Global Ecology and Conservation, 2023 Studying spatiotemporal changes in beta diversity and its drivers yields meaningful information to promote nature conservation. In this study, we surveyed tree and shrub species diversity in 107 historical plots in the southeastern Qinghai-Tibet Plateau.

Of beta diversity, variance, evenness, and dissimilarity [PDF]
Ecology and Evolution, 2017 AbstractThe amount of variation in species composition among sampling units or beta diversity has become a primary tool for connecting the spatial structure of species assemblages to ecological processes. Many different measures of beta diversity have been developed.

Empirical evaluations between beta-diversity, environmental heterogeneity, and spatial extent among multiple taxonomic groups [PDF]
Acta Limnologica BrasiliensiaAim Beta diversity is expected to increase due to environmental heterogeneity and spatial extent. However, it remains unknown whether the response of beta diversity to these variables is consistent among different taxonomic groups. I investigated whether

PLoS ONE, 2012 Biodiversity assessment of tropical taxa is hampered by their tremendous richness, which leads to large numbers of singletons and incomplete inventories in survey studies.

Frontiers in Ecology and Evolution, 2023 The emergence of metacommunity theory has significantly contributed to our understanding of the drivers of community assembly and biome variation. The Network Location Hypothesis (NPH) posits that tributary communities situated at the source regions of a

Species packing and the latitudinal gradient in beta-diversity [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2020 Abstract The decline in species richness at higher latitudes is among the most fundamental patterns in ecology. Whether changes in species composition across space (beta-diversity) contribute to this gradient of overall species richness (gamma-diversity) remains hotly debated.

Personalized Zebrafish Models for Fusion‐Positive Pediatric Sarcomas
Pediatric Blood &Cancer, EarlyView.ABSTRACT Clinical sequencing efforts have revolutionized our approaches to categorizing pediatric cancers in real time. This has dramatically improved our ability to profile pediatric tumors, identify actionable vulnerabilities, and influence clinical care.

An operational, additive framework for species diversity partitioning and beta‐diversity analysis [PDF]
Journal of Ecology, 2007 Summary An important goal of community ecology is the assessment of factors that are likely to influence the spatio‐temporal distribution of species assemblages and diversity. Surprisingly, most statistical methods devoted to this have remained poorly interconnected, as well as poorly connected with the popular metrics of diversity estimation.

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).

Global Ecology and ConservationBeta diversity is often assessed at different spatial and temporal scales and, consequently, has been defined in multiple ways. Here, we define four unique aspects of beta diversity that encompass the diverse applications of this concept in ecology and ...
