Edge Influence

Edge effects are considered a key factor in regulating the structure of plant communities in different ecosystems. However, regardless to few studies, edge influence does not seem to be decisive in semiarid regions such as the Brazilian tropical dry forest known as Caatinga but this issue remains inconclusive. The present study tests the null hypothesis that the plant community of shrubs and trees does not change in its structure due to edge effects. Twenty-four plots (20 x 20 m) were set up in a fragment of Caatinga, in which 12 plots were in the forest edges and 12 plots were inside the fragment. Tree richness, abundance and species composition did not differ between edge and interior plots. The results of this study are in agreement with the pattern previously found for semiarid environments and contrasts with previous results obtained in different environments such as Rainforests, Savanna and Forest of Araucaria, which indicate abrupt differences between the border and interior of the plant communities in these ecosystems, and suggest that the community of woody plants of the Caatinga is not ecologically affected by the presence of edges.

Regeneration Processes

The paper presents the results of field studies of tendencies in plant communities self-regeneration processes in the zone of their technogenic disturbance and on the surfaces of rock spoil heaps. It has been established that in the former case the key factor determining the nature of development of self-regeneration processes is the correspondence of the width of the transitional community to the length of transfer of seeds of primary plant community edificatory and assectator species. In the latter case, the key self-regeneration succession sere passes the bifurcation point at a very early stage of its development.

<p>Se analizó la variación espacio-temporal de la abundancia de las mariposas de la subfamilia Biblidinae (Lepidoptera: Nymphalidae) en un fragmento de Bs-T en la Reserva Campesina La Montaña (RCM), Atlántico, Colombia; desde enero hasta agosto de 2011. Se marcaron cuatro puntos dentro del área de estudio, donde se ubicaron trampas Van Someren–Rydon cebadas con calamar en descomposición, fruta fermentada y con una mezcla de los anteriores cebos. Adicionalmente, se realizó una caracterización de la vegetación por punto, para lo cual se tomaron datos de diámetro a la altura del pecho (DAP), altura y tamaño de la copa para todas aquellas plantas leñosas con DAP mayor o igual a 2,5 cm. Se capturaron 76 individuos agrupados en seis especies y cuatro géneros; destacándose <em>Hamadryas februa</em> (Hübner) como la más dominante con 32 individuos. El mes de marzo presentó la mayor riqueza y abundancia (6 especies y 25 individuos) durantes las primeras lluvias en la zona. El punto 3 presentó los valores más altos de diversidad y abundancia de Biblidinae (5 especies y 37 individuos) y la mayor densidad de árboles (D= 0,28 individuos/m<sup>2</sup>). Se demuestra que la estructura de este grupo de mariposas presenta un patrón temporal y espacial en esta reserva. El análisis de componentes principales demostró que el área basal total (ABT) y la Densidad (D) de plantas leñosas, pueden considerarse como un factor determinante en la distribución y abundancia de las especies de la subfamilia Biblidinae en la RCM.</p><p align="center"><strong>Plant Composition, Feeding Preferences and Abundance of Biblidinae (Lepidoptera: Nymphalidae) in a Tropical Dry Forest Fragment in the Department of Atlántico, Colombia</strong></p><p>The abundance and spatio-temporal variation of butterflies of the Biblidinae subfamily (Lepidoptera: Nymphalidae) in a fragment of Tropical dry forest at the Reserva Campesina La Montaña (RCM), Atlántico, Colombia; from January until August 2011, was analyzed. Within the study area four points were marked; Van Someren-Rydon traps were placed.in each point using rotten squid, fermented fruit and a mixture of both as bait. In addition, a characterization of the vegetation by point was performed, taking data of the diameter to the breast height (DBH), height and size of treetop of all woody plants with a DBH greater than or equal to 2.5 cm. In total 76 butterfly individuals grouped in six species and four genera were captured; being <em>Hamadryas februa</em> (Hübner) the most dominant with 32 individuals. The greatest richness and abundance was recorded in March (6 species and 25 individuals), during the first rains in the study area. The point 3 presented the highest values of diversity and abundance (five species and 37 individuals) of Biblidinae and the higher density of trees (D= 0,28 individuals/m2). The structure of this butterflies group presents a spatio-temporal pattern in this reserve. The principal components analysis showed that the total basal area (ABT) and the density (D) of woody plants, can be considered a determining factor in the distribution and abundance of species of the subfamily Biblidinae at the RCM.</p>

Vegetation Gradient

Conversion to permanent agriculture is rapidly occurring over vast areas of the 1.8 million km2; Brazilian Cerrado; a region that is naturally a mosaic of grasslands, savannas and evergreen tropical woodlands. Yet, few studies have quantified total biomass of plant communities in this ecosystem, particularly the belowground component; a C pool of potential global significance. Total biomass (aboveground and belowground), and the quantity of biomass consumed by fires were measured in four plant communities comprising a vegetation gradient from pure grassland (campo limpo) to a woodland with a closed canopy of tall shrubs and scattered trees (cerrado denso) near Brasilia, DF, Brazil. Total aboveground biomass (TAGB) increased along this gradient from 5.5 Mg ha-1 in campo limpo to 29.4 Mg ha-1 in cerrado denso. Vegetation structure varied among communities; trees were nonexistent in campo limpo, but were at a density of 1000 ha-1 and a biomass of 12.9 Mg ha-1 in cerrado denso. Fires consumed 92 and 84% of the TAGB in campo limpo (pure grassland) and campo sujo (savanna), respectively. In cerrado aberto and cerrado denso, trees and tall shrubs were little affected by fire. Combustion factors of the TAGB in these communities was 54 and 33%, respectively. The total biomass consumed by fire ranged from 5.0 Mg ha-1 in campo limpo to 13.5 Mg ha-1 in cerrado aberto. Compared to other widespread Brazilian ecosystems (tropical dry forest and evergreen forest), the Cerrado has a lower aboveground biomass. The TAGB of cerrado denso is > 9% of that of Amazonian tropical evergreen forest. The total quantity of biomass consumed by fire, and hence emissions to the atmosphere is lower in intact Cerrado communities compared to fires in slashed tropical forest.

Biogeographic Provinces

In Central Mexico converge three biogeographic provinces: Altiplano sur, Sierra Madre Occidental and Costa del Pacífico. Each one of them is composed by different plant communities: Thorn Forest, Temperate Mountain Forest and Dry Tropical Forest respectively. Our objective is to show, through phytoecological analysis, the species richness, diversity and the structure of the plant communities from the Temperate Mountain Forest and from the Tropical Dry Forest. In the Temperate Mountain Forest, 50 forest species were recorded, with a Shannon Wiener diversity index H´ = 1.63 on altitudes from 2400 to 2600 m. The Whittaker β index is Bw = 7.22. In the tropical dry forest, we identified 79 plants species with a mean diversity index H´ = 3.49 on altitudes from 1951 to 2100 m. In this ecosystem the Bw index is 8.12. This study offers important information for the establishment of management practices, considering the protection status from the areas in which this vegetation type is distributed.
