Responding to forest degradation: altered habitat use by Dian's tarsier Tarsius dianae in Sulawesi, Indonesia
No full textAs most of the pristine forests of South-east Asia have been lost, the ability of its animal species to coexist with humans becomes increasingly important. Dian's tarsier Tarsius dianae, one of the smallest primates, lives in forests of central Sulawesi, Indonesia that are experiencing a dramatic increase in degradation by humans. To evaluate the effects of anthropogenic disturbance on tarsiers we used a comprehensive approach to estimate habitat suitability for these nocturnal insect-hunters. On four study plots along a gradient of human land-use we determined population densities, home range sizes, nightly path lengths and group sizes of T. dianae. In total we captured 71 individuals and radio-tracked 30 of these. In more undisturbed sites, population densities were high and travel distances small. We found the smallest home ranges in slightly disturbed forest. In a heavily disturbed plantation densities were low, and ranges and nightly path lengths were large. These results show that undisturbed and slightly degraded forests are the most suitable tarsier habitats, and that focusing on different population parameters could lead to differing conclusions about the suitability of particular habitats

Normal Forms for Rigid Hypersurfaces
No full textThis work was supported in part by the Polish National Science Centre (NCN) via the grant number 2018/29/B/ST1/02583Consider a -nondegenerate constant Levi rank rigid hypersurface in coordinates : The Gaussier-Merker model was shown by Fels-Kaup 2007 to be locally CR-equivalent to the light cone . Another representation is the tube . Inspired by Alexander Isaev, we study rigid biholomorphisms: The G-M model has 7-dimensional rigid automorphisms group. A Cartan-type reduction to an e-structure was done by Foo-Merker-Ta in 1904.02562. Three relative invariants appeared: , (primary) and (derived). In Pocchiola's formalism, Section 8 provides a finalized expression for . The goal is to establish the Poincar\'e-Moser complete normal form: with and . We apply the method of Chen-Merker 1908.07867 to catch (relative) invariants at every point, not only at the central point, as the coefficients , , . With this, a brige Poincar\'e Cartan is constructed. In terms of , the numerators of , , incorporate 11, 52, 824 differential monomials
Tarsius lariang Merker & Groves 2006
No full text10. Lariang Tarsier Tarsius lariang French: Tarsier du Lariang / German: Lariang-Koboldmaki / Spanish: Tarsero de Lariang Taxonomy. Tarsius lariang Merker & Groves, 2006, Gimpu (01° 38” S, 120° 02” E, 500 m above sea level), west of Lore-Lindu National Park, ¢.5 km north of the River Lariang, Central Sulawesi, Indonesia. This species is monotypic. Distribution. WC Sulawesi in the Lariang River Basin near the confluence with its tributary, the Meweh River, and extending N as far as Gimpu; the precise limits of its distribution have yet to be determined and it distribution may be much larger than what has been confirmed to date. It is known to be parapatric with Dian’s Tarsier (1. dentatus) on the E boundary ofits distribution. Descriptive notes. Head-body average 12-1 cm (males, n = 12) and 11-8 cm (females, n = 22), tail average 24 cm (males, n = 12) and 24-7 cm (females, n = 23); weight average 118 g (males, n = 12) and 102 g (females, n = 23). The Lariang Tarsier is a distinctive form, differentiated from tarsiers of mainland Sulawesi by its unique features of pelage, body proportions, skull, and vocalizations. It has very dark gray-buff pelage, lacking brown tones on the thighs. Its tail is very dark (often blackish) with a thick, black terminal tuft. It has well-marked thick, black paranasal stripes and well-marked black eye-rims. Hairs around the mouth are whitish, and there is a small bare spot at the base of each ear. The third digit of the hand is absolutely longer than in any other Sulawesi mainland tarsier. The Lariang Tarsier has a unique duet; distinguished from other members of the genus in that entire individual notes of the female song are upwardly frequency modulated. The Lariang Tarsier is the largest of the mainland Sulawesi tarsiers, and, compared to island forms, smaller only than the Great Sangihe Tarsier (7. sangirensis) of Sangir Island. Habitat. Primary and secondary lowland rainforest, mangrove forest, and forest gardens. The elevational range is believed to be up to 1100-1500 m. A study just southwest of Lore Lindu National Park near the village of Peana found Lariang Tarsiers in secondary growth of various stages of succession in a mosaic of shrub, forest, plantations, and gardens. Food and Feeding. The Lariang Tarsier eats mainly insects, along with some small vertebrates such as frogs and lizards. Breeding. A study of their genetic relatedness showed that most of the young were the offspring of the group adults, indicating a monogamous social and genetic mating system, but there is evidence for extrapair young in groups in which adult pairs exhibit close relationships (facultative polygyny). Activity patterns. There is no specific information available for this species, but it is nocturnal and arboreal. Movements, Home range and Social organization. Lariang Tarsiers live in small groups and show social and territorial behavior, including sleeping-site associations and morning duet calls, similar to other tarsiers on Sulawesi. Field observations found that ten of eleven social groups were composed of one adult male, one adult female, and up to two putative offspring. They shared sleeping sites and foraged together. The eleventh group in the study possibly had more than nine individuals. The social structure of the groups was not established, but they foraged in subgroups of varying composition and size and came together at dawn at the same sleeping site. Multiple individuals performed duet songs. Both males and females disperse to other groups. Status and Conservation. CITES Appendix II. Classified as Data Deficient on The IUCN Red List. Habitat loss and illegal logging are undoubtedly the major threats to populations of the Lariang Tarsier. They are also affected by agricultural pesticides, predation by dogs and cats, and capture for the pet trade. The Lariang Tarsier is believed to occur only below 1100-1500 m, but further surveys are needed to better understand its distribution and conservation status. It occurs in the Lore Lindu National Park. Bibliography. Driller et al. (2009), Groves (2001), MacKinnon & MacKinnon (1980a), Merker (2006b), Merker & Groves (2006), Merker et al.

Edge-decompositions of -edge-connected graphs into isomorphic copies of a fixed tree of size
No full textIn this paper, we show that every -edge-connected simple graph of size divisible by with minimum degree at least has an edge-decomposition into isomorphic copies of any given tree of size . Moreover, the minimum degree condition can be dropped for graphs with girth greater than the diameter of . These results improve two results due to Bensmail, Harutyunyan, Le, Merker, and Thomassé (2017) and Merker (2017) who gave a factorial upper bound on the necessary edge-connectivity
