Interference avoidance by wild ungulates at a mineral lick, Central Kalimantan

Mineral licks are small, mineral-rich sites within forests that wildlife visit to supplement their mineral intake by licking or consuming soil. These licks are essential sources of minerals such as sodium, potassium, calcium, and magnesium, which support osmoregulation, toxin neutralization, and the development of bones and muscles. Due to mineral deficiencies in plant foliage, wild herbivores often resort to geophagy. The Belantikan Hulu area, within the Arabela landscape of the Schwaner Mountains in Central Kalimantan, Indonesia, comprises lowland forest dominated by Dipterocarpaceae species such as Dipterocarpus fagineus and Shorea laevis, along with Eusideroxylon zwageri. There are several active mineral licks in this landscape.

Seahorses and pipefishes of Sri Lanka (Teleostei: Syngnathidae)

Sri Lanka, situated within the biodiversity-rich Indo-Pacific, is recognized as a hotspot for marine and freshwater fish diversity. Although numerous new teleost species have been described from the island in recent decades, the family Syngnathidae, which includes seahorses, pipefishes, and pygmy pipehorses, remains poorly documented. Despite early taxonomic contributions, such as those by Duncker (1910), who described the pipefish species Siokunichthys southwelli and Microphis ocellatus from ‘Ceylon’, modern systematic studies on Sri Lanka’s syngnathid fauna are lacking. Given the morphological complexity of this group and the potential for cryptic species, a comprehensive taxonomic synthesis is overdue. Accurate field identification of syngnathid species in Sri Lanka is further complicated by the lack of region-specific diagnostic tools and the morphological conservatism typical of the group. Foundational works, including Dawson (1985), provide broad Indo-Pacific coverage but are not tailored to the local fauna.
Water bodies are vital for sustaining life. India has about 2.42 million water bodies, with 97.1% in rural and 2.9% in urban areas; ponds make up 59.5% of these. Gujarat has 54,069 water bodies, of which only 8.71% are ponds. In Gujarat, 98.3% lie in rural areas, where ponds account for 7.9%, while in urban areas, ponds make up 56.3%. Gujarat State of India harbours 615 species of birds. Avifaunal diversity and abundance vary seasonally based on food availability, habitat characteristics, and breeding site preferences. Urbanization and population growth lead to habitat fragmentation, altered vegetation, and reduced natural resources, affecting bird diversity, abundance, and distribution. Urban expansion causes biodiversity loss, native species decline, and increased extinction rates. Bird responses vary based on dietary guilds, nesting, and roosting habits, and even minor habitat changes can impact their behaviour. Previous studies confirmed that urbanization impacts avian species abundance, richness, diversity, and distribution.
The genus Steatoda Sundevall, 1833 (Family Theridiidae) is represented by 6 species in India. Steatoda erigoniformis has been previously reported from Maharashtra and Rajasthan. Here we provide the first report from Gujarat State. The specimens were hand-collected and studied under a Zeiss Stemi 508 stereomicroscope, photographed using an Axiocam Erc 5s microscopic camera. The species was identified based on Levy & Amitai (1982) and Tripathi et al. (2023). The specimens have been deposited in the Department of Zoology, R.R. Lalan College, Bhuj-Kachchh, Gujarat, India.

Two newly recorded gobiid fishes (Sicyopus spp.) from Sumatra, Indonesia

Fishes of the family Gobiidae, with an incredible diversity of over 2,000 species across 250 genera, represent one of the most diverse groups of vertebrates. The subfamily Sicydiinae is a speciose group of gobies that occupy tropical to temperate island streams in Indo-Pacific regions. Within this subfamily, the genus Sicyopus Gill, 1863, consists of eight valid species. This genus can be recognised by possessing widely spaced, mostly recurved, conical teeth on both the premaxillary and dentary jaws. Additionally, the premaxillary ascending process is narrowly tipped dorsally, and the tongue is free from the mouth floor. Recent ichthyofaunal surveys conducted in the streams of western Sumatra resulted in the collection of several specimens belonging to two distinct Sicyopus species. These findings represent novel records and significant range extensions for Sicyopus spp. within the Indonesian archipelago. Brief descriptions of the two newly recorded species based on the current collected specimens, as well as morphological character comparisons, are presented in this study..
