ABSTRACT Diurnal raptors were counted during their southward migration in autumn of 2019 at Kenting National Park, southern Taiwan, an important hawkwatch site along the East-Asian Oceanic Flyway. Observations were conducted from 1 September to 31 October 2019 in the morning hours, but the observation period was extended to 1400 H whenever large numbers of raptors passed the site before noon. A total of 329,559 individuals of 14 migratory raptor species was recorded. The Chinese Sparrowhawk (Accipiter soloensis) and Gray-faced Buzzard (Butastur indicus) made up 78.3% (257,971 birds) and 21.6% (71,045 birds) of the total, respectively. The number of Chinese Sparrowhawks increased significantly when we extended the survey duration from 1200 H to 1400 H (paired t-test, t = 2.44, P = 0.04), but the number of Gray-faced Buzzards did not (t = 1.94, P = 0.09). Thus, Chinese Sparrowhawks may continue passing the site en route to the Philippine Islands in the afternoon hours, whereas Gray-faced Buzzards usually stop migrating in early afternoon, at least under certain conditions. How prevailing wind conditions along the East-Asian Oceanic Flyway in autumn shape the different migratory strategies of these two hawk species requires further study.

This paper presents the results of field work conducted between 1994 and 1996 to establish the occurrence, and population, breeding and conservation status of bats in and around Kenting National Park, southern Taiwan. Of the 20 bat species that occur in Taiwan, Kenting National Park and its vicinity harbour eight species; three are endemic to Taiwan and two are endemic subspecies. Six of the eight species roost in natural caves and man-made tunnels. Two species of forest bats were captured during mist-netting. The most predominant species were the horseshoe bat Rhinolophus monoceros and the common bent-winged bat Miniopterus schreibersii. The major threat for the cave-dwelling bats around Kenting is the closure of cave entrances by farmers. Recommendations are given for conserving the bats and their habitats in Taiwan.

Abstract During a survey of termite-associated nematodes in southern Taiwan (Kenting National Park), two species of Poikilolaimus, Poikilolaimus cf. floridensis and an undescribed species, were isolated from termites in the family Kalotermitidae. The undescribed species is morphologically observed, described and figured herein as P. carsiops n. sp. The new species is characterised by an unusual cross-shaped stomatal opening formed by two well developed dorsal and two subventral lip sectors, each with a triangular flap and two vestigial lateral lip sectors lacking a flap, and several other morphological characters. Based upon morphology and molecular phylogenetic analysis, P. carsiops n. sp. is closest to P. floridensis; i. e., these two species share a plesiomorphic regular cuticle and short tail in both males and females, and a lack of metastegostomatal teeth or denticle. In the molecular phylogenetic analysis, P. carsiops n. sp. and P. floridensis formed a well-supported clade which was clearly separated from, but monophyletic with, a clade that includes the other Poikilolaimus species. Because both P. carsiops n. sp. and P. floridensis have been isolated only from the kalotermitid termites, the P. floridensis/P. carsiops n. sp. clade is considered to be specialised with dry wood and damp wood termites (Kalotermitidae).

Abstract Background Glossina (tsetse flies) biologically transmit trypanosomes that infect both humans and animals. Knowledge of their distribution patterns is a key element to better understand the transmission dynamics of trypanosomosis. Tsetse distribution in Rwanda has not been well enough documented, and little is known on their current distribution. This study determined the current spatial distribution, abundance, diversity, and seasonal variations of tsetse flies in and around the Akagera National Park. Methods A longitudinal stratified sampling following the seasons was used. Biconical traps were deployed in 55 sites for 6 consecutive days of each study month from May 2018 to June 2019 and emptied every 48 h. Flies were identified using FAO keys, and the number of flies per trap day (FTD) was used to determine the apparent density. Pearson chi-square (χ2) and parametrical tests (t-test and ANOVA) were used to determine the variations between the variables. The significance (p < 0.05) at 95% confidence interval was considered. Logistic regression was used to determine the association between tsetse occurrence and the associated predictors. Results A total of 39,516 tsetse flies were collected, of which 73.4 and 26.6% were from inside Akagera NP and the interface area, respectively. Female flies accounted for 61.3 while 38.7% were males. Two species were identified, i.e. G. pallidipes [n = 29,121, 7.4 flies/trap/day (FTD)] and G. morsitans centralis (n = 10,395; 2.6 FTD). The statistical difference in numbers was significant between the two species (p = 0.000). The flies were more abundant during the wet season (15.8 FTD) than the dry season (4.2 FTD). Large numbers of flies were trapped around the swamp areas (69.1 FTD) inside the park and in Nyagatare District (11.2 FTD) at the interface. Glossina morsitans was 0.218 times less likely to occur outside the park. The chance of co-existing between the two species reduced outside the protected area (0.021 times). Conclusions The occurrence of Glossina seems to be limited to the protected Akagera NP and a narrow band of its surrounding areas. This finding will be crucial to design appropriate control strategies. Glossina pallidipes was found in higher numbers and therefore is conceivably the most important vector of trypanosomosis. Regional coordinated control and regular monitoring of Glossina distribution are recommended. Graphic Abstract

Insight Into

Fish remains from Late Iron Age sites in the Transvaal are relatively scarce. It seems as if the people did not utilize the riverine resources extensively. Therefore the unique assemblage of large numbers of fish bones on a Late Iron Age site, provides some insight into the fish population of a section of the Letaba River a few hundred years ago. The presence of other faunal remains provides some information on prehistoric utilization of the environment in general. Hunting strategies and aspects of herding can also be deduced from the faunal remains.
