Deciduous Dry Forest

Diversity and similarity of butterfly communities were assessed in three different habitat types in the mountains of Nahan, Himachal Pradesh, from May 2012 to April 2013. A total of 75 species and five families were reported. Proportion of species was highest in deciduous dry forest (49%), followed by Shorea (Saal) forest (34%), and Pinus (Cheer) forest (17%). Family Pieridae was dominant followed by Nymphalidae in all three habitat types. Cluster analysis revealed that Cheer forest  stood out clearly from Dry and Saal forest which represents the different species composition. We found significant differences in butterfly diversity in the three forest types based on Shannon index, Simpson dominance index, and Buzas & Gibson’s evenness. These differences may be attributable to variations in host and nectar plant distribution. Of the habitats surveyed, dry deciduous forest appeared to be the most suitable for butterfly conservation.

Dry Deciduous Forest

Reptiles are key animals in vertebrate communities in most ecosystems. However, there is little information on their diversity and abundance in dry forests of Ecuador. Between 2013 and 2014 we studied the reptile diversity and natural history of the Puyango Protected Forest, on the border between the province of Loja and El Oro, Ecuador. This area protects relicts of dry deciduous forest in hills and patches of semi-deciduous forest around ravines. We used belt transects in three different streams and irregular band transects in trails, together with pitfall traps, funnel traps, and litter quadrants. The richness of the Puyango Protected Forest represents a small percentage of the Ecuadorian reptile diversity, but covers much of the representative phylogenetic groups of tropical dry forests of the world. Sampling was effective to determine saurian diversity, but more sampling is needed to estimate snake diversity. Evidence of the presence of 21 species, divided into 10 families, was obtained; of which 14 are snakes (including a potential new species of the genus Epictia) and seven are lizards. Natural history is described for each species, including time and space use, and their conservation status is analyzed. The reptile community is characterized by a relative homogeneity over the vegetation remnants and the highest abundances correspond to saurian species.

Diversity of butterfly communities of a tropical rain forest of Bu Gia Map National Park in South Vietnam was studied in four different habitat types (the natural forest, the disturbed forest, the bamboo forest, and the stream sides in the forest) in December 2008 and April 2009. A total of 112 species with 1703 individuals of Papilionoidae (except Lycaenidae) were recorded. The proportion of rare species tends to decrease from the natural forest to the stream sides, while the proportion of common species tends to increase from the natural forest to the stream sides. The stream sides have the greatest individual number, while the disturbed forest contains the greatest species number. The bamboo forest has the least species and individual numbers. The stream side environment in the forest plays an important role in conserving butterfly abundance while the bamboo shows the poorest butterfly diversity.

Two lake sediment cores from Madre del Sur mountain range,Guerrero State, west-central Mexico were studied to examine the pastdynamics of the dry forest biome. Pollen, spores of coprophilousfungi, cyanobacteria and lithological changes are presented. The390-cm Tixtla core (1730'N, 99°24W, 1400 maltitude) represents the last 2700 cal. yr; the 340-cm Huitziltepeccore (17°45N, 99°28W, 1430 m altitude) representsthe last 2050 cal. yr. Pollen shows climate-dependent competitionbetween dry deciduous forest (with Asteraceae, Chamaesyce-type,Bursera, Euphorbia, Myrica and Lysiloma-Pithecellobium-type as main components) and moister(mesophyllous) forest (with Pinus, Quercus, Alnus and Juglans). Human impact on the environment is apparent duringthe entire record, as evidenced by crop cultivation (Zea mays,Amaranthus, Capsicum, Chenopodium), coprophilous fungi (Podospora-type and Sporormiella-type), deforestation (at Tixtla in particular) and lake eutrophication, ie, cyanobacteria blooms. Environmental change at both sites is summarized as follows. Period 1 (2700-2450 cal. yr BP): abundant dry deciduous forest and climate conditions drier than today. Period 2 (2450-1950 cal. yr BP): little change in proportions of dry deciduous and mesophyllous forest but floral composition of the forests differed between sites. Human occupation was low. Period 3 (1950-1550 cal. yr BP): dry deciduous forest decreased while mesophyllous forest increased, indicating more humid climatic conditions. Populations expanded significantly around 1950 cal. yr BP. Period 4 (1550-1070 cal. yr BP): maximum expansion of mesophyllous forest. Climate was more humid than today. Pre-Hispanic populations at Tixtla reached high numbers leading to deforestation and eutrophication. Period 5 (1070-c. 750 cal. yr BP): shows abundant mesophyllous forest and lowest proportions of dry deciduous forest. Climate continued to be humid. There is evidence of forest harvesting, crop cultivation and dense human population. Period 6 (c. 750-225 cal. yr BP): dry deciduous forest expanded and mesophyllous forest decreased. There was significant deforestation by pre-Hispanic people around Lake Tixtla. High population densities and frequent fires at both sites caused eutrophication of the lakes. Domesticated herbivores were introduced ∼ad 1500 and the presence of dung is reflected in the record of coprophilous fungi. Period 7 (the last 225 calendar years): the basins were used intensively by local people and their cattle. Dry deciduous forest continued to increase while mesophyllous forest decreased.

Late-winter habitat use by the Fisher, Pekania pennanti (Erxleben, 1777) in northwestern Saskatchewan was assessed in February 2009, 2011, and 2012. A total of 78 Fisher tracks were recorded over 60 300 m of snowshoe surveys. Fisher tracks were significantly less frequent than expected in Tamarack (Larix laricina [Du Roi] K. Koch) stands with > 40% crown closure and mainly 0–10 m trees (P < 0.05) and in open areas. Fishers used other habitat types equal to availability, including muskeg and coniferous, mixed, and deciduous forest stands. Maintaining mosaics of forest stands of different seral stages interspersed with muskeg would meet the late-winter habitat needs of Fishers in the Boreal Plains Ecozone of northwestern Saskatchewan.

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.

AbstractHabitat fragmentation creates habitat edges, and ecological edge effects can cause major changes in the ecology and distribution of many taxa. However, these ecological changes may in turn influence animal movements and lead to molecular edge effects and edge-related genetic structure, matters that are largely unexplored. This study aims to infer molecular edge effects and to test three possible underlying mechanisms in the Endangered golden-brown mouse lemur Microcebus ravelobensis, a nocturnal species in the dry deciduous forest of the Ankarafantsika National Park in north-western Madagascar. Mouse lemurs were sampled in one edge and two interior habitats in close proximity to each other (500–1,400 m) in a continuous forest. A total of 41 mouse lemur samples were genotyped with seven nuclear microsatellites, and a fragment of the mitochondrial control region was sequenced for all samples. The overall genetic diversity (allelic richness, heterozygosity, haplotype richness, nucleotide diversity) was lower in the edge habitat compared to the two interior sites and all subpopulations showed signals of relatively low genetic exchange and significant genetic differentiation between them despite the short geographical distances, supporting the local preference model. These findings can be interpreted as preliminary signals of a molecular edge effect and suggest the potential for local adaptation. They are highly relevant for the conservation of fragmented populations, because a further subdivision of already small populations may increase their vulnerability to stochastic demographic changes and collapse.
