Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

The evolutionary modifications of a GoLoco motif in the AGS protein facilitate micromere formation in the sea urchin embryo

eLife
The evolutionary introduction of asymmetric cell division (ACD) into the developmental program facilitates the formation of a new cell type, contributing to developmental diversity and, eventually, species diversification. The micromere of the sea urchin

Species and Abundance of Sea Urchins (Diadematidae) on Different Environmental Pressure Conditions

Journal of Tropical Life Science, 2017
Genetic diversity of sea urchin are very high; there are no two organisms of the same species that are exactly alike. Dense aggregation of sea urchin is responsible for the destruction of marine algae communities on coral reef ecosystem.

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Voices From the Coast: Stakeholder Participation and Perception on Creating a Marine Protected Area

Business Strategy and the Environment, EarlyView.
ABSTRACT This study explores participatory processes in the context of marine conservation, with a specific focus on recent initiatives undertaken by the Apulia region in Italy to establish a new Marine Protected Area (MPA). Employing a qualitative cross‐sectional methodology, the study investigates how local communities perceive and engage with the ...

MICROPAPILLAE IN SEA URCHIN EGGS* [PDF]

Development, Growth and Differentiation, 1976
Sea urchin eggs fixed in a glutaraldehyde-calcium chloride mixture have "micropapillae" with a dense content. If these structures are real, they are likely to be sites where a fusion with the spermatozoon can take place. It is possible however that they represent some kind of preparation artefact without a structural counterpart in the living state.

Sustainability Certifications as Strategic Tools: Environmental Accountability, Institutional Robustness and Global Convergence

Business Strategy and the Environment, EarlyView.
ABSTRACT Sustainability certifications are increasingly used as strategic tools to advance accountability for environmental sustainability. This study addresses the challenge of fragmented national certification standards by proposing and applying a replicable method to assess the structural robustness and convergence of industry‐specific ...

Micromechanics of Sea Urchin Spines

PLoS ONE, 2012
The endoskeletal structure of the Sea Urchin, Centrostephanus rodgersii, has numerous long spines whose known functions include locomotion, sensing, and protection against predators. These spines have a remarkable internal microstructure and are made of single-crystal calcite.
