Managing the Threat of Subsidized Predators for a Threatened Shorebird

Animal Conservation, EarlyView.
Subsidized predators—native predators that have become more common due to human activities—challenge the persistence of many at‐risk prey species and require creative solutions beyond lethal predator control. In an 8‐year study, we placed small wire cages over western snowy plover nests that allow passage of plovers, but not their predators, and ...

Morfometría de Sanguinolaria cruenta (Bivalvia: Psammobidae) en playa Tucacas, Falcón, Venezuela

Revista de Biología Tropical, 2001
Se colectaron 312 conchas de S. cruenta con su ligamento en Playa Tucacas, Edo. Falcón, en mayo de 1999. A cada ejemplar se le midió: longitud antero-posterior, altura total, ancho, longitud anterior, altura dorsal, área de la valva y su peso.

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Oxidative stress and bivalves: a proteomic approach [PDF]

Invertebrate Survival Journal, 2008
Bivalves are of major importance in aquatic ecology, aquaculture, are widely used as sentinel species in environmental toxicology and show remarkable plasticity to molecular oxygen.

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

Archaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Neural Networks and Multivariate Analysis Based on Geochemical Data to Determine Stone Provenance From Ancient Calabrian Quarries (Southern Italy)

Archaeometry, EarlyView.
ABSTRACT This study shows an innovative approach to determine the origin of some Calabrian rocks quarried used in ancient times. Twenty‐five quarries, distributed in all the Calabrian provinces (Southern Italy), were studied and sampled. Ten samples were taken from each quarry, for a total of 250 samples.

Abundancia de juveniles y crecimiento de Pinna carnea (Mytiloida: Pinnacea) en cultivo suspendido

Revista de Biología Tropical, 2000
Se evaluó la abundancia de juveniles de Pinna carnea, el crecimiento y su relación con factores ambientales en cultivo suspendido en Turpialito, Golfo de Cariaco, Venezuela. La abundancia se determinó usando colectores suspendidos a 8 m de profundidad en

HSP expression in bivalves

Invertebrate Survival Journal, 2008
One of the molecular responses which mostly contribute to the physiological plasticity of bivalves is the heat shock response mediated by heat shock proteins (HSP). Variations of HSP response were observed under environmental conditions, correlated with differences in environmental temperature and degree of heterogeneity across geographic thermal ...

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
