Abstract

Geographical and environmental factors influence the food availability and diet of orangutans. Moreover, tree phenology affects productivity and food availability in orangutan habitats. As a result, orangutans must be able to adapt to their food availability in the wild. This study aims to analyse the daily activity patterns and eating behaviour of the Sumatran orangutan (Pongo abelii) and their relationship to food availability through the fruit availability index (FAI) and phenology at Soraya Research Station (SRS), Aceh. From the 648 hours of observation on five orangutans' daily activities, we found that resting is the activity with the highest percentage (48%), followed by feeding (22.5%) and moving (21.8%). The high percentage of resting activity might correlate with its low FAI in SRS (1.01%). The resting activity limits orangutans' energy expenditure. Furthermore, barks, fruits, and other plants (including lianas, ferns, and epiphytes) were the main type of diet of Sumatran orangutans in SRS with a frequency of 40.6%, 28.9%, and 15.6%, respectively. The high bark consumption by the orangutans acts as their fallback diet at SRS and is thought to be a form of adaptation to the low fruit availability. This study showed the orangutan adaptation to low fruit availability in SRS through their daily activity and diet patterns.

Abstract

Understanding feral cat behavior can be one of the aspects that is necessary for proper management and taking policy action in controlling the cat population. This study aimed to observe the daily activities of feral cats and see the correlation between the number of visitors on cat-to-human interaction at a canteen in IPB University. Observation of cat’s daily behavior was conducted by scan sampling method and cats’ interaction with humans was conducted by ad libitum sampling. Our results showed that self-care (66.27%) dominated the daily behavior of cats followed by negative behavior (20.83%) and affiliative behavior (12.9%). Correlation test showed there was a significant negative correlation between the number of visitors and frequency of affiliative behavior (p = 0.024). The number of visitors also shows a positive correlation to self-care (p = 0.034). No significant correlation between the number of visitors and negative encounters behavior (p = 0.27). The highest frequency value of cat-human interaction was approaching human (A) 28.15%, followed by vocalization (MV) 28.15% and eye contact (KM) 22.71%. Cat-human interaction behavior did not significantly correlate with the number of visitors (p 0.05). Our result implies that the feral cat’s use the canteen as a place to rest, not a place to find food and daily activities and human-cat interactions were specific for each study site. Therefore, in the management of feral cats, it was necessary to pay attention to the conditions of their respective habitats.

Abstract

Correlations between natural geographic boundaries and variations in organisms' morphology have been well-documented in Sulawesi Island, which has a unique geological history and hundreds of endemic species. One of the widely distributed species of small mammals is Sulawesi giant rat (Paruromys dominator). Considering the geographic condition of Sulawesi, this species is a suitable model for studying geographic influences on morphological change. Moreover, there are no comprehensive studies on this species. Previous studies cannot fully explain the variability due to the lack of representative samples. Here, we measure 19 skull characteristics for 131 adult complete-skull specimens from six distribution areas in Sulawesi. We investigate the variation in skull characteristics using agglomeration nesting (AGNES) for cluster analysis and the standardized major axis (SMA) for allometry analysis. Our results show that P. dominator can be categorized into two groups, but distribution areas, elevation, or sex do not influence those. P. dominator in group 1 had a larger skull size than group 2. The two groups can be distinguished from four characteristics: breadth of mesopterygoid fossa (BMF), breadth of first upper molar (BM1), length of the auditory bulla (LB), and breadth of incisive foramina (BIF). The BMF and BM1 are related to mastication, and the LB and BIF are related to communication. We propose that the skull variation of this species is not correlated with geographical barriers but more clearly correlated with their feeding habits, mating behavior, and ability to escape predation. These findings were useful for future studies on the taxonomic status of P. dominator.

Abstract

Cockatoo (Cacatua sp.) is one of birds that is widely distributed in Indonesia and often kept as pet, thus threatening the Cacatua population in the wild. Environmental condition may affect the behavior of Cockatoo. Some unnatural behavior may arise due to living in the captive. Different cage conditions may result in different behavior performance in Cockatoo. Research on daily behavior at animal rescue sites at ASTI Bogor has never been conducted. This study aimed to analyze natural and stereotype behavior of Cacatua sp. at animal rescue center due to foreclosure, and analyze the relationship between cage condition and environmental factors. This study used focal instantaneous sampling, using eight individuals Cacatua sp. Cacatua sp. in ASTI performed natural behavior more than unnatural behavior, therefore ASTI can be a good place for animal rescue. The dominant natural behaviors were Resting (Re), Preening (Pr), Feeding (Fe), Locomotion (Lo), and Fighting (Fg), while unnatural behaviors were play, bite, abnormal vocalization, feather picking and aggressive. There are no difference in behavior between male and female, and also behavior in the morning and afternoon (p>0.05), but cage condition had a significant effect to daily behavior of Cacatua sp. (<0.05).

