Spectrum of sociality - arthropods Flashcards
An exceptional diversity of social structures are seen across organisms. Common themes do exist, especially with respect to patterns of ________________________________.
offspring production and rearing
what are major categories of arthropod sociality based on?
- level of offspring care
- level of reproductive division of labor
- presence of overlapping generations
defining major categories - level of offspring care
do society members care for offspring that are not their own?
defining major categories - level of reproductive division of labor
do some society members specialize in offspring production to a greater extent than others?
defining major categories - presence of overlapping generations
do older individuals stay with or persist in the society to cooperate with subsequent generations of offspring?
The major categories of sociality in arthropods from least to most complex
- solitary
- subsocial
- communal
- quasisocial
- semisocial
- eusocial
define solitary
Showing no offspring care, reproductive division of labor, or overlap of generations
define subsocial
Adults care for their own offspring for some period of time — simple parental care
define communal
members of the same generation share a composite or group shelter, but without cooperating in offspring care.
define quasisocial
members of the same generation share a composite or group shelter and cooperate in offspring care
define semisocial
members of the same generation share a group shelter, cooperate in offspring care, and show reproductive division of labor.
define eusocial
shared group shelter, cooperative offspring care, division of labor, and overlap of generations
The ______________ of insects provide __________________________ to their offspring
- majority
- no parental care
____________ species provide _____________________ to their offspring past the egg laying stage
- Subsocial
- some level of care
how can subsocial species parental care vary?
- type
- duration
- parental involvement
what is an example of a subsocial species
a burying beetle
burying beetle - Mating pair forms over ________________, which is the resource for raising offspring
discovery of carrion
burying beetle - The cooperating female-male pair __________________________________.
bury carrion, mate, female lays eggs
burying beetle - ______________ to protect and tend to their larvae.
Both parents stay
burying beetle - At maturity, _______________________________ from the burrow
larvae pupate and parents disperse
