Ecological phylogenetics
Ecological phylogenetics is the
study of ecological traits and adaptations in a phylogenetic perspective. This
approach has been explored in several connections:
A
reexamination has been made of the interpretation of orb-weaver sexual size
differences from a phylogenetic perspective* and is being followed by a general
analysis of spider sexual dimorphism (N. Scharff, with J.Coddington,
Smithsonian Institution, Washington, and G. Hormiga, George Washington
University, Washington, D.C.).
Papers
have been written on the evolution of flightlessness and wing polymorphism in
insects in general* and in water striders (Hemiptera: Gerridae) in particular*.
The evolution of mating systems and sexual dimorphism in water striders have
been analyzed and discussed in three papers*. The methods of using cladistic
inference in describing evolutionary scenarios have been exemplified by a paper
on locomotory structure, function and performance in semiaquatic bugs*
(Hemiptera: Gerromorpha) (N.M. Andersen). A review on interactions between
systematics and ecology as exemplified by water striders has been published*
and the preparation of a book-size publication on the systematics, evolution,
ecology and behaviours of semiaquatic bugs has been resumed (N.M. Andersen,
with J.R. Spence, University of Alberta, Edmonton).
A
review of the evolution of life-history traits, habitat preferences, feedings
habits etc. of staphyliniform beetles has been completed*, as an extension of a
phylogenetic analysis of the group (M. Hansen).
An
account of the ecological scenario of basal amphiesmenopteran evolution in the
light of recently acquired phylogenetic insights has been completed* (N.P.
Kristensen).
