The Indonesian island of Sulawesi harbors a highly endemic and diverse fauna sparking fascination since long before Wallace's contemplation of biogeographical patterns in the region. Allopatric diversification driven by geological or climatic processes has been identified as the main mechanism shaping present faunal distribution on the island. There is both consensus and conflict among range pa...

Because island communities are derived from mainland communities, they are often less diverse by comparison. However, reduced complexity of island communities can also present ecological opportunities. For example, amphibian diversity on Sulawesi Island is lower than it is in the Philippines, but Sulawesi supports a surprising diversity of Sulawesi fanged frogs (Limnonectes). Here we examine mo...

In the Spermonde as in the other main island groups around Sulawesi, seagrass and coral ecosystems are intimately linked ecologically and overlap extensively on the shallow water shelves surrounding most islands. One keystone species living in these shallow waters is the dugong (Dugong dugon). Officially fully protected under Indonesian Law (PP7/1999), published data on dugongs in the islands a...

The complex geological history of the Indonesian island Sulawesi has shaped the origin and subsequent diversification of its taxa. For the endemic freshwater snail Tylomelania a vicariant origin from the Australian margin has been hypothesized. Divergence time estimates from a mtDNA phylogeny based on a comprehensive island-wide sampling of Tylomelania fit regional tectonic constraints and supp...

This data article is related to the research article entitled "Origin and intra-island diversification of Sulawesi endemic Adrianichthyidae" by Mokodongan and Yamahira [1]. In this data article, we present phylogenetic trees of Sulawesi adrianichthyids separately reconstructed using mitochondrial (cytochrome b: cyt b and NADH dehydrogenase subunit 2: ND2) and nuclear (tyrosinase) sequences. We ...

A new species of Cyrtodactylus is described from Sulawesi and the adjacent island of Kabaena, Indonesia. This new species is the largest Cyrtodactylus known from Sulawesi and differs from all other congeners by the absence of precloacal and femoral pores, enlarged femoral scales or pubic groove; medium to large size (up to 113.6 mm snout–vent length) and dark purple dorsum with irregular dark b...

the distribution, body size, and egg diameter and volume of ovigerous blue swimming crabs, portunus pelagicus , were examined according to habitat type and egg color in lasongko bay, central buton, indonesia between april 2013 and march 2014. ovigerous female crabs were sampled using gillnets and traps at seven stations. based on the results, the ovigerous female crabs with yellow to dark gray ...

Three new species and one new subspecies are described: Scamandra lumawigi sp. n. (Luzon, Philippines), S. huangi sp. n. (Taliabu Island off Sulawesi), S. vanvyvei sp. n. (Sulawesi) and S. vanvyvei pelengana ssp. n. (Peleng Island off Sulawesi). The status of Scamandra mucorea Gerstaecker, 1895 is revised and the species is no more considered a subspecies of S. hermione Stål, 1864. The new name...

The Sunda Arc forms an almost continuous chain of islands and thus a potential dispersal corridor between mainland Southeast Asia and Melanesia. However, the Sunda Islands have rather different geological histories, which might have had an important impact on actual dispersal routes and community assembly. Here, we reveal the biogeographical history of hyperdiverse and flightless Trigonopterus ...
