Morphology and mechanical behavior of diatoms in wet and dry states studied using nano-XCT
BMC BiologyBackground Diatoms are widely studied biological objects because of their large variety of geometric shapes and their unique physical and chemical properties. They survive widely in nature within moisture.

Critical constraints to ecological buffering in a rapidly changing Arctic: A long‐term seabird study
Journal of Animal Ecology, EarlyView.Drawing on two decades of research in East Greenland, this study shows that little auks, key seabird indicators of Arctic ecosystem health, can adapt to rapid environmental change through behavioural flexibility. However, increasing storms and mercury pollution are pushing resilience to its limits, providing an early warning of broader Arctic ...

Temporary rivers are aquatic ecosystems that alternate periods of water flow with dry periods. Diatoms are a group of unicellular microalgae with a high colonizing ability, but little is known about their responses to drying.

Diatoms (Part V): Ecology [PDF]
, 1983 Diatoms are found in a wide variety of habitats. Fossil evidence suggests that diatoms are of relatively recent geologic origin in comparison to other algal groups. The oldest known fossil specimens come from the Jurassic Period (Vinyard 1979).

Journal of the Royal Anthropological Institute, EarlyView.The Eastern Mediterranean lies directly on the principal migration route for human groups dispersing across Africa, Europe, and Asia. It also encompasses the Balkans, where fauna and flora, as well as hominin populations, are thought to have persisted through glacial periods.

Integrative Zoology, EarlyView.• The Trans‐Mexican Volcanic Belt (TMVB) separates the Nearctic from the Neotropics. • TMVB's geology influenced diversification and distribution of endemic goodeid fishes. • Six neartic Gyrodactylus species infect goodeids within and north of the TMVB.

Methods in Ecology and Evolution, EarlyView.Abstract Detecting environmental DNA (eDNA) from rare or low‐abundance aquatic species remains a major challenge, particularly when it is highly degraded, present at low concentrations, and dominated by DNA from non‐target taxa. These challenges are further amplified in sedimentary ancient DNA (sedaDNA) studies, where thousands of years can degrade ...

Archaeometry, EarlyView.ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.
