Complete metamorphosis and microbiota turnover in insects

open access: yesMolecular Ecology, Volume 32, Issue 23, Page 6543-6551, December 2023., 2023
Abstract The insects constitute the majority of animal diversity. Most insects are holometabolous: during complete metamorphosis their bodies are radically reorganized. This reorganization poses a significant challenge to the gut microbiota, as the gut is replaced during pupation, a process that does not occur in hemimetabolous insects.

A review to the methods of personality measurements in wild animals 野生动物个性测量方法的综述

open access: yesWildlife Letters, Volume 1, Issue 3, Page 131-142, September 2023., 2023
One of the challenges in animal personality study is finding a suitable method to measure personality. Here, we outlined three methods (traits rating, behavioral coding, and experimentation) used in animal personality measurement. We found that traits rating was commonly used to test large‐sized animals (e.g., primates), behavioral coding was conducted

Sexual selection and predation drive the repeated evolution of stridulation in Heteroptera and other arthropods

open access: yesBiological Reviews, Volume 98, Issue 3, Page 942-981, June 2023., 2023
ABSTRACT Acoustic and substrate‐borne vibrations are among the most widely used signalling modalities in animals. Arthropods display a staggering diversity of vibroacoustic organs generating acoustic sound and/or substrate‐borne vibrations, and are fundamental to our broader understanding of the evolution of animal signalling.

Sex roles and sex ratios in animals

open access: yesBiological Reviews, Volume 98, Issue 2, Page 462-480, April 2023., 2023
ABSTRACT In species with separate sexes, females and males often differ in their morphology, physiology and behaviour. Such sex‐specific traits are functionally linked to variation in reproductive competition, mate choice and parental care, which have all been linked to sex roles.

Insulin peptides and their receptors regulate ovarian development and oviposition behavior in Diaphorina citri

open access: yesInsect Science, Volume 30, Issue 1, Page 95-108, February 2023., 2023
After female D. Diaphorina citri feed on young shoots, DcILP1, DcILP2, and DcIR in the insulin signaling system are upregulated. Interfering with these three genes reduces the expression level of DcRheb in the target of rapamycin signaling system and the reproduction‐related gene DcVg.

Time measurement in insect photoperiodism: The role of photophase duration and light intensity

open access: yesEuropean Journal of Entomology, 2022
The initial stages of diapause induction - as summer gives way to autumn - involve a process of time measurement in which the duration of daylength (or nightlength) is determined by a photoperiodic 'clock' based upon the circadian system. In many insects

Don't You Know That I'm Toxic? Wild Birds Learn to Avoid a Novel Aposematic Warning Signal. [PDF]

open access: yesEcol Evol
The foraging behaviours of predators towards aposematic prey have been studied extensively and there is much empirical evidence to support this theory. Often, studies involving wild species are relatively short‐term and so there is a possibility that any aversive behaviours exhibited by predators are merely neophobic. In this study, we ensure predators

A multi‐year dormancy strategy in a cabbage beetle population in southeastern China

open access: yesEcology and Evolution, Volume 12, Issue 5, May 2022., 2022
Our results showed that duration of diapause for adults collected in different years varied from several months to 5 years. Approximately 25.9%–29.2% of individuals showed prolonged diapause over the 5 years of observation. The temperature and photoperiod during induction have a significant influence on the incidence of prolonged diapause. Abstract The

Viral discovery and diversity in trypanosomatid protozoa with a focus on relatives of the human parasite Leishmania. [PDF]

open access: yes, 2018
Knowledge of viral diversity is expanding greatly, but many lineages remain underexplored. We surveyed RNA viruses in 52 cultured monoxenous relatives of the human parasite <i>Leishmania</i> ( <i>Crithidia</i> and <i> ...
