Crane flies (Limoniidae; Limoniinae) were sampled at national parks and protected areas across central to northern Thailand to observe patterns of species richness and faunal turnover in the Indo-Burma biodiversity hotspot. Prior to sampling, the crane fly fauna of this region was poorly known and no taxonomic keys existed for specimen identification. Utilizing a multi-access taxonomic key to the Limoniinae genera of the Oriental Region designed for this project, identification of collected… 

Linking the spatio‐temporal distribution of an edaphic crane fly to its heterogeneous soil environment

The abiotic (soil moisture) and biotic (plant community) factors defining a continuous turfgrass environment to the temporal population structure and spatial distribution of Tipula paludosa ontogenetic stages across 3 years of investigation are related.

Orchid bee (Hymenoptera: Apidae: Euglossini) assemblages from three different threatened phytophysiognomies of the subtropical Brazilian Atlantic Forest

Surprisingly, despite the short distance between MF and SF and that both forest remnants were located in the same studied region and under the same climatic conditions, the species richness detected was lower in MF than in SF, and the structure of these bee assemblages can vary significantly at the local and/or regional level.

Molecular phylogeny of sea-skaters (Halobates Eschscholtz, 1822), relationship between Halobatini and Metrocorini, and a catalogue of the subfamily Halobatinae (Hemiptera: Heteroptera: Gerridae)

It is confirmed that the limnic lifestyle of Metrocorini was ancestral in Halobatinae, and the marine lifestyle evolved only once in the common ancestor of Asclepios + Halobates, and that the open ocean was colonized at least three times inHalobates.



Low host specificity of herbivorous insects in a tropical forest

It is shown that most herbivorous species feed on several closely related plant species, suggesting that species-rich genera are dominant in tropical floras, and monophagous herbivores are probably rare in tropical forests.

Cranefly (Diptera: Tipuloidea) fauna of a boreal mire system in relation to mire trophic status: implications for conservation and bioassessment

It is implied, that a focus towards conservation and restoration of mire types with high trophic status would benefit also the conservation of cranefly diversity in the boreal ecoregion.

Terrestrial Arthropod Assemblages: Their Use in Conservation Planning

: Arthropods, the most diverse component of terrestrial ecosystems, occupy a tremendous variety of functional niches and microhabitats across a wide array of spatial and temporal scales. We propose

The Ecology of Coexistence. (Book Reviews: Species Diversity in Ecological Communities. Historical and Geographical Perspectives.)

The contributors emphasize the fact that ecological processes acting quickly on a local scale do not erase the effects of regional and historical events that occur more slowly and less frequently.


An extensive survey of the literature is conducted and a synthetic assessment of the degree to which variation in patterns is a consequence of characteristics of scale or taxon is provided.

Threatened biotas: "Hot spots" in tropical forests

10 areas that, a) are characterised by exceptional concentrations of species with high levels of endemism and b) are experiencing unusually rapid rates of depletion are identified, so conservationists can engage in a more systematised response to the challenge of largescale extinctions impending in tropical forests.

Historical biogeography, ecology and species richness.

Insect diversity of a Costa Rican dry forest: why keep it, and how?

The retention and maintenance of insect species richness in a tropical wildland is strongly rooted in the preservation of plant species richness, in maintaining habitat mosaics, in preserving a large diversity of habitats, and in recognizing the threat posed by insect crop associates in nearby agricultural lands.

Estimating terrestrial biodiversity through extrapolation.

The importance of using 'reference' sites to assess the true richness and composition of species assemblages, to measure ecologically significant ratios between unrelated taxa, toMeasure taxon/sub-taxon (hierarchical) ratios, and to 'calibrate' standardized sampling methods is discussed.
