Misiones, Argentina, contains the largest remaining tract of Upper Paraná Atlantic Forest ecoregion; however, ~50% of native forest is unprotected and located in a mosaic of plantations, agriculture, and pastures. Existing protected areas are becoming increasingly isolated due to ongoing habitat modification. These factors, combined with lower than expected regional carnivore densities, emphasi...

Connecting isolated patches of habitat in fragmented landscapes with corridors is a popular conservation strategy. This strategy is also controversial in large part because of uncertainty about what characteristics of a species and its environment promote corridor use. In this article we address the question, For what types of species will populations benefit from corridors? We asked this quest...

We investigate the sensitivity of emissions corridors for the 21 century to various factors currently under debate in the climate change arena. Emissions corridors represent the range of admissible emissions futures that observe some predefined guardrails on the future development of the human-climate system. They are calculated on the conceptual and methodological basis of the tolerable window...

Summary Increasing population, expansion of urban areas and rapid urbanization are the main causes losing green spaces, which results in many environmental problems threatens quality life. Urban spaces great importance planning issues nowadays gain increasing popularity. It is realized that biological methodologies need to be used planning, otherwise life will more threatened. In order discover...

Conservation biologists recognize that a system of isolated protected areas will be necessary but insufficient to meet biodiversity objectives. Current approaches to connecting core conservation areas through corridors consider optimal corridor placement based on a single optimization goal: commonly, maximizing the movement for a target species across a network of protected areas. We show that ...

The fundamental organizing elements of the New Urbanism are the neighborhood, the district and the corridor. Neighborhoods are urbanized areas with a balanced mix of human activity; districts are areas dominated by a single activity; corridors are connectors and separators of neighborhoods and districts. A single neighborhood standing free in the landscape is a village. Cities and towns are mad...

In a large-scale experiment, we found that three habitat-restricted butterfly species reached higher densities in patches connected by corridors than in similar, isolated patches. We conducted our study in 27 equal-sized (1.64-ha) patches that varied in whether or not they were connected to another patch by a corridor. Patches and corridors were open, early-successional habitat that contrasted ...

Some believe orthodontics has undergone a “paradigm shift” to focus more on esthetics, with emphasis on the soft tissues surrounding the mouth. This web based study evaluated changes in attractiveness based on computerized variations of smile arcs and buccal corridors for male and female smiles judged by orthodontists and laypersons on a visual analog scale. The results indicate that both laype...
