Taxonomic distinctness and environmental assessment [PDF]

open access: yesJournal of Applied Ecology, 1998
The objectives of this paper are to test the performance of the taxonomic distinctness index, δ+, in a number of environmental impact scenarios, to examine its relationship with functional diversity and to examine the influence of habitat type and ...

Isoëtes sabatina (Isoëtaceae, Lycopodiopsida): Taxonomic distinctness and preliminary ecological insights [PDF]

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, 2021
Isoëtes sabatina is the rarest aquatic quillwort in Europe. Although recently found (2013) in Lake Bracciano (central Italy), the species is just one step away from extinction with an estimated population not exceeding 400 individuals and a spatial range

A taxonomic distinctness index and its statistical properties [PDF]

open access: yesJournal of Applied Ecology, 1998
For biological community data (species-by-sample abundance matrices), Warwick & Clarke (1995) defined two biodiversity indices, capturing the structure not only of the distribution of abundances amongst species but also the taxonomic relatedness of the ...

Taxonomic diversity and distinctness indices in assessment of weed communities

open access: yesActa Agrobotanica, 2012
This paper contains an analysis of taxonomic weed biodiversity in the cultivation of spring barley in the period of 1990-2004, grown in crop rotation after potato with a 25% share of this cereal (potato - spring barley - field pea - winter triticale) as ...

Taxonomic distinctness and species richness as measures of functional structure in bird assemblages

open access: yesOecologia, 2001
Most traditional "biodiversity" indices have an uncertain ecological interpretation, unfavourable sampling properties, and excessive data requirements.

The taxonomic distinctness of macroinvertebrate communities of Atlantic Forest streams cannot be predicted by landscape and climate variables, but traditional biodiversity indices can

open access: yesBrazilian Journal of Biology
Predicting how anthropogenic activities may influence the various components of biodiversity is essential for finding ways to reduce diversity loss. This challenge involves: a) understanding how environmental factors influence diversity across different ...

Taxonomic distinctness and conservation of a new high biodiversity subterranean area in Brazil [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2015
Subterranean environments, even though they do not possess a primary production (photosynthesis), may present high biodiversity, faunistic originality, endemism, phylogenetic isolations and unique ecological and/or evolution events, in addition to rare ...

Taxonomic distinctness in the diet of two sympatric marine turtle species

open access: yesMarine Ecology, 2016
Marine turtles are considered keystone consumers in tropical coastal ecosystems and their decline through overexploitation has been implicated in the deterioration of reefs and seagrass pastures in the Caribbean. In the present study, we analysed stomach

Taxonomically and Functionally Distinct Ciliophora Assemblages Inhabiting Baltic Sea Ice [PDF]

open access: yesMicrobial Ecology, 2021
AbstractCiliophora is a phylum of unicellular eukaryotes that are common and have pivotal roles in aquatic environments. Sea ice is a marine habitat, which is composed of a matrix of solid ice and pockets of saline water in which Ciliophora thrive.
