Densidade urbana e urbanismo paramétrico

Revista de Morfologia Urbana, 2020
O desconhecimento e a pouca aplicação de ferramentas computacionais para visualizar índices urbanísticos dificultam que planejadores e gestores possam compreender os possíveis impactos desses índices na forma e ocupação do solo urbano e, consequentemente, produzem cidades que não atendem aos princípios de sustentabilidade e urbanidade.

Arquitectura y densidad

Revista de Arquitectura, 2019
La proliferación de edificaciones en altura en las comunas centrales de la ciudad de Santiago ha ido acompañada de una serie de debates sobre su efecto y su regulación. El texto recoge algunas controversias tempranas y recientes de esta tipología para trazar la forma cómo la densidad ha ido adquiriendo un sentido proyectual dentro de esta y sirviendo ...

Patrones de reclutamiento en cuatro especies de Physaria (Brassicaceae): implicancias para el mantenimiento de la densidad en poblaciones silvestres y en cultivo [PDF]

, 2016
En zonas áridas, el reclutamiento de nuevos individuos es un proceso crítico que determina la viabilidad poblacional, el potencial de invasión de plantas alóctonas y el éxito en el establecimiento de cultivos.

Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

Conservation Biology, EarlyView.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Lessons from an eradication under multiple constraints of an island rat population of record density

Conservation Biology, EarlyView.
Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

Role of freshwater availability and terrestrial land‐cover change in the distribution of a declining, terrestrial, insectivorous bird

Conservation Biology, EarlyView.
Abstract Insectivorous, Afro‐Palearctic migrant birds provide cross‐border ecosystem services, but many are declining rapidly. The complex life cycle of migrant birds makes their conservation difficult, but understanding where they spend time during the breeding season can help indicate where those actions will be most effective.
