Anthropogenic activities in Prince Edward Island (Canada) have created a mosaic of fragmented uneven-aged forests and agricultural and pasture lands, as well as large amounts of edge habitat. Although the mammalian fauna of the province is largely composed of small mammals, no previous study has investigated how they respond to habitat fragmentation. I surveyed 14 forest fragments in Prince Edward Island National Park to assess the effects of habitat fragmentation on the abundance and diversity of small mammals. A total of 897 small mammals from 11 different species were captured during 10 231 trap-nights. The most frequently captured species were the eastern chipmunk, Tamias striatus (53.5%), and the deer mouse, Peromyscus maniculatus (24.9%). Neither species richness, total population size, nor the Shannon–Wiener species-diversity index (H') was significantly associated with either fragment area or perimeter length. The results also indicated no difference in species diversity between linear fragments and other-shaped fragments. The only species showing a response to edge habitat was the eastern chipmunk. We concluded that future research in Prince Edward Island National Park should assess the abilities of small mammals and their predators to use edge habitats and agricultural fields.

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.

The study of non-volant small mammals was conducted at Kubah National Park (KNP), Sarawak for eight days between November 2018 until February 2019. The objective of this study was to determine the species diversity of non-volant small mammals at the highland (>750 – 805 m a.s.l.) and lowland (<200 m a.s.l.) at KNP. The elevation of Gunung Serapi is 911 m a.s.l. but the highest accessible area is at 805 m a.s.l.  The distance between two sampling sites is approximately 4.5 km. Humidity and temperature measurement were also recorded at both sites. A total of 50 cage traps were set up at the highland and 50 cage traps at the lowland. The baits that were used in this study were oil palm and banana. A total of 26 individuals from 11 species, eight genera and four families were captured. However, there is no significant difference in species diversity between low and high elevations because the elevation of KNP was not high enough to distinguish species that are highland or lowland specialist.

Habitat Variables

Human activities have fragmented amphibian habitats and affected amphibian diversity and distribution, but the ecology is poorly known. A four-year study assessed the diversity and distribution of amphibians in undisturbed and disturbed sites of the Kudremukh National Park (KNP), India. Iron-ore mining and associated activities in the KNP have induced habitat fragmentation. The disturbed sites had ranges of habitat variables clearly distinguishable from undisturbed sites. Thirty-six species of anurans and six species of caecilians have been recorded in the KNP and the total amphibian species richness represents 20% of the whole Indian amphibian fauna. Among these, 20 species were distributed in both disturbed and undisturbed sites, while 22 were found only in undisturbed sites indicating they may be threatened by further habitat fragmentation. Species diversity and richness formed two distinct groups clearly associated with disturbed and undisturbed habitats, respectively.

Although lists of spider species have been compiled for all of Canada’s provinces and territories, the spider fauna of Prince Edward Island (PEI) is poorly known. Based on the efforts of citizen scientists, naturalists, and scientists on PEI and researchers at the Centre for Biodiversity Genomics, we present the first comprehensive list of spider species on the island, increasing the known number from 44 to 198. The Centre for Biodiversity Genomics conducted intensive collection in Prince Edward Island National Park; Nature PEI citizen scientists and naturalists contributed specimens from across the island from several different habitats. This provincial list is dominated by the araneoid families, Linyphiidae, Theridiidae, and Araneidae, with 55, 27, and 22 species, respectively. Several non-native species, such as the theridiid Eurasian False Black Widow Spider (Steatoda bipunctata (L.)) and the araneid Red-sided Sector Spider (Zygiella atrica (C.L. Koch)), have been collected in several locations on the island, suggesting that they are well established. This work highlights the effectiveness of collaboration among citizen scientists, naturalists, and professional researchers to further our knowledge of species diversity and distributions.

A total of 16 000 trap-nights was employed over eleven months to examine the influence of burning on small mammal populations in two major veld-types of the Kruger National Park. Four burning treatments (control, annual August burning, triennial August and April burning) were examined in detail and the following parameters determined: small mammal species composition, population density, biomass and species diversity. The control treatment had a high, stable small mammal density, biomass and diversity; the annual burning treatment had a low diversity and was dominated by Tatera leucogaster. The triennial burning treatments showed a cycle of species composition from domination by T. leucogaster following burning, through domination by other rodent species to domination by Crocidura hirta at the end of the cycle. The distributions and movements of the small mammals can be explained in terms of cover and litter preferences.

Most of the previous records of the freshwater molluscs from the Kruger National Park date back prior to and up to 1966. On account of several droughts between 1966 and 1995 it was decided to do a survey of the freshwater mollusc population in 1995 to evaluate the effect of these droughts. The traditional mollusc intermediate hosts were also screened for trematode parasites to establish whether or not they were infected. No infected molluscs were found. Eight of the 19 species reported up to 1966 were not found during the 1995 survey. Three new mollusc species were collected in 1995. The consequences of the drought are clearly visible when the species diversity found in the dams in the 1995 survey, is compared to what was previously recorded.
