Breeding ecology and predictors of nest success in the Critically Endangered Ridgway’s Hawk Buteo ridgwayi
(2015)
Ridgway’s Hawk Buteo ridgwayi is a Critically Endangered forest raptor endemic to the island of Hispaniola in the Caribbean. The species is currently limited to a small area on the north-east coast of the island, with fewer ...
Nestling sex ratio in a critically endangered dimorphic raptor, Ridgway's Hawk (Buteo ridgwayi)
(2013)
[English] Variation in nestling sex ratio is an important concept in population ecology, and has particular implications for the conservation status of small populations. Research on species exhibiting Reversed Sexual Size ...
Social and genetic mating system of Ridgway's hawk (Buteo ridgwayi), an endemic raptor on Hispaniola
(2013)
Patterns of social organization and mating systems have been shown to be functions of ecological factors such as resource allocation and breeding density. In some species, particularly birds, social organization and genetic ...
New population of critically endangered raptor discovered in Haiti
(2021)
Since the last recorded sighting in 1962, Ridgway’s Hawk was unknown from Haiti and was presumed extirpated. But, in August 2019, colleagues from the Haitian conservation organization, JACSEH (Jeunes en Action Pour la ...
Solenodon genome reveals convergent evolution of venom in eulipotyphlan mammals
(2019)
Venom systems are key adaptations that have evolved throughout the tree of life and typically facilitate predation or defense. Despite venoms being model systems for studying a variety of evolutionary and physiological ...
Conservation strategies for West Indian rock iguanas (genus Cyclura) : current efforts and future directions
(2004)
As a result of habitat loss and the negative impact of introduced mammalian predators and competitors, West Indian Rock Iguanas (genus Cyclura) are among the most endangered lizards in the world. Because they are important ...
Pre-breeding behavior of Ridgway’s Hawks (Buteo ridgwayi) in Punta Cana, Dominican Republic
(2023)
Abstract: Recent conservation work by The Peregrine Fund has established a translocated population of the Critically Endangered Ridgway’s Hawk (Buteo ridgwayi) in Punta Cana, Dominican Republic. Although Ridgway’s Hawk has ...
Independent evolutionary histories in allopatric populations of a threatened Caribbean land mammal
(2016)
Aim: To determine the evolutionary history, relationships and distinctiveness of allopatric populations of Hispaniolan solenodon (Solenodon paradoxus), a highly threatened Caribbean ‘relict’ mammal, to understand spatio-temporal ...
Population history of the Hispaniolan hutia Plagiodontia aedium (Rodentia: Capromyidae) : testing the model of ancient differentiation on a geotectonically complex Caribbean island
(2012)
Hispaniola is a geotectonically complex island consisting of two palaeo-islands that docked c. 10 Ma, with a further geological boundary subdividing the southern palaeo-island into eastern and western regions. All three ...
A new subspecies of hutia (Plagiodontia, Capromyidae, Rodentia) from southern Hispaniola
(2015)
Continued uncertainty persists over the taxonomic status of many threatened Caribbean mammal populations. Recent molecular analysis has identified three genetically isolated allopatric hutia populations on Hispaniola that ...
