Opsin gene duplication in Lepidoptera: retrotransposition, sex linkage, and gene expression

This study annotates opsin genes in 219 Lepidoptera genomes, identifies 44 duplication events, and finds conserved expression of a long-wavelength sensitive retrogene in Noctuoidea.

Logging alters tropical forest structure, while conversion to agriculture reduces biodiversity and functioning

The paper analyzes the impacts of logging and conversion to oil palm on tropical forest structure, biodiversity, and functioning in Borneo, finding that logging affects structure more than biodiversity, while conversion has greater impacts on biodiversity and functioning.

Altered litter and cellulose decomposition across an anthropogenic habitat modification gradient in Sulawesi, Indonesia

The paper measures decomposition of leaf litter and cellulose across different habitat types in Sulawesi, finding reduced decomposition in corn plantations and the importance of litter invertebrates over fungi.

Higher aboveground carbon stocks in mixed-species planted forests than monocultures - a meta-analysis

This study finds mixed-species planted forests store more aboveground carbon than monocultures, with higher carbon stocks in more diverse mixtures.

Selective logging shows no impact on the dietary breadth of the fawn leaf-nosed bat (Hipposideros cervinus)

The study examines the diet of fawn leaf-nosed bats across logging disturbance gradients in Borneo, finding no significant impact on dietary breadth.

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.

Opposing mechanisms of competition determine species invasions and functional diversity

The paper investigates how trait differences between invasive and resident ant species influence competition and functional diversity through opposing mechanisms.

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.

Natural enemies have inconsistent impacts on the coexistence of competing species

The paper tests how a generalist natural enemy affects coexistence of competing insect species and finds that parasitism impacts coexistence through fitness differences, not niche differences, with no overall trade-off between reproductive rate and susceptibility.

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.

Altered structure and stability of bat-prey interaction networks in logged tropical forests revealed by metabarcoding

This study shows that logging reduces prey diversity in insectivorous bats and alters their interaction networks, making ecosystems less stable.

Trait-similarity and trait-hierarchy jointly determine co-occurrences of resident and invasive ant species

The paper shows that trait-similarity and trait-hierarchy jointly explain co-occurrence patterns between invasive and resident ant species.

Movement of moths through riparian reserves within oil palm plantations

The paper investigates moth movement in riparian reserves within oil palm plantations, finding moths preferentially use riparian reserves over oil palm matrix for movement.

The cryptic impacts of invasion: Functional homogenization of tropical ant communities by invasive fire ants

This study examines how invasive fire ants impact the functional diversity of tropical ant communities, finding increased functional homogenization and reduced uniqueness despite minimal taxonomic changes.
