“…The BRT model could be used to predict a potential change in stream biological condition based on anticipated changes in population density and development in stream buffer areas. Understanding such relationships is essential to planning efforts for preservation of biodiversity in highly urbanized areas, such as Southern Coastal California (Shearer et al, 2006) and elsewhere (Baldwin et al, 2009;Beardsley et al, 2009;Hermoso et al, 2012). In addition, the BRT model could be used to target new regional bioassessments according to predicted biological condition.…”

“…They do not initially alter the overall nature of the landscape, but can become access corridors for poachers, invasive species, and squatters (Gallice, Larrea‐Gallegos, & Vázquez‐Rowe, ; Laurance & Arrea, ). In forested areas where vacation homes are developed, the natural beauty of the landscape appears intact and is highly desired; however, the introduction of vacation homes initiates cryptic change that erodes the natural diversity of the landscape over time (Baldwin, Trombulak, & Baldwin, ; Warren et al, ). Fire control, for example, alters species assemblages, with fire intolerant species crowding out fire‐resistant species.…”

“…Fire control, for example, alters species assemblages, with fire intolerant species crowding out fire-resistant species. Weeds can enter and spread along roads and trails, top predators are suppressed to protect human life, dispersal patterns are disrupted, and novel predation from pets reduces song-bird and small mammal populations(Baldwin et al, 2009;Loss & Marra, 2017;Warren et al, 2015). Eventually, catastrophic change can occur as a result of massive wildfires or pest outbreaks enabled by vegetation crowding and expansion of fire-or pest-intolerant species.Tropical deforestation is a major form of land transformation in recent years due to economic and population growth within tropical nations(Lewis, Edwards, & Galbraith, 2015).…”

Because of human action, the Earth has entered an era where profound changes in the global environment are creating novel conditions that will be discernable far into the future. One consequence may be a large reduction of the Earth's biodiversity, potentially representing a sixth mass extinction. With effective stewardship, the global change drivers that threaten the Earth's biota could be alleviated, but this requires clear understanding of the drivers, their interactions, and how they impact ecological communities. This review identifies 10 anthropogenic global change drivers and discusses how six of the drivers (atmospheric CO2 enrichment, climate change, land transformation, species exploitation, exotic species invasions, eutrophication) impact Earth's biodiversity. Driver impacts on a particular species could be positive or negative. In either case, they initiate secondary responses that cascade along ecological lines of connection and in doing so magnify the initial impact. The unique nature of the threat to the Earth's biodiversity is not simply due to the magnitude of each driver, but due to the speed of change, the novelty of the drivers, and their interactions. Emphasizing one driver, notably climate change, is problematic because the other global change drivers also degrade biodiversity and together threaten the stability of the biosphere. As the main academic journal addressing global change effects on living systems, GCB is well positioned to provide leadership in solving the global change challenge. If humanity cannot meet the challenge, then GCB is positioned to serve as a leading chronicle of the sixth mass extinction to occur on planet Earth.

“…Besides, mining adversely affect local water quality, soil structure, and vegetation (Kondolf 1997). In addition, secondary homes, despite smaller spatial extent of current occurrence functions as development nodes in future land development (Baldwin et al 2009). Therefore, certain minor landuses can have a significant impact on biodiversity and natural ecosystems disproportionate to their spatial extent.…”

Identification of regions that warrant conservation attention is a top priority among global environmental concerns. Conventionally, this objective was achieved via recognizing natural landscapes based on the number of IUCN Red Listed species, percentage of endemism and species diversity. A recent innovation in conservation biology is the use of GIS-based threat analysis models to identify key areas of conservation importance. Compared with GAP Analysis, which only identifies biodiversity-rich unprotected lands, threat analysis serves as a rigorous tool in conservation planning which specifically recognizes threats and habitat suitability to different taxa based on a spatially-explicit analysis. Threat analysis is a highly flexible process which involves building up a model with multiple independent (without autocorrelations) variables that both positively and negatively affect distribution and population persistence of a concerned species. Parameters include rate of land-use change, population density, population growth rate, land management regimes, protection status, habitat suitability and land stewardship. Threat analysis models can be used to understand the current status of a particular species (or a community) and can be used to project future trends about the species under consideration. This publication provides an overview of uses of GIS-based threat analyses in conservation biology and provides insights on the limitations of these models and the directions that should be taken in future.
