Reliable Refuge: Two Sky Island Scorpion Species Select Larger, Thermally Stable Retreat Sites. [PDF]

open access: yesPLoS ONE, 2016
Sky island scorpions shelter under rocks and other surface debris, but, as with other scorpions, it is unclear whether these species select retreat sites randomly.

Anemomenotatic orientation in beetles and scorpions [PDF]

open access: yes, 1972
Orientation, by beetles and scorpions, according to wind direction and force are analyzed. Major efforts were made to determine: (1) which physical qualities of the air current influence anemomenotaxis, (2) which physiological mechanism is responsible ...

Periacineta mexicana n. sp. (Ciliophora, Suctoria, Discophryida), Epizoic on Mexican Backswimmers of the Genus Buenoa (Insecta, Hemiptera, Notonectidae) [PDF]

open access: yes, 2010
A new species of suctorian in the genus Periacineta, epibiotic on aquatic bugs (Hemiptera, Heteroptera, Nepomorpha), is described on the basis of morphological characteristics of the cell body, lorica, tentacular placement, and stalk, and its 18S rRNA ...

Sculpting the Future of Bone: The Evolution of Absorbable Materials in Orthopedics

open access: yesAdvanced Materials, EarlyView.
This review summarizes the current status of polymeric, ceramic, and metallic absorbable materials in orthopedic applications, and highlights several innovative strategies designed to enhance mechanical performance, control degradation, and promote bioactivity. We also discuss the progress and translational potential of absorbable materials in treating

Tearing Out the Income Tax by the (Grass)Roots [PDF]

open access: yes, 2014
Landscapes are increasingly fragmented, and conservation programs have started to look at network approaches for maintaining populations at a larger scale. We present an agent-based model of predator–prey dynamics where the agents (i.e.

A novel record of aardwolf Proteles cristata feeding behaviour [PDF]

open access: yes, 2013
Terrestrial members of the order Carnivora show great variation in their diet; some specialising on vertebrates, invertebrates, or plant matter, whereas others are omnivores or scavengers (Bekoff et al, 1984).

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

open access: yesThe Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

Embryotoxicity following repetitive maternal exposure to scorpion venom

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2012
Although it is a frequent accident in a few countries, scorpion envenomation during pregnancy remains scarcely studied. In the present study, the effects of repetitive maternal exposure to Buthus occitanus tunetanus venom are investigated and its ...

Does a Cadillac engine need a biological and phylogenetic explanation? [PDF]

open access: yes, 2016
In this text we briefly explore whether ridiculing material objects like a ‘Cadillac engine’, a ‘desk’, ‘gold bars in a vault’ as reduction ad absurdum in ‘dialectical duels’ or as a metaphor for teaching evolution is really phylogenetically justified,
