Behavioural Acoustics and Sensory Ecology Biosonar: adaptive signal design and echo evolution; Bat flight and sonar-based navigation; Spatiotemporal use
As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans, and they are uniquely attuned in these fellow mammals. Living among seagrasses and algae, the seahorse adopts an upright posture and moves by fluttering its pectoral fins, and the closely related pipefish moves by rippling its elongated dorsal fin. The sensory inputs that a parasite employs to identify and approach a potential host are known as "host cues". Such cues can include, for example, vibration, exhaled carbon dioxide, skin odours, visual and heat signatures, and moisture. Bees are a monophyletic lineage within the superfamily Apoidea and are presently considered a clade, called Anthophila. There are over 16,000 known species of bees in seven recognized biological families. They are found on every continent… In this new assessment of the empirical evidence, an alternative to the standard model is proposed: group selection is the strong binding force in eusocial evolution; individual selection, the strong dissolutive force; and kin selection… Fossil sites from Brazil have yielded specimens of spinosaurid theropods, among which the most informative include the cranial remains of Irritator, Angaturama, and Oxalaia. In this work some of their craniodental features are reinterpreted… How and why animals lose eyesight during adaptation to the dark and food-limited cave environment has puzzled biologists since the time of Darwin. More recently, several different adaptive hypotheses have been proposed to explain eye…
Enago's expert academic, scientific editing and journal editing team comprises of native English speakers who are PhD/Master's holders and all are subject-area specialists. These results imply that young turtles have a `magnetic map' in which regional magnetic fields function as navigational markers and elicit changes in swimming direction at appropriate geographic locations (Lohmann et al., 2007). A lipid-binding protein mediates both attraction and hypersensitivity to a beetle sex pheromone in a specific type of nematode-insect relationship known as necromeny. However, traditionally fish are rendered paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Many fish also have chemoreceptors that are responsible for extraordinary senses of taste and smell. Although they have ears, many fish may not hear very well. As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans, and they are uniquely attuned in these fellow mammals. Living among seagrasses and algae, the seahorse adopts an upright posture and moves by fluttering its pectoral fins, and the closely related pipefish moves by rippling its elongated dorsal fin.
Convergent evolution in humans includes blue eye colour and light skin colour. When humans migrated out of Africa, they moved to more northern latitudes with less intense sunlight.

Grant (Elsevier, 2001).pdf Behavioral ecology is the study of the ecological and evolutionary basis for animal behavior. Primarily concerned with ultimate (evolutionary) consequences, researchers aim to identify phylogenetic contingencies within behavior (i.e., to… At the behavioral level, we first investigated the commonalities and specificities of metacognition across sensory domains including touch, a sensory modality that has been neglected so far.
