Maternal and paternal age effects on male antler flies: a field experiment

Christopher Angell, Rebecca Janacek, Howard D Rundle

Published: 2021-11-11
Subjects: Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences

In many species, parental age at reproduction can influence offspring performance and lifespan, but the direction of these effects and the traits affected vary among studies. Data on parental age effects are still scarce in non-captive populations, especially insects, despite species such as fruit flies being models in laboratory-based aging research. We performed a biologically relevant [...]

Comment on “Information arms race explains plant-herbivore chemical communication in ecological communities”

Ethan Bass, André Kessler

Published: 2021-09-23
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Plant Biology, Plant Sciences

Zu et al (Science, 19 Jun 2020, p. 1377) propose that an ‘information arms-race’ between plants and herbivores explains plant-herbivore communication at the community level. However, our analysis shows that key assumptions of the proposed model either a) conflict with standard evolutionary theory or b) are not supported by the available evidence. We also show that the presented statistical [...]

Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences

We present evidence of the recent introduction and quick spread of the European firebug Pyrrhocoris apterus in Australia, as documented on the citizen science platform iNaturalist. The first public record of the species was reported in December 2018 in the City of Brimbank (Melbourne, Victoria). Since then, the species distribution has quickly expanded into 15 local government areas surrounding [...]

Many parasitoids lack adult fat accumulation, despite fatty acid synthesis: A discussion of concepts and considerations for future research

Bertanne Visser, Cécile Le Lann, Caroline M. Nieberding, et al.

Published: 2021-08-25
Subjects: Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Physiology

Fat reserves, specifically the accumulation of triacylglycerols, are a major energy source and play a key role for life histories. Fat accumulation is a conserved metabolic pattern across most insects, yet in most parasitoid species adults do not gain fat mass, even when nutrients are readily available and provided ad libitum. This extraordinary physiological phenotype has evolved repeatedly in [...]

WHY DO INSECTS EVOLVE IMMUNE PRIMING? A SEARCH FOR CROSSROADS

Arun Prakash, imroze khan

Subjects: Animal Sciences, Ecology and Evolutionary Biology, Education, Entomology, Immunity, Immunology and Infectious Disease, Life Sciences

Until recently, it was assumed that insects lack immune memory since they do not have vertebrate-like specialized memory cells. Therefore, their most well studied evolutionary response against pathogens was increased basal immunity. However, growing evidence suggests that many insects also exhibit a form of immune memory (immune priming), where prior exposure to a low dose of infection confers [...]

Abundance- and biomass-based metrics of functional composition of macroinvertebrates as surrogates of ecosystem attributes in Afrotropical streams

Augustine Sitati, Frank Onderi Masese, Mourine J. Yegon, et al.

Published: 2021-08-16
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences

The composition of macroinvertebrate functional feeding groups (FFGs) has been used as surrogates of ecosystem attributes in aquatic ecosystems but studies that utilize such knowledge are still limited in the tropics. This study investigated the suitability of abundance- vs. biomass-based metrics of macroinvertebrate FFGs as surrogates of ecosystems attributes of the Sosiani-Kipkaren River in [...]

The evolutionary relevance of social learning and transmission of behaviors in non-social arthropods

Caroline M. Nieberding, Matteo Marcantonio, Raluca Voda, et al.

Published: 2021-08-05
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Entomology, Evolution, Life Sciences

Research on social learning has centered around vertebrates, but evidence is accumulating that small-brained, non-social arthropods also learn from others. Social learning can lead to social inheritance when socially acquired behaviors are transmitted to subsequent generations. Here, we first highlight the complementarities between social and classical genetic inheritance, using oviposition site [...]

Green Anole lizards (Anolis carolinensis) deposit eggs in nests of the Trap Jaw Ant, Odontomachus brunneus

Christina L. Kwapich

Published: 2021-06-30
Subjects: Entomology, Life Sciences

Squamates eggs are rarely found in ant nests, and are largely restricted to the nests of neotropical fungus gardening in the tribe Attini. Ponerine ant nests have not previously been reported as nesting cavities for squamates, including the Green Anole (Anolis carolinensis). The current study reports the association of Green Anole eggs and hatchlings with the subterranean nest chambers of the [...]

Challenges and opportunities of species distribution modelling of terrestrial arthropod predators

Stefano Mammola, Julien Pétillon, Axel Hacala, et al.

Published: 2020-12-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences

Species distribution models (SDMs) are emerging as essential tools in the equipment of many ecologists; they are useful in exploring species distributions in space and time and in answering an assortment of questions related to historical biogeography, climate change biology and conservation biology. Given that arthropod distributions are strongly influenced by microclimatic conditions and [...]

Combining surveys and on-line searching volumes to analyze public awareness about invasive alien species: a case study with the invasive Asian yellow-legged hornet (Vespa velutina) in Italy

Jacopo Cerri, Simone Lioy, Marco Porporato, et al.

Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology, Other Life Sciences

The Asian yellow-legged hornet (Vespa velutina) has been invading Italy since 2013, and it was subjected to management projects aimed at counteracting its spread and raising awareness about its impacts. In autumn 2019, we administered an on-line questionnaire to a convenience sample of 358 beekeepers in Italy. The questionnaire asked them about their sources of information about V. velutina, [...]

Introduced Vespa velutina does not replace native Vespa crabro and Vespula species

Luca Carisio, Jacopo Cerri, Simone Lioy, et al.

Published: 2020-11-03
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology

Alien species invasion could lead to the replacement of native species with similar ecological requirements. Vespa velutina is an invasive hornet recently established in Europe, that is raising concern due to the associated economic and ecological impacts toward managed and wild pollinators besides to the potential competition and replacement of native wasp species. This led to the inclusion of [...]

Insights from regional and short-term biodiversity monitoring datasets are valuable. A Reply to Daskalova et al. 2020 EcoEvoRxiv doi:10.32942/osf.io/cg3zs

Sebastian Seibold, Torsten Hothorn, Martin M. Gossner, et al.

Published: 2020-10-16
Subjects: Biodiversity, Biology, Entomology, Life Sciences, Research Methods in Life Sciences

Reports of major losses in biodiversity have stimulated an increasing interest in temporal population changes, particularly in insects, which had received little attention in the past. Existing long-term datasets are often limited to a small number of study sites, few points in time, a narrow range of land-use intensities and only some taxonomic groups, or they lack standardized sampling. While [...]
