Abstract

Graphical Abstract Highlight Research 1. Tor tambra is the most dominant species other Tor species in Aceh Province, Indonesia. 2. The population of T. tambra has decreased significantly due to overfishing and environmental destruction. 3. This research aims to examine the habitat characteristics, growth patterns and condition factors of T. tambra. 4. Analysis of the length weight relationship of T. tambra revealed that the condition of the fish was stable . Abstract This research was aimed to examine the habitat characteristics, growth patterns and condition factors of T. tambra in the Mamis River, Leuser Ecosystem Area, Aceh, Indonesia. This research was conducted on the Mamis River in three different river conditions from July to August 2023. The ecological parameters of T. tambra were conducted by observing the main, broodstock, spawning, and nursery ground habitats based on diversity of catch size at a location, water quality, aquatic substrate, aquatic vegetation, and water shade. The growth pattern parameter was also analyzed to reveal the condition of T. tambra.  The T. tambra habitat in the Mamis River includes broodstock and spawning habitat with the criteria from small to large rocks overgrown with Bryophytes, gravel and sand substrates, clear water color, slow to swift water currents, and river environment most of it is primary forest. In the main habitat, there is dominant riparian vegetation in the form of forest timber trees such as Pometia pinnata, Ficus fistulosa, Hydnocarpus castanea, and Aglaia tomentosa. The habitat for the juvenile is in the form of rocks, gravel substrate, clear water color, and fast water currents. In the nursery habitat, the dominant riparian vegetation is Balakata baccata. Based on the results of water quality analysis at the three stations, it shows that temperature, pH, DO, currents, BOD, COD are significantly different, but brightness levels are not significantly different. Based on the analysis of the length-weight relationship, it shows that the condition of the fish is stable with sufficient food availability.

Abstract

Wing morphometry plays a crucial role in avian functional ecology, influencing flight performance, energy efficiency, and sexual selection. However, quantitative data on wing development in lovebirds (Agapornis fischeri), remain scarce. This study aimed to quantify and compare the growth of wing flexion width, wing extension width, and wingspan in male and female lovebirds at 4, 5, and 6 months of age to determine the onset and extent of sexual dimorphism. A total of 22 lovebirds (11 males and 11 females) were acclimatized under controlled environmental conditions and fed a millet-based diet. Wing measurements were obtained in accordance with animal welfare protocols using standardized morphometric techniques. Data were analyzed using Multivariate Analysis of Variance (MANOVA) followed by Tukey’s post hoc test at a 95% confidence level, and growth patterns were evaluated using linear regression analysis. Results showed significant (p < 0.05) sex- and age-related differences in all morphometric parameters. Males exhibited consistently higher mean values for wing flexion, extension, and wingspan at every age, with steeper linear growth slopes compared with females. The steady, positive correlation between age and wing dimensions indicates continuous and proportional development during the juvenile phase. These findings suggest that sexual dimorphism in wing morphology becomes evident as early as four months of age and intensifies with maturation. This study provides baseline trajectories of wing morphometrics in lovebirds, establishing reference standards that are valuable for avian biology, welfare, and sexing applications in psittacine species.

Abstract

This study presents a comprehensive gross anatomical and histological characterization of the alimentary tract in the fruit bat (Rousettus amplexicaudatus), a frugivorous megachiropteran species whose digestive morphology remains incompletely described. Seven adult bats (four males, three females) were captured in Banyuwangi, East Java, and examined through standardized morphometric, gross anatomical, and histometric analyses. Euthanasia was performed using Xylazine and Ketamine, followed by systematic dissection and measurement of body and visceral parameters. Histological preparations of the esophagus, stomach, duodenum, jejunum, ileum, and colon were stained with hematoxylin and eosin and evaluated microscopically. Results revealed minimal sexual dimorphism in external and internal morphometric traits, except for a significantly longer esophagus in males (p < 0.05). Gross anatomy showed a simple, glandular stomach and an elongated intestinal tract, consistent with adaptations for rapid carbohydrate digestion. Histomorphometric evaluation indicated comparable mucosal and muscular thickness between sexes, suggesting functional uniformity in digestive performance. Histological observations identified a stratified squamous esophageal lining, glandular gastric mucosa, prominent intestinal villi with crypts of Lieberkühn, and well-developed Peyer’s patches, highlighting efficient nutrient absorption and mucosal immune function. Overall, the findings demonstrate that fruit bat possesses a structurally specialized yet sexually consistent digestive system optimized for frugivory. This integrative dataset fills critical gaps in bat digestive morphology, providing a standardized anatomical and histological reference for comparative physiology, dietary adaptation, and host–pathogen interaction studies in megachiropteran bats.
