Three-dimensional digital analysis of musteloid masticatory muscle architecture
1 INTRODUCTION The anatomy of skeletal muscle is intrinsically related to its function at both the gross and architectural levels (Gans & Bock, 1965; Granatosky & Ross, 2020; Schumacher, 1961; Turnbull, 1970). Muscle bodies are comprised of bundles of fascicles, which are themselves bundles of muscle fibers (multinucleated cells) that contain serially arranged sarcomeres, the unit of the muscle that provides contraction (Gans, 1982; Gans & Bock, 1965; Lieber, 1986; Powell et al., 1984).
Beakiation: how a novel parrot gait expands the locomotor repertoire of living birds
A central tenet of functional morphology—particularly within the context of palaeontological reconstructions of extinct behaviours—is that specific morphological traits or configurations are indicative of an animal's behavioural repertoire [1].
Ecological correlates of three‐dimensional muscle architecture within the dietarily diverse Strepsirrhini
1 INTRODUCTION Muscular anatomy, on both the macro- and micro-scale, is intrinsically related to muscle function (Gans & Bock, 1965; Schumacher, 1961; Turnbull, 1970). As such, quantifying skeletal muscle within a comparative context represents a critical means of bridging the divide between form and function (Anapol & Barry, 1996; Gans, 1982; Hartstone-Rose et al., 2018; Kikuchi, 2010; Lieber & Fridén, 2000; Marchi et al., 2018; Payne et al., 2006).
Skeletal age during hurricane impacts fluctuating asymmetry in Cayo Santiago rhesus macaques
1 INTRODUCTION Fluctuating asymmetry (FA)—defined as random deviations from symmetry in traits that are otherwise bilaterally symmetrical—has been repeatedly demonstrated to reflect a morphological proxy for the frequency and/or magnitude of stress events experienced by an individual (Badyaev et al., 2000; Lens et al., 1999; Polak, 2003; Sherman et al., 2009; Weller & Ganzhorn, 2004).
Animals | Free Full-Text | Patterns and Factors Influencing Parrot (Order: Psittaciformes) Success in Establishing Thriving Naturalized Populations within the Contiguous United States
Abstract : Simple Summary Parrots (Order: Psittaciformes) are an ancient arboreal lineage with a long history as companion animals for humans. Since at least the 1960s, released parrots have become established in non-native ranges globally. The method of their introduction is almost certainly a direct result of the pet trade through either accidental or intentional releases.
Behavioral correlates of fascicular organization: The confluence of muscle architectural anatomy and function
1 INTRODUCTION Skeletal muscle is a complex and hierarchically organized material responsible for generating the forces that power movements of the body.
Overcoming a ‘forbidden phenotype’: the parrot's head supports, propels and powers tripedal locomotion
You have accessResearch articles Abstract No vertebrate, living or extinct, is known to have possessed an odd number of limbs. Despite this ‘forbidden phenotype’, gaits that use odd numbers of limbs (e.g. tripedalism or pentapedalism) have evolved in both avian and mammalian lineages. Tripedal locomotion is commonly employed by parrots during climbing, who use their beaks as an additional support.
Total Eclipse of the Zoo: Animal Behavior during a Total Solar Eclipse
1. Introduction The astronomical phenomenon of a total solar eclipse has long been of interest to animal behaviorists (e.g., [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]) and indeed to the broader public and scientific community. Due to the rare nature of this event—a total eclipse of the sun by the moon occurs in the same place only once in a ~375 year timespan [ 9 ]—this phenomenon is novel to those animals that experience its effects and, consequently, may induce anomalous behaviors.
Add ‘Pseudo Thumb’ to the Aye-Aye Lemur’s Bizarre Anatomy
Trilobites Hiding in the weird creature’s palm was something that scientists had missed. Something unexpected was hiding amid the gangly fingers of the aye-aye lemur. Madagascar’s aye-aye lemur is an endearing aberration of an animal. It has enormous ears, a bushy tail, mammary glands between its legs and white hairs that bristle when it’s agitated. Above a vampiric nose and mouth of incisors that never stop growing, candy-corn-colored eyes glow like full moons.
