Raman Signature of the Wings of the Globe Skimmer Dragonfly: Pantala flavescens

Journal of Raman Spectroscopy, EarlyView.
Raman spectroscopy is used to confirm the presence of aliphatic and aromatic hydrocarbons and related derivatives including aldehydes, halides, alcohols, acids, esters, and phenols on the wings of Pantala flavescens. The analysis indicates that wing‐surface lipid composition is largely consistent across the three main ecological zones in Ghana. Notably,

Aquatic and Littoral Successions in Various Post‐Mining Sites—Patterns and Possible Use in Ecological Restoration

Land Degradation &Development, EarlyView.
ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...

The first evidence of breeding by Crocothemis sanguinolenta and Zygonyx torridus (Odonata: Libellulidae) in Iran [PDF]

Journal of Insect Biodiversity and Systematics
For the first time, exuviae of Crocothemis sanguinolenta and Zygonyx torridus were collected from southern parts of Iran. Females of Z. torridus were also observed mating and ovipositing in two habitats.

Cryostratigraphy of Rhythmic Segregated Ice in Colluvium and Implications for Permafrost Slope Stability

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The amount and stratigraphic setting of ground ice in permafrost slopes is a key control on the style and magnitude of permafrost mass wasting. Understanding the spatial and stratigraphic variations in ground ice distribution on permafrost slopes is therefore a fundamental property in assessing the stability of permafrost hillslopes.

Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone

Journal of Field Robotics, EarlyView.
ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.
