Does the DNA barcoding gap exist? – a case study in blue butterflies (Lepidoptera: Lycaenidae)
An analysis of intra- and interspecific variation in the butterfly family Lycaenidae which includes a well-sampled clade with a peculiar characteristic that facilitates the recognition of species as reproductively isolated units even in allopatric populations indicates that the "barcoding gap" is an artifact of insufficient sampling across taxa.
Disentangling a rainforest food web using stable isotopes: dietary diversity in a species-rich ant community
This study demonstrates that stable isotopes provide a powerful tool for quantitative analyses of trophic niche partitioning and plasticity in complex and diverse tropical omnivore communities.
Understorey versus canopy: patterns of vertical stratification and diversity among Lepidoptera in a Bornean rain forest
The observations on a wide taxonomic and ecological range of butterflies and moths indicate that tropical forest canopies hold a distinct and unique Lepidoptera fauna, whose species richness and abundance patterns differ from lower strata, however, the notion of tropical forestCanopies as peaks of terrestrial diversity does not hold uniformly for all taxa or guilds.
Preferences for sugars and amino acids and their conditionality in a diverse nectar‐feeding ant community
The results indicate that both interspecific variability in gustatory preferences and conditional effects such as competition and colony requirements affect resource selection in multispecies communities, including in niche partitioning of species-rich nectarivore assemblages.
Bottom‐up control and co‐occurrence in complex communities: honeydew and nectar determine a rainforest ant mosaic
The differential role of honeydew (as a specialised resource for dominant ants) and nectar (as an opportunistic resource for all ants including the co-occurring non-dominant species) provides a plausible structuring mechanism for the Australian canopy ant community studied.
Mud-puddling behavior in tropical butterflies: in search of proteins or minerals?
The strong attraction of male butterflies to nitrogen-rich resources suggests that, as in the case of sodium, these nutrients may increase reproductive success.
Sugar and amino acid composition of ant‐attended nectar and honeydew sources from an Australian rainforest
Comparing carbohydrates and amino acids from a representative spectrum of liquid sources used by ants in the canopy and understorey of a tropical rainforest in northern Queensland, Australia suggests variability in amino acids and carbohydrates is proposed to play a key role in ant preferences and nutrition.
From forest to farmland: diversity of geometrid moths along two habitat gradients on Borneo
Geometrid moths were collected on Mt. Kinabalu (Sabah, Malaysia) along two habitat gradients, ranging from primary rain forest to cultivated areas. During 135 nights' trapping in 1997, 4585
Unique elevational diversity patterns of geometrid moths in an Andean montane rainforest
Alpha-diversity of geometrid moths was investigated along an elevational gradient in a tropical montane rainforest in southern Ecuador, and there is evidence that the species-richness of other groups of herbivorous insects in the same area declines as altitude increases.
