Sponge-Associated Polychaetes: Not a Random Assemblage

open access: yesFrontiers in Marine Science, 2021
Polychaetes are among the most common marine organisms, and in many habitats they dominate both in species richness and abundance. They are often found in association with other organisms.

Can taxonomic richness be used as a surrogate for phylogenetic distinctness indices for ranking areas for conservation? [PDF]

open access: yesAnimal Biodiversity and Conservation, 2003
Several methods have been proposed for evaluating area conservation priorities. Here the performance of traditional approaches (taxonomic richness) versus newer methods of phylogenetic distinctness is compared using the results and data from three ...

Phylogenetic measures applied to the conservation of Mexican marsupials

open access: yesRevista Mexicana de Biodiversidad, 2015
The didelphimorphs in Mexico are found all over the country except for the Baja California Peninsula. The aim of this study was to use three methods to assess the phylogenetic diversity of the species: Marmosa mexicana, Tlacuatzin canescens, Caluromys ...

Diversity and composition of demersal fishes along a depth gradient assessed by baited remote underwater stereo-video. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Continental slopes are among the steepest environmental gradients on earth. However, they still lack finer quantification and characterisation of their faunal diversity patterns for many parts of the world.

Richness and taxonomic distinctness of cave invertebrates from the northeastern state of Goiás, central Brazil: a vulnerable and singular area [PDF]

open access: yesSubterranean Biology, 2019
The karst area of the northeastern state of Goiás comprises two main municipalities: São Domingos and Posse. São Domingos is inside the limits of a Full Protection Conservation Unit known as Parque Estadual de Terra Ronca (PETeR), where a high number of ...

Polyphasic Taxonomic Analysis Establishes Mycobacterium indicus pranii as a Distinct Species

open access: yesPLoS ONE, 2009
المتفطرة الهندية البرانية (MIP)، والمعروفة باسم Mw، هي كائن حي قابل للزراعة وغير ممرض، والذي، بناءً على نموه وخصائصه الأيضية، يصنف في مجموعة رونيون الرابعة جنبًا إلى جنب مع M. fortuitum و M. smegmatis و M. vaccae. تم اعتماد حداثة هذه البكتيريا لقدرتها المناعية على الخضوع لتحول أرومي مدفوع بمستضد الكريات البيض واختبار الجلد المتأخر لفرط الحساسية لدى ...

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 ...

Erratum to: Are taxonomic distinctness measures compliant to other ecological indicators in assessing ecological status? [PDF]

open access: yesMarine Pollution Bulletin, 2006
Assessing the ecological status, a concept implemented in the European Water Framework Directive [Directive of the European Parliament and of the Council 2000/60/EC establishing a framework for community action in the field of water policy PE-CONS 3639/1/00, 72 p.], requires the application of methods capable of distinguishing different levels of ...

The relationship between species richness and taxonomic distinctness in freshwater organisms [PDF]

open access: yesLimnology and Oceanography, 2005
Taxonomic distinctness is a newer biodiversity measure that emphasizes the average taxonomic relatedness between species in a community. We examined whether species richness (SR) and taxonomic distinctness (TD) were significantly related and whether they showed similar environmental relationships in regional data sets for various groups of freshwater ...

An approach to optimizing sampling effort for bioassessment surveys based on periphytic ciliates according to water depths in marine ecosystems

open access: yesEcological Indicators, 2021
The expectation analysis on taxonomic sufficiency of a community is a useful tool to optimize sampling effort for bioassessment of environmental/ecological quality status.
