In Antarctica, ice-free habitats occupy less than 1% of the continent’s terrestrial extent but nevertheless harbor eukaryotic biodiversity, which has been largely understudied due to logistical constraints. However, a novel combination of methods – repeated lasso regression linking environmental DNA traces with soil properties – has shown promise as a relatively easy and cost-effective means to predict the presence of phyla based on selected geochemical properties of soil samples, such as pH. In the December issue of Frontiers, Czechowski et al. share how the probability of detecting tardigrades (phylum Tardigrada) was higher in the absence of alkaline substrates, for instance, at sites in the Prince Charles Mountains. By establishing such biotic–abiotic relationships, this approach can help to inform future surveys for, and conservation of, Antarctic taxa.
Castilleja chromosa as seen in the Golden Gate Range, Nevada, USA. Hemiparasitic plants like C. chromosa parasitize other plants to gain key resources and can reduce host plant abundance. In their study published in the December issue of Ecology, Hodžić et al. show a positive correlation between hemiparasitic abundance and community evenness in plant communities across North America.
Coastal foredunes, such as the ones pictured here from Cape Lookout National Seashore, North Carolina, USA, form via biophysical feedbacks between sand and vegetation and are vulnerable to sea level rise and increased storm intensity. In their study published in the October issue of Ecosphere, Jay et al. used regression models and hierarchical partitioning to assess the relative roles of sand supply, vegetation, and beach morphology in shaping foredune morphology along a 300-km stretch of the US Central Atlantic coast. The authors found that sand supply and beach width explained the most variation in foredune height and width, while grass density and changes in grass density contributed significantly to foredune morphology change.
A pair of Rosy-faced Lovebirds (Agapornis roseicollis) in a backyard located in Phoenix, Arizona, USA. In their study published in the December issue of Ecological Applications, Andrade et al. look to untangle how bird species traits are linked to public perceptions. Iconic bird species tied to the regional desert environment were important for bolstering positive attitudes. However, the non-native—yet charismatic and gregarious—Rosy-faced Lovebird demonstrated how distinctive attributes can shape human perceptions of urban wildlife.
Hover flies (Diptera: Syrphidae) provide a multitude of ecosystem services including pollination and biological control. In their paper in the November issue of Ecological Monographs, Clem et al. examine for evidence and mechanisms of long-distance migration in Nearctic hover flies. Using stable hydrogen isotopes (δ2H) combined with abundance, morphological, and cold-tolerance data, they found that North American species like Eupeodes americanus (pictured here in central Illinois, USA) migrate south during autumn in response to encroaching winter conditions. Hover fly migration likely has major implications for ecosystems including pollen and nutrient transfer, and provision of sustainable pest management.
Many funders, societies, and publishers have adopted policies to facilitate the broadest reuse of research data and to support open science. Publishing data in a data repository can be a new, unfamiliar task. To reduce the learning curve, the Environmental Data Initiative has developed user-friendly software to make capturing and submitting data and metadata a simple process. An article in the October issue of the ESA Bulletin introduces ezEML to researchers who publish data and information managers who update data sets.
