Animals in Animal-Assisted Services: Are They Volunteers or Professionals?
With the increasingly common practice of Animal-Assisted Services (AAS), whether in therapy, coaching, education, or volunteering programs, the concern over animal welfare has also risen. However, no…

The ecological benefits of interceptive eavesdropping
- Environmental Science
Scimitarbills underwent significant behavioural changes in the presence of social pied babblers: they reduced their vigilance rate by over 60%, increased their foraging efficiency and expanded their niche by moving into open habitat and excavating subterranean food items.
Heterospecific eavesdropping in a nonsocial species
Predation risk alone may be sufficient to drive the evolution of heterospecific eavesdropping in Gunther's dik-dik, a monogamous, territorial, and nonsocial miniature antelope with a simple vocal repertoire.
A micro-geography of fear: learning to eavesdrop on alarm calls of neighbouring heterospecifics
- Environmental ScienceProceedings of the Royal Society B: Biological Sciences
It was found that superb fairy-wrens fled to cover to playback of noisy miner (Manorina melanocephala) aerial predator alarm calls only in locations where miners were present, suggesting that learning rather than acoustic structure determines response.
Eavesdropping on heterospecific alarm calls: from mechanisms to consequences
- Computer ScienceBiological reviews of the Cambridge Philosophical Society
Overall, it is known that eavesdropping on heterospecific alarm calls is an important source of information for many species across the globe, and there are ample opportunities for research on mechanisms, fitness consequences and implications for community function and signalling evolution.
MUTUALISM OR PARASITISM? USING A PHYLOGENETIC APPROACH TO CHARACTERIZE THE OXPECKER‐UNGULATE RELATIONSHIP
- Environmental Science, BiologyEvolution; international journal of organic evolution
It is found that both species of oxpeckers prefer ungulate hosts that harbor a higher abundance of ticks, and no evidence that hide thickness—a measure of the potential for parasitism by oxpecking—predicts oxpecker preferences for different ungulates species.
Birds Learn Socially to Recognize Heterospecific Alarm Calls by Acoustic Association

Red-billed oxpeckers: vampires or tickbirds?
Excluding oxpeckers from cattle as part of a controlled field experiment in Zimbabwe suggested that the oxpecker– mammal relationship is more complex than was previously thought.
The presence of an avian co-forager reduces vigilance in a cooperative mammal
- Environmental ScienceBiology Letters
This is the first study to demonstrate experimentally that a mammal reduces vigilance in the presence of an avian co-forager, and it is shown that dwarf mongooses significantly reduce their rate of vigilance when foraging with this species.
Interspecific Semantic Alarm Call Recognition in the Solitary Sahamalaza Sportive Lemur, Lepilemur sahamalazensis
- Environmental SciencePloS one
The results indicate that the Sahamalaza sportive lemur is capable of using information on predator presence as well as predator type of different sympatric species, using their referential signals to detect predators early, and that the lemurs’ reactions are based on experience and learning.
Pleistocene extinctions: the pivotal role of megaherbivores
- Environmental Science, GeographyPaleobiology
The elimination of megaherbivore influence is the major factor differentiating habitat changes at the end of the terminal Pleistocene glaciation from those occurring at previous glacial-interglacial transitions.
