Abstract: The probability of existence or not of local extinctions of six species of carnivorous mammals was analyzed by ordering the species composition in nested subsets in 7 fragments of forest habitats in the Coastal Mountains in the Araucanía Region, in southern Chile. Nested Temperature Calculator (NTC) and BINMATNEST computer programs were used to process the results. The first software provided a temperature in the archipelago of 28.21 degree Celsius, whereas the second program showed a nesting temperature of 16.58 degree Celsius. The computer software used in this study suggest that there is no nesting pattern at the level species composition of carnivorous mammal assemblage in the evaluated area, which may be due to the habitat use characteristics of the different carnivorous mammals studied here.

Distribution of butterfly species along the latitudinal and habitat gradients of the Western Ghats was studied. The Western Ghats was divided into 14 latitude zones and the species diversity in each latitude zone, along with habitats of their occurrence, were studied using the data from literature survey for the entire Western Ghats as well as data from personal observations in the areas between 14°N to 20°N latitudes. Out of 334 species recorded from the Western Ghats, 58 species were found in all latitudinal zones, while 5 species were reported in only one latitudinal zone. Further, southern Western Ghats consisted of more number of species and more number of genera as compared to northern Western Ghats. Latitudinal zones between 10°N to 12°N had most of the Western Ghats endemic species. Habitat wise distribution of species revealed three significant clusters grossly separated by the level of human disturbance. Evergreen forest habitats supported maximum number of species endemic to the Western Ghats.

Abundance And Diversity

Frugivorous butterflies were studied in a set of forested islands (0.1 to 1.15 ha) in a reservoir in eastern Venezuela to investigate the effects of fragmentation and the resulting isolation on their abundance, diversity and species composition. While some islands showed reduced abundance and species diversity in comparison to unfragmented (or control) sites, others did not. Isolation status affected both butterfly abundance and diversity. Islands located close to their colonizing sources (0.1–1 km) tended to support similar densities of butterflies but lower numbers of species in comparison to control sites. Far fragments (1–3 km from their colonizing sources) tended to harbour lower butterfly densities in comparison to control sites but undiminished numbers of species. Species composition varied significantly between control sites and islands and amongst control sites, near islands and far islands. Interspecific differences were observed in species' responses to fragmentation. Charaxines, medium-sized satyrines, morphines and brassolines may be vulnerable to extinction after habitat fragmentation while small-sized satyrines may be relatively resistant. Observations during the dry season indicate that butterfly species may exist as mainland-island metapopulations in Lago Guri, in which small habitat fragments require recolonization every year from source populations in large islands and mainland habitat.

A sampling of butterfly species composition and status is carried out in the sunny and shaded habitats of Cadaclan, San Fernando, La Union Botanical Gardens (LUBG) utilizing transection and standard collection practices. This study is the first comprehensive account of butterflies in the area.    Times for the collection were from 09:00 to 15:00 hours from 2012-2014 and yielded a total of 104 species during the sampling period.  Data on the species composition revealed six families out of 104 species under 66 genera and a new distribution record and several respective ecological preferences.  Percentage distribution by family indicate the following: Papilionidae, 24 (22.85%), Pieridae, 47 (47.70%), Nymphalidae, one (0.95%), Hesperiidae, 15 (14.29%), Riodinidae one (0.95%) and Lycaenidae, 16 (15.24%). Local status reveals 80 common, 23 very common, and one rare species. The National Assessment indicates 65 (62.5%) common, 2 (1.92%) rare, 1 (0.95) very rare, 12 (11.59 %) common endemic, 4 (3:85%) very rare endemic, 1 (0.95%) Luzon endemic, and 1 (0.95%) no experience and 1 (0.95%) new record Jamides cyta koenigswateri with only known distribution in Mindoro. Similarity of species composition showed Si=71% which suggests two separate and diverse habitat types. Additionally, variables such as temperature, vegetation types and elevation affect species composition and abundance. It is to be noted that collection times do not allow for crepuscular species and as such will skew the data but not significantly due to few species being categorized under this heading. Keywords - Butterfly, species composition, transect walk sampling, opportunistic sampling, Luzon, Philippines

Three years of sampling (2007-2009) of adult mosquitoes in the area of Vojvodina (Serbia) by dry ice baited CDC traps has provided information on mosquito species composition, prevalence and seasonal activity. A total of 58,247 adult mosquitoes were collected comprising twenty species belonging to the following genera: Anopheles Meigen (Diptera: Culicidae), Aedes Meigen, Culex L, Culiseta Felt and Mansonia Blanchard. The seven most common species collected during this study were: Culex pipiens L. complex (35.6%), Aedes vexans (Meigen) (33.4%), Aedes sticticus (Meigen) (15.2%), Anopheles maculipennis Meigen complex (4%), Mansonia richiardii (Ficalbi) (3.8%), Aedes cinereus Meigen (3.6%), Aedes pulchritarsis (Rondani) (3%) which made up 98% of all specimens. Seasonal population dynamics differed between years and between mosquito species in relation to wetland, urban and forest habitats, and was primarily influenced by the water level of the Danube, Sava and Tisa rivers, precipitation and temperature.

The Impact

Roads may have an important negative effect on animal dispersal rate and mortality and thus the functioning of local populations. However, road verges may be surrogate habitats for invertebrates. This creates a conservation dilemma around the impact of roads on invertebrates. Further, the effect of roads on invertebrates is much less understood than that on vertebrates. We studied the effect of roads on butterflies by surveying abundance, species richness and composition, and mortality in ten grassland patches along high-traffic roads (∼50–100 vehicles per hour) and ten reference grassland patches next to unpaved roads with very little traffic (<1 vehicle per day) in southern Poland. Five 200-m transects parallel to the road were established in every grassland patch: at a road verge, 25 m from the verge, in the patch interior, and 25 m from the boundary between the grassland and field and at the grassland-arable field boundary. Moreover, one 200-m transect located on a road was established to collect roadkilled butterflies. The butterfly species richness but not abundance was slightly higher in grassland patches adjacent to roads than in reference grassland patches. Butterfly species composition in grasslands adjacent to roads differed from that in the reference patches. Proximity of a road increased variability in butterfly abundances within grassland patches. Grassland patches bordering roads had higher butterfly abundance and variation in species composition in some parts of the grassland patch than in other parts. These effects were not found in reference grassland patches, where butterfly species and abundance were more homogenously distributed in a patch. Plant species composition did not explain butterfly species. However, variance partitioning revealed that the presence of a road explained the highest proportion of variation in butterfly species composition, followed by plant species richness and abundance in grassland patches. Road mortality was low, and the number of roadkilled butterflies was less than 5% of that of all live butterflies. Nevertheless, the number and species composition of roadkilled butterflies were well explained by the butterfly communities living in road verges but not by total butterfly community structure in grassland patches. This study is the first to show that butterfly assemblages are altered by roads. These results indicate that: (1) grassland patches located near roads are at least as good habitats for butterflies as reference grassland patches are, (2) roads create a gradient of local environmental conditions that increases variation in the abundance of certain species and perhaps increases total species richness in grassland patches located along roads, and (3) the impact of roads on butterflies is at least partially independent of the effect of plants on butterflies. Furthermore, (4) the direct impact of road mortality is probably spatially limited to butterflies living in close proximity to roads.
