Sampling efficiency of a protocol to measure Odonata diversity in tropical streams.

PLoS ONE, 2021
Odonata can be sampled following different types of protocols. In Brazil, the most used protocol is the scanning in fixed areas method, where a 100-meter transect is delimited in one of the stream margins, subdivided into 20 segments measuring 5 meters ...

Effect of the spatial heterogeneity on the predation of Scinax fuscovarius and Physalaemus cuvieri tadpoles by Odonata larvae - doi: 10.4025/actascibiolsci.v32i2.4835

Acta Scientiarum: Biological Sciences, 2010
The objective of this work were to analyze the effect of predation by Odonata naiads on two amphibian species with distinct habits – benthic and mid-water – and to verify whether the presence and architecture of macrophytes can mediate this interaction ...

Odonata of eastern Bangladesh with three new records for the country

Journal of Threatened Taxa, 2018
A study was conducted in the eastern region of Bangladesh to contribute to the knowledge of the country’s Odonata fauna.  A total of 75 species belonging to nine families was recorded during the study period from April 2014 to July 2016.

Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero

River Research and Applications, EarlyView.
ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.

Does the habitat structure control the distribution and diversity of the Odonatofauna?

Brazilian Journal of Biology
The statement that the habitat complexity and structure govern the abundance and diversity of biological communities has been widely investigated. In this context, we assumed the hypothesis of habitat heterogeneity, that is, the higher habitat complexity

OdoBD: An online database for the dragonflies and damselflies of Bangladesh.

PLoS ONE, 2020
Combining scientific data over a long-time period is necessary for generating large-scale datasets, which are an essential component of comparative analysis for understanding evolutionary processes.

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior

Integrative Zoology, EarlyView.
Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.
