Bartoszek K, Fuentes-Gonzalez J, Mitov V, Pienaar J, Piwczynski M, Puchalka R, et al.
Evolution
. 2023 Oct;
78(3):389-400.
PMID: 37897801
Adams and Collyer argue that contemporary multivariate (Gaussian) phylogenetic comparative methods are prone to favouring more complex models of evolution and sometimes rotation invariance can be an issue. Here we...

Sci Rep
. 2023 Sep;
13(1):16329.
PMID: 37770488
Ranges of tardigrade intraspecific and interspecific variability are not precisely defined, both in terms of morphology and genetics, rendering descriptions of new taxa a cumbersome task. This contribution enhances the...

Grabowski M, Pienaar J, Voje K, Andersson S, Fuentes-Gonzalez J, Kopperud B, et al.
Syst Biol
. 2023 May;
72(4):955-963.
PMID: 37229537
Models based on the Ornstein-Uhlenbeck process have become standard for the comparative study of adaptation. Cooper et al. (2016) have cast doubt on this practice by claiming statistical problems with...

Adams P, Eggers V, Millwood J, Sutton J, Pienaar J, Fierst J
Mol Biol Evol
. 2023 Feb;
40(3).
PMID: 36807460
Genome size has been measurable since the 1940s but we still do not understand genome size variation. Caenorhabditis nematodes show strong conservation of chromosome number but vary in genome size...

Greenspan S, Peloso P, Fuentes-Gonzalez J, Bletz M, Lyra M, Machado I, et al.
Anim Microbiome
. 2022 Dec;
4(1):69.
PMID: 36582011
Microbial diversity positively influences community resilience of the host microbiome. However, extinction risk factors such as habitat specialization, narrow environmental tolerances, and exposure to anthropogenic disturbance may homogenize host-associated microbial...

Bartoszek K, Fuentes-Gonzalez J, Mitov V, Pienaar J, Piwczynski M, Puchalka R, et al.
Syst Biol
. 2022 Dec;
72(2):275-293.
PMID: 36575879
The advent of fast computational algorithms for phylogenetic comparative methods allows for considering multiple hypotheses concerning the co-adaptation of traits and also for studying if it is possible to distinguish...

Garcia-Cabello K, Fuentes-Gonzalez J, Saleh-Subaie N, Pienaar J, Zuniga-Vega J
Biol Lett
. 2022 Oct;
18(10):20220173.
PMID: 36196554
The causes and consequences of the evolution of placentotrophy (post-fertilization nutrition of developing embryos of viviparous organisms by means of a maternal placenta) in non-mammalian vertebrates are still not fully...

J Invertebr Pathol
. 2021 Oct;
186:107677.
PMID: 34627793
Interactions between fungi and tardigrades have scarcely been described. The few studies that address such relationships suggest a primarily parasitic nature for various fungal taxa, including the infectious chytridiomycetes. The...

Front Physiol
. 2019 Dec;

PMID: 31803063
Understanding the ecological pressures that generate variation in body shape is important because body shape profoundly affects physiology and overall fitness. Using , a genus of fish that exhibits considerable...

J Vis Exp
. 2019 Jul;

PMID: 31355794
There is much to understand about the onset and progression of neurodegenerative diseases, including the underlying genes responsible. Forward genetic screening using chemical mutagens is a useful strategy for mapping...
