Evolution of colour patterns in East African cichlid fish
Journal of Evolutionary Biology - Tập 12 Số 3 - Trang 514-534 - 1999
Abstract African cichlid fishes have undergone outbursts of explosive speciation
in several lakes, accompanied by rapid radiations in coloration and ecology.
Little is known about the evolutionary forces that triggered these events but a
hypothesis, published by Wallace Dominey in 1984, has figured prominently. It
states that the evolution of colour patterns is driven by sexual selection and
that ...
Colour forms of Amazonian cichlid fish represent reproductively isolated species
Journal of Evolutionary Biology - Tập 19 Số 4 - Trang 1139-1148 - 2006
Abstract Laboratory mate choice experiments have confirmed species status for
cichlid fish in the African Great Lakes that differ in colour and little else.
Colour differences between allopatric populations of the South American cichlid
genus Apistogramma are known for many species, yet the status of such
populations has not been previously tested. Analysis of the genetic
relationships and mate ch...
Bursts of transposable elements as an evolutionary driving force
Journal of Evolutionary Biology - Tập 27 Số 12 - Trang 2573-2584 - 2014
AbstractA burst of transposable elements (TEs) is a massive outbreak that may
cause radical genomic rebuilding. This phenomenon has been reported in
connection with the formation of taxonomic groups and species and has therefore
been associated with major evolutionary events in the past. Over the past few
years, several research groups have discovered recent stress‐induced bursts of
differentTEs. ...
Trade-offs between growth and reproduction: an analysis of the quantitative genetic evidence
Journal of Evolutionary Biology - Tập 13 Số 3 - Trang 434-445 - 2000
Abstract The assumption of a trade-off between development time and fecundity,
resulting from a positive correlation between body size and fecundity and
between body size and development time, is a common feature of life history
models. The present paper examines the evidence for such a trade-off as
indicated by genetic correlations between traits. The genetic covariances
between traits are derive...
Getting a grip on the evolution of grasping in musteloid carnivorans: a three‐dimensional analysis of forelimb shape
Journal of Evolutionary Biology - Tập 26 Số 7 - Trang 1521-1535 - 2013
AbstractThe ability to grasp and manipulate is often considered a hallmark of
hominins and associated with the evolution of their bipedal locomotion and tool
use. Yet, many other mammals use their forelimbs to grasp and manipulate
objects. Previous investigations have suggested that grasping may be derived
from digging behaviour, arboreal locomotion or hunting behaviour. Here, we test
the arboreal...
Shape at the cross‐roads: homoplasy and history in the evolution of the carnivoran skull towards herbivory
Journal of Evolutionary Biology - Tập 23 Số 12 - Trang 2579-2594 - 2010
AbstractPatterns of skull shape in Carnivora provide examples of parallel and
convergent evolution for similar ecomorphological adaptations. However, although
most researchers report on skull homoplasies among hypercarnivorous taxa,
evolutionary trends towards herbivory remain largely unexplored. In this study,
we analyse the skull of the living herbivorous carnivorans to evaluate the
importance o...
Recovering speciation and extinction dynamics based on phylogenies
Journal of Evolutionary Biology - Tập 26 Số 6 - Trang 1203-1219 - 2013
AbstractPhylogenetic trees of only extant species contain information about the
underlying speciation and extinction pattern. In this review, I provide an
overview over the different methodologies that recover the speciation and
extinction dynamics from phylogenetic trees. Broadly, the methods can be divided
into two classes: (i) methods using the phylogenetic tree shapes (i.e. trees
without branc...
Strength, diversity and plasticity of postmating reproductive barriers between two hybridizing oak species (Quercus robur L. and Quercus petraea (Matt) Liebl.)
Journal of Evolutionary Biology - Tập 25 Số 1 - Trang 157-173 - 2012
AbstractVery little is known about the nature and strength of reproductive
isolation (RI) in Quercus species, despite extensive research on the estimation
and evolutionary significance of hybridization rates. We characterized
postmating pre‐ and postzygotic RI between two hybridizing oak species, Quercus
robur and Quercus petraea, using a large set of controlled crosses between
different genotypes...
Developmental plasticity, morphological variation and evolvability: a multilevel analysis of morphometric integration in the shape of compound leaves
Journal of Evolutionary Biology - Tập 25 Số 1 - Trang 115-129 - 2012
AbstractThe structure of compound leaves provides flexibility for morphological
change by variation in the shapes, sizes and arrangement of leaflets. Here, we
conduct a multilevel analysis of shape variation in compound leaves to explore
the developmental plasticity and evolutionary potential that are the basis of
diversification in leaf shape. We use the methods of geometric morphometrics to
stud...
Habitat‐dependent geographical variation in ontogenetic allometry of the shiner perch Cymatogaster aggregata Gibbons (Teleostei: Embiotocidae)
Journal of Evolutionary Biology - Tập 20 Số 5 - Trang 1783-1798 - 2007
AbstractStudies of intraspecific morphological variation in fishes have
traditionally focused on freshwater rather than marine species. In addition,
such studies typically focus on adults, although causes and intensities of
selective pressures most likely vary through an individual's lifetime. In this
study, body and head shape of a marine species, shiner perch Cymatogaster
aggregata Gibbons were ...
