Submitted by Greetchen Díaz-Muñoz on

Aunque su obra fue subestimada, Ana Roqué de Duprey legó uno de los textos más relevantes en la historia de la ciencia de principios del siglo XX en las Américas. Hoy, 90 años después de escribir la ‘Botánica antillana’, una investigación revela el valor del libro inédito.

Así comienza la crónica que el periodista, Eliván Martínez Mercado escribió como producto de su trabajo para el Centro de Periodismo Investigativo. Quedé fascinada desde la primera vez que Eliván compartió esta historia conmigo y cuando ustedes lean esta excelente pieza periodística, seguro sabrán el porqué.

Archaeological starch grains consistent with those produced and stored in modern cojoba (Anadenanthera peregrina) seeds were identified, for the first time in the West Indies, in a coral milling base recovered in a small precolonial habitation site of Eastern Puerto Rico, in a context dated to A.D. 115–1250. Ethnohistoric, ethnographic, and previous archaeological data on cojoba from the West Indies and South America were surveyed in order to form plausible sociocultural interpretations of the findings.

The scaly-naped pigeon (Patagioenas squamosa) is threatened by hunting in the Caribbean. At present, the pigeon is abundant in Puerto Rico, but overharvesting is a major concern; therefore, the development of a sustainable harvest strategy is a management priority. The management objective of the harvest strategy is to maximize hunting opportunity while keeping the population above an abundance threshold (NT) of 260,000 pigeons.

La evidencia del pasado puede ser guardada en formato digital o en formato análogo; mediante fotografía o árboles genealógicos. Sin embargo, estas herramientas suelen ser poco útiles si queremos explorar nuestra historia hace siglos o milenios atrás.
