متن کاملHabitat, Life History, and Behavioral Adaptations of Aquatic Insects
The observed patterns of distribution and abundance of aquatic insects indicate successful adaptations to a wide variety of habitats. To demonstrate how organisms adapt to particular niches of the freshwater community, examples of species using certain environments are presented in this chapter and the life cycle is used as a framework for describing diverse modes of coping with environmental c...
متن کاملAquatic organisms as amber inclusions and examples from a modern swamp forest.
To find aquatic organisms in tree resin may seem to be highly unlikely, but the fossil record provides numerous amber-preserved limnetic arthropods (e.g., water beetles, water striders, and crustaceans) and microorganisms (e.g., bacteria, algae, ciliates, testate amoebae, and rotifers). Here we explain the frequently discussed process of embedding aquatic organisms in tree resin based on field ...
متن کاملBiomechanics and energetics in aquatic and semiaquatic mammals: platypus to whale.
A variety of mammalian lineages have secondarily invaded the water. To locomote and thermoregulate in the aqueous medium, mammals developed a range of morphological, physiological, and behavioral adaptations. A distinct difference in the suite of adaptations, which affects energetics, is apparent between semiaquatic and fully aquatic mammals. Semiaquatic mammals swim by paddling, which is ineff...
متن کاملSkin of the Cretaceous mosasaur Plotosaurus: implications for aquatic adaptations in giant marine reptiles.
The physical nature of water and the environment it presents to an organism have long been recognized as important constraints on aquatic adaptation and evolution. Little is known about the dermal cover of mosasauroids (a group of secondarily aquatic reptiles that occupied a wide array of predatory niches in the Cretaceous marine ecosystems 92-65 Myr ago), a lack of information that has hindere...
