Reduced predation risk for melanistic pygmy grasshoppers in post-fire environments

open access: yesEcology and Evolution, 2012
The existence of melanistic (black) color forms in many species represents interesting model systems that have played important roles for our understanding of selective processes, evolution of adaptations, and the maintenance of variation. A recent study

Rethinking Face‐to‐Face Interaction: Lessons from Studies of “Autistic Sociality”

open access: yesSymbolic Interaction, EarlyView.
Face‐to‐face interaction is a foundational concept in microsociology. This article surveys the social experiences of autistic people, who are commonly known for having a strained relationship with interactions face to face. By interpretively reviewing and synthesizing the broader literature on “autistic sociality,” the article provides a nuanced ...

Day‐Ahead Scheduling for Dynamic Distribution Network Configuration Optimization Considering Reconfiguration Frequency Constraints

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
As distributed energy resources (DERs) penetration increases, complex power flows lead to challenges such as voltage violations, system congestion, and increase of distribution loss. To effectively address these issues and enhance energy efficiency, an hourly dynamic system configuration optimization method is essential, as traditional annual and ...

Timescale-invariant representation of acoustic communication signals by a bursting neuron [PDF]

open access: yes, 2009
Acoustic communication often involves complex sound motifs in which the relative durations of individual elements, but not their absolute durations, convey meaning.

Assessing habitat suitability for black grouse broods at the bioregional scale

open access: yesWildlife Biology, EarlyView.
The black grouse Lyrurus tetrix, a galliform species emblematic of the European Alps, is currently threatened by habitat change, particularly given the closure of heathland linked to the rising tree line at higher altitudes. The presence of heathlands in good ecological condition is, however, imperative for the species' reproduction.

Background matching, disruptive coloration, and differential use of microhabitats in two neotropical grasshoppers with sexual dichromatism

open access: yesEcology and Evolution, 2020
Cryptic coloration is an adaptative defensive mechanism against predators. Color patterns can become cryptic through background coloration‐matching and disruptive coloration.

Ferocious Fighting between Male Grasshoppers

open access: yesPLoS ONE, 2012
Contests among individuals over mating opportunities are common across diverse taxa, yet physical conflict is relatively rare. Due to the potentially fatal consequences of physical fighting, most animals employ mechanisms of conflict resolution involving

Cicada as a food for mammals: a global review and implications for mammal behaviour and populations

open access: yesWildlife Biology, EarlyView.
Cicadas (Hemiptera: Cicadidae) are among the most important insect prey for many vertebrate predators, including birds and mammals, owing to their large size and high nutritional value. Although the ecological roles of cicadas as prey for birds have been well documented, the interactions between mammals and cicadas are relatively unknown.
