Spatial distribution of bat species on Hispaniola island, the Greater Antilles
(2022)Hispaniola shows the highest environmental heterogeneity among the Greater Antilles mainly due to its complex land relief, encompassing a high ecosystemic heterogeineity, and bats as one o the most representative group of ... -
Spatial distribution of humpback whales (Megaptera novaeangliae) in Samaná Bay, Dominican Republic
(2012)Observations of humpback whales (location, number and social groupings) were collected on board commercial whale watch vessels in January, February and March, 1999 to 2011, at the eastern end of Samaná Bay and the surrounding ... -

(2015)Cyclura ricordii is an endemic iguana from Hispaniola and is listed as Critically Endangered on the IUCN. The main threats are predation by introduced mammals, habitat destruction and hunting. The present study focused on ... -
Spatial patterns of biomass and aboveground net primary productivity in a mangrove ecosystem in the Dominican Republic
(2003)The objective of this study was to quantify spatial patterns in above and below ground biomass, primary productivity, and growth efficiency along a tidal gradient in a 4700-ha mangrove forest in the Dominican Republic. We ... -
Spatial segregation between phenotypes of the diablotin Black-capped Petrel Pterodroma hasitata during the non-breeding period
(2023)Despite growing support for ecosystem-based approaches, conservation is mostly implemented at the species level. However, genetic differentiation exists within this taxonomic level, putting genetically distinct populations ... -
Speciation, heterochrony, and genetic variation in Hispaniolan Palm-Tanagers
(1990)We documented levels of genetic variability for two species of Hispaniolan palm-tanagers. Significant differences between age classes in levels of genetic heterozygosity were concordant with an age dimorphism in foraging ... -
Species assemblages of insular Caribbean Sticta (lichenized Ascomycota: Peltigerales) over ecological and evolutionary time scales
(2023)Phylogenetic approaches to macroevolution have provided unique insight into evolutionary relationships, ancestral ranges, and diversification patterns for many taxa. Similar frameworks have also been developed to assess ... -
Species diversity, habitat distribution, and blood meal analysis of Haematophagous Dipterans collected by CDC-UV light traps in the Dominican Republic
(2022)Haematophagous insects cause major economic losses by both direct damage and the transmission of pathogens. However, the biting Diptera species in the Caribbean region have been poorly documented. During 2021, CDC downdraft ... -
Stable isotopes reveal seasonal dietary responses to agroforestry in a venomous mammal, the Hispaniolan solenodon (Solenodon paradoxus)
(2022)While trends in tropical deforestation are alarming, conservation biologists are increasingly recognizing the potential for species survival in human-modified landscapes. Identifying the factors underlying such persistence, ... -
Status and trends of Caribbean coral reefs : 1970-2012
(2014)This work is the most comprehensive analysis and compilation of information on coral reef in the Caribbean over the past 40 years. Although the report clearly shows that there has been an ongoing decline in coral cover and ... -

Status of Caribbean coral reefs after bleaching and hurricanes in 2005
(2008)The most extreme coral bleaching and mortality event to hit the Wider Caribbean (including Atlantic) coral reefs occurred in 2005. This was during the warmest year ever recorded, eclipsing the 9 warmest years that had ... -
Status of Caribbean forest endemics special issue : editors' foreword
(2017)The high degree of avian endemism in the Caribbean is arguably one of the most defining qualities of the region, and an irreplaceable part of its natural heritage. However, these Small Island Developing States (SIDS) face ... -
