Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

The Animal Sexes as Historical Explanatory Kinds [PDF]

open access: yes, 2020
Though biologists identify individuals as ‘male’ or ‘female’ across a broad range of animal species, the particular traits exhibited by males and females can vary tremendously.

Why are some species older than others? A large-scale study of vertebrates. [PDF]

open access: yes, 2016
BACKGROUND: Strong variations are observed between and within taxonomic groups in the age of extant species and these differences can clarify factors that render species more vulnerable to extinction.

A multi‐trait evaluation of patterns and fitness consequences of breeding phenology plasticity with nocturnal warming and food restriction in a lizard

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Faced with climate warming, ectothermic species shift their breeding phenology, which is in part attributed to an acceleration of gestation or incubation in warmer environments.

Viviparity imparts a macroevolutionary signature of ecological opportunity in the body size of female Liolaemus lizards

open access: yesNature Communications
Viviparity evolved ~115 times across squamate reptiles, facilitating the colonization of cold habitats, where oviparous species are scarce or absent. Whether the ecological opportunity furnished by such colonization reconfigures phenotypic diversity and ...

Skrjabinelazia rizzoi n. sp. (Nematoda: Seuratoidea) from a Sicilian lacertid, with comments on specific and biological diversity in the genus

open access: yesParasite, 2008
Skrjabinelazia rizzoi n. sp. (Seuratoidea), from Podarcis sicula captured at Cammarata, Agrigento Province, Sicily, is distinct from the 13 known species of the genus, including Skrjabinelazia sp. Rizzo from Catania.

Primordial Germ Cell Development in the Poeciliid, Gambusia holbrooki, Reveals Shared Features Between Lecithotrophs and Matrotrophs

open access: yesFrontiers in Cell and Developmental Biology, 2022
Metazoans exhibit two modes of primordial germ cell (PGC) specification that are interspersed across taxa. However, the evolutionary link between the two modes and the reproductive strategies of lecithotrophy and matrotrophy is poorly understood.

Evidence for cryptic speciation in directly transmitted Gyrodactylid parasites of Trinidadian guppies [PDF]

open access: yes, 2015
Cryptic species complexes are common among parasites, which tend to have large populations and are subject to rapid evolution. Such complexes may arise through host-parasite co-evolution and/or host switching.

Decoding Dual Regulatory Layers: Integrating Differential Expression and Alternative Splicing Dynamics in the Evolution of Laryngeal Echolocation Across Chiropteran Lineages

open access: yesIntegrative Zoology, EarlyView.
We integrated short‐read and long‐read RNA‐seq data from cochlear tissues of echolocating and non‐echolocating bats to disentangle transcriptional and post‐transcriptional regulation. Echolocating bats showed neural‐function enrichment among differentially expressed genes, while alternatively spliced genes were linked to epigenetic regulation. Overlaps
