, 2018 Selection to prevent interspecific mating can cause an increase or a decrease in self pollination in sympatric populations. Characterizing geographic variation in self and interspecific incompatibilities within a species can reveal if and how the ...

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy
The Anatomical Record, EarlyView.Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Interspecific Competition and Population Control in Freshwater Fish
, 1956 Interspecific competition is defined as the demand of more than one organism for the same resource of the environment in excess of immediate supply. When two species are "competing for a niche" the term competition has been used to include phenomena ...

The Anatomical Record, EarlyView.Abstract In a large sample of adult crab‐eating macaques, we quantified sexual dimorphism in size, shape, and covariance across the whole skull and among anatomical regions of the cranium and mandible. All regions showed significant mean sex differences, but the magnitude of size and shape dimorphism varied substantially.

Interspecific interactions and premating reproductive isolation
, 2019 Interspecific interactions have several evolutionary consequences: for example, two species may compete, hybridize, or behave aggressively towards each other, or there may be predator–prey interactions.

The Anatomical Record, EarlyView.Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Interspecific interaction network of mites associated with mango trees
Experimental and Applied AcarologyAbstract Direct and indirect ecological interactions, environmental factors, and the phenology of host plants can shape the way mites interact. These relationships interfere with species occurrence and consequently alter the structure and stability of the intraplant community.

Clade‐wide morphological and functional variation of the sauropsid columella
The Anatomical Record, EarlyView.Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Maize/Peanut Intercropping Affects Legume Nodulation in Semi-Arid Conditions
AgronomyMaize/peanut intercropping is practiced widely to increase land productivity and considered a sustainable way for using and saving resources through peanut’s complementary N source via biological N2 fixation. Our study aims to understand how maize/peanut

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes
The Anatomical Record, EarlyView.Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.
