ML: Live where? Does madagascar have seasonality?
|
-Madagascar
-High seasonality--> wet and dry seasons |
|
ML: How many eco-regions does Madagascar have?
What are the two different types of eco regions? What are the different eco-regions in each type? |
-Five eco regions
-The two types are dry and wet -3 dry eco-regions: deciduous forest, succulent woodland, spiny thicket -2 wet eco-regions: sub-humid forest, humid forest |
|
Adaptive radiation of Malagasy prosimians:
-How many genera? - How many living species? -How many sub-fossil genera? how big were they and how long ago did they go extinct? |
-14 genera
-43 living species -6 sub-fossil genera, giant lemurs about size of a gorilla, went extinct about 500 yrs ago(relatively recently) |
|
-What is the latin name for dwarf lemurs?
-How many genera? -What are the five genera? -Where on madagascar are they found? |
- Cheirogaleidae
-5 genera:microcebus,phaner, mirza, chirogaleus, allocebus -found in each eco-region--> diff. species for each region |
|
body size of the cheirogaleidae?
(2 things) how much does microcebus weigh? |
-smallest living primates
-body size 500 g -Microcebus: 30 g |
|
ML--> C:
Nocturnal or diurnal? |
nocturnal
|
|
DNA or field work on ml/c? (difficulty level)
|
cryptic diversity--> nocturnal hard to find/observe
|
|
ML/C diet?(2 things)
low quality or high quality? |
-Largely insectivores
-also frugivores -high quality diet b/c need sugars and proteins to keep small body running |
|
ML/C:
Adaptations for seasonality(3 things) |
-Hibernation
-Torpor -Eating of insect secretions |
|
ML/C:How long is hibernation? What physical adaptation do have for this?
|
(7 mo in Cheirogaleus)
•Tail full of fat to keep fed during hibernation |
|
ML/C:What is torpor?
when does it happen? what do they eat? |
-reduced activity--> don't do as much
-happens mostly during dry season -eat insect secretions |
|
ML/C:traditional view of them?
why? (3 reasons) |
-primitive --> do things that make them seem close to ancestral condition
-dispersed sociality,solitary foragers, sleep in nests |
|
ML/C: Microcebus How many species?
|
8 species
|
|
ML/C:Microcebus social organization? (5 things)
|
-female philopatry
-male dispersal -overlaping homeranges -solitary foraging -communal nesting |
|
ML/C:Def. Matrilocal females
|
-females tend to stay in natal area
|
|
ML/C:def. overlaping homeranges?
|
individuals' homeranges overlap
|
|
ML/C:"groups" in microcebus
|
-individuals with overlapping homeranges who communally nest together are considered groups
|
|
ML/C:3 grouping patterns
|
-multimale, unifemale
-multimale, multifemale -multifemale(bachelorette groups) |
|
ML/C:grouping pattern: multimale, multifemale: (3 things)
2 reasons: |
-provides opportunity for polyandry
-one female's homerange overlapped by several male homeranges -communally nests with males -reasons: 1) more males more protection from predators, 2) more individuals less likely predator get female |
|
ML/C:Multi female: (3 things)
|
-bachelorette groups
-male solitary: individual males have homeranges that overlap the female groups homerange -cooperative breeding: females help eachother rear offspring |
|
ML/C:Socioecological model: FEMALE PERSPECTIVE:
-what about resources? -predation rate? (low or high, percentage,what does this put pressure for?) - |
-unknown recource characteristics
-high predation: (50% predation rate)--> high pressure for communal nesting - |
