The Missão de Biologia Marítima (Lisboa, Portugal) and its successor institutions, were responsible for conducting oceanographic campaigns in former Portuguese colonies during the decades of 1950–1960. The primary objective was to advance the systematic study of marine resources in these territories, leading to the collection of thousands of specim...

Marine macroinvertebrate communities play a key role in ecosystem functioning by regulating flows of energy and materials and providing numerous ecosystem services. In Mozambique and São Tomé and Príncipe marine macroinvertebrates are important for the livelihood and food security of local populations. We compiled a dataset on marine invertebrates...

One of the best ways to share and disseminate biodiversity information is through the digitization of data and making it available via online databases. The rapid growth of publicly available biodiversity data is not without problems which may decrease the utility of online databases. In this study we analyze taxonomic, geographic and temporal data...

To enable the process of energy transition towards carbon neutrality, it is important to educate the community on the need for social, economic, environmental and institutional transformation, and to educate and inform citizens to participate proactively in this change. This study evaluated the effectiveness of participation by elementary school st...
Article
Full-text available
The amount of biological data available in online repositories is increasing at an exponential rate. However, data on marine invertebrate biodiversity resources from Mozambique and São Tomé and Príncipe are still sparse and scattered. Online repositories are useful instruments for biodiversity research, as they provide a fast access to data from di...

The amount of biological data available in online repositories is increasing at an exponential rate. However, data on marine invertebrate biodiversity resources are still sparse and scattered in these countries. Online repositories are useful instruments for biodiversity research, as they provide a fast access to data from different sources. The us...

Natural history collections (NHC) worldwide contain vast amount of valuable data that can be used to answer a wide range of questions by exploring biodiversity and natural resources records, having an immense potential to contribute to science, policy making and legislating, and to public scientific awareness. Likewise, the development and increase...
Article
Full-text available
The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009;...

Chapter
Full-text available
The natural history collections are important repositories of biodiversity and fundamental reference systems. They document the diversity of the natural world, allowing to reconstruct a “memory” of natural patterns and processes, providing critical information for the resolution of relevant issues to society such as the effect of climate change, lo...

Article
Full-text available
The growth of Palaemon longirostris H. Milne Edwards, 1837, was studied in Mira River and estuary, SW Portugal, from October 1990 to September 1991. Size was measured as carapace length (CL), total body length (TL), and weight as wet weight (W). Females grew to larger size than males. Carapace length-frequency was used to determine the von Bertalan...
Article
Full-text available
The reproductive traits of female Palaemon longirostris were examined in this study. The mean fecundity was 957±282 SD. The mean egg volume increased 17% from the early to the late development stage. By using the allometric model, no simple volumetric relationship was found between brood size and carapace length at any egg stage. For both early and...

Palaemon longirostris was sampled monthly at 12 sites in the Mira River estuary (southwest Portugal) from October 1990 to September 1991. Animals were counted, measured, and sexed. The estuarine distribution of prawns appeared to follow the salinity displacement, the animals being found at river stations during summer and autumn when saline encroac...
Article

Les stades larvaires du crabe Stenorhynchus lanceolatus sont décrits et comparés à ceux d'autres espèces du genre Stenorhynchus. Les relations entre les genres d'Inachinae, fondées sur les caractères larvaires, et la position de Stenorhynchus sont brièvement discutées.
