The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

open access: yesThe Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

How might epigenetics contribute to ecological speciation?

open access: yesCurrent Zoology, 2013
Speciation research has seen a renewed interest in ecological speciation, which emphasises divergent ecological selection leading to the evolution of reproductive isolation.

Tracheal chambers as a key innovation for high‐frequency emission in bat echolocation

open access: yesThe Anatomical Record, EarlyView.
Abstract Key innovations are pivotal for biodiversity and facilitating evolutionary success, enabling organisms' adaptation to various ecological niches through the diversification of phenotypic traits. In mammals, notable adaptations include evolving hypsodonty for grazing on grasses and, for bats, evolving echolocation and wing acquisition.

Quantitative Partitioning of Photoautotrophic and Photoheterotrophic Contributions During Mixotrophic Growth of Scenedesmus obliquus

open access: yesBiotechnology and Bioengineering, EarlyView.
Carbon and oxygen fluxes during photoautotrophic, photoheterotrophic and mixotrophic growth of Scenedesmus obliquus. ABSTRACT Mixotrophic growth of microalgae involves the simultaneous assimilation of inorganic and organic carbon sources, but the quantitative contributions of photoautotrophic and photoheterotrophic metabolisms remain poorly resolved ...

Spatiotemporal Diversification of Global Junipers: Traces of Niche Conservatism and Trait‐Dependent Diversification

open access: yesEcology and Evolution
Speciation rates differ globally across phylogenies and regions, and the complexity of the speciation process makes it difficult to fully understand these variations.

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 ...

Review of the fauna associated with wild and farmed mussels and oysters in the Mediterranean

open access: yesBiological Reviews, EarlyView.
ABSTRACT Mussels and oysters are important ecosystem engineers which modify the physical and chemical characteristics of the environment and create habitats that support highly diverse associated communities. In the Mediterranean Sea, the native Mediterranean mussel Mytilus galloprovincialis and the European flat oyster Ostrea edulis, together the ...

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

How developmental stressors affect mitochondrial respiratory function: a systematic review and meta‐analysis

open access: yesBiological Reviews, EarlyView.
ABSTRACT The environmental conditions organisms experience during early development can have powerful and sustained effects on morphology, physiology, behaviour, and performance. Such developmental effects can influence reproductive success, survival, and life‐history strategies and can be transmitted across generations (i.e.
