Birch Leaves as a Minefield: Do Trichomes Mediate Neonate Caterpillar Site Selection?

Entomologia Experimentalis et Applicata, EarlyView.
We investigated whether neonate Drepana arcuata caterpillars select leaf sites based on trichome distribution. Specifically, we assessed where larvae establish on leaves, quantified trichome distribution on leaves, and tested whether neonates avoid leaf trichomes. Neonates preferentially established and fed on areas with fewer trichomes, especially the

Freqüências de corte e intensidades de desfolha em duas cultivares de alfafa (Medicago sativa, L). 1. peso, número, produção estacional e dinâmica de aparecimento das brotações basilares Cutting frequencies and defoliation intensities on two alfalfa (Medicago sativa, L) cultivars. 1. weight, number, seasonal production and dynamic of appearance of basal shoots

Revista Brasileira de Zootecnia, 1999
O experimento foi realizado em Piracicaba, SP, durante um ano, com duas cultivares de alfafa (Crioula e CUF-101), plantadas em vasos a céu aberto. O peso e o número de brotos basilares foram mensurados.

Does the munch affect the bunch? Using community science to explore insect herbivory and fruit production in an understory plant

Ecological Entomology, EarlyView.
We used iNaturalist records, a longitudinal field survey, and a simulated herbivory experiment to explore how insect herbivory factors are associated with Cornus canadensis fruit production. Naturally observed internal and external insect herbivory was mostly low intensity and did not have a strong relationship with fruit production.

Effect of Grazing Intensity and Frequency on Forage Accumulation and Agronomic Characteristics of Tropical Mixed Pastures

Grasses
This study evaluated combinations of defoliation frequencies and intensities to identify grazing strategies that optimize forage accumulation and morphological composition in mixed pastures of Marandu palisadegrass (Urochloa brizantha cv.

Genome assembly of Elcysma westwoodi provides insights into host‐plant cyanogenic glucoside detoxification and chemical defence gene evolution

Insect Molecular Biology, EarlyView.
A chromosome‐level genome of Elcysma westwoodi was assembled. The genome encodes 272 detoxification‐related genes. A single‐copy bCAS was retained for cyanide detoxification. CYP405A and CYP332A were recruited into cyanogenic defence evolution. UGT33A retained a conserved GT‐B fold and catalytic domains.

INTERDEPENDÊNCIA ENTRE OS PADRÕES DE DESFOLHAÇÃO E A MORFOGÊNESE DO CAPIM-BRAQUIÁRIA SOB INFLUÊNCIA DAS FEZES DEPOSITADAS POR BOVINOS

Ciência Animal Brasileira, 2014
The knowledge of interdependence between defoliation patterns and morphogenesis of grasses allows the identification of the effects of feces deposition by cattle on the pasture.

Functional memory of drought affects leaf chemical defenses and microbial interactions in aspen

New Phytologist, EarlyView.
Experimental design of the common garden study. Summary Drought is an important driver of tree mortality, but its long‐term impacts on trait expression remain poorly understood. Leaves are a key interface at which trees respond to abiotic stress, and foliar traits such as chemical defenses and microbial communities may play a role in determining post ...

Linking drought strategy to climate‐of‐origin in a widespread C4 grass: hydraulic traits, xylem anatomy and stomatal behaviour in Themeda triandra

New Phytologist, EarlyView.
Climate‐of‐origin of Themeda triandra populations used in this study. Summary Hydraulic, stomatal, and anatomical traits strongly influence plant performance under drought, but the extent to which these trait‐types are coordinated and relate to climate‐of‐origin remains vastly underexplored in herbaceous species relative to woody plants.

Coupled decline in growth and fine‐branching signals the onset of drought‐induced European beech mortality

New Phytologist, EarlyView.
Conceptual synthesis of drought‐induced mortality in European beech. Summary Severe and recurrent droughts have caused widespread canopy decline and mortality in European forests. Drought‐induced mortality occurs when structural damage and physiological dysfunction impair a tree's ability to recover, yet it remains unclear when trees transition from ...
