located anteriorly at the base of the tentacles [133]. Like other echinoderms, gametes are released in the sea water [133]. Compared to the broad information on the reproductive biology of echinoids and asteroids, less is known in holothurian...
Hybridization and Gene Structure The use of DNA hybridization has also permitted a significant glimpse of the complexity of the human genome, because it has allowed the identification of pseudogenes, nonfunctional genes that are likely relics of evolution with strong homology to functional gene, and ...
According to a survey conducted by The Xerces Society for Invertebrate Conservation, the monarch butterfly is facing a sharp population decline that could soon lead to its extinction. The monarch butterfly is considered the “king of all butterflies due to its extreme beauty, hence the name ”...
The perpetuation of mosquito-borne diseases is dependent on the compatibility of the pathogen with its invertebrate and vertebrate hosts, as dictated by each respective genome. The failure of traditional mosquito-borne disease control efforts to reduce the burden of these diseases on public health has...
Obligate symbioses with nutrient-provisioning bacteria have originated often during animal evolution and have been key to the ecological diversification of many invertebrate groups. To date, genome sequences of insect nutritional symbionts have been restricted to a related cluster within Gammaproteobacteria ...
Evolution of antimicrobial peptides (AMPs) has been shown to be driven by recurrent duplications and balancing/positive selection in response to new or altered bacterial pathogens. We use Alvinella pompejana, the most eurythermal animal known on Earth, t
Both resin-embedded cells used for TEM and cells on gold sputter-coated SEM stubs have been deposited in the Beaty Biodiversity Research Centre (Marine Invertebrate Collection) at the University of British Columbia, Vancouver, Canada. Iconotypes Figs 1A, 2A and 9A. Type locality Tidal sand-flat...
Such changes are referred to as specific or pairwise coevolution if the evolutionary responses of two species to each other have no impact on their interactions with other species. Diffuse or guild coevolution occurs when the genetic change in at least one species affects its interaction with ...
A potential empirical basis defining an emotional response can be found in the defensive and appetitive behaviors shown by a variety of species in the animal kingdom, including invertebrate animals. Living organisms tend to possess an arsenal of mechanisms for successfully dealing with challenges impose...
