Macroevolutionary Patterns in the Aphidini Aphids (Hemiptera: Aphididae): Diversification, Host Association, and Biogeographic Origins
The results suggest that evolution of host alternation within Aphidini may have occurred during the Middle Tertiary (Oligocene) when the secondary hosts emerged.
A comparative study of aggressiveness in eastern North American field cricket species (genus Gryllus)
It is argued that the loss of a tendency to use burrows in G. fultoni and G. vernalis might be related to low levels of aggressiveness in these species, which seems to be the ancestral state in the North American Gryllus phylogeny.
Molecular comparison of Lycorma delicatula (Hemiptera: Fulgoridae) isolates in Korea, China, and Japan
Ultrasonic communication and sexual selection in wax moths: female choice based on energy and asynchrony of male signals
Female evaluation of pulse length and asynchrony interval shows that the insects can distinguish signal events as brief as 150 μs, which may reflect a neural constraint and a mechanical constraint in which the tympanum responds less strongly to pairs of pulses separated by short intervals.
Divergence in female calling song discrimination between sympatric and allopatric populations of the southern wood cricket Gryllus fultoni (Orthoptera: Gryllidae)
The divergent pattern of female phonotactic discrimination between sympatric and far allopatric populations was generally congruent with the pattern of divergence in chirp and pulse rates and would be expected to significantly reduce heterospecific mating in sympatry.
Convergent and divergent patterns of morphological differentiation provide more evidence for reproductive character displacement in a wood cricket Gryllus fultoni (Orthoptera: Gryllidae)
Divergence-enhancing selection may be acting on mirror area as well as calling song characters, whereas local adaptation or clinal effects may explain variation in other morphological characters in sympatric populations of G. fultoni.
Introduced bullfrogs are associated with increased Batrachochytrium dendrobatidis prevalence and reduced occurrence of Korean treefrogs
The presence of L. catesbeianus can now be added to the list of factors responsible for the decline of D. suweonensis populations, and the endangered Dryophytes suwe onensis displays a significantly higher Bd prevalence than the more abundant D. japonicus.
ABSOLUTE VERSUS RELATIVE MEASUREMENTS OF SEXUAL SELECTION: ASSESSING THE CONTRIBUTIONS OF ULTRASONIC SIGNAL CHARACTERS TO MATE ATTRACTION IN LESSER WAX MOTHS, ACHROIA GRISELLA (LEPIDOPTERA: PYRALIDAE)
This work addressed the problem of relative fitness in sexual selection by developing two adjustments of the predictor variables in the multivariate analyses by including group means in addition to absolute values and by using relative values, deviations from group means.
Quantitative genetics of female choice in an ultrasonic pyralid moth, Achroia grisella: variation and evolvability of preference along multiple dimensions of the male advertisement signal
This study highlights the importance of careful preparation of test signals and experimental design for quantifying individual variation in (female) preference along multiple signal dimensions, as this additive genetic variance is one of the genetic assumptions of indirect models of sexual selection.
