Perspectives on the Effect of Incubation Temperature on Pine Snake Hatchlings

open access: yesEthology, EarlyView.
Effect of timing of egg‐laying and incubation temperature on the possible phenology of events for early egg‐laying females (laying June 15, the earliest laying date), the mid‐laying date (July 4), and late egg‐laying females (July 17, the latest egg‐laying date). Based on data from many papers.

Locating nests of endangered bumble bees: Lessons from field trials in northern Germany

open access: yesInsect Conservation and Diversity, EarlyView.
Tracking bumble bees to find their nests using coloured strips of paper stuck to their thorax proved to be the most suitable method, while radio transponders were too heavy. Tracking times of up to 2 h and distances of up to 800 m were achieved with strips of pink craft tissue paper.

First occurrences of Trionychidae (Testudines, Cryptodira) from the Miocene of Poland: Detailed cranial anatomy and biogeographic implications

open access: yesJournal of Anatomy, EarlyView.
Fossil finds from three Middle Miocene sites in Poland reveal the northernmost known presence of trionychid turtles in Europe, tentatively identified as Trionyx cf. vindobonensis, suggesting a warmer climate that supported thermophilic species in Central Europe during this period. Abstract Modern trionychids (Testudines, Cryptodira) have a pan‐tropical

Ips acuminatus (Gyllenhal) in the Czech Republic: Flight dynamics and adult population structure

open access: yesPhysiological Entomology, EarlyView.
Ips acuminatus exhibits a univoltine life cycle in Central Europe and no full second generation in midsummer. The sex ratio shifts from male‐biased in spring to slightly female‐biased with the season, with over 90% of females mated. Among the pheromone lures tested, the ACP was most attractive, and combining ACP and PH lures could be used for effective
