Summary: The study found that in plants of the Malpighiaceae family, the behavior of illegally collecting oil resources is as common as the legitimate collection behavior of bees, and this illegitimate collection is more common in lower latitude areas.

Summary: This study explores the reproductive strategy of oil-rewarding flowers and the mutualistic interaction between corbiculate bees and Cymbidium aloifolium. Successful pollination requires honeybees to learn how to access the reward, displaying their cognitive ability. Morphometric matching and absence of competition are important factors for pollination success. This study highlights the importance of exploring the spectrum of pollination rewards pursued by honeybees.

Summary: This study investigates how floral host preference influences the diversification of eucerine bees. The results show that multiple evolutionary transitions from host plants with accessible pollen to restricted pollen from 'bee-flowers' have significantly increased the diversification of a bee clade.

Summary: Since the first descriptions of the floral oil syndrome by Stefan Vogel, substantial knowledge has been obtained on the taxonomic distribution, morphologies and phylogenetics involved in floral oil-mediated interactions. Brazilian research on oil-collecting bees and oil-secreting plants has played a crucial role in this expansion. Future directions for a broader understanding of these interactions are also indicated.

Summary: This study describes the pollination of Moldenhawera nutans and explores its potential floral mimicry toward Malpighiaceae flowers. The investigation revealed that M. nutans is pollinated by bees of the genera Centris and Xylocopa. Compelling evidence supporting the hypothesis of floral mimicry was found.

Summary: Caffeine, a widely occurring plant defense chemical found in the nectar of some plants, influences pollinator behavior and enhances pollination. Bees fed caffeine form longer lasting olfactory memory and are more likely to revisit caffeinated targets, suggesting caffeine can improve memory and act as a reward for these insects.

Summary: The study identified the most important pollinators of Cardiocrinum cordatum as the bumblebee, sweat bee, and marmalade hoverfly, while the contribution of a flower-visiting ant species was found to be small. The research also highlighted the need for more information on flower-visiting species to accurately assess pollination contribution.

Summary: The emergence of animal societies is a major evolutionary transition, and in this study, the researchers explored how and why bees acquire new foraging techniques and whether eusociality facilitates this shift. The results suggest that social bees, particularly long-lived colonies with abundant foragers, are more likely to learn and exploit complex flowers.

Summary: The study investigates the adaptive significance of horizontal flower orientation in radially symmetrical flowers and its effects on pollinator behavior and pollen damage avoidance. The results show that horizontally oriented flowers receive more pollinator visits and have better pollen rain damage avoidance compared to upward-oriented flowers. This suggests that horizontal flower orientation is adaptive and beneficial for insect-pollinated flowers during the rainy season.

Summary: The Neotropical orchid genus Sarcoglottis, with approximately 40 species emitting strong floral scents, relies on nectar-seeking orchid bees such as Eulaema atleticana and E. niveofasciata for pollination. The floral scent of Sarcoglottis acaulis signals the presence of nectar, attracting the bees despite not triggering stereotyped scent-gathering behavior. This self-compatible plant depends on pollinators to increase fruit set, with attributes like low nectar amount and steady-state flowering contributing to its high fruit set.

Summary: Showy flowers play a key role in attracting naive, first-time pollinators. They function as visual signals to entice pollinators to visit and determine if the experience is rewarding. This is similar to how a restaurant uses a large sign and showy visual signals to attract first-time customers when competing with other establishments.

Summary: Flowering plants have evolved diverse metabolites to facilitate interactions with pollinators, providing visual and olfactory signals as well as unique rewards. These specialized metabolites have evolved in specific lineages in response to selection pressures in different niches. Advances in multi-omics technologies have allowed for the discovery of a growing repertoire of these metabolites and the molecular basis of their synthesis and evolution across various plant lineages. This perspective article discusses these aspects, their ecological and evolutionary relevance, and provides an introduction to omics-guided approaches for studying specialized metabolites.

Summary: The extreme dwarfing of red deer on Jersey is the expected outcome of high mutational variance, high immigration rate, a wide adaptive landscape, low levels of inbreeding, and high phenotypic plasticity (in the early phase of dwarfing), all occurring within a time window of around 6 kyr. Our model reveals how extreme dwarfism is a plausible outcome of common, well-known evolutionary processes.

Summary: The increase in global transport has led to the expansion of species adapted to human-altered environments, causing a decline or extinction of endemic species. This study reports the first occurrence of the Afrotropical fly Zaprionus tuberculatus Malloch in the Americas, with potential impacts on drosophilid communities. The invasive species was found in urban parks and natural reserves in the Brazilian Savanna, indicating a rise in its relative abundance and raising concerns about the diversity of drosophilids in the Neotropics.

Summary: Protected areas are important tools for biodiversity and ecosystem conservation, but megadiverse countries face challenges in managing and expanding these areas due to increasing human pressures. The Brazilian Cerrado biome, a biodiversity hotspot, has a small percentage of its land area under strict protections. The Brazilian Long-Term Ecological Research Program monitors long-term changes in protected and non-protected areas in Brazilian biomes. The findings reveal that even within a protected area, changes in the surrounding landscape can impact biodiversity and ecosystem functions, emphasizing the importance of continuous monitoring for conservation.

Summary: There is a significant time difference in the establishment of non-native populations of the giant African snail in different geographic regions. Using distribution models and environmental analysis, researchers found that the expansion of the snail's climatic niche was influenced by its spread and that temperature played a key role in explaining its distribution in the Neotropical region.

Summary: Investigation on the relationship between plants and fruit flies in a commercial fruit and vegetable distribution center in Brazil revealed that the fruit fly assemblages were dominated by exotic species, which were able to infest a wider range of host plants, especially those of exotic origin. This phenomenon is concerning as it can lead to the extinction of native fruit flies and the homogenization of fruit fly communities on a larger scale.

Summary: In this study, the occurrence of spotted wing drosophila (SWD) in the central region of Brazil was investigated, and 20 drosophilid species were detected, most of which are exotic in the Neotropical region. The abundance of SWD fluctuated greatly throughout the year, with the highest abundance observed in April during the rainy season. Potential distribution models indicate that suitable areas for SWD spread will decrease in the south and southeast but increase in the central region of Brazil. Continuous monitoring and improved bioclimatic forecast models are recommended for mitigating damage to local fruit production.

Summary: This study provides the first description of the variation in population density of the Giant African Snail in the Neotropical region. The results show that the density of the snails is influenced by climatic variations, especially the Mean Temperature of the Coldest Quarter and Annual Precipitation. Additionally, low densities can occur in various environmental conditions, whereas medium and high densities seem to appear in more specific climatic combinations.
