Over recent years, fish parasites of the genus Cymothoa Fabricius, 1793, have received increased attention due to both their ecological and their economic importance to aquaculture and fishery. As the studies about Cymothoa have increased this improve our understanding on the host speci...

Despite being an important component of the freshwater ecosystems and an important factor controlling wild fish populations, Amazonian fish parasites have been poorly studied. Here, we analyzed the fauna of metazoan parasites from 10 detritivorous and omnivorous fish species from Amapá Lake&...

Specimens of Bactrocera carambolae Drew & Hancock, 1994 (Diptera: Tephritidae) were obtained from fruits of Averrhoa bilimbi L., Averrhoa carambola L. (Oxalidaceae), Malpighia emarginata DC. (Malpighiaceae), and Psidium guajava L. (Myrtaceae), from a survey carried out in Lethem, Republic of&#...

O presente estudo registra uma nova ocorrência do camarão-tigre, Penaeus monodon Fabricius, 1798, espécie exótica capturado por pescadores artesanais no estuário do rio Oiapoque, Amapá, a uma profundidade de aproximadamente 25 metros, na plataforma continental da Amazônia oriental.

In this work we report five new host plants of Bactrocera carambolae Drew & Hancock, 1994 as well as new records of hosts of Anastrepha bahiensis Lima, 1937, Anastrepha fraterculus (Wiedemann, 1830), and Anastrepha striata Schiner, 1868 from samplings carried out in Mazagão cou...

Attalea excelsa (urucurizeiro) is a dominant palm of the estuarine floodplains, with great potential for nontimber management. This study evaluated the population dynamics of urucurizeiro and the factors that contribute to colonising of this species in a flooded environment. Individuals with ...

The preservation of tropical forests is increasingly at risk, including forests located within human-modified landscapes that retain high conservation value. People modify and interact with these landscapes through a wide range of uses. However, our knowledge of how different forest uses aff...

Accurate estimates of commercial volume in tropical forests are key for the implementation of sustainable forest management plans. Because of the lack of local or generic volumetric equations, most forest managers and forestry services are still using traditional expansion factors (i.e., mul...
