Unexpected Evolutionary Divergence of Tachykinin‐Positive Neurons Innervating the Central Complex in Hexapods [PDF]

J Comp Neurol
The central complex is a group of midline‐spanning neuropils in the brain of insects with a key role in goal‐directed orientation and navigation. Immunolabeling in 25 species, ranging from bristletails to flies, shows that neurons containing peptides of the tachykinin family of neuropeptides are present in most species studied.

Setting boundaries: Environmental and spatial effects on Odonata larvae distribution (Insecta)

Anais da Academia Brasileira de Ciências, 2015
Environmental characteristics and spatial distances between sites have been used to explain species distribution in the environment, through Neutral (space) and Niche theory (environment) predictions. We evaluated the effects of spatial and environmental

First record of Odonata nymphs from Karun River, south-west Iran [PDF]

Iranian Journal of Animal Biosystematics, 2014
Odonata fauna is poorly known in Iran and most of the previous studies deal with northern parts of the country, studying adult specimens. We sampled Karun River for aquatic insects in the city of Ahvaz in south-west of Iran during 2009–2011. As a result,

Higher gregarine parasitism often in sibling species of host damselflies with smaller geographical distributions [PDF]

, 2012
1. This study investigated inter-specific variation in parasitism by gregarines (Eugregarinorida: Actinocephalidae), among sibling species of damselflies (Odonata: Zygoptera), in relation to relative size of geographical ranges of host species.

Similar Survival Rates of Territorial and Sneaker Males in a Polymorphic Damselfly: A Multi-Year Study. [PDF]

Ecol Evol
Male Mnais damselflies occur in two genetically controlled morphs: an orange‐winged territorial morph that defends oviposition sites and actively courts females and a co‐occurring clear‐winged sneaker morph that does not defend territories or display, yet mates opportunistically with females.

The impacts of environmental warming on Odonata: a review [PDF]

, 2008
Climate change brings with it unprecedented rates of increase in environmental temperature, which will have major consequences for the earth's flora and fauna.

The development of sexual differences in body size in Odonata in relation to mating systems

European Journal of Entomology, 2007
Adult body size is the result of important environmental, maternal and/or genetic effects acting on animals during development. Here we investigate how sexual size dimorphism (SSD) develops in seven species of Odonata: Anax imperator, Cordulegaster ...

Species and life stages of Odonata nymphs sampled with large drift nets in two Wisconsin rivers [PDF]

, 2017
Because relatively few nymphs of Odonata are caught in most drift studies, they have been inconsistently reported and little is known about the species and life stages that are predisposed to drift.

Biogeographic regionalization of Odonata (Insecta) in the Neotropics: contrasting Anisoptera and Zygoptera spatial patterns [PDF]

Frontiers of Biogeography
The Neotropical region stands as a significant hotspot for Odonata diversity, yet comprehensive spatial patterns have remained less elucidated. This study aimed to provide a comprehensive biogeographical regionalization of the order Odonata across the ...
