RADAR ON RAIA: High frequency radars in the RAIA Observatory

, 2021
The RADAR ON RAIA project aims to update and extend beyond the Galician border the High Frequency (HF) radar network that has been operating since 2011 in the framework of the RAIA Observatory. The Project is allowing the establishment of a cross-border collaboration beyond the physical infrastructure itself, developing a sharing strategy of ...

Teratogenic processes in an embryo without gills and low yolk absorption of Zapteryx brevirostris (Elasmobranchii: Rhinobatidae)

Brazilian Journal of Oceanography, 2015
This is the first report of morphological anomaly in embryos of Zapteryx brevirostris (Lesser guitarfish), a very common species in Brazil. The gills were absent, and the pectoral fins were not fully formed nor were they completely fused to the head ...

Forms of Touch during Medical Encounters with an Advanced Heart Failure (AdHF) Doctor who Practices Relational Medicine

Social Interaction, 2020
Within a participatory research project, we investigate how forms of touch we call caring touch are enacted in AdHF medical encounters. Through the theoretical lens of Relational Ontology (Raia, 2018), grounding multimodality in phenomenology, we ...

Homo luzonensis and the role of homoplasy in the morphology of hominin insular species

Cladistics, EarlyView.
Abstract Homo luzonensis lived during the upper Pleistocene in the northern Philippines, east of the Wallace line. The few specimens attributed to this species show a mosaic of plesiomorphies for the genus Homo and apomorphies found in upper Pleistocene Homo species.

Age and growth of the endemic groovebelly stingray (Dasyatis hypostigma), a heavily exploited batoid in the Brazilian Meridional Margin (21–34° S)

Journal of Fish Biology, EarlyView.
Abstract Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray (Dasyatis hypostigma), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean.

Body Size Evolution in Burying Beetles (Staphylinidae: Silphinae: Nicrophorus)

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Burying beetles (genus Nicrophorus) exhibit broad, skewed variation in body size, which influences carcass use and competitive interactions. Using a large dataset of morphological and geographic data, we show that body size evolution is shaped by phylogenetic history, biogeography, and ecological interactions, with divergence especially pronounced ...

Projections of Atmospheric Moisture Transport Over South America in a Changing Climate

International Journal of Climatology, Volume 46, Issue 2, February 2026.
End‐of‐century (2071–2100) climate projections show significant contrasts in atmospheric moisture over South America, with increased divergence over Northern Chile and Eastern Brazil and stronger convergence over the La Plata and Magdalena basins. Moisture convergence raises risks of extreme rainfall and floods, while divergence intensifies droughts ...

Venous Thromboembolism Risk Score and Pregnancy

Frontiers in Cardiovascular Medicine, 2022
Venous thromboembolism (VTE) is a major contributor to maternal morbidity and mortality worldwide. Pregnancy is associated with the development of a baseline hypercoagulable state.

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...
