Influence of coral mucus on nutrient fluxes in carbonate sands [PDF]

open access: yesMarine Ecology Progress Series, 2005
Mucus release by hard corals of the genus Acropora under submersed and naturally occurring air exposure was quantified at Heron Island/Great Barrier Reef. These measurements were conducted with beaker and in situ container incubation techniques. Mucus release rates for A. mille- pora, normalized to the coral surface area, were 10 ± 5 mg C and 1.3 ± 0.8

300 Years of Degradation in Wales Estuaries and Coasts

open access: yesNatural 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.

Resonant column tests on maximum shear modulus and damping ratio of coral sand

open access: yesYantu gongcheng xuebao, 2020
The resonant column tests on the effects of relative density and confining pressure on the maximum modulus and damping ratio of coral sand in South China Sea under small strain are performed.

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

open access: yesBoreas, 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 ...

Dynamic behavior of geogrid-reinforced coral sand with different consolidation stress ratios

open access: yes
Civil engineering structures built on coral sand foundations in the Sea experience dynamic anisotropic stresses rather than isotropic stress. A series of undrained dynamic tests were conducted on coral sand to investigate the effect of consolidation ...

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

open access: yesChildren &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

open access: yesConservation 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.

Particle breakage in triaxial shear of a coral sand

open access: yesSoils and Foundations, 2018
This paper presents a laboratory experimental study to comprehensively investigate the characteristics of particle breakage using numerous triaxial tests on a coral sand. Coral is a highly crushable granular material which fills the gaps between more crushable and less crushable granular materials.

Risks of concealing environmental degradation

open access: yesConservation 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 ...

Impacts of Ocean Acidification on Reproduction and Early Life Development in Marine Teleost Fish—A Synthesis

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Ocean acidification (OA) remains a major and underexplored threat to marine fishes, particularly regarding reproductive physiology and early life stages (ELS). Although research over the past 15 years has documented diverse OA effects, substantial knowledge gaps persist.
