Los moluscos y la contaminación: Una revisión Mollusks and pollution: A review

Revista Mexicana de Biodiversidad, 2007
Los moluscos son un grupo megadiverso que en cuanto a número de especies sólo lo sobrepasan los insectos y los nemátodos; no así en cuanto a la diversidad de hábitos de vida y hábitats que ocupan. Las especies de moluscos se encuentran en los desiertos y

Widespread complex enameloid microstructure in teeth and rostral denticles of Cretaceous sclerorhynchoid skates (Rajiformes: †Sclerorhynchoidei)

Journal of Anatomy, EarlyView.
This article demonstrates that the teeth and rostral denticles of an extinct clade of sawfish‐like skates display an extremely derived enameloid microstructure, similar to what is known among sharks. The presence of tooth‐like enameloid microstructure in dermal denticles opens new perspectives about the origins and development of chondrichthyan ...

Restoration ecology in conflict along the Colorado front range

Restoration Ecology, EarlyView.
Abstract Introduction Cheatgrass (Bromus tectorum) is a challenge to restoration in western North America. It attracts the attention of academic and government research scientists, weed managers, and chemical companies. Attempts to control it cause conflicts among these groups.

The effects of bioturbation on porewater chemistry and early marine diagenesis: Evidence from a modern intertidal zone in Abu Dhabi, U.A.E.

Sedimentology, EarlyView.
ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

[Viruses of bivalve shellfish].

Virologie (Montrouge, France), 2006
Les mollusques bivalves sont des filtreurs et de ce fait ils peuvent accumuler dans leurs tissus des virus d'origine anthropique. Par ailleurs, des mortalités ont été rapportées chez les bivalves en association à la détection de virus apparentés à différentes familles. Ainsi, des mortalités massives de l'huître portugaise, Crassostrea angulata, ont été

Recognition of fossil keratose sponges in carbonates using petrographic and machine‐learning classification

Sedimentology, EarlyView.
ABSTRACT Filamentous, anastomosing spar‐filled networks in Phanerozoic carbonates have been interpreted as the mineralised remains of keratose (non‐spiculate) sponges, yet their recognition remains contested because fabrics of broadly similar appearance may arise from microbial, diagenetic or physical processes. This study combines direct fossil–modern

Diagenetic controls on porosity evolution and pore type organisation in microporous carbonate rocks: Evidence for mesogenetic porosity formation

Sedimentology, EarlyView.
ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin

Sedimentology, EarlyView.
ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.

Contourite erosional and depositional features of the Maastrichtian chalk on Jasmund peninsula (Rügen island, NE Germany)

Sedimentology, EarlyView.
ABSTRACT Seismic‐scale features such as deeply incised submarine valleys and mounded drifts together with ichnological features indicative of discontinuous sedimentation and erosional episodes have recently been documented from the Upper Cretaceous chalk in the southern Baltic Sea area.

Life‐Stage–Specific Hematological Profiles in Yellow Mealworm Beetles (Tenebrio molitor): Reference Intervals and Hemocyte Characterization

Veterinary Clinical Pathology, EarlyView.
ABSTRACT Background The edible insect industry, driven by the nutritional and environmental benefits of mealworms, faces increasing challenges from pathogens affecting Tenebrio molitor farming systems. Hemocyte‐based health assessments could provide valuable diagnostic insights, yet standardized hemolymph processing protocols and hematological ...
