Renewed interest in fission‐fusion dynamics is due to the recognition that such may create unique challenges for social interaction and distinctive selective pressures acting on underlying communicative cognitive abilities. New frameworks integrating current knowledge emerge from a fundamental rethinking of term “fission‐fusion” away its general use as label particular modal type system (i.e., “fission‐fusion societies”). Specifically, because degree spatial temporal cohesion group members...
The process of weaning is related to a critical or threshold body weight attained by offspring among large‐bodied mammals; the anthropoid primates, ungulates and pinnipeds. While was allometrically maternal in interspecific comparisons, it isometrically neonatal weight. When neonate had grown four times its birth weight, weaned. Differences between taxonomic groups were found only fasting phocids, where weanlings lower, but proportional, duration lactation weakly varied individuals...
Wild capuchin monkeys inhabiting dry forest were found to customarily use tools as part of their extractive foraging techniques. Tools consisted twigs and sticks, often modified, which used probe for insects and, most frequently, stones a variety sizes shapes cracking digging. The digging has been thought be restricted humans. These monkeys, living in harsh habitat, survive food limitation time constraints through extensive tool use.
In recent years there has been a proliferation of projects aiming to integrate human development needs with conservation objectives, and establish mutually beneficial relationships for the management natural resources between rural communities state. This paper presents data from case study human-wildlife interactions in villages along northern boundary Selous Game Reserve south-east Tanzania. Since 1989, this area site project working promote community wildlife (CWM). Questionnaire survey...
The ability of newborns to digest proteins, fats, and carbohydrates depends, a large extent, on their level exocrine pancreatic function. Building the limited published data, we studied enzyme activities in duodenal fluid response pancreas secretogogues 15 premature full-term infants at birth 30 days age. We compared these findings those obtained from identical studies 17 children age 2 years above. In addition, measured exopeptidase, carboxypeptidase B, relation other enzymes. contained no...
Hominid evolution is marked by very significant increase in relative brain size. Because size has been linked to energetic requirements it possible look at the pattern of encephalization as a factor human foraging and dietary strategies. Major expansion associated with Homo rather than Hominidae whole, costs are likely have forced prolongation growth rates secondary altriciality. It calculated here that modern infants approximately 9% greater similar apes due their large brains....
Abstract Land outside of gazetted protected areas is increasingly seen as important to the future elephant persistence in Africa. However, other than inferential studies on crop raiding, very little understood about how elephants Loxodonta africana use and are affected by human‐occupied landscapes. This largely a result restrictions technology, which made detailed assessments movement challenging. Recent advances radio telemetry have changed this, enabling researchers establish over 24‐h...
While the energetics of reproduction have been intensively investigated among women, studies mother‐offspring relationships non‐human primates tended to neglect effect nutrition mother on lactational performance and growth survival offspring. Typically fertility has compared between populations under different nutritional regimes. In this paper, relations suckling frequencies, time weaning, survivorship offspring, contraceptive effects lactation quality maternal diets are outlined. Energy...
We analyzed data from over 4500 elephants to show that animals in European zoos have about half the median life span of conspecifics protected populations range countries. This discrepancy is clearest Asian elephants; unlike African zoos, this species' infant mortality very high (for example, twice seen Burmese timber camps), and its adult survivorship has not improved significantly recent years. One risk factor for zoo being moved between institutions, with early removal mother tending...
Long-lived species such as elephants, whales and primates exhibit extended post-fertile survival compared to with shorter lifespans but data on age-related fecundity are limited few or populations. We assess relationships between longevity, reproductive onset, rate age for 834 longitudinally monitored wild female African elephants in Amboseli, Kenya. The mean known at first reproduction was 13.8 years; only 5 % commenced by 10 years. Early reproducers (<12.5 years) had higher age-specific...
Abstract We present body mass (N = 419) and crown‐rump length (CRL, N 210) measurements from 38 male 49 female mandrills born into a semifree‐ranging colony in order to describe growth birth adulthood, investigate maternal influences upon growth. Adult are 3.4 times the mass, 1.3 CRL, of adult females. Body dimorphism arises combination sex differences period (females attain at 7 years, males 10 years) rate. Both sexes undergo subadult spurt this is much more dramatic (peak velocity 551...
Abstract Predation pressure has long been proposed as a determinant of mammalian social systems. Group size and composition were compared for 121 populations cercopithecoid primates, from 39 species 13 genera, living under low, moderate or high predation risk. In confirmation previous studies, risk was found to have major effect on group size, with in significantly larger groups than those at lower However, there differences structure between the categories. Unimale smaller, had fewer...
This paper presents an analysis of perceived patterns wildlife crop-damage in relation to on-farm assessment damage area bordering the Selous Game Reserve (SGR) south-eastern Tanzania. Data from attitudinal questionnaire survey 202 households four villages are used examine local perceptions terms relative impact and which species were responsible. We explore influence on attitudes adjacent game reserve. frequency events estimated severity impacts, recorded during a 6-month programme...
Digestive enzymes in faeces have been reported to posses skin irritation potential. The present study was designed investigate the vivo irritant potentials of faecal concentrations proteolytic and lipolytic digestive bile salt mixtures. In a 21‐day cumulative assay, clinical evaluation noninvasive bioengineering techniques were used. 5 days occlusive exposure phosphate buffer (pH = 8) caused no visual damage but reflectance spectroscopy demonstrated significant vasodilation ( p < 0.01)...
