Survey of orchidaceae from the State of Sergipe, Brazil Biota Neotropica
Monteiro,Silvana Helena Nascimento; Carregosa,Tamires; Santos,Luiz Aquino Silva; Nascimento Júnior,José Elvino do; Prata,Ana Paula do Nascimento.
The state of Sergipe, located in the Northeast Region of Brazil, covers an area of 21,994 km² and is the smallest state in the country. The vegetation of this region is predominantly caatinga, but there are also mangroves, dunes, restinga, fragments of original Atlantic Forest (which are intermingled with pastures, secondary growth, and agricultural land) and cerrado. During intensive fieldwork in Sergipe, we observed various Orchidaceae species that had not been recorded for the state, which made it necessary to update the list of species for this region. Within the state, the family is represented by 63 species and 34 genera, of which Habenaria (10 spp.) Epidendrum (4 spp.) and Encyclia (4 spp.) are highlights. Orchidaceae species from this region are...

The Effects of Human Socioeconomic Status and Cultural Characteristics on Urban Patterns of Biodiversity Ecology and Society
Kinzig, Ann P; Arizona State University; Ann.Kinzig@asu.edu; Warren, Paige; ; Paige.Warren@asu.edu; Martin, Chris; ; Chris.Martin@asu.edu; Hope, Diane; ; Diane.Hope@asu.edu; Katti, Madhusudan; ; mkatti@asu.edu.
We present evidence that there can be substantial variation in species richness in residential areas differing in their socioeconomic and cultural characteristics. Many analyses of the impacts of urbanization on biodiversity rely on traditional “urban-to-rural” gradient measures, such as distance from urban center or population density, and thus can fail to account for the ways in which human socioeconomic and cultural characteristics are shaping the human–environment interaction and ecological outcomes. This influence of residential values and economic resources on biodiversity within the urban matrix has implications for human quality of life, for urban conservation strategies, and for urban planning.
