Efecto acumulativo de agentes estresantes múltiples sobre  los corales hermatípicos de la región noroccidental de Cuba
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: González Díaz, S. P.
En las últimas décadas ha ocurrido un deterioro acelerado de los arrecifes de coral debido al  efecto sinérgico de impactos naturales y antrópicos. En consecuencia, el objetivo de la tesis  es evaluar los efectos acumulativos producidos por agentes estresantes múltiples y que  impactan de forma simultánea los corales hermatípicos. Para ello se estimaron indicadores  ecológicos en los niveles de comunidad y población. Los resultados obtenidos en esta  investigación evidencian cambios en la estructura de las comunidades de corales que se  asocian con el impacto antrópico directo existente a lo largo de la costa noroccidental de  Cuba y que disminuye en la dirección este-oeste. Los indicadores ecológicos referidos a las  tallas de los corales, muestran...

Interactions between distant places are increasingly widespread and influential, often leading to unexpected outcomes with profound implications for sustainability. Numerous sustainability studies have been conducted within a particular place with little attention to the impacts of distant interactions on sustainability in multiple places. Although distant forces have been studied, they are usually treated as exogenous variables and feedbacks have rarely been considered. To understand and integrate various distant interactions better, we propose an integrated framework based on telecoupling, an umbrella concept that refers to socioeconomic and environmental interactions over distances. The concept of telecoupling is a logical extension of research on...

Homeland Security and the Rules of International Trade
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kerr,   William A.
International trade law is very clear: national security concerns take precedent over any commitments in trade agreements. In response to the terrorist attacks in New York and Washington on September 11, 2001, the United States and other countries have been putting in place new anti-terrorist measures, many of which will act to inhibit international trade. As with any measure that inhibits international trade, these new measures will provide an economic benefit to domestic vested interests in importing countries. Guarding against the possibility of terrorist acts is by nature a speculative activity, and it is difficult to refute the need for the anti-terrorist measures put in place by governments. As a result, trading partners may be frustrated by what...
