Seleção de variáveis categóricas utilizando análise de correspondência e análise procrustes

Acta Scientiarum: Technology, 1999
A análise de correspondência é uma técnica da análise multivariada (em particular, um método de análise fatorial para variáveis categóricas) que permite obter uma representação gráfica através da distribuição dos scores das categorias de linhas e/ou ...

3D pollination biology using micro‐computed tomography and geometric morphometrics in Theobroma cacao

Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023
Abstract Premise Imaging technologies that capture three‐dimensional (3D) variation in floral morphology at micro‐ and nano‐resolutions are increasingly accessible. In herkogamous flowers, such as those of Theobroma cacao, structural barriers between anthers and stigmas represent bottlenecks that restrict pollinator size and access to reproductive ...

Constructing a multiple‐part morphospace using a multiblock method

Methods in Ecology and Evolution, Volume 14, Issue 1, Page 65-76, January 2023., 2023
Abstract Popular current methods for quantifying variation in biological shape are well‐suited to analyses of isolated parts (e.g. the same bone from the skeletons of many individuals). An analytical challenge exists for quantifying variation between the shapes of multiple‐part objects where each part has a different position, rotation or scale (e.g ...

A monogenean parasite reveals the widespread translocation of the African clawed frog in its native range

Journal of Applied Ecology, Volume 59, Issue 11, Page 2670-2687, November 2022., 2022
Data from cointroduced, host‐specific parasites, as tags for translocation, can add value to investigations in invasion biology and conservation. A better understanding of the translocation history and resulting genetic mixing of host and parasite lineages in the native range can shed light on the genetic make‐up of parasite assemblages cointroduced to

The skin microbiota in equine pastern dermatitis: a case‐control study of horses in Switzerland

Veterinary Dermatology, Volume 32, Issue 6, Page 646-e172, December 2021., 2021
Background – Equine pastern dermatitis (EPD), a multifactorial syndrome, manifests as skin lesions of variable severity in the pastern area. Despite the widespread use of antibacterial therapy for treating this condition, little is known about the contributing bacteria.
