Multiple mating rescues offspring sex ratio but not productivity in a haplodiploid exposed to developmental heat stress

Functional Ecology, Volume 37, Issue 5, Page 1291-1303, May 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Reproduction is generally more sensitive to high temperatures than survival and arguably a better predictor of the response of populations to climate change than survival estimates.

Dispersal kernel of green rice leafhopper estimated from truncated data

Population Ecology, Volume 65, Issue 2, Page 111-120, April 2023., 2023
Using truncated mark‐recapture data at three host plant development stages (seedling, tillering, and heading), we estimated untruncated parameters of the normal and exponential dispersal kernels for green rice leafhopper by maximum likelihood and the method of moments.

Ancestral polymorphisms explain the role of chromosomal inversions in speciation. [PDF]

PLoS Genetics, 2018
Understanding the role of chromosomal inversions in speciation is a fundamental problem in evolutionary genetics. Here, we perform a comprehensive reconstruction of the evolutionary histories of the chromosomal inversions in Drosophila persimilis and D ...

Species interactions and diversity: a unified framework using Hill numbers

Oikos, Volume 2023, Issue 3, March 2023., 2023
Biodiversity describes the variety of organisms on planet earth. Ecologists have long hoped for a synthesis between analyses of biodiversity and analyses of biotic interactions among species, such as predation, competition and mutualism. However, it is often unclear how to connect details of these interactions with complex modern analyses of ...

Large introns in relation to alternative splicing and gene evolution: a case study of Drosophila bruno-3 [PDF]

, 2009
Background: Alternative splicing (AS) of maturing mRNA can generate structurally and functionally distinct transcripts from the same gene. Recent bioinformatic analyses of available genome databases inferred a positive correlation between intron length ...

SELECTION BY FERTILITY IN DROSOPHILA PSEUDOOBSCURA [PDF]

Genetics, 1974
ABSTRACT Fertility, the component of selection due to female fecundity and male mating success, differed significantly among the ST/ST, ST/AR, and AR/AR karyotypes in experimental populations and varied with karyotypic frequency. In relation to ST/AR, ST/ST females and males had higher fertilities at low frequency; AR/AR males and ...

The Drosophila‐parasitizing wasp Leptopilina heterotoma: A comprehensive model system in ecology and evolution

Ecology and Evolution, Volume 13, Issue 1, January 2023., 2023
The parasitoid Leptopilina heterotoma has been used as a model system in biology for more than 70 years. This review aims to provide a broad and detailed synthesis of the work performed on this system, including immunity, behavioral ecology, endosymbiotic and trophic interactions, as well as physiology.

De novo transcriptome assembly reveals sex-specific selection acting on evolving neo-sex chromosomes in Drosophila miranda. [PDF]

, 2014
BackgroundThe Drosophila miranda neo-sex chromosome system is a useful resource for studying recently evolved sex chromosomes. However, the neo-Y genomic assembly is fragmented due to the accumulation of repetitive sequence.

Resource availability modulates the effect of body size on reproductive development

Ecology and Evolution, Volume 13, Issue 1, January 2023., 2023
We attempted to untangle the body size—fitness trait correlations with Hydra oligactis model system, by grafting procedure to directly manipulate body size, and with food availability manipulation. With these treatments, we attempted to reveal the effects of body size, resource availability, and their interaction on reproduction and survival.
