The Red-necked keelback, Rhabdophis subminiatus (Schlegel, 1837), occurs in Indonesia on Java, Sumatra, Nias, and possibly Sulawesi. This species exhibits a suite of defensive displays, including body flattening, neck flattening, neck arching, neck butting, and dorsal-facing postures. Body flattening enlarges the body profile to intimidate predators, while neck flattening accentuates the bright red coloration of the neck, a visual warning linked to the location of the nuchal glands.

Ophiophagy in the saw-scaled viper (Echis carinatus) from the UAE

The saw-scaled viper, Echis carinatus (Schneider, 1801), is a widespread venomous snake found across arid and semi-arid regions of the Middle East and South Asia. It is a generalist predator, known to feed predominantly on arthropods (particularly scorpions and centipedes), small lizards, rodents, and occasionally amphibians, and generally exhibits opportunistic feeding patterns typical of Old-World vipers. Despite a well-documented dietary breadth, no prior observations or records of ophiophagy (snake-eating behavior) exist for this species.

Book Review: Spesies Apakah Itu? [What Species Is That?]

Indonesia is known as a megadiverse country with an extraordinary richness of biological diversity. However, the public’s understanding of what species are, how they are identified, and their primary importance for life and conservation remains limited. In this context, the book Spesies Apakah Itu? Menjawab Pertanyaan Pertama dari Penggemar Alam Sejati is a relevant and urgent work. The book “Spesies Apakah Itu? Menjawab Pertanyaan Pertama dari Penggemar Alam Sejati” was written by a team of scientists and biodiversity observers, and edited by Mochamad Indrawan, Anargha Setiadi, Wellyzar Sjamsuridzal, and Himmah Rustiami. This book combines scientific, participatory, and cultural approaches to explain the meaning of species and the importance of community involvement in conservation efforts.

A COMPREHENSIVE BIBLIOMETRIC ANALYSIS OF OTOLITH RESEARCH ON EELS

Abstract
Otoliths serve as biogenic archives that reveal age, growth, habitat shifts, and environmental histories of fishes. We analyzed 94 years of eel otolith research (374 Scopus-indexed papers, 1930–2023) and visualized co-authorship and keyword networks with VOSviewer. Output rose sharply after 2000, dominated by Japan (26%), Taiwan (12%), and France (11%), forming dense clusters of collaboration among Japan, Taiwan, France, and North America. Research themes progressed from early age and growth studies to otolith microchemistry, migration and recruitment dynamics, and, more recently, to conservation, contaminants, and climate change. Core keywords (“otolith,” “age,” “growth,” “migration”) persist, with newer emphases on phenotypic plasticity and restoration. Tropical anguillids remain underrepresented relative to temperate species, non-anguillid eels appear sporadically, and several life stages—especially leptocephali and yellow eels—are unevenly studied. This synthesis benchmarks global eel otolith scholarship and identifies priorities for cross-regional collaboration and conservation-linked research.

MAPPING THE SCIENTIFIC LANDSCAPE OF ENVIRONMENTAL POLLUTION RESEARCH: A BIBLIOMETRIC APPROACH
Randi Mulianda*, W. Wulandari, Novia Qomariyah, Andi Ella, Yenni Yusriani, Ahmad Sofyan & I Nyoman G. Darma
*Corresponding author. E-mail: randimulianda@gmail.com
Abstract
This bibliometric analysis maps global research on the impacts of environmental pollution on biodiversity from 1990–2024. Using Scopus data processed with VOSviewer, Bibliometrix, and OpenRefine, the study identifies major publication trends and thematic structures. Research output surged after 2015, mirroring rising concern about ecosystem degradation. The United States and China dominate publication volume and collaboration networks. Core themes include heavy metals, microplastics, and persistent organic pollutants, with increasing focus on bioaccumulation, biomagnification, and ecosystem health risks. Thematic evolution shows a transition toward interdisciplinary and risk-oriented studies. Findings highlight geographic and funding disparities, underscoring the need for broader international participation. Despite database and keyword limitations, this study offers insights into how scientific communities respond to pollution-driven biodiversity loss and provides an evidence base for policy, education, and coordinated global research.
