Summary: A new spirurid nematode, Protospirura canariensis n. sp., was described as a parasite of the black rat Rattus rattus in El Hierro Island, Spain. The distinguishing characteristics of P. canariensis n. sp. from other Protospirura species include the number of tooth-like outgrowths in the pseudolabia, the size and arrangement of male spicules, and the number and arrangement of cloacal papillae. Molecular phylogenetic analysis was conducted on the new species and compared with related species.

Summary: The 'western seed bug' is a global invasive species that has rapidly expanded worldwide and become an important pest for coniferous forests. The early detection of this species in the Canary Islands allows for understanding the potential damage it may cause to the natural endemic pine forests, which are prevalent on the islands.

Summary: The high variability in floral traits is driven by adaptation to pollinators and competition among co-flowering species. In the Mediterranean community, flower size serves as the most honest signal for pollinators, while nectar concentration is positively associated with chromatic contrast. This study demonstrates the correlation between rewards and visual signals perceived by bees, indicating a community-specific association.

Summary: Anthocyanins play a crucial role in determining flower color diversity in angiosperms, with differential expression of specific structural and regulatory genes identified in blue- and orange-petaled individuals of Lysimachia arvensis. The shift from blue to orange petals is associated with changes in expression of key genes involved in anthocyanin biosynthesis pathway, as well as amino acid substitutions in enzymes affecting substrate specificity. This study highlights the complex genetic and physiological consequences of flower color polymorphism in L. arvensis.

Summary: Flower colour is determined by the presence and type of pigments, with pollinator preferences influencing selection pressure on flower colour. Understanding how pollinators perceive flowers with different pigments is crucial for plant-pollinator communication and flower colour evolution. Research shows that different pigment groups occupy distinct regions in pollinator colour space models, with similar differences in colour conspicuousness among the groups in bee, fly, butterfly, and bird visual space models.

Summary: The genetic divergence between species depends on reproductive isolation (RI) caused by traits reducing interspecific mating (prezygotic isolation) or reduced hybrid fitness (postzygotic isolation). Prezygotic barriers were found to be generally stronger than postzygotic barriers, but previous studies mostly examined F-1 hybrid fitness in early life cycle stages. This study combined field and experimental data to assess the strength of 17 prezygotic and postzygotic reproductive barriers between co-occurring Lysimachia species. The results showed near complete RI between the two species, with prezygotic barriers contributing more in reducing gene flow in allopatry, while their contributions were more similar in sympatry. The strength of postzygotic RI was underestimated when effects on late stages of the life cycle were disregarded.

Summary: Within a community, co-occurring plant species can both diverge and benefit from floral signal standardisation, depending on the flower colour display and flowering phenology. In highly diverse tropical and temperate vegetation types, the visual similarity of rewarding flowers among co-occurring species was investigated. Flower colour was generally not distinguishable within groups by bees, and the flowering periods overlapped in Mediterranean species but tended to be segregated in Brazilian campo rupestre species. The standardisation of floral colour signal within these two species-rich plant communities is advantageous for most of the species studied, despite different flowering phenologies.

Summary: Flower color is a primary attractant for pollinators and varies depending on the vegetation type and background, influencing the perception of flower color by pollinators like bees. Natural background colors affect bee discrimination of flower colors, highlighting the importance of considering environmental factors in analyzing flower color signals.
