Doubtful Species

Myrtaceae is one of the largest families in number of species within the order Myrtales and one of the richest families in Brazil. Myrcia is the fourth largest genus of Myrtaceae, with approximately 770 species distributed from Central America and the Caribbean to southern South America. In Brazil Myrcia is represented by 397 species, of which 309 are endemic. In this study, we present the taxonomic treatment for all species of Myrcia that occur in Paraná state, Brazil. Analyses of herbarium specimens, online databases, and bibliography were performed. Fifty-three species of Myrcia occur in Paraná, distributed in all vegetation types. Twenty-three names were excluded from previous lists of species or listed as doubtful species. Neither of the recorded species is endemic to Paraná, but this state is the southern and northern limit of distribution of six and two species, respectively. We present an identification key, taxonomic descriptions, figures, maps, and comments on phenology, habitat, and morphology for each species.

Migratory Stopover

Abstract The Newfoundland subspecies of Gray-cheeked Thrush (Catharus minimus minimus) has declined since the 1980s and degradation of winter habitat has been suggested as a contributing stressor. However, the winter range of this subspecies is not well understood, so we fitted 29 males with archival GPS tags during summer 2016. Four tagged thrushes were recaptured in summer 2017 and, though all tags had missing locations and broken antennae, the data retrieved showed that one thrush wintered in the Sierra Nevada de Santa Marta (SNSM) in northern Colombia, one in the nearby Sierra de Perija in Venezuela, and a third may have settled in the same region. One tag provided locations until April 21 and that thrush was consistently detected within a ~1 ha area through the winter. Locations obtained during fall migration indicated that thrushes travelled to South America via Central America and possibly by directly crossing the Caribbean. Contemporary research indicates that the SNSM is an important migratory stopover for Northern Gray-cheeked Thrushes (C. m. aliciae) but a historical report coupled with our observations suggest winter use of the SNSM and adjacent areas in northern South America by C. m. minimus, though numbers may be lower than during the 1900s.

This review highlights the history of Developmental Biology studies in Latin-American countries of Central America, the northern region of South America and the Caribbean and their impact on the field. For this, we have compiled the contributions made by investigators in various institutions of the region, including universities, agricultural, research and health centers. Most of the contributions focus on particular fields, among them, Evo-Devo, regenerative biology, nervous system development and health related issues. A large share of the contributions originates from a subset of countries, primarily, Colombia, Costa Rica, Ecuador, Panama and Puerto Rico. In addition, we underscore the new investigators and the ongoing research in the region.

Abstract D. eriantha is a perennial grass not considered as a serious weed in some countries, but a competitive and aggressive weed in others (PROTA, 2016; Tropical Forages, 2016; Weeds of Australia, 2016). The species is listed as invasive in Central America (Costa Rica), the Caribbean (Cuba), South America (Colombia, Ecuador) and Oceania (Australia, USA-Hawaii) (Oviedo Prieto et al., 2012; PIER, 2016). Catasús Guerra (2015), however, argues that the species should not be on the list of the invasive species for Cuba, due to lack of spread as it is being over-grazed and not producing viable seeds. It is on the list of the top 200 most invasive species in Queensland, Australia, forming dense populations in riparian areas, open woodlands and on some beaches (Weeds of Australia, 2016).
