Affinities of the Ocotea (Lauraceae) species from Cuba

Feddes Repertorium, Volume 135, Issue 4, Page 331-345, December 2024.
Abstract The affinities of the Ocotea species from Cuba are examined based on sequences of the nuclear ITS region and the chloroplast psbA‐trnH spacer, supplemented by SEM studies on stomatal morphology. The species with bisexual flowers, all of them endemic either to the Greater Antilles or Cuba only, form (at least) two phylogenetically distinct ...

Conservation status of three rare endemic Phaseolus bean (Leguminosae, Phaseoleae) species of Costa Rica

Nordic Journal of Botany, Volume 2024, Issue 12, December 2024.
We aimed at an inventory of all populations of wild Phaseolus (bean) species in Costa Rica, in relation to future plant breeding. During the field work in 2003–2018, three new and rare bean species (i.e. P. albicarminus, P. angucianae and P. hygrophilus) were found in different montane forest habitats which originally occupy a small acreage.

Field experience with the 8‐HPV‐type oncoprotein test for cervical cancer screening among HPV‐positive women living with and without HIV in LMICs

International Journal of Cancer, Volume 155, Issue 5, Page 816-827, 1 September 2024.
What's new? There is a need for biomarker tests that distinguish between transient and persistent HPV infection and can be performed in a limited‐resource setting. Here, the authors assessed the 8‐HPV‐type OncoE6/E7 Cervical Test using samples from HPV‐positive women with and without HIV infection.

A New Lepanthes (Orchidaceae: Pleurothallidinae) from Península de Osa, Puntarenas, Costa Rica

Harvard Papers in Botany, 2020
Lepanthes is one of the most species-rich genera of orchids in the Neotropics, with most of the species found in medium to high elevation forests and few species in lowlands. We describe and illustrate Lepanthes osaensis, a new species from the very wet lowland forest of Peninsula de Osa, Costa Rica.

Complex patch geometries maximize species richness at the expense of forest specialists

Biotropica, Volume 56, Issue 3, May 2024.
We assessed the reptile and amphibian community at 54 sites spanning four habitat types in a fragmented landscape in Costa Rica. Our study revealed that small forest patches and corridors play an important role in herpetofauna conservation, as they support a similar richness, abundance, and community composition to large forest preserves. We also found
