Summary: Weed competition can greatly reduce wheat yields, especially in organic systems or with herbicide-resistant weeds. Breeding wheat for increased competitive ability is important, and traits like early vigor and plant height show promise as secondary selection traits that are easier to measure and have higher heritability. Decentralized breeding may be the best approach due to genotype by environment interactions.

Summary: This research study observed changes in growth characteristics and competitive ability of a weed species, Abutilon theophrasti Medik., across multiple generations. The study also investigated changes in sensitivity to herbicides over time. The results indicate that the weed has rapidly evolved increased competitive ability and changes in response to herbicides.

Summary: In this study, three perennial ryegrass populations with suspected resistance to ALS or ACCase herbicides were collected from wheat fields in northwestern Greece. The R1 population showed cross-resistance to certain ALS inhibitors but was susceptible to imazamox. All populations were susceptible to ACCase inhibitors. Analysis of the ALS gene sequence revealed a potential mechanism of target-site mediated resistance. The R1 population displayed similar growth rates and competitive ability against wheat compared to the susceptible population.

Summary: Competition drives evolutionary change across species, but our understanding of how competitive differences among species direct the evolution of interspecific interactions is incomplete. By studying competition between a grass species and an invasive species, we found that populations can evolve increased competitive ability through reduced interspecific or intraspecific competition. Trade-offs do not always constrain the evolution of competitive ability, and the evolution of one species can influence its opponent's competitive ability.

Summary: The study evaluated pea variation for competitive ability and associated traits, as well as the efficiency of four phenotypic or genomic selection strategies. Results showed that a greater pea proportion in mixed cropping was correlated with higher total yield, while delayed flowering and taller plant height had a significant impact on pea yield in mixed cropping. The genetic correlation for pea yield slightly exceeded 0.40 in both mixed stand and pure stand conditions.

Summary: Microorganisms' life-history strategies have a significant impact on the processing of organic carbon, which in turn influences microbial interactions and carbon cycling in soils. High rrn isolates have a greater potential for resource competition and tend to consume a wider variety and larger quantity of substrates compared to low rrn isolates. By connecting bacterial life-history strategies, genomic traits, and metabolism, this study advances our understanding of the links between bacterial community composition and the transformation of carbon in soils.

Summary: Multiple infections in plants, whether simultaneous or sequential, are common and can lead to competitive interactions impacting competitors' traits and fitness. While theoretical frameworks offer insights into potential outcomes on pathogen evolution and disease dynamics, experimental observations suggest unexpected results are possible.

Summary: Recovery rates of parasitic worms increase with life cycle progression, with larger larvae having higher recovery rates. Recovery declines in larger hosts but less than it increases with worm size. Higher doses are used in systems with lower recovery rates, indicating that high doses are chosen when fewer worms are expected to establish infection.

Summary: Studying the interaction between evolutionary and ecological processes can improve our understanding of biological processes such as species interactions, community assembly, and ecosystem functions. This study found that the evolution of competitive traits in a grass species not only affects its own growth and fitness, but also influences the growth of competing species and species diversity. Therefore, eco-evolutionary interactions play a crucial role in natural field environments.

Summary: Ecological stoichiometry provides a useful framework for understanding the effects of nutrient availability on biotic communities. In this study, we focused on the relationship between phosphorus availability and organismal growth and development. Our results show that P-deficient environments lead to predictable changes in important life history traits of soil nematodes, and these changes are mediated by altered rRNA gene copy number and subsequent changes in gene expression and protein synthesis. These findings have implications for understanding soil ecological and evolutionary patterns at multiple levels of organization.

Summary: Interspecific competition can significantly influence the evolutionary trajectories of species in response to changing climates, even after the competition has ended. Competitive interactions may leave a legacy that shapes evolutionary responses to climate, highlighting the complex interplay between competition, evolution, and environmental change.

Summary: Expression of sexual weapons in armed insects is strongly influenced by environmental factors, resulting in significant morphological differences between larger and smaller males. These differences in weapon morphology may promote non-sexual trait variations, with different subsets of multiple traits contributing to the reproductive success of larger and smaller males.

Summary: Populations with different densities show genetically based differences in life histories, where food limitation affects growth, size at birth, maturation, and survival differently. Fish from high-density populations exhibit a greater ability to tolerate low per-capita food availability, attributed partially to their larger size at birth.

Summary: Molecular identification is increasingly used in biodiversity surveys and laboratory experiments, but many groups of organisms face challenges in reliable identification due to lack of sequenced voucher specimens or errors in available sequences. The introduction of the curated open-access molecular reference database DROP for Drosophila parasitoids is a significant step to address this problem, providing accurate identification and improving cross-referencing between studies in this model system. The effort in curating 154 laboratory strains, 856 vouchers, 554 DNA sequences, and other data for 183 operational taxonomic units demonstrates the underestimation of species richness in Drosophila parasitoids and provides an updated taxonomic catalogue for the community.

Summary: Treatment with lisinopril, a renin-angiotensin system inhibitor, shows mixed results in humans due to genetic variation. Genes in the WNT signaling pathway are associated with physical performance and sensitivity to lisinopril treatment. These genes could be potential therapeutic targets for improving resiliency.

Summary: This study compares the abundance of arthropod prey for Florida grasshopper sparrows in dry prairie and pasture habitats and examines the effects of fire year and season on arthropod abundance. The results show that arthropod abundance is higher in pasture than dry prairie, but the mean body length of Orthoptera is smaller in pasture. Additionally, Orthoptera in the dry prairie preferentially select recently burned habitats, suggesting greater resource availability.
