Mechanical Properties and Microscopic Mechanism of Coral Sand-Cement Mortar

Advances in Materials Science and Engineering, 2020
The workability and mechanical performance of coral sand-cement mortar (coral mortar, for short) and the modification effects of mineral admixtures on the coral mortar were studied in this paper.

Widespread Bomb Fishing in Indo‐Pacific Archipelago Revealed Through Machine Learning Accelerated Passive Acoustic Monitoring

Remote Sensing in Ecology and Conservation, EarlyView.
AI‐accelerated passive acoustic monitoring reveals extensive bomb fishing within the Spermonde Archipelago, with annual incidents numbering in the thousands. ABSTRACT Bomb fishing is recognised as the most destructive fishing practice that can be performed in our oceans.

Regional Sustainable Economic Development in the Caribbean? A Discursive Inquiry

Sustainable Development, EarlyView.
ABSTRACT The Caribbean region is governed by several regional bodies. Among the more important organizations for small island states, where coral reefs and ocean conservation are paramount, is the Caribbean Community (CARICOM). Currently, the region is going through critical environmental changes that bring important vulnerabilities.

Native habitat affinities predict fish invasions with post‐invasion habitat shifts

Journal of Animal Ecology, EarlyView.
Initial invasion success is gated by native pre‐adaptations, but post‐invasion establishment is characterized by habitat shifts. We demonstrate that forecasting risk based solely on native niches severely underestimates future ecological impacts, and we provide an empirically validated watchlist of future invaders.

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.

Submerged geomorphic record of Quaternary palaeoshorelines: terraces and clinothems along a shelf‐edge in the Žirje Archipelago, Adriatic Sea

Boreas, EarlyView.
Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

‘I like to dance with the flowers!’: Exploring the possibilities for biodiverse futures in an urban forest school

Children &Society, EarlyView.
Abstract This article explores the ways in which ‘forest school’, an educational approach where children engage in creative and play based activities in a ‘natural’ environment, can contribute towards Sustainable Development Goal 15 (SDG 15) by promoting sustainable use of terrestrial ecosystems and by helping address biodiversity loss. Drawing on data

Estimating the total mortality of seabirds following a marine heat wave

Conservation Biology, EarlyView.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Risks of concealing environmental degradation

Conservation Biology, EarlyView.
Abstract Current practice seeks to conceal the visual impact of land‐use change (i.e., development). Six percent of development impact assessments in Australia and 14% of the World Bank's assessments recommend visual impact mitigation. This mitigation results in, for example, vegetated buffer strips alongside cleared agricultural areas and earthen ...

Research on the penetration characteristics of coral sand based on a visco-hypoplastic constitutive model

Case Studies in Construction Materials
This study investigates the penetration characteristics of coral sand based on hypoplasticity theory. The Gudehus-Bauer (GB) hypoplastic constitutive model was optimized by modifying the particle hardness parameter to incorporate strain rate effects ...
