Evaluation of Methods for Collecting Mosquitoes (Culicidae: Diptera) in Canopy and Ground Strata in the Brazilian Savanna

open access: yesTropical Medicine and Infectious Disease, 2022
The hand-net is the standard method for capturing mosquitoes with sylvatic diurnal activity in disease outbreaks in Brazil. However, occupational risks and biases related to the collectors’ abilities and attractiveness are important limitations.

Anti-aphrodisiac compounds of male butterflies increase the risk of egg parasitoid attack by inducing plant synomone production [PDF]

open access: yes, 2009
During mating in many butterfly species, males transfer spermatophores that contain anti-aphrodisiacs to females that repel conspecific males. For example, males of the large cabbage white, Pieris brassicae (Lepidoptera: Pieridae), transfer the anti ...

Morphological and life‐history trait plasticity of two Daphnia species induced by fish kairomones

open access: yesEcology and Evolution
Daphnia can avoid predation by sensing fish kairomones and producing inducible defenses by altering the phenotype. In this study, the results showed that the morphological and life‐history strategies of two Daphnia species (Daphnia pulex and Daphnia ...

Density-dependent adjustment of inducible defenses [PDF]

open access: yes, 2015
International audiencePredation is a major factor driving evolution, and organisms have evolved adaptations increasing their survival chances. However, most defenses incur trade-offs between benefits and costs.

Diel vertical migration strategies of zooplankton in oligotrophic Russell Pond, New Hampshire [PDF]

open access: yes, 2014
Russell Pond is an ultra-oligotrophic lake with low chlorophyll a (1.9 mg L-1), total phosphorus (3.4 mg L-1), high Secchi Disk (10.4 m) and high light transmission (water coefficient of water, kw=0.33). Vertical migration of Chaoborus, Bosmina, Daphnia,

Aquatic macroinvertebrate responses to native and non-native predators [PDF]

open access: yes, 2014
Non-native species can profoundly affect native ecosystems through trophic interactions with native species. Native prey may respond differently to non-native versus native predators since they lack prior experience.

Behavioral responses to odors from other species: introducing a complementary model of allelochemics involving vertebrates

open access: yesFrontiers in Neuroscience, 2015
It has long been known that the behavior of an animal can be affected by odors from another species. Such interspecific effects of odorous compounds (allelochemics) are usually characterized according to who benefits (emitter, receiver, or both) and the ...

A male-produced aggregation-sex pheromone of the beetle Arhopalus rusticus (Coleoptera: Cerambycidae, Spondylinae) may be useful in managing this invasive species. [PDF]

open access: yes, 2019
The longhorned beetle Arhopalus rusticus (Coleoptera: Cerambycidae, Spondylinae) is a common species in conifer forests of the Northern Hemisphere, but with global trade, it has invaded and become established in New Zealand, Australia, and South America.

“Emotional Nose”: The Hedonic Character of Olfaction and its Epistemological and Clinical Implications [PDF]

open access: yes, 2020
The olfactory system is the oldest device that most organisms have to perceive their physical and social environment. However, progressing in the evolutionary tree, the importance of the olfactory perception has decreased, and the sight has taken ...

Effects of the invasive Tilapia on the Common Spiny Loach (Cypriniformes: Cobitidae: Lepidocephalichthys thermalis) - implications for conservation

open access: yesJournal of Threatened Taxa, 2017
The introduction of invasive species leading to decline of freshwater fauna is a major concern for conservation biologists.  In this study we examined the effect of introduced Tilapia on the survival of the loach Lepidocephalichthys thermalis via ...
