Selection on male and female reproductive traits in a simultaneous hermaphrodite land snail [PDF]

, 2013
Classical sexual selection theory assumes that the reproductive success of females is limited by the resources available for egg production, while the reproductive success of males is determined by the number of mates (Bateman’s principle).

CONE SNAIL BIOLOGY, BIOPROSPECTING AND CONSERVATION [PDF]

, 2013
International audienceCone snails are predatory marine gastropods that prey on worms, molluscs and fish. The venoms of these animals are true pharmacological treasures, and with the recent approval of the first cone snail venom-derived drug, the pressure

Predatory and Defensive Strategies in Cone Snails

Toxins
Cone snails are carnivorous marine animals that prey on fish (piscivorous), worms (vermivorous), or other mollusks (molluscivorous). They produce a complex venom mostly made of disulfide-rich conotoxins and conopeptides in a compartmentalized venom gland.

Membrane lipid metabolism as a regulatory frontier in neural crest biology: Roles for sphingolipids, cholesterol, and lipid rafts

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are multipotent, migratory stem‐like cells essential for vertebrate development that contribute broadly to many tissues including the craniofacial skeleton, peripheral nervous system, and pigment‐producing cells. Their development progresses through phases of induction, specification, delamination, migration, and ...

The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Biochemistry of Cone Snail toxin activation [PDF]

, 2013
posterCone snails use venom to capture prey for food and for defense against predators. The venom is composed of over 100 active peptides that target specific receptors in the nervous system.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Holocene shoreline displacement and the impact of the Storegga tsunami on Hinnøya, northern Norway

Boreas, EarlyView.
The Holocene relative sea‐level (RSL) history of Norway's largest island, Hinnøya, has been investigated in detail, using sediment records from 25 isolation basins. The sediments were analysed for macrofossil and phytoplankton content, which served as the basis for identifying marine–lacustrine transitions, that is isolation contacts. Terrestrial plant
