Abstract. Ilham F, Ciptadi G, Susilorini TE, Putra WPB, Suyadi S. 2023. Morphology and morphometric diversity of three local goats in Gorontalo, Indonesia. Biodiversitas 24: 1366-1375. This research aimedto identify morphology and morphometric, as well as body indices and measurements markers, for use inlocal goats selection program in Gorontalo, Indonesia. The samples consisted of 37 Etawah Crossbreed, 96 Local Gorontalo, and 40 Kacang goats raised by traditional semi-intensive breeders. The morphological variables observed included feather color, color combination pattern, nose, ear shape, horn, beard, tail direction, and morphometric variables observed were withers height, hip height, hip width, body length, chest width, chest depth, chest girth, ear length, and ear width. The qualitative morphology was analyzed with descriptive method with Chi-squared test. While, the morphometrics of goat was used for calculating the body indices and principal component analysis.The results of the chi-square analysis showed significant differences in qualitative morphology among the three observed breeds (p<0.05), except for the presence of horns, beards, and the direction of the tail. The body measurements of Local Gorontalo goats were significantly different from those of Kacang goats except for chest depth. The only difference between the Etawah Crossbreed and the other two breeds included body weight,wither height, hip height, body length, ear length,and ear width (p<0.05). The three local goats had a long body length and legs, with a waist higher than the shoulders. Meanwhile,the medigline classification was only for Local Gorontalo and Kacang goats that had good thoracic development. The conformation index of the three local goat breeds had a significant correlation with body weight. The variables with the best contribution from the first component that can be considered sequentially in the selection program for Etawah Crossbreed goats, Local Gorontalo, and Kacang goats were body length, chest girth, and wither high. For the second component, the variables included ear length and chest width, while that of the third component in Kacang goats wasear length.

Abstract. Tuska HSA, Hariati AM, Sanusi A, Ciptadi G, Rumhayati B, Susanto H, Residiwati G, Aulanni’am A. 2025. Reproductive toxicity and histopathological effects of heavy metal exposure in male Nile tilapia from the Brantas River, Indonesia. Biodiversitas 26: 5169-5180. Heavy metal pollution in freshwater ecosystems poses critical threats to fish health, particularly reproductive function. The Brantas River, one of Indonesia’s most economically important watersheds, has experienced escalating contamination due to industrial, agricultural, and domestic waste discharges, leading to ecological concern. This study aimed to evaluate the bioaccumulation and toxicological effects of heavy metals on histopathological alterations (necrosis, inflammation, hyperemia, and hyperplasia) in gills and testes, and on sperm quality (viability, DNA integrity, and morphological abnormalities) of male Nile tilapia (Oreochromis niloticus) from the Brantas River Basin, Malang, East Java, Indonesia. Water and tissue samples were collected from five river sites (25 male fish; 5 fish per site). Heavy metal levels in water were analyzed using Atomic Absorption Spectrophotometry (AAS). Histopathological scores were evaluated semi-quantitatively. Sperm viability, DNA fragmentation, and morphology were assessed microscopically. Statistical analyses included One-Way ANOVA and Spearman correlation tests (IBM SPSS 23.0; p<0.05). Cadmium (Cd) and iron (Fe) were found at elevated concentrations, particularly at Kalisari (Cd = 0.0129 ppm; Fe = 7.690 ppm]), exceeding WHO (0.003 and 0.3 ppm) and USEPA (0.005 and 0.3 ppm) guidelines. Fish from this site exhibited the most severe histopathological alterations in both gills and testes: necrosis (1.8±0.24; 2.27±0.70), inflammation (2.13±0.27; 2.00±0.85), hyperemia (1.93±0.27; 2.60±0.63), and hyperplasia (2.07±0.27; 2.33±0.72), respectively. Sperm quality was significantly compromised: viability (60.27±1.17%), DNA fragmentation (59.4±0.87%), and morphological abnormalities (43±1.47%) (p<0.05). Strong positive correlations were found between Fe levels and testicular inflammation (r?=?0.909), testicular hyperplasia (r?=?0.921), and gill hyperplasia (r?=?0.913) (p<0.05). Cd was negatively correlated with sperm plasma membrane integrity (r?=?-0.927) and DNA integrity (r?=?-0.896) (p<0.05). In conclusion, chronic exposure to Cd and Fe in the Brantas River is associated with marked tissue pathology and reduced reproductive performance in Nile tilapia. These findings underscore the urgent need for integrated river health monitoring and pollution control strategies to protect aquatic biodiversity and sustain ecosystem services in the Brantas River Basin.