Abstract

The COVID-19 pandemic-related restrictions on physical activity outside can cause changes in physical activity in humans compared to before the pandemic. Differences in levels of physical activity are frequently associated with changes in stress levels, including in students. However, no longitudinal research has been conducted on the relationship between physical activity and stress levels in undergraduate students using the same respondents in different settings. This study aimed to assess the relationship between physical activity and stress levels in Indonesian students and to assess its consistency under different conditions. The data was collected from 81 undergraduate students in IPB University in two sampling phases: 2021 (during the Covid-19 pandemic) and 2023 (after the pandemic). The International Physical Activity Questionnaire (IPAQ) was used to assess the prevalence of physical activity, and the Perceived Stress Scale (PPS) was used to assess students’ perceived stress. The findings revealed that there were no differences in physical activity and stress levels between the two sampling phases. There was no significant relationship between physical activity and stress levels at either sampling time. These findings suggest that stress level at a certain level does not show any link to physical activity of the students.

Abstract

Anjing domestik (Canis lupus familiaris) dari famili Canidae merupakan salah satu spesies anjing yang telah melalui proses domestikasi. Masing-masing pemilik anjing akan memperlakukan hewan peliharaannya secara berbeda yang mengakibatkan perbedaan perilaku. Di antara lokasi-lokasi di kampus IPB Dramaga, lingkungan penangkaran Pusat Studi Satwa Primata menjadi salah satu tempat di mana anjing peliharaan banyak dijumpai. Metode focal animal sampling untuk mengamati perilaku anjing dengan interval waktu 10 menit dan data perilaku harian dibagi dalam 7 kategori yaitu ekskresi, lokomosi, perawatan diri, sosial, vokalisasi, inaktif dan negatif. Pada periode pengamatan dari pukul 09.00 hingga 13.00, tiga individu anjing menunjukkan perilaku istirahat dalam rentang 51-69% dan memilih lokasi yang dekat dengan pemilik untuk beraktivitas.

Abstract

Fluid intelligence is the ability to think logically and abstractly. Executive function is the behavioural ability to coordinate, control and adapt to new situations. Fluid intelligence and executive function play an important role in the ability to solve problems, adapt, and carry out daily behaviour. Previous research states that high fluid intelligence is followed by high executive function. Currently, there are no data regarding the relationship between fluid intelligence and executive function and the socio-demographic factors associated with both variables. Therefore, this study to examine the relationship and socio-demographic factors between fluid intelligence and executive function among university students in Indonesia. This study was conducted using a questionnaire and the zoom platform with a total of 306 university student in Indonesia. First, responders will complete a questionnaire containing demographic information. Second, respondents will be contacted again to assess fluid intelligence using the Baddeley Reasoning Test and executive function measurement using Tower of Hanoi. This study found that fluid intelligence was not substantially linked with planning time. However, high fluid intelligence was strongly related with less mobility and overall time. The socio-demographic component related with fluid intelligence is age. Sociodemographic factors related with executive function include sex, education level, and study discipline, as well as overall time.

Abstract

Self-assemblage is a form of social behavior observed in some earthworm species, where individuals spontaneously group with conspecifics. This behavior has been previously documented in Eisenia fetida, an epigeic species widely used in vermiculture. However, the presence of similar behavior in E. eugeniae, another commonly used vermicomposting species, remains untested. This study aimed to investigate the self-assemblage behavior of E. eugeniae through a Y-tube choice test, evaluating individual preferences for conspecific presence. The experiment was conducted under controlled laboratory conditions using 30 replicates for both main (with conspecifics) and control (without conspecifics) treatments. Results showed a significant preference for the conspecific group in the main test (χ² = 6.5, p = 0.01), while no directional bias was observed in the control. However, decision-making time did not differ significantly between treatments (p = 0.63). These findings indicate that E. eugeniae displays active self-assemblage behavior. Further research is needed to identify the mechanisms underlying this behavior and its implications for applied soil ecology.

Abstract

Coat color in mammals plays important adaptive roles, including camouflage, communication, and thermoregulation. Intraspecific variation in coat color is often associated with local environmental conditions. This study investigates coat color and hair color banding in the common spiny bandicoot (Echymipera kalubu), which exhibits ventral color polymorphism. We examined twenty individuals from Manokwari, West Papua, categorizing them into red-ventral and white-ventral groups. Coat color was quantified from digital photographs using CIE Lab* values, and hair color banding types were analyzed microscopically from body areas: dorsal, lateral, and ventral. Significant differences were found between the two groups and among the body areas. Red-ventral individuals exhibited higher a (redness) and b (yellowness) values, especially in the ventral area, whereas white-ventral individuals showed higher L (Lightness) values and reduced chromaticity. Seven hair color banding types were identified, with red-ventral individuals displaying a more diverse hair color banding type across body areas, particularly in lateral and ventral areas. Habitat substrate color analysis revealed that red-ventral individuals inhabited darker, red-yellow environments, whereas white-ventral individuals occupied lighter, less saturated habitats. The dorsal-to-ventral gradient in pigmentation and banding in E. kalubu is predicted to have a countershading function to avoid predators.
