The True Challenge of Giant Marine Reserves [PDF]

open access: yesScience, 2013
The News Focus story "Giant marine reserves pose vast challenges" (C. Pala, 8 February, p. [640][1]) discusses the potential role of large marine reserves in conserving pelagic species. We highlight three points that are misrepresented in the article.

Estimating Queen Conch (Strombus gigas) home ranges using acoustic telemetry: implications for the design of marine fishery reserves [PDF]

open access: yes, 2003
Marine reserves (MRs) may function as a vital tool in the conservation and management of marine resources if source populations are managed for the benefit of those downstream.

A review of the ecological effectiveness of subtidal marine reserves in Central California, Part I: Synopsis of scientific investigations [PDF]

open access: yes, 2004
Marine reserves, often referred to as no-take MPAs, are defined as areas within which human activities that can result in the removal or alteration of biotic and abiotic components of an ecosystem are prohibited or greatly restricted (NRC 2001 ...

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam

open access: yesAdvanced Engineering Materials, EarlyView.
Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

COASTAL-MARINE EXTRACTIVE RESERVES: REFLECTIONS ON THE PRE-IMPLEMENTATION STAGE [PDF]

open access: yesAmbiente & Sociedade, 2018
This article reflects on the process of institutionalization of Extractive Reserves, more specifically those located in a coastal-marine environment, in light of the concept of community-based co-management. The analysis focuses on the pre-implementation

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Rapid effects of marine reserves via larval dispersal. [PDF]

open access: yesPLoS ONE, 2009
Marine reserves have been advocated worldwide as conservation and fishery management tools. It is argued that they can protect ecosystems and also benefit fisheries via density-dependent spillover of adults and enhanced larval dispersal into fishing ...
