Summary: This study aims to analyze the biogeographical events responsible for the distribution of Trichomycterus s.s. by reconstructing the ancestral data based on a time-calibrated multigene phylogeny. It suggests that the modern distribution of Trichomycterus s.s. is a result of different vicariance and dispersal events, with the diversification occurring in the Miocene. The Fluminense ecoregion was separated from other ecoregions by an initial vicariant event, and dispersal events occurred mainly between Paraiba do Sul and neighboring river basins.

Summary: Plant phenology has dramatically shifted in response to climate change, and this shift may have significant ecological consequences. Despite the concern for tropical biomes, we have limited knowledge about phenological responses of tropical plants due to the scarcity of long-term observational datasets. However, we have demonstrated that herbarium specimens can accurately estimate reproductive timing and its spatial variation, making them a vital resource for filling the gap in our phenological knowledge of tropical systems.

Summary: This study utilized remote sensing to analyze spectral responses and land cover change in fragments of Caatinga biome, showing higher SRB in infrared band and lower SRB in red and blue bands in Ouricuri. The classification model had high accuracy in detecting land cover changes in Ouricuri and Taua, indicating its effectiveness in identifying areas most affected by degradation and generating political support for conservation efforts in the Caatinga Biome.

Summary: The Pandeiros wetland in central Brazil is ecologically important for vegetation biodiversity, hydrological cycles, fauna reproduction and feeding, and local human populations. This study investigates the millennial-scale variability of water supply, vegetation structure, and fire activity in the wetland during the Late Holocene. The results show the importance of rainfall in the Pandeiros River basin and Southern Hemisphere in maintaining water supply, as well as the decline in arboreal cover and increase in fire activity in the Cerrado of the Pandeiros Basin.

Summary: A new genus and species, Petrolina bifasciata gen. nov., sp. nov., is described in this study. The species has only two black stripes on the thorax and was collected from fragments of a seasonally dry tropical forest in the state of Pernambuco, northeastern Brazil. The morphology of this new genus and species is similar to Rafaelia Townsend and Malacophagula Bequaert, but the atypical black stripes on the thorax and phallic morphology suggest the proposal of a new genus in the Sarcophaginae subfamily.

Summary: The study aimed to determine the mobile genetic elements involved in the horizontal transfer of erythromycin resistance in Enterococcus faecalis and investigate its transmission ability in heterologous hosts. It was found that a plasmid carrying the erm(T) gene could be transferred to different bacteria and conferred resistance to erythromycin and clindamycin.

Summary: Most pathogens infect multiple host species, but the variation in individual-level impacts of infection remains poorly understood. Using the ectoparasitic mite Sarcoptes scabiei as a model, this study assessed individual-level variation in pathogen impacts across different host species. The study compiled impacts from 77 host species, generated a standardized metric to compare impacts, and identified the most impacted host species.

Summary: Using molecular analysis with mitochondrial and nuclear loci, it is discovered that H. copelandii has two well-defined genetic lineages, which might be related to headwater capture events around 2.8 million years ago. This hidden diversity provides valuable information for taxonomy and conservation in a severely impacted region of Brazil.

Summary: This study investigated the allelopathic potential of different gall morphotypes of Eremanthus erythropappus on Lactuca sativa seeds. It was found that the pentacyclic triterpenes in the extracts of non-galled stems and stem galls had a strong allelopathic effect on seed germination. The galling activity also led to the synthesis and accumulation of new compounds while inhibiting the synthesis of previous compounds.

Summary: The super-host Mimosa gemmulata forms four different galls induced by congeneric Lopesia spp. These galls have distinct morphologies and their development is influenced by the inducer's manipulation of the host plant tissues. Anatomical traits related to trichome differentiation and vascular system arrangement are conserved in M. gemmulata, but altered under the influence of Lopesia spp. The formation of nutritive tissue varies among the different galls and is related to the induction site and original cell lineages. The peculiar traits of the globoid gall are due to its longer lifespan and stronger stimuli-induced responses in all host plant cell lineages.

Summary: The cytological and histochemical features of galls can be changed by parasitoid attack. By studying two tri-trophic systems as models, we found that parasitoids caused distinct cytological responses and had no impact on histochemical profiles of the galls compared to non-parasitized conditions.

Summary: Gall structures and their associated host plants exhibit distinctive structural and histochemical adaptations to survive in the challenging environment of restingas. These adaptations include the presence of thick cuticles, the accumulation of polyphenols and lignified cell walls, and the reorganization of host tissues. Different gall development patterns and host tissue modifications facilitate water accumulation and protect the gall inducers against environmental stresses and enemies.

Summary: Piptocarpha macropoda is a plant species that can develop globoid galls induced by insects. These galls can be attacked by parasitoid insects, which have a positive impact on gall size and nutritive cell layers. However, the parasitoid insects do not affect the size of the host insects, indicating an overstimulation on plant cells and tissues by the parasitized insects.

Summary: Some psyllids transmit 'Candidatus Liberibacter solanacearum', which causes devastating plant diseases in Solanaceae and Apiaceae crops. The recent detection of Bactericera cockerelli and Lso in Ecuador poses a serious threat to these crops in South America. Through a survey in Brazil, potential psyllid vectors and risk scenarios for the spread of Lso were identified, with at least 37 species of psyllids found on Solanaceae and Apiaceae crops and associated weeds.
