Bacopa sessiliflora (Benth.) Edwall (Plantaginaceae) is an aquatic herb that inhabits the banks of watercourses in the Neotropics. In this study, we confirmed the occurrence of the species in the Cerrado following a field collection on the banks of the Preto River, in eastern Maranhão state, Brazil, and the study of herbarium materials. A morpholog...

Nicaragua faces a significant environmental crisis, hosting 7% of global biodiversity and 60% of Central America’s ecosystems. The Bosawás and Indio Maíz Forest Reserves, crucial for endemic species and traditional communities, are under threat due to corruption, crime, and government negligence. The approval of Law No. 953 in June 2017, establishi...

Understanding how functionally similar species segregate resources to minimize competition is vital for predicting evolutionary factors and patterns of coexistence. We conducted a study in Mata de Itamacaoca, in the middle Munim River basin, Maranhão, northeastern Brazil, to characterize the functional morphology and trophic niches of five coexisti...

This study examines the risks associated with relying solely on images for documenting new species records, rediscoveries, taxonomic descriptions, and distribution expansions. We highlight concerns regarding image authenticity, especially in cases where images may be altered, adulterated, or AI (artificial intelligence)-generated, potentially leadi...

Background The Maranhão State harbours great fish diversity, but some areas are still undersampled or little known, such as the Munim River Basin in the northeast of the State. This lack of knowledge is critical when considering anthropogenic impacts on riverine systems especially in the face of major habitat destruction. These pressing threats mea...

The Munim River basin is one of the main river drainages of the Hydrological unit Maranhão, but there are few published studies which focus on ichthyological surveys and taxonomic work within this basin. The present study aims to provide a fish species inventory of the Mata da Itamacaoca, one of the few urban protected areas from the upper Munim Ri...

Nuclear-follower interactions are a particular type of interspecific foraging association which involves a nuclear species, which revolves or scans through the substrate, and follower species that access the food items made available by the nuclear species’ activity. This type of association was observed in a headwater stream at the Itapecuru basin...

We present here the first records of Vanilla bahiana and Vanilla pompona from Maranhão state, northeastern Brazil. Both species were collected in a gallery forest, in areas of Cerrado vegetation at Caxias municipality. This work contributes with knowledge on the geographical distribution of the species in northeastern Brazil.

As complexas inter-relações entre os indivíduos das comunidades de peixes em ambientes dulcícolas e as condições do meio agem como promotores da variedade de adaptações observada. O melhor uso possível da forma corporal e adaptações comportamentais associadas aperfeiçoa a ocupação dos nichos. A funcionalidade e forma da estrutura corporal têm sido...
