Catálogo de la flora (Angiospermas) del páramo de Bijagual, Boyacá, Colombia

Abstract

Se elaboró un catálogo de las angiospermas del páramo de Bijagual con información de las especies, distribución local y nacional. Se registraron 35 familias, 73 géneros y 120 especies.

Spatial and Temporal Dynamics of the Vegetation Cover from the Bijagual Massif, Boyacá, Colombia, during the 1986–2021 Period

“…Cuatrec., E. murilloi Cuatrec., and Puya goudotiana Mez. [37] were found in the paramo ecosystem. In addition, species widely distributed in the high Andean forests and paramos in Boyacá were recorded, including angelitos (Monochaetum myrtoideum Naudin, M. uribei Wurdack, and M. meridense Naudin), chites (Hypericum laricifolium Juss., H. mexicanum L., H. myricariifolium Hieron., and H. lycopodioides Triana & Planch.…”

“…The pajonal-chuscal formations are comprised of Agrostis perennans (Walter) Tuck., Anthoxanthum odoratum L., Calamagrostis effusa (Kunth) Steud., and Chusquea tessellata Munro., among others. Frailejonal formations include Espeletia argentea Bonpl., E. boyacensis Cuatrec., and E. murilloi Cuatrec., and the sphagnals formation comprises a complex of Sphagnum species [34,37].…”

“…The Bijagual Massif corresponds to one of the six high mountain natural areas in Boyacá with broad floristic diversity [27,38]. The field verification process and the consultation of herbarium biological collections [35,37] allowed estimating a richness of up to 327 species for the Hof cover and up to 120 species for Dgnm. The results of the spatiotemporal dynamics showed that this diversity is vulnerable to the effects of the pasture and crop matrix since it has caused modifications in the vegetation [40].…”

“…Griseb., and Holcus lanatus L. in paramos indicate that the composition and physiognomy of these covers have been modified, enhancing the loss of richness and forming more heterogeneous plant communities. Even so, the research carried out by Gil-Leguizamón et al [34,35] and Carrillo et al [37] relate some species of ecological importance, including trees, shrubs, rosettes, and grasses that characterize the physiognomy of the Andean forest, such as C. multiflora, C. elliptica, C. alata, W. rollottii, B. comocladifolia, V. triphyllum, and E. myrtilloides, and then the species In 1986 and 2000, the Hof and Dgnm covers showed patches with habitat quality and availability for biota (connectivity within the patch) and act as dispersal flows (connectivity between patches); however, these ecological characteristics decreased drastically in 2021 for the two covers. Both Hof and Dgnm patches provide different connectivity values, evidenced in the dispersion of the standard deviation data concerning the average of each fraction by cover type and time (Figure 5A).…”

M. Tryon & Stolze, Calamagrostis effusa (Kunth) Steud., and Rhynchospora ruiziana Boeckeler typical of paramos. These records agree with the altitudinal delimitation of the vegetation proposed by Cuatrecasas [41].…”
