300 Years of Degradation in Wales Estuaries and Coasts

Natural Resources Forum, EarlyView.
ABSTRACT The world's oceans are in a severe state of degradation, yet our understanding of that degradation is often based on changes observed only in the past 20–50 years. This narrow view leads to marine conservation efforts that aim to preserve already degraded ecosystems, shaped by shifted ecological baselines.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Benthic habitat mapping using high-Resolution image mosaicking

, 2012
Benthic ecosystems of most continental shelves, slopes and seamounts are altered by the use of bottom-contact fishing gears and other human activities, such as hydrocarbon drilling and seabed mining.

First Insights on Photoreceptor Organ Ultrastructure in Marine Chaetonotida (Gastrotricha): Species of Xenotrichula and Draculiciteria (Xenotrichulidae)

Acta Zoologica, EarlyView.
ABSTRACT Marine gastrotrichs inhabit sediments with limited available light, yet evidence suggests that photoreceptor organs are present throughout the phylum Gastrotricha. Here, we confirm this proposition with ultrastructural descriptions of photoreceptive organs in two species of Xenotrichulidae (Order Chaetonotida) that lack pigmented ocelli ...

Benthic habitat mapping for the nearshore ecological monitoring of Dokdo (Dok island) in the East Sea (Sea of Japan)

, 2016
The Dokdo (do means an island) volcano comprises two main islets (Seo-do and Dong-do) and the associated submerged volcanic edifice in the Ulleung Basin, the East Sea. We have been obtained the detailed bathymetry data using multibeam echosounder for the

Chironomid‐based summer temperature reconstruction of the Eemian–Weichselian transition at Lichtenberg, northern Germany

Boreas, EarlyView.
Understanding the temperature variability of past interglacial cycles is essential to predict future climates. We present a new summer temperature reconstruction, based on the subfossil chironomid record from a small palaeolake adjacent to the Middle Palaeolithic site of Lichtenberg, northern Germany. The record spans from the Saalian late glacial over

Taxonomic and functional diversity of benthic foraminifera as a promising proxy for tidewater glacier retreat

Boreas, EarlyView.
Ice sheets and glaciers globally are losing mass at increasing rates, with the strongest changes occurring at tidewater glaciers. These are rapidly retreating and often transitioning to land‐terminating with implications for sea level change and ecosystem functioning.
