Cichlid fishes are famous for large, diverse and replicated adaptive radiations in the Great Lakes of East Africa. To understand molecular mechanisms underlying cichlid phenotypic diversity, we sequenced genomes transcriptomes five lineages African cichlids: Nile tilapia (Oreochromis niloticus), an ancestral lineage with low diversity; four members lineage: Neolamprologus brichardi/pulcher (older radiation, Lake Tanganyika), Metriaclima zebra (recent Malawi), Pundamilia nyererei (very recent...
Earth's biodiversity is still so poorly known that only about two million (Bánki et al., 2021) of the estimated nine or more eukaryotic species (Larsen 2017; Mora 2011) have been described. This puts taxonomists in a race against time to discover before it lost as result Anthropocene mass extinction. Each description an often long and time-consuming process has involved collecting specimens, processing them, discovering their correct place tree life describing its diagnostic characters from...
How variation in the genome translates into biological diversity and new species originate has endured as mystery of mysteries evolutionary biology. African cichlid fishes are prime model systems to address speciation-related questions for their remarkable taxonomic phenotypic diversity, possible role gene flow this process. Here, we capitalize on sequencing phylogenomic analyses relative impacts incomplete lineage sorting, introgression hybrid speciation Neolamprologus savoryi-complex (the...
Abstract Environmental DNA (eDNA) metabarcoding has revolutionized ecological and environmental research by describing communities without relying on direct observations, making it a powerful, non-invasive, cost-effective tool in biodiversity monitoring. However, implementation of eDNA as standard protocol long-term monitoring programs, that have traditionally relied capture-based methods, poses challenges terms data comparability. Here, we compared freshwater fish assessed through...
Abstract Freshwater snails play a key role in the transmission of schistosomiasis, tropical parasitic disease affecting over 150 million people. Adaptation these to local climatic conditions is critical factor determining how climate change and other environmental factors influence dynamics, yet this potential adaptation has remained unexplored. Bulinus truncatus schistosome intermediate host snail with widest geographic distribution therefore an important maximum range urogenital...
The Iberian Peninsula, in southwestern Europe, is home to a distinctive freshwater fish fauna, predominantly composed of endemic species. This consequence the prolonged isolation from western Europe caused by Pyrenees, diverse geological and climatic gradients, river basins. Freshwater diadromous fishes have diversified Peninsula include 72 currently recognized native species, 50 which are region. Habitat loss degradation, introduction invasive climate change placed among most threatened...
Background: Schistosomiasis, a parasitic disease caused by Schistosoma trematodes, remains significant public health burden in sub-Saharan Africa, particularly regions with limited access to clean water, sanitation and hygiene. Effective control strategies rely on large-scale surveillance accurately identify target high-risk populations. However, traditional methods such as malacological surveys stool/urine microscopy humans often lack sensitivity scalability. Environmental DNA (eDNA) is...
Environmental DNA (eDNA) metagenomics sequences all molecules present in environmental samples and has the potential of identifying virtually any organism from which they are derived. However, due to unacceptable levels false positives negatives, this approach is underexplored as a tool for biodiversity monitoring across tree life, particularly non-microscopic eukaryotes. We SeqIDist, framework that combines multilocus BLAST matches against several reference databases followed by an analysis...
Roughly 18,000 species are described annually as new to science, while estimated extinction rates comparable or even exceeding these discoveries. Considering the estimates of up 15 million extant eukaryotic on Earth, which only about 2 have been so far, there has a recent 'boom' potential approaches more quickly discover and describe millions unknown species. This deficit is particularly noted in hyperdiverse taxa, current rate discovery considered too slow. Recently, 'minimalist' alpha...
Updating information on the distribution of recently introduced and other poorly known non-natives is essential to prevent control their spread better address biological invasions.Here, we combine scientific citizen science data update five arrived (i.e., < 25 years), non-native fish species (Alburnus alburnus, Ameiurus melas, Rutilus rutilus, Sander lucioperca Silurus glanis) one rare, longer established > 50 (Esox lucius) in Portugal.These have been increasingly targeted by recreational...

The evolution of species boundaries and the relative impact selection gene flow on genomic divergence are best studied in populations pairs exhibiting various levels along speciation continuum. We Iberian barbels, Barbus Luciobarbus, a system spanning wide degree genetic relatedness, as well geographic distribution range overlap. jointly analyze multiple types molecular markers morphological traits to gain comprehensive perspective nature these cyprinid fishes.
Abstract Freshwater snails are pivotal in transmitting schistosomiasis, a tropical parasitic disease affecting over 150 million people. The adaptive potential of these is critical factor determining how climate change and other environmental factors influence transmission dynamics, yet it has remained unexplored.

Our understanding of animal communication has been largely driven by advances in theory since empirical evidence difficult to obtain. Costly signaling became the dominant paradigm explaining evolution honest signals, according which reliability relies on differential costs imposed signalers distinguish animals different quality. On other hand, mathematical models disagree source at equilibrium. Here, we present an framework study signals that generates predictions form, function, and sources...
Thirty paralog-specific primers were developed, following an intron-primed exon-crossing strategy, for S7 and growth hormone genes in Barbus (subgenera Luciobarbus). We found that amplification requires the use of only one primer, allowing their simultaneous with universal exon-primed intron-crossing broad taxonomic applicability. This hybrid annealing strategy guarantees both specificity generality reactions represents a step forward duplicated nuclear loci polyploid organisms members...
Hybridization between native and nonnative fish species is a major conservation issue, especially in ecosystems with high levels of endemism, such as Iberian streams. To date, hybridization the invasive bleak Alburnus alburnus has been reported for chub Squalius alburnoides S. pyrenaicus scattered locations only. However, spreading region, potentially increasing risks other species. gather more comprehensive picture on current geography hybridization, we compiled records hybrids Portugal...
The North American catfish Ameiurus melas is recorded for the first time in Portugal. Its presence Tagus River Basin probably due to natural spread of individuals from Spanish populations, while episodic translocation could explain its occurence previously non‐invaded Guadiana and Sado basins.
