We report an adult female and subadult specimen of the frog Lithobates magnaocularis Frost & Bagnara, 1974 from tropical deciduous forest habitat in the Municipality of Calvillo, Aguascalientes and Valparaiso, Zacatecas, Mexico. These vouchers represent the first state records of L. magnaocularis for Aguascalientes and Zacatecas, and extend the known distribution of the species through the northeastern portion of the tributaries of the Río Grande de Santiago basin.

Abundance And Diversity

The abundance and diversity of soil arthropods in the Marottichal tropical deciduous forest and Kodungallur mangrove habitat of Thrissur District were studied. A total of 98 species belonging to 15 orders and 5 classes were obtained from the study area. Of these, 59 species belonging to 13 orders and 3 classes were recorded from forest habitat and 47 species belonging to 8 orders and 4 classes from mangroves. Order Coleoptera was the most abundant in both forest (30.69%) and mangrove (36.5%) habitats. Sorenson’s similarity index showed only 15.09% similarity among species indicating that both the habitats harboured significantly different types of species. It was noted that, as the humidity and moisture decreased, the abundance of species also decreased in both habitats. Temperature was negatively correlated with abundance of species. The diversity in forest habitat (4.03) was higher than mangrove habitat (3.77). Maximum abundance was recorded during monsoon season (June- August) and least during winter season (December- February). The species accumulation curve plotted for the study area indicated that there are more species likely to be discovered in both the habitats.

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.

Abstract The goal of this study was to identify which bird species consume Solanum granuloso-leprosum fruits and disperse its seeds. 60 hours of focal observations were carried out between April and May 2006 on the edge of a deciduous forest fragment in the Uruguay River region, Rio Grande do Sul state, Brazil. Ten species were observed in total removing 443 fruits. Saltator similis removed 61.8% of the fruits, followed by Tangara sayaca (17.1%), Pipraeidea bonariensis (11.7%), and T. preciosa (6.8%), while the remaining six species accounted for only 2.5% of the fruits removed. Most fruit removal occurred early in the day or mid-afternoon. The most common feeding behaviors were picking (60.7%), followed by stalling (23%) and hovering (16%). Birds flew more than 10 m from the fruit plant in 62% of the removal events. All bird species observed here may be considered potential dispersers of S. granuloso-leprosum, as they moved the seeds away from the mother plant where strong competition and predation are likely to occur. Results also suggest that S. granuloso-leprosum may be useful in ecological restoration programs.

Abstract: We present an Odonata (Insecta) check list of species occurring in a fragment of the Seasonal Deciduous Forest (Atlantic Forest biome) from the central region of the state of Rio Grande do Sul (RS), southern Brazil, along with a list of the odonate species recorded in this phytoecological region for the state. In addition, we provide comments on the seasonal distribution of the species occurring in the study area. Two streams and seven farm ponds located in the middle course of the Jacuí River basin were surveyed between December 2007 and February 2009. Overall, we recorded 49 species from 21 genera and six families. Argia serva Hagen in Selys, 1865 (Coenagrionidade) had its first occurrence record mentioned for the state, elevating to 183 the total number of Odonata species occurring in Rio Grande do Sul. The number of species recorded in the study area corresponds to ~26% of the known Odonata diversity in RS. Libellulidae was the most species-rich family (22 species, ~45% of the total), followed by Coenagrionidae (18 species, 37% of the total). The checklist for the Seasonal Deciduous Forest in RS indicated the occurrence of 83 species of Odonata in this phytoecological region (~45% of the known odonate species in the state). This elevated diversity could be related to the density of the vegetation structure. In the study area, 20 species were found in streams, and 45 in farm ponds. Species occurrence showed marked seasonal patterns in the study area, with 88% of the species recorded from summer to autumn, and no species detected in streams in the winter. Moreover, 70% of the species were recorded in either one or two seasons in farm ponds, while 65% occurred solely in one season in streams. This result indicates that the life cycle of Odonata in southern Brazil is strongly influenced by seasonal patterns in temperature.

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.
