Conceptual issues in local adaptation
TLDR
This paper advocates multifaceted approaches to the study of local adaptation, and stresses the need for experiments explicitly addressing hypotheses about the role of particular ecological and genetic factors that promote or hinder local adaptation.
Adaptation to Marginal Habitats
The ability to adapt to marginal habitats, in which survival and reproduction are initially poor, plays a crucial role in the evolution of ecological niches and species ranges. Adaptation to marginal
Evolutionary biology of starvation resistance: what we have learned from Drosophila
TLDR
DrosophILA offers a unique opportunity for an integrated study of the manifold aspects of adaptation to nutritional stress, and the insights from Drosophila are likely to apply more generally than just to dipterans or insects.
A fitness cost of learning ability in Drosophila melanogaster

TLDR
It is shown that the evolution of an improved learning ability in replicated experimental fly populations has been consistently associated with a decline of larval competitive ability, compared with replicated control populations, providing evidence for a constitutive fitness cost of learning ability.
Natural polymorphism affecting learning and memory in Drosophila
TLDR
It is shown that forR-like levels of both short-term learning and long-term memory can be induced in fors flies by selectively increasing the level of PKG in the mushroom bodies, which are centers of olfactory learning in the fly brain.
The differential genetic and environmental canalization of fitness components in Drosophila melanogaster
TLDR
Measurements of environmental canalization for Drosophila melanogaster suggest that developmental mechanisms buffer the phenotype against both genetic and environmental disturbance, and suggest, less strongly, that inbreeding weakens canalization.
Evolutionary Consequences of Asymmetric Dispersal Rates
TLDR
The model predicts that the population will be most likely to adapt to that habitat if the dispersal rates in both directions are high, highlighting the general message that the effect of gene flow upon local adaptation should depend profoundly on the demographic context of selection.

TLDR
This paper considerably broadens the conditions that favor genetic canalization, which so far has only been postulated to evolve under long‐term stabilizing selection.

Predatory cannibalism in Drosophila melanogaster larvae.
TLDR
It is found that under crowded laboratory conditions younger larvae regularly attack and consume 'wandering-stage' conspecifics, forming aggregations mediated by chemical cues from the attacked victim, suggesting predation in Drosophila is a functional, adaptive behaviour which can rapidly evolve in response to nutritional conditions.
