Abstract Hybridization allows adaptations to be shared among lineages and may trigger the evolution of new species 1,2 . However, convincing examples homoploid hybrid speciation remain rare because it is challenging demonstrate that hybridization was crucial in generating reproductive isolation 3 Here we combine population genomic analysis with quantitative trait locus mapping species-specific traits examine a case Heliconius butterflies. We show elevatus sympatric both parents has persisted...
Quantifying the spatial distribution of taxa is an important prerequisite for preservation biodiversity, and can provide a baseline against which to measure impacts climate change. Here we analyse patterns marine mammal species richness based on predictions global distributional ranges 115 species, including all extant pinnipeds cetaceans. We used environmental suitability model specifically designed address paucity data many species. generated by overlaying predicted distributions species;...
Abstract Is there only one electric eel species? For two and a half centuries since its description by Linnaeus, Electrophorus electricus has captivated humankind capacity to generate strong discharges. Despite the importance of in multiple fields science, possibility additional species-level diversity genus, which could also reveal hidden variety substances bioelectrogenic functions, hitherto not been explored. Here, based on overwhelming patterns genetic, morphological, ecological data, we...
Abstract The current capacity of environmental DNA (eDNA) to provide accurate insights into the biodiversity megadiverse regions (e.g., Neotropics) requires further evaluation ensure its reliability for long‐term monitoring. In this study, we first evaluated taxonomic resolution capabilities a short fragment from 12S rRNA gene widely used in fish eDNA metabarcoding studies, and then compared data water samples with traditional sampling using nets. For discriminatory power analysis,...
Abstract. The bloodsucking adult females of Phlebotomus perniciosus Newstead and P. longicuspis Nitzulescu (Diptera: Psychodidae) are important vectors the protozoan Leishmania infantum Nicolle (Kinetoplastida: Trypanosomatidae) in western Mediterranean countries. species status two phlebotomine sandflies was assessed, along with epidemiological implications. Individual from three Moroccan Rif populations were characterized morphologically, isoenzymatically (by isoelectrofocusing alleles at...
The family Carcharhinidae includes the most typical and recognizable sharks, although its internal classification is subject of extensive debate. In particular, type genus, Carcharhinus Blainville, 1816, which also speciose, appears to be paraphyletic in relation a number morphologically distinct taxa. Isogomphodon oxyrhynchus (Valenciennes, 1839) (the daggernose shark) carcharinid, endemic limited area Western Atlantic between Trinidad Tobago Gulf Maranhão northern Brazil, one smallest...
Abstract In the face of global ecosystem changes driven by anthropogenic activities, effective biomonitoring strategies are crucial for mitigating impacts on vulnerable aquatic habitats. Time series analysis underscores a great significance in understanding dynamic nature marine ecosystems, especially amidst climate change disrupting established seasonal patterns. Focusing Norway's Oslo fjord, our research utilises eDNA-based monitoring temporal biodiversity during one year period, with...
Abstract In many animals, mate choice is important for the maintenance of reproductive isolation between species. Traits and behavioral are predicted to be under strong stabilizing selection within species; however, such traits can also exhibit variation at population level driven by neutral adaptive evolutionary processes. Here, we describe patterns divergence among androconial genital chemical profiles inter‐ intraspecific levels in mimetic Heliconius butterflies. Most bouquets was found...
Abstract The coastline of Sub‐Saharan Africa hosts highly diverse fish communities great conservation value, which are also key resources for local livelihoods. However, many costal ecosystems threatened by overexploitation and their state is frequently unknown due to vast spatial extent limited monitoring budgets. Here, we evaluated the potential citizen science‐based eDNA surveys alleviate such chronic data deficiencies assessed in Mozambique using two 12S metabarcoding primer sets....
Abstract The cephalopod fauna of the southwestern Atlantic is especially poorly-known because sampling mostly limited to commercial net-fishing operations that are relatively inefficient at obtaining cephalopods associated with complex benthic substrates. Cephalopods have been identified in diets many large marine species but, as few hard structures survive digestion most cases, identification ingested specimens level often impossible. Samples can be by molecular techniques like barcoding...
Carangid fishes are commercially important in fisheries and aquaculture. They distributed worldwide both tropical subtropical marine ecosystems. Their role food webs is often unclear since their diet cannot be easily identified by traditional gut content analysis. suspected to prey on pelagic benthic species, with clupeiform being dietary items for some though it unknown whether carangids share resources or show trophic segregation. Here, we used metabarcoding overcome challenges of...
The Neotropical freshwaters of South America host an exceptional level ichthyofaunal diversity with over 5,160 species, making it the richest continental fauna worldwide. Despite their richness, these freshwater ecosystems face severe threats from human activities, leading to significant declines in fish populations. Traditional sampling techniques, such as netting, have been fundamental ichthyology, offering insights into species richness and abundance. However, complexity stream...
Abstract Understanding the mechanisms underlying species distributions and coexistence is essential to predict prevent impacts of global change, particularly in biodiversity hotspots. However, effects biotic interactions may be challenging investigate at large spatial scales. Leveraging well-characterized Müllerian mimetic systems Neotropical butterflies, we investigated patterns mutualistic within between two tribes aposematic Nymphalid butterflies: Heliconiini (Heliconiinae) Ithomiini...
