Description

The WR300N device can take an existing 802.11n wireless signal, repeat and send it to a longer range where it is too far away for the router or access point to reach. It eliminates the cable wires while providing the same reliable network connection...

Features

• Receives weak wireless signals and extends the signal range to greater distances eliminating wireless dead spots
• Create a wireless network by connecting the device to a wired router/cable modem or DSL modem
• Receives wireless signal from your home wireless network and convert to wired Ethernet connections for non wireless devices such as internet ready
• Supports wireless 802.11b/g/n standards with one 10/100Base-T Ethernet port
• HDTV's, gaming consoles (PS3) and internet ready blue ray players

CALE-SE - A MPB e a Ditadura Militar parte da análise de um dos períodos que mais marcaram a História do Brasil e a produção cultural do país àquela época. Apontando as letras das canções compostas nos anos mais duros da ditadura (1964 a 1974), reforça a ideia de que a música serviu – e serve - como uma importante ferramenta de comunicação, carregando mensagens (as mais variadas possíveis) com as palavras e frases que formam suas letras...

Description

Human impacts are dramatically altering our natural ecosystems but the exact repercussions on ecological sustainability and function remain unclear. As a result, food web theory has experienced a proliferation of research seeking to address these critical areas...

Description

The major subdisciplines of ecology--population ecology, community ecology, ecosystem ecology, and evolutionary ecology--have diverged increasingly in recent decades. What is critically needed today is an integrated, real-world approach to ecology that reflects the interdependency of biodiversity and ecosystem functioning...

Description

This book provides a first synthetic view of an emerging area of ecology and biogeography, linking individual- and population-level processes to geographic distributions and biodiversity patterns. Problems in evolutionary ecology, macroecology, and biogeography are illuminated by this integrative view...

Description

Despite its supreme importance and the threat of its global crash, biodiversity remains poorly understood both empirically and theoretically. This ambitious book presents a new, general neutral theory to explain the origin, maintenance, and loss of biodiversity in a biogeographic context...

Description

An ecosystem's complexity develops from the vast numbers of species interacting in ecological communities. The nature of these interactions, in turn, depends on environmental context. How do these components together influence an ecosystem's behavior as a whole? Can ecologists resolve an ecosystem's complexity in order to predict its response to disturbances? Resolving Ecosystem Complexity develops a framework for anticipating the ways environmental context determines the functioning of ecosystems...

Description

Understanding the mechanisms driving biological diversity remains a central problem in ecology and evolutionary biology. Traditional explanations assume that differences in selection pressures lead to different adaptations in geographically separated locations...
