Biodiversity conservation requires prioritization of areas for in situ conservation. [] Key Method Diversity is described by three quantitative methods: (1) hotspots of species richness, selecting areas richest in species, (2) hotspots of range-size rarity, identifying areas richest in narrowly endemic species, and (3) complementarity, prioritizing areas according to their greatest combined species richness. The biodiversity measures of species richness and range-size rarity show a great correspondence in…
Land Planarian Assemblages in Protected Areas of the Interior Atlantic Forest: Implications for Conservation
The abundance and richness of land planarians was high during the night and after rainfalls, suggesting an increased activity of flatworms under such conditions, and species turnover between sites contributed more to the total richness than the alpha diversity.
Hidden diversity in forest soils: Characterization and comparison of terrestrial flatworm’s communities in two national parks in Spain
This work analyzes for the first time in Europe terrestrial flatworm communities in protected areas belonging to the Red Española de Parques Nacionales, performing a first study of the species richness and community structure for European terrestrial planarian species at regional and local scale.
Terrestrial flatworm (Platyhelminthes: Tricladida: Terricola) diversity versus man-induced disturbance in an ombrophilous forest in southern Brazil
Terricola diversity is inversely related to the degree of habitat disturbance and there are species that prefer habitats located on the extreme right along the main axis of a detrended correspondence analysisordination and therefore can be considered as indicators of well preserved, natural habitats.
Community structure of land flatworms (Platyhelminthes, Terricola): comparisons between Araucaria and Atlantic forest in Southern Brazil
Community structure is clearly distinct between the two types of forest, as well as among fragments of the Araucaria forest; there are no apparent edge effects and the diversity indices of the twotypes of ombrophilous forest are not significantly different.
Inventário de planárias terrestres (Platyhelminthes, Tricladida) em remanescente de Floresta Estacional Decidual do Sul do Brasil
The analysis indicated that land planarian communities of the Turvo State Park and those of other areas with Deciduous, Semideciduous and Dense Ombrophilous Forests differ from those of Mixed Omb Phytochemical Forests of the region.
Selecting areas to protect the biodiversity of aquatic ecosystems in a semiarid Mediterranean region using water beetles
1. In this work, carried out in the province of Murcia, a representative semi-arid area of the Iberian Peninsula, water beetles were used as indicators to identify the aquatic ecosystems with the
Relative and absolute density estimates of land planaRians
Land planarians (Platyhelminthes) are likely important components of the soil cryptofauna, al‐ though relevant aspects of their ecology such as their density remain largely unstudied. We investi‐
Diet assessment of two land planarian species using high-throughput sequencing data
The integration of metagenomics with phylogenetics should be considered when establishing studies on the feeding habits of invertebrates, and four different methods of taxonomic assignment are tested and find that phylogenetic-based assignment methods outperform those based on similarity.


Species Richness, Endemism, and the Choice of Areas for Conservation
It is found that the use of Carnivora as an umbrella taxon is an unreliable method for invertebrate conservation and richness and endemism patterns were not generally similar between taxa.
Rare species, the coincidence of diversity hotspots and conservation strategies
SPECIES conservation in situ requires networks of protected areas selected for high conservation interest1–3. Throughout most of the world, however, there are neither the resources nor the time to
Large scale patterns of biodiversity: spatial variation in family richness
The regional biodiversity of terrestrial and freshwater seed plants, beetles, amphibians, reptiles and mammals is mapped worldwide at the family level, finding that a very high proportion of the families of each of the five taxonomic groups can be embraced within a small number of regions.
Biological Inventory Using Target Taxa: A Case Study of the Butterflies of Madagascar
To assess this approach to biological inventory, a species—rich genus and subgenus of endemic butterflies from the island of Madagascar were chosen as target taxa and were evaluated for information richness in comparison to the entire butterflies of Madagascar.
Complementarity and the use of indicator groups for reserve selection in Uganda
A major obstacle to conserving tropical biodiversity is the lack of information as to where efforts should be concentrated. One potential solution is to focus on readily assessed indicator groups,
Biodiversity inventories, indicator taxa and effects of habitat modification in tropical forest
A gradient from near-primary, through old-growth secondary and plantation forests to complete clearance, for eight animal groups in the Mbalmayo Forest Reserve, south-central Cameroon is examined, indicating the huge scale of the biological effort required to provide inventories of tropical diversity, and to measure the impacts of tropical forest modification and clearance.
Biodiversity Hotspots and Major Tropical Wilderness Areas: Approaches to Setting Conservation Priorities
The accelerating and potentially catastrophic loss of biotic diversity is unlike other environmental threats because it is irreversible. Given the rapid loss of biodiversity and limited resources

By concentrating on these hot-spot areas where needs are greatest and where the pay-off from safeguard measures would be greatest, conservationists can engage in a more systematised response to the challenge of large scale impending extinctions.
