The value of age is well recognized in human societies, where older individuals often emerge as leaders tasks requiring specialized knowledge, but what part do such play other social species? Despite growing interest how effective leadership might be achieved animal systems, the specific role that may decision-making has rarely been experimentally investigated. Here, we use a novel playback paradigm to demonstrate African elephants (Loxodonta africana), affects ability matriarchs make...
Abstract 1. The physical and behavioral characteristics the temporal patterning of musth were studied over a ten-year period in free-ranging population African elephants. 2. Males spent more time association with females during than non-musth periods. 3. aggressive their periods non-musth. 4. occurrence duration age-related: no male under 24 years was seen musth; bouts must among younger individuals short sporadic, while older males experienced longer predictable on an annual basis. 5....
Lose the tusks Harvest and poaching of wildlife have increased as human population our technology grown. These pressures now occur on such a scale that they can be considered selective drivers. Campbell-Staton et al . show this phenomenon has occurred in African elephants, which are poached for their ivory, during 20-year Mozambican civil war (see Perspective by Darimont Pelletier). In response to heavy armed forces, elephant populations Gorongosa National Park declined 90%. As recovered...
Monitoring the location of conspecifics may be important to social mammals. Here, we use an expectancy-violation paradigm test ability African elephants ( Loxodonta africana ) keep track their companions from olfactory cues. We presented with samples earth mixed urine female that were either kin or unrelated them, and unexpected highly predictable at location. From behavioural measurements elephants' reactions, show can recognize up 17 females possibly 30 family members cues present in...
Abstract The costs of inbreeding depression, as well the opportunity avoidance, determine whether and which mechanisms avoidance evolve. In African elephants, sex‐biased dispersal does not lead to complete separation male female relatives, so individuals may experience selection recognize kin avoid inbreeding. However, because estrous females are rare male–male competition for mates is intense, be high, particularly males. Here we combine 28 years behavioural demographic data on wild...
Multi-level fission-fusion societies, characteristic of a number large brained mammal species including some primates, cetaceans and elephants, are among the most complex cognitively demanding animal social systems. Many free-ranging populations these highly mammals already face severe human disturbance, which is set to accelerate with projected anthropogenic environmental change. Despite this, our understanding how such disruption affects core aspects functioning still very limited. We now...
Abstract Nonrandom patterns of mating and dispersal create fine‐scale genetic structure in natural populations — especially social mammals with important evolutionary conservation consequences. Such is well‐characterized for typical mammalian societies; that is, societies where group composition stable, male‐biased, males form permanent breeding associations just one or a few groups over the course their lives. However, not well understood differ from this pattern, including elephants. In...
Growth from conception to reproductive onset in African elephants (Loxodonta africana) provides insights into phenotypic plasticity, individual adaptive plastic responses and facultative maternal investment. Using growth for 867 life histories 2652 over 40 years, we demonstrate that inexperience plus drought early result reduced rates sons higher mortality both sexes. Slow during lactation was associated with smaller adult size, later age at first reproduction, lifetime survival consequently...
Abstract As the human footprint expands worldwide, people and wildlife are coming into greater contact, areas of activity may be simultaneously associated with risk reward for animals. To avoid threats while exploiting opportunities, animals adjust their spatiotemporal activity, using anthropogenic disturbance at night when less active. We combined four camera trap datasets from Mozambique's Gorongosa National Park to evaluate effects roads settlement on diel patterns elephants ( Loxodonta...
The ability to discriminate between call types and callers as well more subtle information about the importance of a has been documented in range species. This type discrimination is also important vibrotactile environment for species that communicate via vibrations. It recently shown African elephants (Loxodonta africana) can detect seismic cues, but it not known whether they from noise. In series experiments, familiar unfamiliar alarm calls were transmitted seismically wild elephant family...
