Phylogenetic diversity vs species richness

As expected, phylogenetic diversity was well correlated with species richness among the elevational bands and among communities. At the community level, evergreen broad-leaved forests had the highest levels of species richness and phylogenetic diversity. Functional diversity could be a better indicator of resource partitioning and utilization in the communities than species richness (Dukes 2001 ), while phylogenetic diversity could add an evolutionary dimension (Gerhold et al. 2011 ). So far, there are few studies examining the role of phylogenetic diversity as a driver for alien species. Here, for the first time we linked species richness, phylogenetic and functional structure of bird assemblages in university campuses in northern China with plant species richness, glacial-interglacial climate change, contemporary climate, and anthropogenic factors to compare their relative roles in shaping urban bird diversity. Web. Aug 13, 2018 · As expected, species richness, density, and phylogenetic diversity were found to be the highest in low montane dry forest (LMDF) and the lowest in nivial zone (NZ), while the SES_PD was found to be the highest in low montane wet forest (LMWF) and the lowest in Afro-alpine zone (AZ) (Table 2 ). Figure 3 Open in figure viewer PowerPoint. Bats are reservoirs for multiple coronaviruses (CoVs). However, the phylogenetic diversity and transmission of global bat-borne CoVs remain poorly understood.

So far, there are few studies examining the role of phylogenetic diversity as a driver for alien species. Studies have found that endophytic fungi colonize almost all plants with rich diversity, which are affected by host plant species, organs, geographical location, seasonal climate, and other factors [ 10 ].

As expected, phylogenetic diversity was well correlated with species richness among the elevational bands and among communities. At the community level, evergreen broad-leaved forests had the highest levels of species richness and phylogenetic diversity. Also, the accuracy of GLMs increased when including the interactions that turned out to be important in machine learning models (70.4% vs 63.6% in species richness based on random cross-validation; 63.5% vs 45.2% in phylogenetic richness), highlighting the role of complex interactive effects among biotic and abiotic factors in shaping global.

Species diversity Species diversity is a term used to define the different number of species in an area (Species richness) and its abundance and the distribution of these species in that ecosystem. It's a measure of the variety in the ecosystem. Species diversity is a combination of species richness and species abundance. Species richness (SR) is a widely used biodiversity metric but lacks explanatory power when there are only a few species. Communities with low SR can have a wide variety of phylogenetic diversities (PD), which might allow for a better prediction of invasibility..

Web. Patterns of species richness and phylogenetic diversity were similar for both macrofungi and trees, but macromycete richness and diversity peaked at mid-elevations, whereas woody plant richness and diversity did not show significant trends with elevation. Phylogenetic similarity among sites was low for both groups and decreased as elevational. Web. Methods FD and PD indices might correlate simply because variation in species richness and evenness (referred to as co‐factors) influences both FD and PD values. We partition FD and PD indices into components influenced by species richness, evenness and species' (functional and phylogenetic) characteristics.

Web. Alpha Diversity Alpha diversity is the diversity within a particular area or ecosystem, usually expressed by the number of species (i.e., species richness) in that ecosystem. Alpha diversity estimates are calculated from a series of rarefaction analyses and hence dependent on sampling depth. The Alpha diversity tool takes abundance tables as input. Web. Species diversity Species diversity is a term used to define the different number of species in an area (Species richness) and its abundance and the distribution of these species in that ecosystem.

Web. Web. 摘要: Understanding the relationships between species,communities,and biodiversity are important challenges in conservation ecology.Current biodiversity conservation activities usually focus on species that are rare,endemic,distinctive,or at risk of extinction.However,empirical studies of whether such species contribute more to aspects of biodiversity than common species are still. Mar 06, 2015 · The relationship between species richness (SR) and phylogenetic diversity (PD) or (MPD) for the grassland studies used in this data synthesis.

May 26, 2018 · However, characterising biodiversity solely by species richness, or taxonomic diversity (TD) more generally, overlooks the various other types of variability that living things exhibit, notably the functional and phylogenetic facets of diversity (Pavoine and Bonsall 2011 ).. Phylogenetic diversity (PD) captures the shared ancestry of species, and is increasingly being recognized as a valuable conservation currency. Regionally, PD frequently covaries closely with species richness; however, variation in speciation and extinction rates and/or the biogeographic history of lineages can result in significant deviation.. Long-standing ecological theory proposes that diverse communities of plants should experience a decrease in herbivory. Yet previous empirical examinations of this hypothesis have revealed that plant species richness increases herbivory in just as many systems as it decreases it. In this study, I ask whether more insight into the role of plant diversity in promoting or suppressing herbivory can. Oct 21, 2022 · MPD and MNND (and their richness-standardized versions) provide complementary information about phylogenetic diversity. Specifically, MPD represents phylogenetic diversity at a whole-community level, whereas MNND quantifies phylogenetic diversity by incorporating only the distances of the closest relatives (Cadotte et al., 2018; Webb et al ....
