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

The impact of climate-induced distributional changes on the validity of biological water quality metrics [PDF]
We present data on the distributional changes within an order of macroinvertebrates used in biological water quality monitoring. The British Odonata (dragonflies and damselflies) have been shown to be expanding their range northwards and this could ...

Bibliographic Guide to the Terrestrial Arthropods of Michigan: Supplement 1 [PDF]
A list of publications dealing with faunistic studies, range extensions, systematics, and identification of the terrestrial arthropods of Michigan is presented, primarily for the period of 1983-1987. Correlation is also made between earlier entomological

Sexual dimorphism, fresh water dispersal range, and prey items of Marine toads (Rhinella marina) in Lennox Head, Australia [PDF]
The invasive cane or marine toad (Rhinella marina) has spread across much of Australia since its initial introduction in 1935. Naturally found in Central and South America, R.

Immune function and parasite resistance in male and polymorphic female Coenagrion puella [PDF]
Background: Colour polymorphisms are widespread and one of the prime examples is the colour polymorphism in female coenagrionid damselflies: one female morph resembles the male colour (andromorph) while one, or more, female morphs are described as ...

Mating success is linked to reproductive success in males, but parameters influencing it are poorly known. The relationships between lifetime mating success (LMS), fluctuating asymmetry (FA), body size (SIZE), reproductive period (RP) and emergence date (

The objective of this work were to analyze the effect of predation byOdonata 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 ...

Insect larval development affects adult traits but the biometric relationships are usually poorly understood, including large odonates. In this study, measurements of morphological traits of larvae, exuviae and adults of Anax imperator were recorded ...

Threat to the predator suppresses defence of its prey
Many studies have shown that prey can optimize their defence mechanisms based on cues indicating predator presence and pressure. However, little is known about whether prey can assess the actual threat by considering both predator density and the ...
