Long-term insect censuses capture progressive loss of ecosystem functioning in East Asia

Science Advances, Год журнала: 2023, Номер 9(5)

Опубликована: Фев. 3, 2023

Insects provide critical ecosystem services such as biological pest control, in which natural enemies (NE) regulate the populations of crop-feeding herbivores (H). While H-NE dynamics are routinely studied at small spatiotemporal scales, multiyear assessments over entire agrolandscapes rare. Here, we draw on 18-year radar and searchlight trapping datasets (2003–2020) from eastern Asia to (i) assess temporal population trends 98 airborne insect species (ii) characterize associated interplay. Although NE consistently constrain interseasonal H growth, their summer abundance declined by 19.3% time prominent agricultural pests abandoned equilibrium state. Within food webs composed 124 bitrophic couplets, annually fell 0.7% network connectance dropped markedly. Our research unveils how a progressive decline numbers debilitates trophic regulation stability macroscale, carrying implications for security (agro)ecological resilience during times global environmental change.

Rapid and Repeated Climate Adaptation Involving Chromosome Inversions following Invasion of an Insect

Molecular Biology and Evolution, Год журнала: 2024, Номер 41(3)

Опубликована: Фев. 24, 2024

Abstract Following invasion, insects can become adapted to conditions experienced in their invasive range, but there are few studies on the speed of adaptation and its genomic basis. Here, we examine a small insect pest, Thrips palmi, following contemporary range expansion across sharp climate gradient from subtropics temperate areas. We first found geographically associated population genetic structure inferred stepping-stone dispersal pattern this pest open fields southern China greenhouse environments northern regions, with limited gene flow after colonization. In common garden experiments, both field groups exhibited clinal patterns thermal tolerance as measured by critical maximum (CTmax) closely linked latitude temperature variables. A selection experiment reinforced evolutionary potential CTmax an estimated h2 6.8% for trait. identified 3 inversions genome that were CTmax, accounting 49.9%, 19.6%, 8.6% variance among populations. Other variations outside inversion region specific certain populations functionally conserved. These findings highlight rapid reiterate importance behaving large-effect alleles adaptation.

Climate drives the long-term ant male production in a tropical community

Forecasting insect responses to environmental variables at local and global spatial scales remains a crucial task in Ecology. However, predicting future requires long-term datasets, which are rarely available for insects, especially the tropics. From 2002 2017, we recorded male ant incidence of 155 species ten malaise traps on 50-ha ForestGEO plot Barro Colorado Island. In this Panamanian tropical rainforest, were deployed two weeks during wet dry seasons. Short-term changes timing flying activity pronounced, compositionally distinct assemblages flew Notably, composition these oscillated consistent 4-year cycles but did not change 16-year study period.

Origins and Diversification of Myiasis Across Blowflies

Ecology and Evolution, Год журнала: 2025, Номер 15(2)

Опубликована: Фев. 1, 2025

ABSTRACT Parasitism represents a prevalent and successful ecological strategy that has evolved independently numerous times across metazoa. Understanding the origin diversification of parasitism is central question in evolutionary biology. This study investigated path leading to specific form blowflies known as myiasis, where larvae develop on or within vertebrate. We modeled myiasis‐associated traits, including trophic specialization (obligatory parasitism, facultative saprophagy), larval food substrate (necrotic, fresh both) developmental temperature (constant, variable blowfly phylogeny. Our results suggested ancestral state likely encompassed saprophagy with developing corpses necrotic tissues from wounds either homeothermic heterothermic hosts. Furthermore, our analysis highlights role an intermediate step for obligate blowflies, indicating pre‐adaptations parasitic lifestyle may serve stepping stones emerging parasitism. These findings shed light complex history vertebrate emphasizing importance critical transitional stage this process.

Heat stress effects on offspring compound across parental care

Proceedings of the Royal Society B Biological Sciences, Год журнала: 2025, Номер 292(2042)

Опубликована: Март 1, 2025

Heatwaves associated with climate change threaten biodiversity by disrupting behaviours like parental care. While care may buffer populations from adverse environments, studies show mixed results, possibly due to heat stress affecting different components. We investigated how impacts and offspring performance in the burying beetle Nicrophorus nepalensis under control (17.8°C) (21.8°C) conditions. focused on two critical periods: pre-hatching (carcass preparation) post-hatching (offspring provisioning). To disentangle vulnerability of these components stress, we reciprocally transferred carcasses prepared or females breeding both only one period did not alter reproduction, but when pre- periods experienced heatwaves, reproductive success declined. Females exhibited higher energy expenditure during provisioning, evidenced greater body mass loss. Notably, had long-lasting effects via carcass preparation, resulting smaller adult size mortality. These results highlight complexity environmental stressors care, suggesting that respond differently thus need be examined separately better understand responds to, buffers against, temperature stress.

Thermal performance under constant temperatures can accurately predict insect development times across naturally variable microclimates

Ecology Letters, Год журнала: 2021, Номер 24(8), С. 1633 - 1645

Опубликована: Май 25, 2021

Abstract External conditions can drive biological rates in ectotherms by directly influencing body temperatures. While estimating the temperature dependence of performance traits such as growth and development rate is feasible under controlled laboratory settings, predictions nature are difficult. One major challenge lies translating constant to fluctuating environments. Using butterfly Pieris napi model system, we show that rate, an important fitness trait, be accurately predicted field using models parameterized Additionally, a factorial design, accurate made across microhabitats but critically hinge on adequate consideration non‐linearity reaction norms, spatial heterogeneity microclimate temporal variation temperature. Our empirical results also supported comparison published simulated data. Conclusively, our combined suggest that, discounting direct effects temperature, insect generally unaffected thermal fluctuations.

Abstract Most studies in global change biology predict biological impacts of warming from information on macroclimates. organisms, however, live microhabitats with physical conditions which are decoupled to varying degrees those macroclimates depending partly organism body size. Small ectotherms a few millimetres length deep surface boundary layers such that their heat budgets dominated by different processes compared larger ectotherms, whose bodies emerge layers. We therefore hypothesized the size relative layer thickness generates patterns temperature variation for organisms same nominal habitats. tested this hypothesis community arthropods living subalpine plant combining models acquire high‐resolution time series operative temperatures, thermal imaging assess strength coupling between or arthropod and surrounding leaf cross‐scale approach infer distributions available small ectotherms. The model strongly influenced dynamics: bigger, warmer. were just warmer than surfaces, whereas large deviated >10°C. found similar naturally occurring arthropods. Temperatures insects closely tracked temperatures even full sun, surfaces. At whole scale, diversity surfaces was high, especially typically generating range microclimatic (for insects) Larger instead could move shaded sunny portions vary extent. bulk animal biodiversity consists terrestrial arthropods, majority associated at some point life cycles. distribution sizes determines how much is behavioural thermoregulation, thereby contributing potential response climate change.
