Disperser Effectiveness

Effectiveness of seed dispersal by different species that feed on the fruits of Myrtillocactus geometrizans was evaluated, considering both quantity and quality of dispersal, in a patch of tropical deciduous forest in Zapotitlán de las Salinas. Effectiveness was estimated to be strongly influenced by the post-foraging movements of the frugivores, leading us to suggest that the quality component of seed dispersal occupies a central role in the assessment of disperser effectiveness and to expect that dispersers that stay in the tropical deciduous forest patch after foraging would have highest effectiveness. Birds were the principal dispersers of M. geometrizans. This was particularly true of Phainopepla nitens, since this species showed a high fidelity within the tropical deciduous forest. These observations emphasize that it is important to determine the post-foraging habits of seed dispersers that may move across vegetation patches over the landscape in order to obtain a complete assessment of their role in Neotropical environments.

<p><strong>Background:</strong> The Sayula sub-basin presents a complex landscape composed of plants communities that to date have not been studied in a timely manner, so this study contributes to the knowledge of the flora and vegetation of the area and the State.</p><p><strong>Question:</strong> i) How many and which families, genera and species are in the Sayula sub-basin? ii) What are the main biological forms of the species? iii) Are there species under any category of protection? iv) How many vegetation types are present within the region?<br /> <strong>Studied species:</strong> Ferns, Gymnosperms and Angiosperms.<br /> <strong>Study site and years of study:</strong> The Sayula sub-basin, Jalisco, Mexico; from February 2012 to October 2015.<br /> <strong>Methods:</strong> Through the literature review and field work the floristic checklist was elaborated. In addition, with the use of geographic information systems, a map of land use and vegetation was made.<br /> <strong>Results:</strong> A total of 687 species were recorded, including 415 genera and 113 families. The five main families were Poaceae, Asteraceae, Fabaceae Solanaceae and Euphorbiaceae representing 42.6 % of the total species and 36.6 % of the genera. It should be noted that the predominant biological forms were herbs with 409, 105 shrubs and 74 trees. On the other hand, 47 species registered under some protection category of which, only one species <em>Cleomella jaliscensis</em> is endemic to the region. Finally, eight vegetation types were determined, being the tropical deciduous forest the one that occupies greater surface and presents greater floristic diversity.<br /> <strong>Conclusions:</strong> It is important to emphasize that during the realization of the work, agricultural activities were detected affecting the flora and vegetation, threatening the biodiversity and the natural balance of the region.</p>

An annotated list of vascular plant species and a floristic description of the vegetation types of the Huatulco National Park, Oaxaca, Mexico, are presented. Floristic exploration upon which the list is based took place in an area of approximately 6,374.98 ha. The study consisted of 18 collecting trips during which 4,382 numbers of vascular plants were collected, at altitudes ranging from sea level to 200 m. Of the 3,312 collections determined so far, 91 families, 391 genera, and 736 species are reported. The dominant families in number of species are Leguminosae (146), Euphorbiaceae (48), Asteraceae (42), and Convolvulaceae (37). Vegetation types recognized are coastal dune vegetation, gallery forest, mangroves, thorn forest, tropical deciduous forest, tropical subdeciduous forest, savanna, and secondary vegetation.

Holocene Record

AbstractA phytolith record from Monte Oscuro, a crater lake located 10 m above sea level on the Pacific coastal plain of Panama, shows that during the Late Pleistocene the lake bed was dry and savanna-like vegetation expanded at the expense of tropical deciduous forest, the modern potential vegetation. A significant reduction of precipitation below current levels was almost certainly required to effect the changes observed. Core sediment characteristics indicate that permanent inundation of the Monte Oscuro basin with water occurred at about 10,500 14C yr B.P. Pollen and phytolith records show that deciduous tropical forest expanded into the lake’s watershed during the early Holocene. Significant burning of the vegetation and increases of weedy plants at ca. 7500 to 7000 14C yr B.P. indicate disturbance, which most likely resulted from early human occupation of the seasonal tropical forest near Monte Oscuro and the development of slash-and-burn methods of cultivation.

Dry Deciduous Forest

The specific gravity of 220 woody species, half of them from a tropical rainforest, half from a tropical deciduous forest was measured. The two groups were compared using a Student t-test. The results show highly significant differences in specific gravity between the species from the two areas: woods from the dry deciduous forest tend to be much heavier than those from the rainforest.

A total of 502 species that belong to 115 families and 301 genera were recorded for Mt. El Cebu and adjacent zones in Polygon V of the El Triunfo Biosphere Reserve. The most speciose families were Orchiclaceae, Fabaceae, Asteraceae, Bromeliaceae and polypodiaceae with 58, 29, 28, 17, and 17 species, respectively. Six plant communities were recognized in the area, among which the cloud forest was the most diverse with 234 species, followed by pine-oak fore st with 150 species, and the tropical rain forest with 127. The oak forest and the tropical deciduous forest were less diverse, with 71 and 39 species, respectively. Only 13 species are included in the Mexican red list of endangered taxa.

Female Flowers

A hierarchy of phenological features defines the opportunities for breeding in a population of Cnidoscolus spinosus in a tropical deciduous forest in western Mexico. On any one tree, inflorescences develop in rough synchrony and all present flowers of both sexes. Only female flowers develop at the lowest ranks of ramification but only males develop later. Overlap of the mature period of flowers of both sexes is uncommon on one inflorescence of between inflorescences : individual trees are functionally female or male at any moment. lnter-tree synchrony may thus reduce successful breeding. Asynchrony is achieved in part by differences in the onset of flowering, but also by variance in the lenght of individual flowering cycles. The occurrence of two or three cycles per tree during one season for the population increases its breeding opportunities.
