Behavioral, Ecological, and Morphological Data Suggest a Close Relationship Between the Ant Colobopsis truncata and the Gall Wasp Aphelonyx cerricola

Integrative Zoology, EarlyView.
Aphelonyx cerricola and the different stages that make this gall colonizable by ants. ABSTRACT Wasps of the family Cynipidae are known to induce galls of a species‐specific morphology, which during senescence provide a refuge for secondary insect fauna, especially ants.

TOXICITY OF Esenbeckia pumila Pohl (Rutaceae) ON Artemia salina AND Atta sexdens rubropilosa

Revista Caatinga, 2019
The number of studies on plant compounds with insecticidal activity has increased in recent years, and one of the primary targets of these compounds is leaf-cutter ants, which are considered the most important pests in Brazilian plantations, especially ...

Ants contribute to raspberry pollination in protected cropping systems

Agricultural and Forest Entomology, EarlyView.
Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

Acta Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

Controllable Intrinsic Surface Pattern Generation Using Slime Mold Simulations

Computer Graphics Forum, EarlyView.
Abstract Surface‐based pattern simulations have proven valuable for texture design and scientific visualization, but existing methods face several limitations. Most simulations either target a narrow range of pattern types (e.g. spots, branching) or support a broad range of patterns at the cost of time‐consuming parameter tuning.

Atratividade de Atta sexdens rubropilosa por plantas de eucalipto atacadas previamente ou não por Thyrinteina arnobia Atta sexdens rubropilosa attractiveness to eucalyptus plants previously attacked or not by Thyrinteina arnobia

Pesquisa Agropecuária Brasileira, 2004
O sistema de defesa induzido das plantas é ativado após a ocorrência do dano provocado por um herbívoro. O objetivo deste trabalho foi avaliar se plantas de eucalipto (Eucalyptus grandis) atacadas previamente por lagartas de Thyrinteina arnobia tornam-se

Tomato plants control leaf sodium levels to limit damage by Spodoptera littoralis larvae. [PDF]

New Phytol
Summary Sodium is an essential element for animal growth and survival. Here we test the hypothesis that plants exposed to insect feeding can translocate sodium from the feeding site to other plant organs as a defense strategy against phytophagous insects, which need sodium in their diet.

Curating the Unexpected: Stéphane Thidet's “Weeping Stones” Transformed During COVID‐19

Curator: The Museum Journal, EarlyView.
ABSTRACT A monumental work by French artist Stéphane Thidet became the nexus for an unexpected interaction between an art installation and wildlife. “Weeping Stones,” which presents a desert‐like world, devoid of greenery, was featured in an exhibition we co‐curated at the Genia Schreiber University Gallery, Tel Aviv, Israel, in January 2020.

Vibration of the plant substrate generated by workers' stridulation during fungus garden cultivation in Atta laevigata (Smith) (Hymenoptera: Formicidae)

EntomoBrasilis, 2018
. The communication between leaf-cutting ants occurs through chemical interactions and sound, which are important processes in the complex social system of these organisms.

Host plant use is driven by microclimate not nutritional quality in a grassland butterfly

Ecological Entomology, EarlyView.
Small Copper butterflies (Lycaena phlaeas) choose to lay eggs on host plants growing in warmer microclimates, despite lower nitrogen content. Bare ground created by European Moles increases host plant temperatures and weakens the negative relationship between nitrogen content and microclimatic warmth.
