Fenología floral de una comunidad árido-tropical de Baja California Sur, México

| description | A flowering phenology study was carried out in a plant community close to the Gulf of California coast in the southern part of Baja California Sur, Mexico. The area is located on the border between two phytographical provinces: the Cape Region of arid-tropical features and the Sonoran Desert. Among several characteristics, the site presents a bimodal rain pattern, the maxima corresponding to the late summer and winter seasons. For two years the presence-absence of flowers of 136 species of vascular plants were registered in an area of 200 hectares. Species were grouped according to their life forms in: 13 trees; 46 shrubs, 52 herbs (37 annuals, and 15 perennials), 11 succulents, 11 climbing vines and 3 parasites. The same taxa were grouped according to their flowering response in three classes: a) flowering induced by the rainy season (60); b) flowering in the dry season (46); and c) species of irregular or maintained flowering pattern (30). The flowering spectrum obtained from two years of observation shows that the woody species, as a group, exhibit flowers all the year. Flower synchrony at the study site seems to be less pronounced than that reported from a subtropical plant community on the near coast of mainland Mexico. |

Se efectuó un estudio fenológico floral en una comunidad vegetal cercana a la costa del Mar de Cortés, en el sur de Baja California Sur, México. El sitio se ubica en los límites de dos provincias fitogeográficas: la Región del Cabo, de características árido-tropicales y el Desierto Sonorense. Entre otras particularidades, en la localidad se presenta un patrón de lluvias bimodal, con máximas correspondientes a los períodos de verano y de invierno. En 200 ha de superficie se registró por dos años la presencia y ausencia de floración en 136 especies de plantas vasculares, agrupadas de acuerdo con su forma de crecimiento en: 13 árboles, 46 arbustos, 52 herbáceas (37 anuales y 15 perennes), 11 suculentas, 11 trepadoras, y 3 parásitas. Los mismos taxa se ubicaron, atendiendo a su respuesta de floración en tres clases: a) inducida por la precipitación pluvial (60); b) fuera de la temporada de lluvias (46); y c) con patrón irregular o sostenido (30). El espectro de floración en los dos ciclos de observación muestra que las especies leñosas, como grupo, se mantuvieron en flor durante todo este período. La sincronía en la floración de las especies en el sitio de estudio parece ser inferior a la registrada en una comunidad subtropical en la costa mexicana contigua.
