The salivary glands of hematophagous arthropods possess a remarkable molecular diversity, reflecting evolutionary adaptations to blood feeding lifestyle and vector-host interactions. In this study, we characterized the salivary-gland transcriptome of adult female Simulium pertinax , a medically important black fly species widely distributed in South America. Through RNA sequencing and bioinformatics analyses, we identified 15,...

The Tagus Estuary is one of the largest in Europe with 320 km 2 , and it has been, for centuries, a gateway to Lisbon. This study focuses on the Moita-Montijo Bay and on the recent dynamics of its tidal flats and saltmarshes. Aerial photographs, orthomosaics, and very high-resolution satellite imagery were used to analyze landcover and shoreline changes. Tidal flats have shown expansion from 1977 to 1995, but since then, contr...

Usher syndrome (USH) is a condition characterized by ciliary dysfunction leading to retinal degeneration and hearing/vestibular loss. Putative olfactory deficits in humans have been documented at the psychophysical level and remain to be proven at the neurophysiological level. Thus, we aimed to study USH olfactory impairment using functional magnetic resonance imaging. We analyzed differences in whole-brain responses between 2...

Summary Anaerobic degradation of long‐chain fatty acids (LCFA) involves syntrophic bacteria and methanogens, but facultative anaerobic bacteria (FAB) might have a relevant role as well. Here we investigated oleate degradation by a syntrophic synthetic co‐culture of Syntrophomonas zehnderi (Sz) and Methanobacterium formicicum (Mf) and FAB (two oleate‐degrading Pseudomonas spp. I1 + I2). Sz + Mf were first cultivated in a contin...

Aim Free‐living bacteria have long been assumed to have little biogeographic signature because of their high potential for passive dispersal. Raphidiopsis raciborskii and Microcystis aeruginosa are free‐living cosmopolitan cyanobacteria with a probable tropical origin, that frequently form toxic blooms and are considered invasive species in middle latitudes. Despite these similarities, their phylogeographic patterns have seldo...
