quantify seasonal variation in diet among mink and marten. We collected tissue samples from the four species between 2015 and 2017 across an 18,000 km² area in central British Columbia, Canada. We hypothesised that the dietary niche breadth of the mustelid species would scale with body size. Standard ellipses suggested that mink had the broadest dietary niche and the only one that overlapped with all other species. Among marten, there was evidence of shifts in diet resulting from seasonal changes in the consumption of vertebrate prey. Marten and weasel occupied approximately the same isotopic space and their niches were contained fully within that of mink. Our results suggested that the coexistence of mink, marten, weasel, and river otter was driven in part by dietary niche partitioning. Differences in realized niche along spatial or temporal resource axes may have further contributed to preventing competitive exclusion among these closely related species. Although dietary analyses can provide insights on some components of interspecific competition, future investigations should include measures of spatial and temporal overlap in resource use.</p>","PeriodicalId":50994,"journal":{"name":"Community Ecology","volume":"6 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138512570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is urgent to clarify the distribution pattern and influencing factors of community biodiversity, especially the driving patterns of environmental factors under the conditions of invasive alien species. In this study, we investigated the effects of various environmental factors, especially altitude and <i>Ageratina adenophora</i> invasion, on forest community differentiation in <i>Pinus yunnanensis</i> forest in Panxi region, providing a strong theoretical basis for forest management and natural resource protection in this area. Based on the field survey data of 40 sample sites, a total of 18 environmental factors, including climate, terrain, soil and biology are selected, which may affect <i>Pinus yunnanensis</i> community. The methods of Two-way indicator species analysis (TWINSPAN), Redundancy analysis and Locally weighted linear regression are adopted by quantitative ecology. The effects of environmental factors on forest community type, species distribution pattern and species diversity were discussed. The results show that: (1) The <i>Pinus yunnanensis</i> community was divided into 4 types by TWINSPAN. (2) Altitude, annual mean temperature, soil pH, soil total phosphorus, <i>Ageratina adenophora</i> invasion were significantly correlated with forest community types and species distribution. (3) With the increase in altitude, the species diversity of <i>Pinus yunnanensis</i> community decreased firstly and then increased, and reached its lowest point at about 1800–2000 m a.s.l. With the increase in <i>Ageratina adenophora</i> invasion, the species diversity index of the community showed a downward trend. (4) The species diversity index of the tree layer was negatively correlated with the altitude. The species diversity index of herbaceous layer was negatively correlated with the <i>Ageratina adenophora</i> invasion intensity. Environmental factors had little influence on the species diversity index of shrub layer. It is suggested that the next research focus should be on setting up experimental areas for the invasion area of <i>Ageratina adenophora</i>, exploring scientific and effective removal methods, strengthening the restoration research and demonstration construction of the invaded ecosystem. By simulating and reconstructing the historical distribution dynamics of <i>Ageratina adenophora</i>, analyzing its diffusion trend and environmental interpretation, predicting the suitable areas in China under the background of climate change.

Different species compete and interact for resources at different physiological and developmental stages. However, most research has investigated inter-specific competition at the mature stage. We examined seed germination and seedling growth of two confamilial species, Albizia saman and Albizia lebbeck, and explored inter-specific competition at their early life stages, grown in a mixture of different proportions of seeds and seedlings through a series of replacement experiment. The experiment included germination and height growth tests for each species on its own, as well as three mixtures of species with ratios of 25:75, 50:50 and 75:25. We found that the germination speed and percentage, the probability of seedling emergence, and the seedling height were significantly higher in A. saman than in A. lebbeck . Moreover, in mixtures, we observed that A. saman exhibits higher germination speed and percentages compared to A. lebbeck . The increase in seedling height did not vary significantly among treatments when the seedlings of the studied species were mixed in different proportions. However, both species showed an apparent benefit when growing together, which was significantly influenced by A. saman in terms of inter-specific competition indexes. The knowledge of the early growth performance of these species and their inter-specific competition presented in this study may influence recruitment success and will be useful in understanding the population dynamics in the case of a mixed species plantation. Furthermore, our study suggests that there could be an impact of species mixture on the regeneration or recruitment process, even when the species are confamilial. Therefore, this information could be useful for selecting suitable species mixtures in any afforestation and reforestation activities.","PeriodicalId":50994,"journal":{"name":"Community Ecology","volume":"200 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135738856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
