The Formation and Evolution of S0 Galaxies [PDF]

open access: yes
This thesis studies the origin of local S0 galaxies and their possible links to other morphological types. To address these issues, two different approaches have been adopted: a detailed study of the stellar populations of S0s in the Fornax Cluster and a study of the Tully-Fisher Relation (TFR) of local S0s in different environments.

Cladistic Relationships and Landscape Genetics of the Endangered Indian Peacock Softshell Turtle Nilssonia hurum (Gray, 1830): Implications for Strategic Conservation Planning

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study provides the first mitogenome of the endangered Peacock Softshell Turtle (Nilssonia hurum), revealing its evolutionary relationships and moderate genetic diversity across river basins. Species distribution modeling predicts up to 85% habitat loss under future climate scenarios, alongside severe declines in functional connectivity and rising ...

Chemical evolution and galaxy formation

open access: yes, 2002
Following a review of the basic ingredients necessary for constructing models of galactic chemical evolution, with a special emphasis on the issue of stellar evolution and nucleosynthesis (which is treated in detail in Chapter 2), I continue with the basic equations that one needs to solve in order to follow the chemical evolution of a system of gas ...

The Complete Chloroplast Genome and Morphological Data Support Reinstatement of Sedum jinianum (Crassulaceae) as an Independent Species

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Phylogenetic analysis based on complete plastome data indicates that S. jinianum forms a monophyletic clade, sister to a well‐supported clade comprising four S. bulbiferum samples, supporting the reinstatement of S. jinianum as an independent species. ABSTRACT Sedum jinianum (Crassulaceae) has been treated as a synonym of S.

‘specleanr': an R package for automated flagging of environmental outliers in ecological data for modeling workflows

open access: yesEcography, Volume 2025, Issue 12, December 2025.
Developing species distribution models (SDMs) requires high‐quality species occurrence records. These records, stemming from various sources with different sampling procedures, are often archived in open‐access databases, making automated data quality checks inevitable.
