Freshwater Reservoir, Ecological Traps and Source-Sink Dynamics

Diversity, 2022
Odonata are biodiversity indicators that adequately represent many aquatic and semi-aquatic animal species. We recorded over two field seasons a rich lentic community of Odonata (18 species) in a large artificial freshwater reservoir (ca. 55 ha) built 40

Immune function and parasite resistance in male and polymorphic female Coenagrion puella [PDF]

, 2006
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 ...

Field estimates of reproductive success in a model insect: behavioural surrogates are poor predictors of fitness [PDF]

, 2011
Understanding, and therefore measuring, factors that determine fitness is a central problem in evolutionary biology. We studied a natural population of Coenagrion puella (Odonata: Zygoptera) over two entire breeding seasons, with over a thousand ...

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.

Sex- and morph-specific predation risk: Colour or behaviour dependency?

European Journal of Entomology, 2004
The coexistence of discrete morphs within a species, with one morph more conspicuous than the other(s) is often thought to result from both sexual selection and predation.

Diversity and Community Structure of Dragonfly and Damselfly (Odonata) at the Selorejo Waterfall Area, Ponorogo Regency, East Java Indonesia

Jurnal Riset Biologi dan Aplikasinya, 2021
Selorejo Waterfall is a natural tourism area that is quite far from downtown Ponorogo and directly adjacent to the Gunung Sigogor Nature Reserve. Hence, this area has the potential as a natural habitat for dragonfly and damselfly.

Phenology determines seasonal variation in ectoparasite loads in a natural insect population [PDF]

, 2010
1. The extent to which individuals are parasitised is a function of exposure to parasites and the immune response, which in ectotherms may be associated with temperature. 2.

Odonata: Who They Are and What They Have Done for Us Lately: Classification and Ecosystem Services of Dragonflies

Insects, 2019
Odonata (dragonflies and damselflies) are well-known but often poorly understood insects. Their phylogeny and classification have proved difficult to understand but, through use of modern morphological and molecular techniques, is becoming better ...
