The differentiation of workers into morphological castes represents an important evolutionary innovation that is thought to improve division of labor in insect societies. Given the potential benefits of task-related worker differentiation, it is puzzling that physical worker castes, such as soldiers, are extremely rare in social bees and absent in wasps. Following the recent discovery of soldiers in a stingless bee, we studied the occurrence of worker differentiation in 28 stingless bee species from Brazil and found that several species have specialized soldiers for colony defence. Our results reveal that worker differentiation evolved repeatedly during the last ~ 25 million years and coincided with the emergence of parasitic robber bees, a major threat to many stingless bee species. Furthermore, our data suggest that these robbers are a driving force behind the evolution of worker differentiation as targets of robber bees are four times more likely to have nest guards of increased size than non-targets. These findings reveal unexpected diversity in the social organization of stingless bees. |

Recently, the Brazilian government committed to restore and reforest 12 million hectares of forests until 2030 (Nationally DeterminedContribution - NDC). Seeking to strategically subsidize large-scale restoration policies for Brazil, IPEA and TNC, withthe support of EMBRAPA, the Brazilian Ministry of the Environment - MMA and the Deutsche Gesellschaft fur InternationaleZusammenarbeit - GIZ, developed a study to characterize the main ecological restoration techniques applied in distinct biomesof Brazil. The methodology consisted in identifying widely used materials and management activities. To accomplish that, consultationswere made with project executives, academic experts and public managers from various regions of Brazil. We received 94 responses that contributed to the analyzes performed. The result of this evaluation allowed the description of techniques, foreach Brazilian biome, in terms of the following information: main inputs and activities employed; usual amount of inputs andlabor (man-hours) employed; steps in which each input and activity is used (implementation phase and/or maintenance phase)and a general outline of each technique. Our results show large variability in the characteristics of intensive techniques, wellestablished in the technical and scientific literature (e.g., dense tree planting of several species through seedling), as well as intechniques based on natural regeneration. The expressive number of projects reporting use of the latter (both with and withoutmanagement) highlights the search for efficient results in ecological terms at lower cost and with easier implementation, focusingon natural processes and mechanisms of ecosystems recovery.
