, 2022 The internal evolution of bars promotes the vertical movement of stars that eventually will form boxy/peanut structures. Most attention has been paid to this bar-related galaxy component in the last years, mostly due to the discovery of a box/peanut in our own Milky-Way.

Integrative Zoology, EarlyView.This study revealed the basic structures of gut mycobiota of three wild Rhinopithecus species. The gut mycobiota of Rhinopithecus showed close connection with their feeding habits, and there were associations between gut mycobiota and the host's living environments.

Relatively young thick discs in low-mass star-forming late-type galaxies [PDF]
arXivWe aim to trace the evolution of eight edge-on star-forming disc galaxies through the analysis of stellar population properties of their thin and thick discs. These galaxies have relatively low stellar masses (4 $\times$ 10$^9$ to 6 $\times$ 10$^{10}$ $M_{\odot}$).

Spatial Dynamics and Lifespan of Adult Cicadas After Fire and Logging: A Radiotracking Study
Integrative Zoology, EarlyView.This study investigates the effects of wildfire and post‐fire salvage logging on the survival, spatial behavior, and habitat selection of Lyristes plebejus cicadas in Mediterranean pine forests. A total of 63 cicadas were captured, tagged with radio transmitters, and released in three disturbance contexts: burnt‐logged, burnt‐unlogged, and unburnt ...

Formation and evolution of bars in disc galaxies
, 2002 I follow a bar from its formation, via its evolution, to its destruction and, perhaps, regeneration. I discuss the main features at each stage and particularly the role of the halo. Bars can form even in sub-maximum discs. In fact, such bars can be stronger than bars which have grown in maximum discs.

Persistence of Ancestral KhoeSan Mitochondrial Patterns in Contemporary South African Populations
Annals of Human Genetics, EarlyView.Abstract Introduction Southern Africa has been inhabited by hunter‐gatherers for at least 20,000 years and has received diverse immigration flows in the last 2000 years. The original inhabitants have interacted with the pastoralist migrants from Eastern Africa (∼2000 ybp), followed by the southern Bantu migration arriving some 1000 ybp, and more ...

Australian Journal of Politics &History, EarlyView.“Professional politicians” have been lamented for their perceived negative impact on representative democracy. However, the concept of “political professionalisation” is deployed inconsistently, making these claims difficult to assess. This article develops a framework to measure professionalisation across two dimensions: career professionalisation ...
