Raman Signature of the Wings of the Globe Skimmer Dragonfly: Pantala flavescens

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectroscopy is used to confirm the presence of aliphatic and aromatic hydrocarbons and related derivatives including aldehydes, halides, alcohols, acids, esters, and phenols on the wings of Pantala flavescens. The analysis indicates that wing‐surface lipid composition is largely consistent across the three main ecological zones in Ghana. Notably,

Registro de alimentação insetívora oportunista em Artibeus lituratus (Olfers,1818) (Chiroptera, Phyllostomidae) em um parque urbano no município do Rio de Janeiro (Rio de Janeiro, Brasil)

open access: yesBiotemas, 2022
Morcegos frugívoros são comumente registrados em áreas alteradas e também nas cidades, utilizando praças e parques urbanos como área de vida. Como parte de um projeto de monitoramento de morcegos urbanos, exemplares foram capturados em um fragmento ...

Anisotropic community turn‐over at habitat edges informs on assembly drivers: simulation and empirical test on soil macrofauna

open access: yesOikos, EarlyView.
Biodiversity dynamics in heterogeneous landscapes is the result of a complex interplay between movement processes of organisms within and between habitat patches, and niche filtering processes due to spatially varying environmental conditions. Disentangling the relative influences of these different processes on community assembly and dynamics is a ...

Inter‐Annual Variation in Alpha and Beta Diversity of Benthic Macroinvertebrate Communities in Agricultural Ditches

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.

Insecta. La búsqueda de la clasificación perfecta Insecta. Searching for the perfect classification

open access: yesRevista de la Sociedad Entomológica Argentina, 2005
RESUMEN. La historia de la clasificación de los insectos es analizada desde el punto de vista de sus relaciones externas (e.g., Unirramia, Mandibulata, Atelocerata, Pancrustacea) e internas (e.g., Hexapoda, Insecta, Entognatha, Ectognatha, Dicondylia ...

Dietary differentiation of two co‐occurring common bat species (Eptesicus nilssonii and Pipistrellus pygmaeus)

open access: yesWildlife Biology, EarlyView.
Sympatric bat species can co‐exist and avoid interspecific competition via niche differentiation e.g. diet. Detecting dietary differences can be achieved by comparing dietary niches of sympatric and allopatric populations. If dietary overlap is higher in sympatry versus allopatry, co‐occurrence may be altering the dietary niche of the species.

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Phylogenetic analysis of mitochondrial protein coding genes confirms the reciprocal paraphyly of Hexapoda and Crustacea

open access: yesBMC Evolutionary Biology, 2007
Background The phylogeny of Arthropoda is still a matter of harsh debate among systematists, and significant disagreement exists between morphological and molecular studies.

A molecular phylogeny of Hexapoda

open access: yesArthropod Systematics & Phylogeny, 2006
We present a supermatrix approach to the phylogeny of Insecta that stemmed from a talk given at the 2nd Dresden Meeting on Insect Phylogeny (2005). The data included a fragment of the 28S (D1–D8) and complete sequences for the 18S, histone (H3), EF-1α, COI, COII, the 12S and 16S plus the intervening tRNA, and 170 morphological characters.
