Persistence-based area prioritization for conservation: Applying occupancy and habitat threats and risks analyses Persistence-based area prioritization for conservation: Applying occupancy and habitat threats and risks analyses
Effective habitat conservation is predicated on maintaining high levels or increasing local persistence probability of the species it purports to protect. Thus, methodological approaches that improve the inferential value of local persistence are of utmost value to guide conservation planning as they inform area selection processes. Herein we used the painted bunting Passerina ciris, a...

Toward a resilience-based conservation strategy for wetlands in Puerto Rico: Meeting challenges posed by environmental change Toward a resilience-based conservation strategy for wetlands in Puerto Rico: Meeting challenges posed by environmental change
Designing conservation strategies in human-dominated landscapes is challenging, owing to complex human-natural systems and evolving societal values. To meet this challenge, a robust, adaptive strategy should have a process for flexible implementation of incremental actions. We describe a hypothetical example for the Rio Grande de Arecibo watershed and coastal wetlands in Puerto Rico to...

Improving our understanding of demographic monitoring: avian breeding productivity in a tropical dry forest Improving our understanding of demographic monitoring: avian breeding productivity in a tropical dry forest
The ratio of juvenile to adult birds in mist-net samples is used to monitor avian productivity, but whether it is a “true” estimate of per capita productivity or an index proportional to productivity depends on whether capture probability is not age-dependent (true estimate) or age difference in capture probability is consistent among years (index). Better understanding of the processes...

Resurgence of specialized shade coffee cultivation: Effects on pollination services and quality of coffee production Resurgence of specialized shade coffee cultivation: Effects on pollination services and quality of coffee production
Since the early 2000s, there has been a resurgence in shade coffee production on the island of Puerto Rico. The newly restored specialized shade canopy consists of four native tree species, three of which are nitrogen fixers, and is intended to provide 30% shade cover once the trees are matured. Though much is known about the benefits of rustic and traditional shade plantations to coffee

Optimal treatment allocations in space and time for online control of anemerging infectious disease Optimal treatment allocations in space and time for online control of anemerging infectious disease
A key component in controlling the spread of an epidemic is deciding where, when and to whom to apply an intervention. We develop a framework for using data to inform these decisions in realtime. We formalize a treatment allocation strategy as a sequence of functions, one per treatment period, that map up‐to‐date information on the spread of an infectious disease to a subset of locations...

Avian response to shade‐layer restoration in coffee plantations in Puerto Rico Avian response to shade‐layer restoration in coffee plantations in Puerto Rico
Documenting the evolving processes associated with habitat restoration and how long it takes to detect avian demographic responses is crucial to evaluate the success of restoration initiatives and to identify ways to improve their effectiveness. The importance of this endeavor prompted the U.S. Fish and Wildlife Service and the USDA Natural Resources Conservation Service to evaluate...

Demographic rates of two southeastern populations of Painted Bunting, 2007–2015 Demographic rates of two southeastern populations of Painted Bunting, 2007–2015
Painted Buntings (Passerina ciris) have been declining in the southeastern United States since the 1970s. A recent demographic assessment highlighted the importance of estimating demographic parameters, which have received little attention to date. The dearth of information is troublesome because attempts to reverse declining trends require a better understanding of the relationship...

Occupancy and abundance of Eleutherodactylus wightmanae and E. brittoni along elevational gradients in west-central Puerto Rico Occupancy and abundance of Eleutherodactylus wightmanae and E. brittoni along elevational gradients in west-central Puerto Rico
Populations of Eleutherodactylus species in Puerto Rico have declined in recent decades due to habitat loss and long-term climatic changes. The conservation of these habitat specialists requires an understanding of factors influencing their abundance and distribution, which at present is scant. We estimated occupancy probability and the probability of encountering ≥2 individuals of E...

Sampling bees in tropical forests and agroecosystems: A review Sampling bees in tropical forests and agroecosystems: A review
Bees are the predominant pollinating taxa, providing a critical ecosystem service upon which many angiosperms rely for successful reproduction. Available data suggests that bee populations worldwide are declining, but scarce data in tropical regions precludes assessing their status and distribution, impact on ecological services, and response to management actions. Herein, we reviewed...

Indicator-driven conservation planning across terrestrial, freshwater aquatic, and marine ecosystems of the south Atlantic, USA Indicator-driven conservation planning across terrestrial, freshwater aquatic, and marine ecosystems of the south Atlantic, USA
Systematic conservation planning, a widely used approach to identify priority lands and waters, uses efficient, defensible, and transparent methods aimed at conserving biodiversity and ecological systems. Limited financial resources and competing land uses can be major impediments to conservation; therefore, participation of diverse stakeholders in the planning process is advantageous to...

Occupancy and abundance of Eleutherodactylus frogs in coffee plantations in Puerto Rico Occupancy and abundance of Eleutherodactylus frogs in coffee plantations in Puerto Rico
Shaded coffee plantations are of conservation value for many taxa, particularly for resident avifauna in the face of extensive landscape changes. Yet, little is known about the value of coffee plantations for amphibians because there are scant demographic data to index their value among species with different habitat preferences. We estimated the probability of occupancy of three frog...

Ecological regime shift drives declining growth rates of sea turtles throughout the West Atlantic Ecological regime shift drives declining growth rates of sea turtles throughout the West Atlantic
Somatic growth is an integrated, individual-based response to environmental conditions, especially in ectotherms. Growth dynamics of large, mobile animals are particularly useful as bio-indicators of environmental change at regional scales. We assembled growth rate data from throughout the West Atlantic for green turtles, Chelonia mydas, which are long-lived, highly migratory, primarily
