Comprehensive research on the community structure and spatial species diversity of demersal fish assemblages can provide not only species records but also qualitative classifications of species into ecological (functional) or zoogeographical groups for conservation and management purposes
could be a by-product of my resaerch
Correspondence analysis (CA) is attractive to community ecologists because, in contrast to methods based on principal components analysis, it allows for unimodal responses to underlying gradients, thereby providing a clear representation of ‘long’ gradients (as well as ‘short’ gradients). Detrended correspondence analysis (DCA) corrects for two artefacts in CA: the ‘arch effect’ and compression of the two extremes of the first axis
This study demonstrates the advantages of adopting quantitatively derived clusters of spatially associated species and elucidates the potential of resultant clusters as a spatially explicit framework for investigating distribution-related questions in ecology, biogeography, and conservation.
Results of plant community division are similar to previous studies in the Inner Mongolia grassland [17,35].
i cld also say this asw regardless of the methods i use
The eigenvalues of the four sorting axes were 0.8053, 0.5071, 0.2824, and 0.2235, respectively, in the order of their numerical values.
Measuring the taxonomic distance is relatively straightforward, compared with the use of more complex plant traits or phylogeny.
Based on the incidence data, this analysis was carried out by using the iNEXT package of R software
1) i can cite inext similar 2) and more importantly, uses Jaccard and Bray-Curtis
conducted using small-scale experiments spatially
why my research is gd
For species richness, the size in the R/E curve can be extrapolated to at most double or triple the minimum observed sample size

Es una herramienta que me impresiona por el hecho de que transforme los archivos de audio y video en texto de forma tan sencilla a simple vista, permitiendo así la recuperación de información conjunta con otros documentos de texto.
El ejercicio de Felipe me parece bastante solido, quizá lo que hace falta es interiorizar y comprender mejor algunos conceptos respecto a como funciona una BD como la propuesta en el video
índices
Em bancos de dados relacionais, um índice é uma estrutura de dados que melhora a velocidade de consulta de uma tabela, permitindo que o banco de dados localize registros mais rapidamente.
Quando um índice é criado em uma tabela, o banco de dados mantém uma cópia parcial dos dados da tabela na memória para permitir que as consultas sejam executadas mais rapidamente. Isso significa que, em vez de procurar em toda a tabela para encontrar um registro correspondente a um valor de pesquisa, o banco de dados pode usar o índice para localizar rapidamente o registro desejado.

Classic example of investment made on the basis of hype of tech, without evaluating it critically
