Begin M, Roff D
J Evol Biol
. 2017 Dec;
14(1):1-13.
PMID: 29280575
An important issue in evolutionary biology is understanding the pattern of G matrix variation in natural populations. We estimated four G matrices based on the morphological traits of two cricket...

GENETIC CORRELATIONS AMONG TRAITS DETERMINING MIGRATORY TENDENCY IN THE SAND CRICKET, GRYLLUS FIRMUS
Fairbairn D, Roff D
Evolution
. 2017 Jun;
44(7):1787-1795.
PMID: 28567809
Migration by flight is an important component of the life cycles of most insects. The probability that a given insect will migrate by flight is influenced by many factors, most...

Evolution
. 2017 Jun;
47(5):1572-1584.
PMID: 28564895
Many organisms show distinct morphological types. We argue that the evolution of these alternate morphologies depends upon both fitness differences between morphs within each sex and the genetic correlation between...

Roff D, Wolak M, Correa L, Soto-Gamboa M
Heredity (Edinb)
. 2017 Apr;
119(3):136-141.
PMID: 28402328
In some mammals, female characteristics have been shown to depend, in part, on the intrauterine position during development of female fetuses relative to male fetuses. Females developing in close proximity...

Oecologia
. 2017 Mar;
19(3):217-237.
PMID: 28309236
A model is presented which demonstrates that a stable polymorphism for dispersal tendency can be generated under a wide range of conditions. These conditions include both different genetic models and...

Oecologia
. 2017 Mar;
15(3):259-275.
PMID: 28308551
In a previous paper (Roff, 1974) a simulation model was presented demonstrating the importance of dispersal in a spatially heterogeneous environment. In the present paper this model is analysed in...

Oecologia
. 2017 Mar;
15(3):245-258.
PMID: 28308550
The hypothesis that dispersal in a heterogeneous environment can be an important factor in population stability is examined. It is shown that dispersal may increase the persistence time of a...

Oecologia
. 2017 Mar;
12(1):35-54.
PMID: 28307723
Some statistical tests used in mark-recapture analysis are examined. It is shown that the tests presently available are insensitive and are not adequate under certain conditions. The most important of...

. 2017 Mar;

PMID: 28307722
The behaviour of the mark-recapture estimators of Petersen, Bailey (triple catch) and Jolly and Seber are examined theoretically and empirically by means of simulation techniques. The correlation between the parameter...
