Single-fly assemblies fill major phylogenomic gaps across the Drosophilidae Tree of Life

The paper presents 183 new genome assemblies for 179 drosophilid species using single-fly long-read sequencing, improving phylogenomic coverage and enabling a well-resolved multi-locus phylogeny.

Warming decreases host survival with multiple parasitoids, but parasitoid performance also decreases

The paper examines how warming affects host survival and parasitoid performance in multi-parasitoid systems, finding that while warming enhances top-down control, parasitoid performance declines due to competition.

Microbiome structure of a wild Drosophila community along tropical elevational gradients and comparison to laboratory lines

This study examines microbiome variation in wild and lab-reared Drosophila across elevational gradients, finding that field-collected flies have more diverse microbiomes and elevation explains some variation in microbial communities.

Multiple parasitoid species enhance top-down control, but parasitoid performance is context-dependent

The paper investigates how community structure and species identity affect parasitoid performance and host suppression in a host-parasitoid system, finding that multiple parasitoid species enhance host suppression but performance depends on community composition.

Experimental warming influences species abundances in a Drosophila host community through direct effects on species performance rather than altered competition and parasitism

This study shows that warming directly affects Drosophila host community abundances through species-specific thermal performance, not via changes in competition or parasitism.

Intraspecific variation in symbiont density in an insect-microbe symbiosis

The paper examines variation in symbiont density between host and symbiont genotypes and finds that higher densities correlate with survival costs but not protection against fungus, suggesting antagonistic coevolutionary dynamics.

Fitness effects of competition within and between species change across species' ranges, and reveal limited local adaptation in rainforest Drosophila

This study shows that competition effects vary across species' ranges, with interspecific competition stronger at range edges and intraspecific competition more impactful at range centers, revealing limited local adaptation in rainforest Drosophila.

Molecular analyses reveal consistent food web structure with elevation in rainforest Drosophila - parasitoid communities

The paper builds Drosophila-parasitoid food webs across elevation gradients and finds no significant changes in network structure metrics despite environmental variation.
