Impact of environmental changes on the behavioral diversity of the Odonata (Insecta) in the Amazon

Scientific Reports, 2021
The odonates are insects that have a wide range of reproductive, ritualized territorial, and aggressive behaviors. Changes in behavior are the first response of most odonate species to environmental alterations.

Golf courses and wetland fauna [PDF]

, 2009
Golf courses are often considered to be chemical-intensive ecosystems with negative impacts on fauna. Here we provide evidence that golf courses can contribute to the support and conservation of wetland fauna, i.e., amphibians and macroinvertebrates ...

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.

Predation rate of dragonfly (Odonata: Libellulidae) on tilapia (Oreochromis niloticus Linnaeus 1758) and the availability of alternative preys (Insecta: Diptera: Chironomidae) to increase fish survival

Acta Scientiarum: Biological Sciences, 2023
The objective of this work was to evaluate the predation rates of two genera of Odonata Miathyria Kirby, 1889 and Erythemis Hagen, 1861 in post-larviculture of tilapia with and without availability of Chironomidae.

Evolutionary ecology of opsin gene sequence, expression and repertoire. [PDF]

, 2017
Linking molecular evolution to biological function is a long-standing challenge in evolutionary biology. Some of the best examples of this involve opsins, the genes that encode the molecular basis of light reception.

Chronic Exposure to High Concentrations of Road Salt Decreases the Immune Response of Dragonfly Larvae

Frontiers in Ecology and Evolution, 2019
Salinization of freshwater ecosystems, due to the application of road salts, is recognized as a potential threat to aquatic communities. Much of the research on the impact of salinity has focused on performance metrics in vertebrates, including ...

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 ...

Dominant predators mediate the impact of habitat size on trophic structure in bromeliad invertebrate communities [PDF]

, 2014
Local habitat size has been shown to influence colonization and extinction processes of species in patchy environments. However, species differ in body size, mobility, and trophic level, and may not respond in the same way to habitat size.
