Incorporating light pollution into projections of the future distribution of Aspisoma sticticum Gemminger, 1870 under climate change in South America

open access: yesInsect Conservation and Diversity, EarlyView.
Climate‐only models predict severe habitat contractions by 2100, especially in the Amazon, Cerrado and Caatinga, while southern and coastal Atlantic Forest areas remain refugial. Including artificial light at night increased projected stability and apparent suitability gains, especially in central and eastern South America.

Fire‐driven forest degradation enhances termite activity and accelerates litter decomposition in the Amazonia rainforest

open access: yesInsect Conservation and Diversity, EarlyView.
Forest degradation increased termite‐mediated litter decomposition, whereas no such effect was detected in undisturbed forests. Reduced ant predation and altered forest conditions were associated with higher termite abundance and faster litter decomposition.

Low Rates of Kaolin in Different Application Periods Reduce Diaphorina citri Population and Huanglongbing Incidence in Commercial Citrus Orchards

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.

Role of the tomato MARS1/ROUGH gene encoding a LYSINE‐SPECIFIC HISTONE DEMETHYLASE 1 in adventitious root and fruit skin formation

open access: yesJournal of Integrative Plant Biology, EarlyView.
The tomato mars1/rough mutant displays enhanced root regeneration and rough fruits due to ectopic cell proliferation. The causal gene encodes a lysine‐specific histone demethylase that normally maintains gene silencing. Its loss alters histone methylation, upregulating several genes, including those B‐type cyclins involved in tissue‐specific cellular ...

Going silent? Evidence for independent losses of acoustic communication in tree crickets (Insecta, Orthoptera, Grylloidea, Oecanthidae)

open access: yesJournal of Systematics and Evolution, EarlyView.
Our ancestral state reconstruction in tree crickets reveals multiple independent and irreversible losses of sound‐producing and ‐receiving structures, supporting the convergent evolution of the silent phenotype. We demonstrate strong evolutionary integration between forewings and tympana, although the discovery of ‘silent listeners′ and ‘deaf singers ...

Genetic, phenotypic, and ecological differentiation indicate a new cryptic and threatened species in the orchid genus Epidendrum from Alcatrazes Island, southeastern Brazil

open access: yesJournal of Systematics and Evolution, EarlyView.
Epidendrum insularis occurs on the remote Alcatrazes Island in the southeastern Brazilian coast. The description of this new cryptic species was only possible by the joint use of molecular markers, reproductive experiments, flower morphometry, functional traits, and community analysis.
