Street-level green spaces support a key urban population of the threatened Hispaniolan parakeet Psittacara chloropterus
(2021)While urbanisation remains a major threat to biodiversity, urban areas can sometimes play an important role in protecting threatened species, especially exploited taxa such as parrots. The Hispaniolan Parakeet Psittacara ... -
Sweet drinks are made of this : conservation genetics of an endemic palm species from the Dominican Republic
(2011)Pseudophoenix ekmanii is a threatened palm species endemic to the Dominican Republic. Sap from trees is extracted to make a local drink; once they are tapped the individual usually dies. Plants are also illegally harvested ... -
Tendencias en la biodiversidad de los arrecifes de coral de República Dominicana
(2023)En 2015, iniciamos un programa de monitoreo de ecosistemas de arrecifes de coral a nivel nacional en la República Dominicana (RD) para establecer referentes de biodiversidad contra los cuales se podrían rastrear las ... -
The evolutionary history of the Caribbean magnolias (Magnoliaceae) : testing species delimitations and biogeographical hypotheses using molecular data
(2022)The Caribbean islands provide an ideal setting for studying biodiversity, given their complex geological and environmental history, and their historical and current geographical proximity to the American mainland. Magnolia, ... -
The Golden Swallow Project (Proyecto Golondrina Verde) : Hispaniolan & Jamaican Golden Swallows
(2013)Aerial insectivore species in the Greater Antilles of the Caribbean are almost completely absent from the scientific literature. The paucity of work being conducted on this guild makes broad-scale and comparative population ... -
The multidimensional (and contrasting) effects of environmental warming on a group of montane tropical lizards
(2022)Mountains are cradles for biodiversity and crucibles for climate-driven species loss, particularly for tropical ectotherms. Constriction on activity and amplified heat stress are two key sources of warming-driven vulnerability ... -
The value of endangered species in protected areas at risk : the case of the leatherback turtle in the Dominican Republic
(2014)Protected areas are considered essential elements for global biodiversity conservation. They may not necessarily result in an effective conservation of resources in developing countries due to lack of funding for management ... -
Trends in Dominican Republic coral reef biodiversity 2015–2022
(2023)In 2015, we initiated a country-wide coral reef ecosystem-monitoring program in the Dominican Republic (DR) to establish biodiversity baselines against which trends in the most important components of coral reef ecosystem’s ... -
Uncertain future for global sea turtle populations in face of sea level rise
(2023)Sea level rise has accelerated during recent decades, exceeding rates recorded during the previous two millennia, and as a result many coastal habitats and species around the globe are being impacted. This situation is ... -
Uncovering life history traits and conservation strategies for the Golden Swallow, Tachycineta euchrysea sclateri, a threatened and endemic passerine on the island of Hispaniola : 2013 field season report
(2013)The Golden Swallow Project saw its second successful year in the Dominican Republic in 2013. Returning with a better understanding of the Golden swallows allowed us to refine our methodologies and interact at a much more ... -
Uncovering life history traits and conservation strategies for the Golden Swallow, Tachycineta euchrysea sclateri, a threatened and endemic passerine on the island of Hispaniola : 2014 field season report
(2014)The 2014 field season saw the continued collection of annual data on the breeding life history of the Golden Swallows via artificial nest-box monitoring. Moreso than years prior, however, we spent considerable time focusing ... -
Uncovering life history traits and conservation strategies for the Golden Swallow, Tachycineta euchrysea, a threatened and endemic passerine on the island of Hispaniola : 2012 field season report
(2012)In 2008, nest boxes were erected in the Cordillera Central of the Dominican Republic in an effort to attract a returning population of breeding Golden Swallows, an endemic and threatened passerine declining in numbers for ... -
West Indian manatees (Trichechus manatus) in the wider Caribbean region
(2012)In this chapter we address conservation of the remaining West Indian manatees in the Wider Caribbean (WCR), including those populations within the Caribbean Sea, the western Gulf of Mexico and along the Atlantic coasts of ... -
Widespread loss of Caribbean acroporid corals was underway before coral bleaching and disease outbreaks
(2020)The mass mortality of acroporid corals has transformed Caribbean reefs from coral- to macroalgal-dominated habitats since systematic monitoring began in the 1970s. Declines have been attributed to overfishing, pollution, ...
