Influence of waves and horseshoe crab spawning on beach morphology and sediment grain-size characteristics on a sandy estuarine beach

The effects of wave action and horseshoe crab spawning on the topography and grain-size characteristics on the foreshore of an estuarine sand beach in Delaware Bay, New Jersey, USA were evaluated using data collected over six consecutive high tides. Data were gathered inside and outside a 25 m long exclosure constructed to create a control area free of disturbance by crabs. The density of crabs...

Lines Underground: Exploring and Mapping Venezuela's Cave Environment

How do the lines on a map come into being? What stories do they tell? These questions are examined in the context of cave exploration and mapping in Venezuela. Ethnographic analysis focuses on mapping in the field, the translation of notes into final maps, and discourses surrounding these practices. The lines that cave surveyors sketch in field books while traversing underground passages reveal...

Global diversity patterns in sandy beach macrofauna: a biogeographic analysis

Unlike the advances generated on land, the knowledge of global diversity patterns in marine ecosystems is limited to a small number of studies. For sandy beaches, which dominate the world's ocean shores, previous meta-analyses highlighted the role of beach morphodynamics in explaining species richness patterns. Oceanographic variables and historical processes have not been considered, even thou...

Correction: Environmental Control on Fish and Macrocrustacean Spring Community-Structure, on an Intertidal Sandy Beach

The inter-annual variability of the fish and macrocrustacean spring community on an intertidal sandy beach near the Canche estuary (North of France) was studied from 2000 to 2013 based on weekly spring sampling over an 11-year period. Twenty-eight species representing 21 families were collected during the course of the study. The community was dominated by a few abundant species accounting for ...

Golden opportunities: A horizon scan to expand sandy beach ecology

Robust ecological paradigms and theories should, ideally, hold across several ecosystems. Yet, limited testing of generalities has occurred in some habitats despite these habitats offering unique features to make them good model systems for experiments. We contend this is the case for the ocean-exposed sandy beaches. Beaches have several distinctive traits, including extreme malleability of hab...
