Intraspecific density changes the impact of interspecific competitors on parasite infection traits in multiple infections

The paper examines how intraspecific density affects the impact of interspecific competitors on parasite infection traits in multiple infections, finding independent effects on within- and between-host traits.

Competition for food affects the strength of reproductive interference and its consequences for species coexistence.

This study shows that food competition alters reproductive interference between spider mite species, affecting their competitive outcomes and coexistence.

Spider mites collectively avoid plants with cadmium irrespective of their frequency or the presence of competitors

The paper shows that spider mites collectively avoid cadmium-contaminated plants regardless of contamination frequency or competitor presence, but individual mites do not show such preference.

Evolution in response to an abiotic stress shapes species coexistence

The paper shows that evolution in a stressful environment allows two spider mite species to coexist, but evolution of one species in isolation leads to exclusion.

Shaken, not shifted: Genotypic variation tunes how interspecific competition shapes niches

The paper examines genetic variation in spider mite responses to cadmium gradients and interspecific competition, finding genotype-specific effects on niche shaping and resource use.

Limits to the adaptation of herbivorous spider mites to metal accumulation in homogeneous and heterogeneous environments

This study tests whether herbivorous spider mites adapt to cadmium-accumulating plants in homogeneous and heterogeneous environments, finding no adaptation and low genetic variation in measured traits.

Context-dependent effects of temperature and community complexity on trophic interaction strength in a mite community

The paper examines how temperature and community complexity affect trophic interaction strength in a mite community, finding multiplicative effects with context-dependent outcomes.

Trait-specific indirect effects underlie variation in the response of spiders to cannibalistic social partners

The paper investigates how genetic and environmental traits of social partners influence the behavioral response of wolf spiders to conspecific cues, finding that indirect effects drive variation in focal individuals' behavior.

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

This study examines how developmental heat stress affects reproductive success and sex ratio in the haplodiploid spider mite Tetranychus urticae, finding that multiple mating can restore sex ratio but not offspring productivity.

Virulence constrains transmission even in the absence of a genetic trade-off

The study shows that virulence and parasite fitness have a hump-shaped relationship when transmission is not possible, but a positive correlation when transmission occurs, indicating environmental and genetic influences depending on transmission timing.

Specific sequence of arrival promotes coexistence via spatial niche preemption by the weak competitor

The paper shows that the order of species arrival affects competitive outcomes through spatial niche preemption, enabling coexistence of two spider mite species.

Wolbachia and host intrinsic reproductive barriers contribute additively to post-mating isolation in spider mites

This study shows that Wolbachia-induced and host-associated incompatibilities act additively to reduce hybrid production in spider mites, with host factors having a greater impact.

Consequences of population structure for sex allocation and sexual conflict

This study examines how dispersal type and competition scale affect sex allocation and sexual conflict in spider mites, finding that budding dispersal reduces female-biased offspring ratios and male harm.

Population-specific effect of Wolbachia on the cost of fungal infection in spider mites

The paper examines how Wolbachia affects spider mite survival when exposed to fungal pathogens, finding population-specific outcomes.

Creating outbred and inbred populations of haplodiploid mites to measure adaptive responses in the lab

The paper describes methods to create outbred and inbred haplodiploid spider mite populations for studying adaptive responses and heritability.

Inter- and intra-specific variation of spider mite susceptibility to fungal infections: implications for the long-term success of biological control

This study examines inter- and intraspecific variation in spider mite susceptibility to two entomopathogenic fungi across 12 populations, finding significant differences that challenge the use of single fungal strains for biocontrol.

The return of the trophic chain: fundamental vs realized interactions in a simple arthropod food web

The paper investigates whether increasing potential interactions in a simple arthropod food web leads to more complex realized interactions, finding that communities simplify to one or two trophic chains.

Spider mites escape bacterial infection by avoiding contaminated food

This study shows spider mites avoid bacterial-contaminated food and are susceptible to bacterial infections via feeding and spraying, suggesting avoidance behaviors are key to reducing infection risk.

Environments with a high probability of incompatible crosses do not select for mate avoidance in spider mites

The paper investigates whether Wolbachia-induced cytoplasmic incompatibility selects for mate avoidance in spider mites, finding no evolution of mate choice despite genetic variation in mating duration.

Wolbachia both aids and hampers the performance of spider mites on different host plants

This study examines how Wolbachia infection affects spider mite performance on different host plants, finding both positive and negative impacts on life-history traits.

Transgenerational cues about local mate competition affect offspring sex ratios in the spider mite Tetranychus urticae

The paper shows that maternal environment influences offspring sex ratios in spider mites, suggesting females use this as a cue for local mate competition conditions.

Despite reproductive interference, the net outcome of reproductive interactions among spider mite species is not necessarily costly

The study examines reproductive interactions among spider mite species, finding that while mating with heterospecifics can have negative or positive effects on fecundity and sex ratio, the overall net effect is weak.
