Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats

Limnology and Oceanography: Methods, EarlyView.
Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.

Towards the Systematization of the Japanese Maritime Traffic Law

Journal of Advanced Computational Intelligence and Intelligent Informatics, 1997
The existing laws and regulations function as a social engineering system in the vertically-structured society. However it is difficult for nonprofessionals to understand the legal knowledge which has, abstract expressions for provisions, the hierarchy structures of legal systems, the richness of legal text, the deficiency of laws, and so on.

Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.

Sexual reproduction in invasive Japanese knotweed (Reynoutria japonica) in south Sweden

Nordic Journal of Botany, EarlyView.
To understand the potential for northward expansion of knotweeds into currently uninvaded regions, it is crucial to assess the potential for sexual reproduction alongside the ongoing vegetative spread. For that reason, we tested viability in Reynoutria japonica seeds in south Sweden, a region where viable seeds had not been previously reported ...

A process‐based social‐ecological systems framework for studying the effects of human recreation on wildlife

People and Nature, EarlyView.
Abstract Understanding the effects of human recreation on wildlife is fundamental for effective management and coexistence, where natural landscapes increasingly serve a dual purpose: protecting biodiversity while providing recreational opportunities. Social‐ecological systems frameworks, which acknowledge the reciprocal links between people and nature,
