The evolution of brain size and organization in vertebrates. A program for research
(1994)
In vertebrates, brain size variability relates to two main parameters: body size and ecological factors (in particular diet and foraging strategy). It has been considered by many authors that evolutionary brain growth is ...
Correlated evolution of flower size and seed number in flowering plants (monocotyledons)

Female body size, fecundity parameters and foundation of new colonies in Anelosimus jabaquara (Araneae, Theridiidae)
(Birkhauser Verlag AgBaselSuíça, 2001)
Male-male competition and repeated evolution of terrestrial breeding in Atlantic Coastal Forest frogs*
(2020-02-01)
Terrestrial breeding is a derived condition in frogs, with multiple transitions from an aquatic ancestor. Shifts in reproductive mode often involve changes in habitat use, and these are typically associated with diversification ...
Size-Dependent Selective Mechanisms on Males and Females and the Evolution of Sexual Size Dimorphism in Frogs
(Univ Chicago Press, 2014-12-01)
Sexual size dimorphism (SSD) varies in animals from male biased to female biased. The evolution of SSD is potentially influenced by a number of factors, such as territoriality, fecundity, and temporal breeding patterns ...
SIZE AS A LINE OF LEAST RESISTANCE II: DIRECT SELECTION ON SIZE OR CORRELATED RESPONSE DUE TO CONSTRAINTS?
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
Evolutionary change in New World Monkey (NWM) skulls occurred primarily along the line of least resistance defined by size (including allometric) variation (g(max)). Although the direction of evolution was aligned with ...
Factors influencing the evolution of clutch size in a gregarious insect parasitoid
(WILEY-BLACKWELL, 2000)
1. In this study we examined the clutch size of Hyssopus pallidus (Askew) (Hymenoptera, Eulophidae), a gregarious ectoparasitoid of codling moth (Lepidoptera, Tortricidae) larvae that is characterized by a host handling ...
Uncoupled evolution of male and female cone sizes in an ancient conifer lineage
(University of Chicago Press, 2019-01)
Sexual functions in gymnosperms are mostly performed by separate reproductive structures, which largely reduces sexual interference and sets the scene for morphological and functional sexual specialization. The evolutionary ...
