Germination, carbohydrate composition and vigor of cryopreserved Caesalpinia echinata seeds
(Brazilian Archives of Biology and Technology, 2012)
The present study investigated the germination and vigor of Caesalpinia echinata (Brazilwood) seeds stored at negative temperatures. Recently harvested seeds were cryopreserved at -18º or -196ºC and periodically evaluated ...
Enhancement of palatable perennial grasses by disturbance and seed addition in degraded native grasslands of the dry pampas in Central Argentina
(Taylor & Francis, 2020-05-07)
Land use has changed the original composition of the natural grasslands in the dry pampas of central Argentina, in detriment of palatable perennial grasses (PPG). Long-term elimination of anthropogenic disturbances has not ...
Diet switching of seed-eating birds wintering in grazed habitats of the central Monte Desert, ArgentinaModificación de la dieta invernal de las aves granívoras en hábitats sujetos a pastoreo de la porción central del Desierto del Monte, Argentina
(Cooper Ornithological Society, 2017-08)
Although bird population declines associated with land degradation are common, the initial response of organisms to rapid human-induced environmental change is usually behavioral. Reductions in seed availability due to ...
Physicochemical characterization of Jicaro seeds (Crescentia alata H.B.K.): a novel protein-rich and oleaginous seed
(2017-03)
Jicaro (Crescentia alata) is a tropical tree native to Mesoamerica well adapted to severe drought
conditions. The seeds of the fruits were analyzed for protein, fatty acid, dietary
fiber, phytate, polyphenol,
tannin, ...

Influence of seed size on feeding preferences and diet composition of three sympatric harvester ants in the central Monte Desert, Argentina
(Springer Tokyo, 2010-03)
Selective seed consumption by harvester ants may affect seed abundance and composition and, ultimately, plant communities. We evaluated the influence of seed size on preferences and diet of Pogonomyrmex mendozanus, P. ...
Storage-associated genes and reserves accumulation in soybean cultivars differing in physiological strategies for attaining high seed protein concentration
(Crop Science Society of America, 2017-01)
High seed protein concentration (HP) in soybeans [Glycine max (L.) Merr.] is attained by increases in protein content in large seed genotypes (HP large seed) or by reductions in oil and carbohydrates contents in small seed ...
