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.

Modeling Skin Mark Temporal Variations to Estimate the Sex of Delphinids with Low Sexual Dimorphism: Implications for Management and Conservation

Integrative Zoology, EarlyView.
This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation

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 ...

Uncoupled Histories in the Largest Continental Arc of North America: Goodeid Fishes and Their Gyrodactylid Parasites Influenced Differently by the Trans‐Mexican Volcanic Belt

Integrative Zoology, EarlyView.
• The Trans‐Mexican Volcanic Belt (TMVB) separates the Nearctic from the Neotropics. • TMVB's geology influenced diversification and distribution of endemic goodeid fishes. • Six neartic Gyrodactylus species infect goodeids within and north of the TMVB.

Late Iron Age and Early Roman Brooches From the Lower Rhine Area: Provenance of the Metal Supply Traced Through Lead Isotopes

Archaeometry, EarlyView.
ABSTRACT Geochemical analysis of five brooch types from the Lower Rhine area dated to the last century bc and first century ad is used to constrain resource use, exchange and mobility. Lead isotope ratios demonstrate an Iberian provenance for copper in bronze Late Iron Age brooches.

Effect of contracted river on tidal bore in Qiantang Estuary

Shui kexue jinzhan
Since the late 1960s, the Qiantang Estuary has been narrowed on a large scale, significantly changing the water-sediment dynamics, riverbed evolution and their interaction processes.

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.
