(QUIZ 8) Flashcards
Sympatry concerns how species share the same habitat through niche partitioning
True
Comparative studies of sympatric primates offer insights on subtle distinctions in adaptations.
True
“Why” questions concerning how sympatric relationships developed are complicatied by the fact that the taxa of concern have taken particular niches over significant amounts of geologic time under changing environmental conditions.
True
At one time diurnal social behavior was viewed as better than nocturnal solitary living. Support for the traditional view comes from nocturnal primate increased vulnerability to predation (when compared to diurnal primates who have the protection of living in large social groups)
False
Match taxa by predation risk relative to diurnality and nocturnality.
Cheirogaleids, Lorisinae
Reduced risk of predation
Match taxa by predation risk relative to diurnality and nocturnality.
Lemurids, Colobinae
increased risk of predation
Match taxa by predation risk relative to diurnality and nocturnality.
Galagidae, Tarsiiformes
reduced risk of predation
Match taxa by predation risk relative to diurnality and nocturnality.
Cercopithecinae, Platyrrhini
increased risk of predation
Field research has demonstrated that small primates are more vulnerable to predation than are larger-bodied primates.
False
Pat Wright (Ciochon & Nisbett, 1998) compared the foraging behaviors of sympatric owl monkeys and titi monkeys and discovered that body size and social structure variation forced Aotus to fill the nocturnal niche.
False
As Pat Wright’s comparative data from distinct owl monkey localities demonstrates (Ciochon & Nisbett, 1998) – raptor activity patterns influence monkey behaviors in unexpected ways including activity patterns and degree of noisy foraging.
True
Based on Leland & Struhsaker’s research (Ciochon & Nisbett, 1998) we can see that groups with strong social heirarchies are more cohesive. This has resulted in advantages for male monkeys in the crested mangabey species.
False
Diurnal social groups have the benefits of large group living (more eyes and ears for predator warning alarms) but also are more vulnerable to predators who are attracted to these large clumped resources!
True
The kindness of sympatric strangers suggests that the red colobus monkeys at the study site had a social system that required the benefits of mixed-species associations for male and female teenagers. In fact, male red colobus monkeys were more dependent on the kindness of sympatric vervets and patas monkeys than were female red colobus monkeys
True
describe varying degrees of “teamwork” – the Black-&-White Guereza Colobus & Crested Mangabey lacked teamwork skills but the Red Colobus and Crowned Hawk-Eagle knew the value of teamwork
True
