Coryphellina rubrolineata (Gastropoda: Nudibranchia: Flabellinidae) was believed to be a widespread tropical species demonstrating high diversity in external and internal morphological traits. In this paper, we perform an integrative analysis of the...
Previous mesocosm experiments with the epizoon of Dreissena polymorpha revealed that the communities of Rotifera and Crustacea were much more abundant and had higher species richness than epizoon of Unio tumidus in nature. These differences could be...
Small-scale fisheries (SSFs) in the Mediterranean and Black seas play a significant social and economic role, representing 84% of the fishing fleet (70,000 vessels), 26% of total revenue (USD 633 million) and 60% of total employment (150,000 people),...
The taxonomy and distribution of Orientogomphus minor (Laidlaw, 1931) were investigated in Thailand. Gomphid nymphs were collected from 28 sampling sites in streams in eastern, western, and southern Thailand. The nymph of O. minor is described for th...
Biogenic habitats often form hot spots of biodiversity. However, the role of epibiosis and the ‘habitat cascades’ phenomenon in enhancing structural heterogeneity and biodiversity in biogenic habitats in remote and difficult-to-access are...
The Qinghai–Tibet Plateau includes the Himalayas and Hengduan Mountains and is well known for its rich biodiversity. Evolutionary radiation is one of the main ways by which plants diversify in mountains, particularly the Qinghai–Tibet Pla...
The association of endophytic fungi with the host plant is called a symbiotic relationship. Studies of the endophytic fungi from tea have been reported in numerous documents, but researchers still largely focus on tea endophytic fungi as they have ab...
Romanian territory represents a key point in the dispersal of domestic pigs into Europe, due to its geographical position. Our study gathers a high number of samples from different archaeological sites on Romanian territory in order to establish a mo...
Ethnobotany has been, for too long, a descriptive discipline. However, ethnobotanists are increasingly calling for a paradigm shift towards the formulation of unifying theories and hypothesis-driven research in ethnobotany. Here, we formulated a theo...
Caseins play an important role in determining the technological properties and quantitative characteristics of camel milk. To date, only a few studies on the genetic polymorphism of casein genes have been reported in the camel populations of Kazakhst...
Lichens collected worldwide for centuries have resulted in millions of specimens deposited in herbaria that offer the potential to assess species boundaries, phenotypic diversification, ecology, and distribution. The application of molecular approach...
Rhodolith beds are biogenic benthic habitats mainly formed by unattached, non-geniculate coralline algae, which can be inhabited by many associated species. The Brazilian continental shelf encompasses the largest continuous rhodolith bed in the world...
Extra-pair copulation (EPC) occurred in most socially monogamous bird species. The mechanisms leading to the frequent occurrence of extra-pair offspring (EPO, EPY) in socially monogamous couples, as well as the ‘function’ of EPC, are the...
Diversity is instituting the Best Paper Awards to recognize the outstanding papers published in the journal [...]
Although the number of known tardigrade taxa in Mexico has increased significantly in the last ten years, the knowledge of their diversity faces challenges, as more than half of the Mexican territory has no records of this phylum. Thus, we developed...
Runs of homozygosity (ROH) are contiguous stretches of homozygous genotypes that are passed from parents to their offspring. ROHs are suitable for determining population history, inbreeding rates, and the genetic relationships between individuals in...
Experimental results from a multi-year exclosure study (2009–2015) demonstrate strong effects of geese on plant cover and species diversity in an urban, restored tidal freshwater wetland. Access by geese inhibited plant establishment and suppre...
The study of banana herbs and fruits is rarely conducted using multidisciplinary approaches. However, a multidisciplinary approach could be useful for gaining information on many aspects, including remote sensing, biodiversity and biogeography, owing...
A checklist of arrenurids of Mexico is presented, including three new records from the Yucatan Peninsula. We provide updated descriptions of Arrenurus mexicanus, A. (Megaluracarus) colitus, and A. (Megaluracarus) marshalli. Additionally, four new spe...
Metaphire remanens sp. nov. is widely distributed throughout Hunan Province, China. We sequenced the mitochondrial DNA to investigate its population genetic structure and genetic diversity, including cytochrome c oxidase subunit I, cytochrome c oxida...
Geographic isolation, a relatively low species richness and high endemism make oceanic islands excellent natural laboratories for ecological and evolutionary studies. Here we used Baited Remote Underwater stereo-Video systems (stereo-BRUVS) to invest...
Generally, the high levels of biodiversity found in natural ecosystems have positive effects on ecosystem functions (EFs), though the intensity and direction of such effects can vary. This is associated with the impacts of other EF-driving factors. I...
Biological imaging is an essential tool to visualise and obtain reference data. In this context, the programme ImageJ has been widely used in many disciplines to determine the surface areas of planar biological samples in marine and aquatic experimen...
Estimation of biodiversity patterns in poorly known areas is hampered by data availability and biased collecting efforts. To overcome the former, patterns can be estimated at higher taxonomic levels and larger spatial units. To deal with the latter,...
