Abstract The Antarctic midge, Belgica antarctica , is a wingless, non-biting midge endemic to Antarctica. Larval development requires at least 2 years, but adults live only weeks. nonfeeding mate in swarms and females die shortly after oviposition. Eggs are suspended gel of unknown composition that expressed from the female accessory gland. This project characterizes molecular mechanisms underlying reproduction this by examining differential gene expression whole males, females, larvae, as...
Abstract Seasonal progression is tracked in most animals by changes daylength, thus allowing reliable synchrony with abundant food and favourable developmental conditions. In polar regions, daylength varies extensively, fluctuating at the highest latitudes from persistent light to dark. The Antarctic midge Belgica antarctica has a narrow seasonal window which feed develop, previous work shows that this insect, despite having elements of circadian clock, remains continuously active when...
Freeze-tolerance, or the ability to survive internal ice formation, is relatively rare among insects. Larvae of Antarctic midge Belgica antarctica are freeze-tolerant year-round, but in dry environments, larvae can remain supercooled (i.e., unfrozen) at subzero temperatures. In previous work with summer-acclimatized larvae, we showed that freezing considerably more stressful than remaining supercooled. Here, these findings extended by comparing survival, tissue damage, energetic costs, and...
Predation by phagocytic predators is a major source of bacterial mortality. The first steps in protozoan predation are recognition and consumption their prey. However, the precise mechanisms governing prey phagocytosis protists, identities molecular cellular factors involved these processes are, as yet, ill-characterized. Here, we show that ability bacterivorous amoebae, Acanthamoeba castellanii, to recognize internalize Escherichia coli, prey, varies with LPS structure composition. presence...
Abstract Although scientists strive to accurately communicate their research, disconnects can arise between results and rhetoric. Some have regarded invasion as particularly prone using value-laden language incommensurate with the scientific facts or results. We addressed how authors used 10 near synonyms (words for which usage is similar but not completely overlapping) of negative-value word invasive. asked whether study findings (effect sizes) other factors predicted use. The use words...
The Rosenthal Islands lie along the western edge of Antarctic Peninsula. They are largely inaccessible and few research projects in area have focused on seabird colonies, so nothing has been known about arthropod fauna these islands. We conducted a preliminary survey arthropods associated with large penguin colonies. identified two species Collembola (Cryptopygus antarcticus Friesea grisea), four mites (Alaskozetes antarcticus, Hydrogamasellus racovitzai, Tectopenthalodes villosus Rhagidia...
Abstract Insects use rapid acclimation to enhance their tolerance of abiotic stresses within minutes hours. These responses are critical adaptations for insects and other small ectotherms tolerate drastic changes in temperature, hydration, or factors that can fluctuate precipitously with ambient conditions as a result behavior. Rapid cold-hardening, where brief exposure modest chilling cue cold tolerance, is the most thoroughly-studied these relatively little known about either triggered by...
Abstract The sequencing of whole or partial (e.g. reduced representation) genomes are commonly employed in molecular ecology and conservation genetics studies. However, due to costs, a trade-off between the number samples genome coverage can hinder research for non-model organisms. Furthermore, processing raw sequences requires familiarity with coding bioinformatic tools that not always available. Here, we present guide isolating set short, SNP-containing genomic regions use targeted...

Though they don't display much structural variation in their respiratory systems, scorpions exhibit variable lifestyles that may necessitate different aerobic capacities. These are largely conserved at the family level - typically, members of Buthidae do not burrow, unlike most Scorpionidae. Among digging scorpions, burrows can be dug overnight and reach depths up to 1m. Scorpions, like many other arachnids, utilize hemocyanin as a pigment hemolymph. We therefore hypothesized oxygen-binding...
Abstract Microhabitats with distinct biotic and abiotic properties exist within landscapes, this microhabitat variation can have dramatic impacts on the phenology physiology of organisms occupying them. The Antarctic midge Belgica antarctica inhabits diverse microhabitats along Western Peninsula that vary in macrophyte composition, hygric qualities, nutrient input, thermal patterns. Here, we compare seasonal physiological changes five populations B. living close proximity but different...
