Age-specific differences in Asian Elephant defecation, dung decay, detection and their implication for dung count
<p><span>In vertebrate population estimation, converting faecal density into animal density requires information on faecal production rate, decay rate, and faecal density. Differences in the above factors for long-lived species across age classes were not evaluated. We have evaluated these factors associated with the dung count of Asian elephants </span><span>(<em>Elephas maximus</em>) </span><span>in the tropical forest of Southern India. </span></p> <p><span>The defecation rate of elephants was determined in semi-wild elephants at the Mudumalai elephant camp. The relationship between dung bolus diameter and age was determined to estimate the age of the elephant. Total and age-specific elephant density based on dung bolus diameter were estimated. A total of 24 transect lines of 2-4 km (125 km) were sampled in the study area. An experiment was conducted to assess detection probability across the age classes of dung piles. The dung decay rates across age classes and seasons were determined by marking fresh dung piles (n=1551). The dung-based age structure assessment and its limitations were evaluated. </span></p> <p><span>The mean defecation rate was 13.51</span><span>±</span><span>0.51 per day. The defecation rate was significantly lower for the younger age class and increased with the age of elephants. Defecation rates were significantly lower in the wet season than in the dry. </span><span>The dung-boli diameter positively increased with the age of elephants, and the growth curve can be used to predict the age and age structure of the elephant population. </span></p> <p><span>The disparity in the dung production rate results in the lower availability of younger age class (Juvenile and calf) dung in the transect for counting, that results in lower dung abundance. The detection probability of dung piles of younger age classes was low (0.58). The survival rates of dung piles of younger age classes were lower and increased with the age of elephants in the wet season. </span><span>Hence, demography assessment of the population based on dung needs to consider age-specific differences in dung production, decay, and detection probability. Through demography assessment using dung provides insight into population age structure, it has limitations </span><span>in predicting age structure for young elephants. </span></p>

Data from: From inside to outside and back again: changing waste dump formation, defecation and worker localization in a clonal ant
Reproductive division of labor is a defining feature of all eusocial organisms. In the eusocial insects, non-reproductive labor is often also divided into safe tasks within the nest, such as nursing, and risky extranidal tasks, such as scouting and foraging. Within-nest (intranidal) tasks are usually performed by younger workers while older workers forage outside. This temporal specialization can be delayed, accelerated or even reversed if the need arises. Here, we studied reversion in the clonal ant Platythyrea punctata. Rather than focusing on traditional markers of temporal polyethism, such as nursing vs. foraging, we examined neglected behaviors, such as waste management and defecation, as well as the proportion of ants outside the nest and the onset of egg laying. We formed single-age groups of young intranidal, old intranidal and forager workers, and found strong differences in behavior between these groups. Intranidal workers rapidly created well-formed waste dumps (middens) and defecated within the nest, initiated egg laying sooner, and remained mostly inside the nest. Forager workers showed the reverse pattern. However, the behavior of the groups gradually converged, and after 8 weeks midden formation was similar and the proportion of ants outside the nest was identical across all groups. This study demonstrates reversible temporal polyethism in defecation and waste management, which correlates well with more traditionally studied age-related traits. Different traits seem to revert at different rates. Waste management behavior may provide an easy and low-impact way of examining behavioral reversions and allows insights into aspects of colony life not usually examined.
