“…The Guánica breeding pond is closed for three weeks during the breeding season and is no longer drained for parking (Johnson 1990). Toads have been radiotracked to monitor movements, and habitat characteristics have been evaluated (Johnson 1990;Matos-Torres 2006). Wild individuals were collected during the 1980s to establish two breeding colonies representing the northern (four founders) and southern (32 founders) populations.…”

The Puerto Rican crested toad (Peltophryne lemur) is currently composed of a single wild population on the south coast of Puerto Rico and two captive populations founded by animals from the northern and southern coasts. The main factors contributing to its decline are habitat loss, inundation of breeding ponds during storms, and impacts of invasive species. Recovery efforts have been extensive, involving captive breeding and reintroductions, habitat restoration, construction of breeding ponds, and public education. To guide future conservation efforts, genetic variation and differentiation were assessed for the two captive colonies and the remaining wild population using the mitochondrial control region and six novel microsatellite loci. Only two moderately divergent mitochondrial haplotypes were found, with one fixed in each of the southern and northern lineages. Moderate genetic variation exists for microsatellite loci in all three groups. The captive southern population has not diverged substantially from the wild population at microsatellite loci (F ST = 0.03), whereas there is little allelic overlap between the northern and southern lineages at five of six loci (F ST [ 0.3). Despite this differentiation, they are no more divergent than many populations of other amphibian species. As the northern breeding colony may not remain viable due to its small size and inbred nature, it is recommended that a third breeding colony be established in which northern and southern individuals are combined. This will preserve any northern adaptive traits that may exist, and provide animals for release in the event that the pure northern lineage becomes extirpated.

“…In the north coast, the center of distribution of this species is Quebradillas, while in the south coast it is the Guánica Commonwealth Forest. The breeding site of the southern population is protected by patrolling and kept off limits to the public (Miller 1985, Moreno 1991. The northern population is scattered throughout many locations, mostly private lands (García Díaz 1967, Rivero et al 1980, Rivero and Seguí Crespo 1992, Hernández Prieto 2001, and is not protected.…”
