Summary: This study examined two functionally distinct Eupristina wasp species associated with Ficus microcarpa in Yunnan Province, China, revealing one as a competent pollinator and the other as a parasitic species dramatically impacting the reproductive success of its host. The parasitic species displayed greater relative fitness in competitions with the pollinators, and phylogenetic analyses suggested their sister taxon relationship. Unlike existing studies, this research found no evidence of host sanctions affecting the reproductive success of nonpollinating wasps, likely promoting the evolution of cheating.

Summary: Research on fig wasps has contributed significantly to understanding insect-plant interactions, but the molecular mechanisms of fig wasp host specificity remain poorly understood. This study presents a large-scale transcriptomic dataset of 25 fig wasp species, revealing potential genetic mechanisms underlying specific host adaptation. The findings shed light on the evolutionary diversification and host specificity of fig wasps, and contribute to the growing dataset on fig wasp genomics.

Summary: The vegetative and reproductive growth of plants play a crucial role in regulating the interactions within an ecosystem. In the case of plant-insect interactions, plants use visual and chemical cues to signal their reproductive period. Ficus mutualism, however, relies solely on chemical cues for the figs to attract pollinating wasps. This study examines the phenological pattern and volatile compound emissions of Ficus septica in Central Taiwan. The results show that the fig species displays continuous growth throughout the year, with a decrease in winter. The emissions of odor blends from male and female trees are similar, but with seasonal variations, and are influenced by the size of the wasp population.

Summary: Effective conservation of ecological communities requires accurate and up-to-date information about the persistence or decline of species. While the persistence of the whole community network is essential, only small subsets of these networks can be monitored. Establishing links between small data snapshots and the bigger picture conclusions about ecosystem health is urgently needed.

Summary: Obligate pollination mutualisms often exhibit high species specificity, but host sharing and pollinator sharing can occur in current ecological time. This study used genome-wide sequence data to investigate the impact of departures from strict specificity on hybridization and introgression in Panamanian fig species and their associated wasp species. The results showed ongoing hybridization and historical introgression in fig species, but no evidence of hybridization or introgression in the associated wasp species. This suggests that pollinators in obligate pollination mutualisms are reproductively isolated even when different species mate in shared hosts.

Summary: Active pollination has evolved four times in brood site pollination mutualisms. In male figs, the wasp inserts its ovipositor into the flower and deposits a pollen grain on the hypopygium, resulting in flower pollination and insect oviposition. In female figs, the wasp's pollination behavior occurs less frequently but lasts longer, ensuring efficient ovule fertilization.

Summary: Recent theoretical work has provided new insights into the organization of species interactions in food webs. However, the role of higher plants, such as trees, in terrestrial ecosystems has been overlooked. Trees are fundamentally different from algae, the main plants in freshwater and marine systems, and play a crucial role in providing nutrients for diverse species. It is important to integrate the understanding of plant communities into food web studies to gain a more comprehensive understanding of terrestrial ecosystems.

Summary: This study found that ants can contribute to pollination of female plants in dioecious, wind-pollinated species, particularly in cases where the distance between male and female plants is greater. While wind pollination remains the main pollination mechanism, ants play a significant role in offsetting pollen limitation in isolated female plants.

Summary: Pollination and seed dispersal by animals are crucial for plant diversity and ecosystem functioning. This study examines the evolution of mutualistic behaviors in lizards, revealing the repeated evolution of flower visitation and seed dispersal in these species. The findings suggest a potential evolutionary mechanism behind the emergence of double mutualisms, with seed dispersal activity pre-dating flower visitation.

Summary: The study revealed that environmentally friendly agricultural practices enhance the representation of mutualistic and predation network motifs, while intensive agriculture favors intraguild predation interactions. The frequencies of motifs representing antagonistic interactions were more inconsistent and unpredictable across sites than mutualistic motifs, especially on intensified farms.

Summary: This study investigates the geographic variation of floral odour in the mutualism between Ficus hirta and its pollinators. The results show progressive divergence of floral odours, which is driven by plants and followed by insects. The variation is not influenced by the insects and fits the genetic structure of the plant.

Summary: The study shows that there are fitness costs for fig wasps that do not pollinate, mainly due to abortions of unpollinated figs and reduced development of wasp larvae to adults. The relative fitness of non-pollinating wasps compared to pollinating wasps is 0.59, leading to an intermediate sanction strength of 0.41. In addition, fig species with stronger host sanctions had fewer uncooperative wasps among their pollinators, suggesting that sanctions promote cooperation.

Summary: Some nectarivorous mammals prefer low-concentration ethanol solutions, but the behavioral responses of nectar-feeding birds to ethanol are unknown. In experiments with Anna's Hummingbirds, it was found that they did not discriminate between 0% and 1% ethanol solutions, but consumption rates significantly decreased with a 2% ethanol solution.

Summary: The study found that larger eggs are more likely to be fertilized and develop into female offspring, while smaller eggs are more likely to remain unfertilized and become male offspring. Mating increases female investment in egg size, enhancing fertilization success and female offspring survival but reducing lifetime fecundity. This suggests a reproductive strategy favoring increased daughter production, potentially conflicting with the optimal offspring sex ratio.

Summary: In haplodiploid animals, females can face constraints in producing female offspring due to factors such as insemination failure or physiological limitations. Research on Pezothrips kellyanus revealed that constrained sex allocation occurs in small females producing smaller eggs, while large females producing larger eggs tend to have a female-biased sex ratio. This bimodal sex allocation pattern is correlated with maternal condition and may be related to an egg size-mediated fertilization mechanism in haplodiploids.

Summary: This study provides a detailed description of the life cycle, nesting biology, and social organization of a progressive provisioning allodapine bee in the Greater Sydney region. The research revealed the presence of multiple adult female bees in most nests, indicating reproductive division of labor and sex allocation patterns in this population. Multi-female nests showed evidence of reproductive dominance hierarchies and higher brood production compared to single-female nests.

Summary: Many insects delay egg-laying to optimize their reproductive effort. This study focused on thrips and found that delaying oviposition did not impact egg size, but increased egg load and quantity. Delayed oviposition did not affect offspring fitness or sex ratio. This suggests that thrips females can delay oviposition without incurring physiological costs.

Summary: This study observed the foraging behavior of 69,354 invertebrate flower visitors in Australian orchards and found that native stingless bees and introduced honey bees were the most abundant and efficacious pollinators. However, tree-nesting stingless bees decreased with distance from native forest and their distribution limits pollination service in other major Australian apple-producing regions. More broadly distributed native bees transferred the most pollen per-visit, but their low abundances resulted in a general reliance on honey bees for apple pollination.

Summary: The study found that in P. minerva, the ratio of winged males to unmated females closely matches, providing strong quantitative support for Hamilton's simple Mendelian model. There was no evidence for other factors that could violate simplifying assumptions of the model, and the proportion of winged males was not correlated with the number of wasps per fig, indicating no evidence for a conditional strategy.
