Molecular Ecology is an international journal for research using molecular genetic techniques to address questions in ecology, evolution, behavior and conservation
- 4. 4. 2: Phylogeny and Cladistics - Biology LibreTexts
Speciation occurs by splits of one species into two, never more than two at a time, and at one point in time This is a simplification but is accepted by most biologists Traits change enough over time to be considered to be in a different state It is also assumed that one can identify the direction of change for an adaptation
- Solved 3. Examine the partial phylogenies of two major . . .
Which clade exhibits the most conservative evolutionary trends within the last 15 million years? (Globorotaliid clade) (Globigerinid clade) в what is the rate of speciation in the Globortalid clade over the past 5 million years (; new species million years)?
- Microreserves are an important tool for amphibian conservation
We used amphibian range maps from AmphibiaWeb and the International Union for the Conservation of Nature, or IUCN (available for 7094 species–over 83% of named amphibian species) 19,26,37 For mammals and reptiles, we used ranges from the IUCN and the Global Assessment of Reptile Distributions group (10,811 reptiles and 5,850 mammals) 26,38,73,74
- Amniotes Flashcards - Quizlet
Amniotes don't dehydrate in air as quickly as amphibians because their tough, dry skin have cells that are filled with keratin and lipids, substances that are relatively impermeable to water The eggs of modern reptiles and birds have four specialized (blank) and a hard leathery (blank)
- Motilin Comparative Study: Structure, Distribution, Receptors . . .
Motilin, produced in endocrine cells in the mucosa of the upper intestine, is an important regulator of gastrointestinal (GI) motility and mediates the phase III of interdigestive migrating motor complex (MMC) in the stomach of humans, dogs and house musk shrews through the specific motilin receptor …
- UC Berkeley - eScholarship
The species is a human commen-sal, an attribute that allows it to easily disperse, including over previously impermeable saltwater barriers to colonize islands, and it possesses the ‘opti-mal range-expansion phenotype’ associated with highly dispersive bufonid species with large distributions [2] The species recently invaded Borneo [3],
