Calliandra calothyrsus Meissn. leaf extract is potential as phytoestrogens. It influenced male mice reproduction, rat estrous cycle, and ovarian histology in previous study. This research aimed to prove the C. calothyrsus leaf extract potential as phytoestrogen source and the effect on endometrial thickness where the embryo implantation take place in early pregnancy. This study used a Completely Randomized Design used 54 days old female rats (Rattus norvegicus). Rats were divided into K as control group (treated with 0.5% Na-CMC as placebo) and P1, P2, and P3 as three groups with C. calothyrsus leaf extract administration with doses of 17.5; 35; and 70 mg/ kg bw respectively. Treatments were given 1 ml/rat/day orally for 20 days. At day 21st, animals were euthanized to collect blood samples for estrogen hormone analysis. After the dissection, all uterus were collected and weighed. Histological preparation was done with paraffin method and Hematoxylin-Eosin staining. The effective dose was 70 mg/ kg bw that did not decrease the weight of the uterus and the body. This dose even maintained the normal diameter and thickness of uterine walls (endometrium, myometrium, and perimetrium layers) like control rats. The extract in this study could increase estrogen concentration in female rats. This research novelty is that C. calothyrsus leaf extract (70 mg/ kg bw) can be used as an alternative herbal suplement to maintain uterine wall thickness and estrogen concentration in productive women. With further clinical research, this extract is a good candidate as potential estrogen source to overcome women infertility or pregnancy difficulties due to problem of endometrial thickness and lack of endogenous estrogen.

Southern Bluefin Tuna in spawning area of the Eastern Indian Ocean where the Indonesian’s longliners operated has a specific character in term of size, age, sex-specific growth rate and the population. The aims of this study are to determined changes in size/age, sex-specific growth rate and virtual population analysis of Southern Bluefin Tuna (SBT) in the spawning area. This study is important to find out the successful management of SBT in spawning area by looking at the catch at age/size movement, sex-specific growth analysis and the estimation of the population by virtual population analysis. In this study, we were used 452 pairs of otolith with fish sized from 134-196 cmFL and fish aged from 8-20 years. The growth equation was Lt = 191 (1-e-0,167(t+1,081)). Catch at age structure was distributed from 5-22 years with mean and mode of age were 9.63 and 9 years. The distribution of mode changed from year to year shifting to a younger fish. In 2012, the mode was 10 years but entering 2013-2014 the mode was shifted to 6 years. In 2015-2017, the mode was increased from 7 years (2015) to 8 years (2016) and 9 years (2017). The fishing pressure happened in the age group under 20 years. In 2012 to 2014, the highest fishing pressure respectively obtained in the age group of 13 to 11 years with an average length of 167 to 174 cmFL. Entering 2015 and 2016, the highest fishing pressure obtained in the age group of 6 years with an average length of 138 cmFL. The exploitation rate ranged from 0.14/year to 0.25/year meaning that the exploitation was in optimal condition.

The main purpose of the establishment Bali Barat National Park was to conserve the endemic endangered Bali Starling. However, based on data on 2004, one endangered species, Java Sparrow Lonchura oryzivora also resided in there. Current official report of sighting is ultimately required since it acts as reference in the management of a conservation area. We reported four sightings of Java Sparrow flocks occurred in June, 2021 at the Prapat Agung Peninsula, 28 individuals in total consisted of 13 adults and 15 juveniles, in a transition area of monsoon forest and savannah. The biggest flock sighted was eleven individuals. This study therefore confirmed that the Java Sparrow was still persisted at the Bali Barat National Park in 2021, in Prapat Agung Peninsula in particular.

Coral transplantation activities are carried out as conservation efforts to save coral reef ecosystems and the species that live and depend on these ecosystems. In its implementation, knowledge regarding effective and efficient transplantation methods is required. The aim of this research was to determine the effect of fragment size and water depth on the growth rate of transplanted Stylophora pistillata at Serangan Beach. By knowing this, coral transplantation activities can be carried out effectively. Field research was carried out from November to April 2022 using the Randomized Block Design method with two factors, namely depth variation (1 m, 3 m, and 5 m) and initial fragment sizes (3 cm, 5 cm and 7 cm). This study used 135 fragments of Stylophora pistillata. The analysis showed that the fragment sizes of 3 cm, 5 cm and 7 cm had significant differences in the rate of coral growth. However, based on the depth variation, only the depth of 1 m differed significantly from the other two depths. The best coral growth rate was observed in corals using an initial fragment size of 7 cm which was transplanted at a depth of 1 m with the highest average growth rates of 0.93 cm/month (height) and 0.79 cm/month (width). Based on the results, it was also known that the number of corals remaining at the end of the study was 265 fragments so the value of survival rate from transplantation activities was 97.78%. Maintaining environmental water conditions and carrying out maintenance and cleaning corals from algae and sedimentation needs to be carried out intensively to maintain the survival rate on Serangan Beach.

Birds are an important component of balancing ecosystems and have a reciprocal relationship and close dependence to their environment. The high number of bird species found can indicate the ecological role of the environment, either for finding food and shelter, or for nesting and breeding areas. Udayana University Bukit Jimbaran Campus, with a total land area of ??27,649 ha, still has plenty of green area. This condition provides great potential as habitat for various bird species. This study aims to identify the bird species found in Udayana University Bukit Jimbaran campus area. The method used was the point count method at 11 observation points that was determined by purposive sampling. The indices calculated were the diversity, uniformity, dominance, and relative abundance. From this study, 30 bird species from 18 families were recorded with a total of 571 individuals scattered at each observation point. Based on the calculated indices, the diversity of bird species in Bukit Jimbaran Udayana University campus area was considered as moderate, with a stable species distribution, and low dominance (no species dominates). Keywords: abundance, birds, diversity, dominance, evenness

Species introduction is a key conservation strategy for the Bali myna (Leucopsar rothschildi), a high-priority species in Indonesia. Successful introduction requires thorough habitat assessment. This study analyzed vegetation structure and identified potential key species in Tengkudak Village, Tabanan Regency, Bali–one of the designated introduction sites. A plot-based sampling method was used in 10 sampling areas, with 20 plots (20 m × 20 m) for tree and sapling analysis and 100 plots (2 m × 2 m) for ground vegetation assessment. Vegetation parameters such as density, frequency, dominance, and importance value index were analyzed, along with community indices, including Shannon-Wiener diversity, Simpson’s dominance, and Pielou’s evenness. The upperstorey was dominated by plantation species and riparian vegetation, while the understorey consisted mainly of agricultural weeds, grasses, and ferns. The community index analysis indicated high species diversity and a stable community structure. Most plant species provide essential resources for the Bali myna, including food, shelter, perching, and nesting sites. Fifteen species were identified as potential plant keys, including Baccaurea racemosa, Bischofia javanica, Carica papaya, Cocos nucifera, Dysoxyllum densiflorum, Elaeocarpus sphaericus, Ficus spp., Lansium domesticum, Magnolia champaca, Persea americana, Sandoricum koetjape, and Theobroma cacao.
