Simultaneous versus sequential settlement in territorial species

Article Abstract:

The hypothesis that simultaneous and sequential settlement patterns affect territory size and resident density of territorial animal species was studied in the lizard Anolis aeneus. Juveniles of the species were released either simultaneously or sequentially into microhabitat patches and were observed for settlement behavior. The results showed that about the same number of lizards settled when they were released simultaneously and when they were released sequentially, thus proving that behavioral factors affecting the settlement of habitats may be more complex than was previously assumed.

The effects of conspecific attraction and habitat quality on habitat selection in territorial birds (Troglodytes Aedon)

Article Abstract:

A study was conducted on the effects of habitat quality and conspecific attraction on the habitat selection among migratory house wrens. The data was collected from 1921 to 1939 on 6 hectare are that contained 58 nests at the Red River Valley, OH. Results indicate that both conspecifics and habitat quality determined habitat selection in naive male house wrens while experienced males picked high quality habitats without no evidence of conspecific inclinations. The results serve as the first empirical recording of conspecific preferentiality in habitat selection among territorial birds.

Sex-dependent habitat selection and genetic polymorphism

Article Abstract:

A study was conducted to evaluate the possibility that habitat selection affects genetic polymorphism in natural populations. The study assumes that no difference exists between male and female habitat selection and focuses on extant ecological sexual dimorphism on maintaining genetic variation through viability selection in various habitats. Results show that under some conditions, sex-dependent habitat selection improves genetic polymorphisms.
