Green Anole lizards (Anolis carolinensis) deposit eggs in nests of the Trap Jaw Ant, Odontomachus brunneus
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
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
Published: 2020-11-13
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
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
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 [...]
Cushion plants act as facilitators for soil microarthropods in high alpine Sweden
Published: 2020-09-25
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences, Population Biology, Terrestrial and Aquatic Ecology
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
Published: 2020-09-23
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 [...]
Püllomen: an ethnoecological perspective of the Mapuche protector spirit insect
Published: 2020-09-18
Subjects: Anthropology, Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Anthropology, Social and Behavioral Sciences
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
Published: 2020-09-01
Subjects: Agriculture, Entomology, Environmental Studies, Life Sciences, Social and Behavioral Sciences, Urban Studies and Planning
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 [...]
Studies of insect temporal trends must account for the complex sampling histories inherent to many long-term monitoring efforts
Published: 2020-08-21
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences, Population Biology
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 [...]

Subjects: Agriculture, Apiculture, Biodiversity, Ecology and Evolutionary Biology, Entomology, Genetics and Genomics, Life Sciences
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 [...]
Desert Locust in India: The 2020 invasion and associated risks

Wind direction, often used in forecasting locust migration, indicates a non-zero probability of desert locust invasion in eastern Indian states. Apart from present controlling measures, we are additionally suggesting to be cautious about the eggs of locust as the rainfall associated with Super Cyclone Amphan has created a favorable breeding ground for the gregarious locust. Also reverse migration [...]
Facultative predation can alter the ant-aphid population
Published: 2020-04-05
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences
Although ant--aphid interactions are the most typical example of mutualism between insect species, some studies suggest that ant attendance is not always advantageous for the aphids because they may pay a physiological cost. In this study, we propose a new mathematical model of an ant--aphid system considering the costs of ant attendance. It includes both mutualism and predation. In the model, we [...]
Epicuticular compounds of Protopiophila litigata (Diptera: Piophilidae): identification and sexual selection across two years in the wild
Published: 2020-03-18
Subjects: Behavior and Ethology, Biochemistry, Biophysics, and Structural Biology, Ecology and Evolutionary Biology, Entomology, Evolution, Life Sciences
The epicuticular compounds (ECs) of insects serve both to waterproof the cuticle and, in many taxa, as pheromones that are important for various social interactions including mate choice within populations. However, ECs have not been individually identified in many species and most studies of their role in mate choice have been performed in a laboratory setting. Here we newly identify and [...]
Development time mediates the effect of larval diet on ageing and mating success of male antler flies in the wild
Published: 2020-03-17
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Entomology, Evolution, Life Sciences, Population Biology
High-quality developmental environments often improve individual performance into adulthood, but allocating toward early-life traits, such as growth, development rate, and reproduction, may lead to trade-offs with late life performance. It is therefore uncertain how a rich developmental environment will affect the ageing process (senescence), particularly in wild insects. To investigate the [...]
