Abstract:

Knowing biological aspects of the families Falconidae and Strigidae as vocalization is relevant, since we could use this aspect as a basis to group species and evaluate their similarity. In this sense, the vocalizations of 11 species belonging to the Falconidae and Strigidae families were characterized, through the download of 53 audios per species from the Xeno Canto public access database. The variables considered in this study were: frequency, amplitude, duration, number of frequency peaks, crest factor, mean amplitude envelope and index of acoustic complexity. Once the vocalizations were c

Abstract:

Community similarity is often assessed through similarities in species occurrences and abundances (i.e., compositional similarity) or through the distribution of species interactions (i.e., interaction similarity). Unfortunately, the joint empirical evaluation of both is still a challenge. Here, we analyze community similarity in ecological systems in order to evaluate the extent to which indices based exclusively on species composition differ from those that incorporate species interactions. Borrowing tools from graph theory, we compared the classic Jaccard index with the graph edit distance

Abstract:

The Lactobacillus species by 16S Amplified Ribosomal DNA Restriction Analysis (16S-ARDRA) was identified. Lactobacilli are bacteria often found in foodstuffs of both animal and vegetable origins. On one hand, they play an important role in the food spoilage and, on the other hand, they are used as starter cultures in food fermentation processes. The species-specific identification by traditional biochemical methods is time consuming and not always fully effective. Therefore, more efficient techniques are searched for.

Abstract:

Abstract Similarity measures are among the most intuitive and common measures for comparing two or more sites, or samples, with respect to their species overlap. A restriction of similarity measures is that they are limited to pairwise comparisons even in a multiple-site study. This work presents a multiple-site similarity measure that makes use of information on species shared by more than two sites and avoids the problem of covariance between pairwise similarities in a multiple-site study. Further, we show that our multiple-site similarity measure is related to β -diversity measures such as

Abstract:

Traditionally, textual data storage and retrieval systems were designed primarily for human reading, mainly relying on paper records. However, as information technology has advanced, computerized searches have become common. However, Boolean logic-based data retrieval systems often struggle to handle data's diversity and richness effectively. These systems rely on strict matching rules, which can lead to either too few or too many results. For example, when searching for plant species descriptions, a query like "circle" AND "ellipse" may exclude relevant records that describe these traits usin

In the Origin of Species, Charles R. Darwin [Darwin C (1859) On the Origin of Species] proposed that the struggle for existence must be most intense among closely related species by means of their functional similarity. It has been hypothesized that this similarity, which results in resource competition, is the driver of the evolution of antagonism among bacteria. Consequently, antagonism should mostly be prevalent among phylogenetically and metabolically similar species. We tested the hypothesis by screening for antagonism among all possible pairwise interactions between 67 bacterial species

Abstract:

Acoustic recordings of birds have been used by conservationists and ecologists to determine the population density and bio- diversity of bird species in a region. However, it is hard to analyze and visualize the presence/absence of a specific bird species by aurally hearing these recordings even by an expert bird song specialist. In this paper, we present a computational tool to cluster and recognize bird species based on their sounds and visualize relationships of within-species and between-species sounds based on their similarity measures. The tool has been evaluated on two datasets of varyi

Abstract:

The cellular fatty acid composition of about 160 strains of Bacillus, lactic acid bacteria, Enterobacteriaceae, and Staphylococcus was analyzed in order to identify foodborne bacteria. In a first step, the reproducibility of the procedure, from the bacterial growth to the extraction and analysis conditions, was evaluated. The stability of fatty acid composition under controlled conditions was confirmed through high similarity levels (So ≥ 94). Secondly, intraspecies similarity was estimated. The existence of low values (So ≤ 79) was demonstrated within each of the four groups of strains invest

Abstract:

This study aims to characterize and compare three <em>Cerrado </em>areas (one <em>cerradão </em>and two <em>cerrado sensu stricto </em>areas) in Patrânia, São Paulo state, southeastern Brazil, concerning the floristic composition. In total, 250 taxa were found belonging to four species of pteridophytes, one species of an exotic gymnosperm and 243 species of angiosperms. Differences in species number and proportion of the woody and herbaceous components were observed among the three <em>Cerrado </em>areas. The similarity analysis revealed that the <em>cerradão </em>seems quite peculiar, showing

Abstract:

<b>Background and aims</b> – Biotic homogenization, i.e.increasing similarity between communities through time, is promoted by alien species exchange. Biotic homogenization can occur at several spatial scales. Urban environments, with their deep and convergent anthropogenic transformation worldwide, are nodes of intense species exchange. Our objective was to explore biotic homogenization at a global scale, and to achieve this goal we analyzed the effect of alien species on homogenization of two urban floras at an intercontinental scale. <b>Methods</b> – We sampled the spontaneous flora of two

Abstract:

The taxonomic status of the species Lactobacillus durianis and Lactobacillus vaccinostercus is briefly summarized and experimental evidence concerning their similarity is presented. Highly similar 16S rRNA gene sequences (99.8 % similarity over 1523 bp), partial recA gene sequences (99.5 % similarity over 600 bp) and partial hsp60 gene sequences (99.1 % similarity over 924 bp) suggest that the two species are closely related. Moreover, a high DNA–DNA binding level (87 %) and similar genomic DNA G+C contents (41–44 mol% for both species) as well as similar biochemical characteristics support th

Abstract:

The selection of model species tends to involve two typically unstated assumptions, namely: (1) that the similarity between species decreases steadily with phylogenetic distance, and (2) that similarities are greater at lower levels of biological organization. The first assumption holds on average, but species similarities tend to decrease with the square root of divergence time, rather than linearly, and lineages with short generation times (which includes most model species) tend to diverge faster than average, making the decrease in similarity non-monotonic. The second assumption is more di

Abstract:

Faunal homogenization and differentiation occur when geographic regions show increased or decreased, respectively, similarity to each other in species composition owing to introductions and extinctions or extirpations. I used species presenceabsence data for "native" (i.e., estimated species compositions before European settlement) and "total" (i.e., including nonnative fishes and extinctions) faunas to examine faunal similarity of freshwater fishes among aquatic ecoregions of British Columbia and among Canadian provinces and territories. British Columbia ecoregions showed faunal differentiat
