Preemptive Circular Defence of Immature Insects: Definition and Occurrences of Cycloalexy Revisited

open access: yesPsyche: A Journal of Entomology, Volume 2014, Issue 1, 2014., 2014
Cycloalexy was coined by Vasconcellos‐Neto and Jolivet in 1988 and further defined by Jolivet and collaborators in 1990 in reference to a specific type of circular defence. The term has been applied to numerous organisms, including adult insects, nymphs, and even vertebrates, but has lost precision with the accumulation of anecdotal reports not ...

Exploring Plant Surface Chemical Variability: Lettuce Leaf as Model

open access: yesPhysiologia Plantarum, Volume 177, Issue 5, September/October 2025.
ABSTRACT The plant cuticle has been traditionally believed to be a continuous lipophilic layer covering most aerial plant surfaces, but recent methodological advances based on Atomic Force Microscopy (AFM) enabled mapping the distribution of hydrophilic and hydrophobic areas in the papillae and pavement cells of rose petals and olive leaf trichomes ...

Effects of wind turbine noise on songbird behavior during nonbreeding season

open access: yesConservation Biology, Volume 38, Issue 2, April 2024.
Abstract Anthropogenic noise is one of the fastest growing, globally widespread pollutants, affecting countless species worldwide. Despite accumulating evidence of the negative impacts of wind turbines on wildlife, little is known about how the noise they generate affects ecological systems.

Intergroup encounters in pair‐living primates: Comparative analysis and a case study of pair‐living and monogamous owl monkeys (Aotus azarae) of Argentina

open access: yesAmerican Journal of Primatology, Volume 86, Issue 1, January 2024.
Intergroup encounters in pair‐living owl monkeys seem to be more related to infanticide avoidance and mate defense than to resource defense. Abstract The function of intergroup encounters (IGEs) may differ substantially among species of different group sizes and social organizations.
