Why do many parasitoids lack adult triglyceride accumulation, despite functioning fatty acid biosynthesis machinery?

Lipid reserves are a major energy source and play a key role in survival and reproduction. Lipid accumulation is a conserved metabolic pattern in insects, yet in most parasitoid species no adult lipid mass gain takes place, even when nutrients are consumed ad libitum. This deviating metabolic phenotype has evolved repeatedly in phylogenetically dispersed parasitoid species, and forms a conundrum [...]

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

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

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

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

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

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

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/

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 [...]

Cushion plants act as facilitators for soil microarthropods in high alpine Sweden

1. Cushion plants can have positive impacts on plant richness in severe environments and possibly across trophic levels on arthropods, an under-studied topic. 2. This study examined whether soil communities under cushions of Silene acaulis and Diapensia lapponica have higher richness and abundance of soil microarthropods (Acari, Collembola) than adjacent non-cushion vegetation; and whether [...]

GoogleTrends reflects the abundance of the Asian tiger mosquito (Aedes albopictus): a call for the web-based surveillance of invasive alien vector species

Subjects: Entomology, Environmental Studies, Life Sciences, Social and Behavioral Sciences

The Asian tiger mosquito (Aedes albopictus) is becoming widespread in Europe, where it can transmit some major arboviruses, including Chikungunya and Dengue. While surveillance initiatives are being implemented and harmonized between states, the spread of A.albopictus is outrunning them and cost-effective surveillance tools are needed. In this study, we tested whether on-line searches on Google [...]

Biodiversity plays an important role in cultural worldviews, influencing myths, stories, and spiritual beliefs of indigenous peoples. This short review explores an ecological phenomenon that may have influenced and contributed to the development of the Mapuche good spirit insect (Püllomen), which represents the spirit of someone who passed away and comes back to the world of the living providing [...]

Beekeeping in, of, or for the city? A socioecological perspective on urban apiculture

The term “urban beekeeping” has come to connote a host meanings --- sociopolitical, commercial, ecological, personal --- beyond the mere description of where bees and beekeepers happen to coincide. Yet these meanings are seldom articulated explicitly and seldom brought into critical engagement with the relevant fields of urban ecology and political ecology. Beginning with a brief account of the [...]

In a recently published study, Crossley et al. (2020, Nature Ecology & Evolution, “No net insect abundance and diversity declines across US Long Term Ecological Research sites”) examine patterns of change in insect abundance and diversity across US Long-Term Ecological Research (LTER) sites, concluding “a lack of overall increase or decline”. This is notable if true, given mixed conclusions [...]

Quantitative studies concerning the impact of climate change on pollinators are generally lacking. Relationship between honey bee diversity, present local adaptations and adaptive capacity of subspecies and ecotypes in the face of climate change is an urgent but rather poorly studied topic worldwide. Actually, such an effort lies at the crossroads of various fields of inquiry. Those include [...]
