We examined the influence of fruit availability and habitat disturbance, including past and recent forest fires, on an assemblage of hornbills over a four-month period in the Bukit Barisan Selatan National Park, Sumatra. The assemblage is dominated by Wreathed Hornbills Aceros undulatus (7.5 birds/km2), followed by Bushy-crested Hornbills Anorrhinus galeritus (3.05 birds/km2), Rhinoceros Hornbills Buceros rhinoceros (2.6 birds/km2), and Helmeted Hornbills Buceros vigil (1.9 birds/km2). Overall densities for each species were consistent with estimates from other South-East Asian sites but densities varied temporally and spatially, even for territorial species. We speculate that Rhinoceros and Helmeted Hornbills may exhibit facultative territoriality or they may not be territorial at this site. We found a positive relationship between temporal variability in hornbill numbers and the availability of ripe fruits. All hornbills, especially Rhinoceros and Bushy-crested Hornbills, tended to avoid highly disturbed areas; these areas had a lower than expected number of fruiting trees in five important hornbill diet families. Densities of Bushy-Crested, Rhinoceros, and Helmeted Hornbills declined from 28 to 63% in the post-burn surveys. Wreathed Hornbills, however, increased slightly in the post-burn surveys, possibly because they were nesting there at the time. Movement of hornbills between disturbed and primary forest habitat may enhance regeneration of disturbed areas if hornbills are transporting viable seeds.

Monitoring forest cover to find out deforestation activities in a national park serves as an important task. This study aims to analyze forest cover changes in Gunung Palung National Park from 1989 to 2018. The method employs visual interpretation aided by supervised classification with the maximum likelihood method. Remote sensing data involved 18 Landsat images from 1989 to 2018 path/row 121/61. The results indicated that Gunung Palung National Park had 97,148 hectares of primary forest losing its 10% of its forest (since 1989). The primary forest decreased to 72,684 hectares in 1997 and 69,851 hectares in 2018. To date, primary forest cover has been found stable with secondary forests reaching to 25,050 hectares occupying 26% of Gunung Palung National Park area. Deforestation in Gunung Palung National Park was due to illegal logging and forest fires as a result of El Nio influence. The results of the analysis informed that there was an insignificant deforestation in Gunung Palung National Park during in the period of 2016 - 2018. In sum, conservation programs are encouraged to sustain, despite a decline in deforestation activities at Gunung Palung National Park.

Strangler fig density varied considerably in the evergreen forest of Karian Shola National Park, southern India, with 11 individuals ha−1 in an open trail area and 5.6 individuals ha−1 within the primary forest area. The index of light level was assessed by estimating the percentage of upper canopy cover along the longitudinal centre of ten, 500-m × 20-m plots in each of the two areas of the evergreen forest. However, the increase in strangler fig density was not correlated to light levels but was significantly correlated to the numbers of their main host species in the two areas. In Karian Shola National Park, strangler figs occurred predominantly on a few host species with 20 and 50% of strangler figs growing on Vitex altissima, Diospyros bourdilloni and Eugenia/Syzygium spp. in the primary forest and trail areas respectively. Both young and established strangler figs were recorded mainly on larger individuals of their host trees indicating that older host trees are likely to be more suitable for the germination and establishment of strangler figs. The reason for the above could be the higher incidence of humus-filled and decaying regions in the older host trees which would provide an assured supply of nutrients for the establishing strangler fig.

AbstractSubmitted Manuscript 2016. Territorial animals share a variety of common resources, which can be a major driver of conspecific encounter rates. We examine how changes in resource availability influence the rate of encounters among individuals in a consumer population by implementing a spatially explicit model for resource visitation behavior by consumers. Using data from 2009 and 2010 in Etosha National Park, we verify our model's prediction that there is a saturation effect in the expected number of jackals that visit a given carcass site as carcasses become abundant. However, this does not directly imply that the overall resource-driven encounter rate among jackals decreases. This is because the increase in available carcasses is accompanied by an increase in the number of jackals that detect and potentially visit carcasses. Using simulations and mathematical analysis of our consumer-resource interaction model, we characterize key features of the relationship between resource-driven encounter rate and model parameters. These results are used to investigate a standing hypothesis that the outbreak of a fatal disease among zebras can potentially lead to an outbreak of an entirely different disease in the jackal population, a process we refer to as indirect induction of disease.

The occurrence of forest fires in the Muddus National Park (area, 50 000 ha), just north of the Arctic Circle in northern Sweden, was investigated on 75 separate sample plots. Between 1413 and the present, evidence of 47 fire years was obtained by dating the fire scars on living Scots pines (Pinus sylvestris), the oldest of which had germinated in 1274. The fire traces found on the sample plots were fire scars on living or dead trees or charcoal fragments in the humus layer. Plots lacking all traces of former forest fires were mainly those situated on sites surrounded by extensive mires. Forest fires were shown to have occurred in the five different types of forest investigated. The commonest frequencies of fires in the pine forests occurred with the interval 81–90 years, while the mean frequency was 110 years. The mean interval of time elapsed since the last forest fire occurred in the pine forests was 144 years. Some of the major fire years in the Muddus area coincide with forest fires in other parts of northern Sweden, in the taiga of western Russia, and in central Siberia.

AbstractA survey of diurnal primate populations was carried out in Odzala National Park, Republic of the Congo, over 3 months in 1994 and 2 months in 1995. The park contains a high diversity and species-specific abundance of primates, and has the highest number of diurnal primates (10 species) in the forest block of Central Africa. Eight species of monkey: greater whitenosed monkey Cercopithecus nictitans, moustached monkey Cercopithecus cephus, crowned guenon Cercopithecus pogonias, De Brazza's monkey Cercopithecus neglectus, talapoin Miopithecus talapoin, white-cheeked mangabey Cercocebus albigena, agile mangabey Cercocebus galeritus and guereza Colobus guereza, as well as gorilla Gorilla g. gorilla and chimpanzee Pan t. troglodytes were sighted in the survey. Monkey species richness was highest in dense inundated forest and thicket, with all eight species occurring in these habitats, whereas only four species were found in terra firma forest (consisting of the park's two main habitats, open-canopy Marantaceae forest and closed-canopy primary forest). Three of the four species (C. nictitans, C. cephus and C. albigena) present in terra firma forest were most abundant in closed-canopy primary forest (1.4,1.0 and 0.6 groups per km, respectively) while the fourth (C. pogonias) was most abundant in open-canopy Marantaceae forest. Gorilla nests were most abundant in open-canopy Marantaceae forest (12.1 nests per km), while chimpanzee nests were mostly found in closed-canopy primary forest and Marantaceae forest (14 and 12 nests per km, respectively). Odzala has the highest recorded densities of western lowland gorilla (mean = 5.4 individuals per sq km) and chimpanzee (mean = 2.2 individuals per sq km) in Central Africa. The high densities of gorillas and chimpanzees may be a result of the high productivity of the forest and low poaching pressure. Conservation measures to ensure the maintenance of conditions in the area, such as educational programmes, are suggested.
