摘要

兵蟹 Dotilla myctiroides 在沙滩上挖掘洞穴,从沉积物中汲取营养。本研究在泰国 Trang 省 Kantang 县 Koh Libong 分区 Libong 岛 Laem Juhoi 海滩调查了这种兵蟹的洞穴形态。通过向洞穴中注入熔融石蜡,对随机选择的洞穴进行了检查。收集在洞穴中发现的螃蟹并测量其躯干长度。对完整洞穴铸模的形状进行鉴定,并记录洞穴铸模的各种形态特征。共鉴定出 84 个洞穴,均为工字形或单管洞穴。根据洞穴开口直径将洞穴分为两组:<12 毫米组和≥12 毫米组。洞穴开口直径从 7.50 毫米到 20.10 毫米不等,洞穴底部末端直径从 8.40 毫米到 21.00 毫米不等,洞穴总长度从 27 毫米到 206 毫米不等。两组的躯干长度与洞穴开口直径有显著相关性(p<0.05)。此外,洞穴开口直径<12毫米组的洞穴距离明显大于洞穴开口直径≥12毫米组(p<0.05)。观察到的洞穴距离差异表明,生态和行为因素的潜在差异会影响不同大小类别的D. myctiroides的洞穴形态。

Burrow Morphological Characteristics of Soldier Crab (Dotilla myctiroides) on the Libong Island, Koh Libong Subdistrict, Kantang District, Trang Province, Thailand
Dotilla myctiroides, the soldier crab, digs burrows in sand flats and extracts nutrients from sediment. The present study investigated the burrow morphology of this soldier crab, at Laem Juhoi Beach, Libong Island, Koh Libong Subdistrict, Kantang District, Trang Province, Thailand. Randomly selected burrows were examined by injecting molten paraffin into them. The crab found inside a burrow was collected and measured for its carapace length. The shapes of the complete burrow casts were identified, and various morphological characteristics of the burrow casts were recorded. A total of 84 burrows were identified, all of them were the I-shaped or single-tube burrows. The burrows were categorized into two groups based on the burrow opening diameter: the <12 mm group and the ≥12 mm group. The burrow opening diameter ranged from 7.50 to 20.10 mm while the end diameter at the burrow bottom ranged from 8.40 to 21.00 mm, and the total length of the burrows ranged from 27 to 206 mm. The carapace length showed a significant correlation (p<0.05) with the burrow opening diameter in both groups. Additionally, the burrow opening with a diameter <12 mm group had significantly greater hole distances than the burrow opening with a diameter ≥12 mm group (p<0.05). The observed variations in hole distances suggest potential differences in ecological and behavioral factors that influence the burrow morphology of D. myctiroides in distinct size categories.

期刊介绍: The Environment and Natural Resources Journal is a peer-reviewed journal, which provides insight scientific knowledge into the diverse dimensions of integrated environmental and natural resource management. The journal aims to provide a platform for exchange and distribution of the knowledge and cutting-edge research in the fields of environmental science and natural resource management to academicians, scientists and researchers. The journal accepts a varied array of manuscripts on all aspects of environmental science and natural resource management. The journal scope covers the integration of multidisciplinary sciences for prevention, control, treatment, environmental clean-up and restoration. The study of the existing or emerging problems of environment and natural resources in the region of Southeast Asia and the creation of novel knowledge and/or recommendations of mitigation measures for sustainable development policies are emphasized. The subject areas are diverse, but specific topics of interest include: -Biodiversity -Climate change -Detection and monitoring of polluted sources e.g., industry, mining -Disaster e.g., forest fire, flooding, earthquake, tsunami, or tidal wave -Ecological/Environmental modelling -Emerging contaminants/hazardous wastes investigation and remediation -Environmental dynamics e.g., coastal erosion, sea level rise -Environmental assessment tools, policy and management e.g., GIS, remote sensing, Environmental -Management System (EMS) -Environmental pollution and other novel solutions to pollution -Remediation technology of contaminated environments -Transboundary pollution -Waste and wastewater treatments and disposal technology
