    “…However, from both morphological and phylogenetic perspectives, the Chinese specimens labelled as N. melanoporus are found not to be conspecific with the specimens of N. melanoporus from Costa Rica, close to the type locality in Cuba. These Chinese specimens are thus described as a new species Nigrofomes sinomelanoporus. …”

    “…In the phylogenetic reconstruction inferred, the new species clustered in two different clades related to species from USA, Costa Rica and Panama. The recollection of fructifications in monodominant stands of either Quercusoleoides or Q.sapotifolia, allowed recognizing the distribution of one of the Phylloporus species under both Quercus species, and the other under Q.oleoides only. …”

    “…We test this hypothesis by studying populations of the fish species Poeciliopsis retropinna in Costa Rica. We found substantial variation in the degree of placentation among natural populations associated with predation risk: females from high predation populations had significantly higher degrees of placentation compared to low predation females, while number, size and quality of offspring at birth remained unaffected. …”
