Sexual selection can have a significant influence on intraspecific phenotypic diversity (Gray & McKinnon, 2007).One of the main components of sexual selection is mate choice, exerted more commonly by females (Andersson & Simmons, 2006).Many theoretical models attempt to explain how female preference can drive sexual selection and how it can arise and be maintained (reviewed in Andersson and ...

answer choices. Sharp reduction in population size due to an environmental disaster, often results in loss of variation. When individuals survive and reproduce at a higher rate than others in the same population. Process by which populations have become adapted to their environment over time.

Significant levels of phenotypic plasticity were evident in response to changes in SIC in normal environmental conditions. Maximum foraging efficiency occurred at relatively low SIC, peaking at 6.1% and decreasing with higher SIC. The ‘natural experiment’ uncoupled efficiency levels from SIC variations.

Why does the fitness of a phenotype depend on frequency-dependent selection? A) Because frequency-dependent selection acts against extreme phenotypes. B) Because the least number of alleles are at that locus. C) Because selection favors the least common phenotype. D) Because sexual selection produces dimorphism.

Disruptive selection acts to push the distribution of a trait towards its extremes 28. In this case, there was an association between reproductive output and both low and high levels of aggression.

RL models are increasingly used to measure processes hypothesized to be disrupted in psychiatric disorders. These models are on the cusp of clinical application ; however, computationally derived measures must first show acceptable psychometric properties. Although conditions for acceptable validity have been established, whether measures of model-based planning and other RL measures reliably measure latent constructs in real-world empirical samples has been unclear.

example of disruptive selection in human evolution. Despite its rarity, however, disruptive selection may be very important for the emergence of species. After suitable time, disruptive selection can lead to bimodal distributions that might eventually lead to different species. [Insert Figure 13.3 about here] The Effect of Natural Selection

Freeze-thawing is one of the physical agents which can be used in multiple cycles to disrupt the cellular membrane by intracellular ice crystals without using chemical agents. It has been shown that freeze-thaw cycles result in minor alterations in tissue architecture and do not change the mechanical properties of ECM.

How are fitness and adaptation important to natural selection because one?

Adaptation by natural selection has been central to biology ever since Darwin presented the idea more than 150 years ago. When coupled to theories of mutation and inheritance, it explains how organisms become fit to their environments.

How is the thickness of silk sheets measured?

It is measured by counting the number of threads contained in one square inch of fabric or one square centimeter, including both the length (warp) and width (weft) threads. The thread count is the number of threads counted along two sides (up and across) of the square inch, added together.

Why does silk thickness matter in spiders cause?

Our results suggest that changes in silk protein structures do not affect silk colour via variation in the silk's refractivity or birefringence. We thus expect the most likely cause of the yellow or white coloration observed in T. plumipes silk to be pigment deposition, as has been speculated for Trichonephila clavipes [ 6 , 37 ].

Why does silk thickness matter in spiders grow?

Spider silk is a protein fibre spun by spiders. Spiders use their silk to make webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey. They can also use their silk to suspend themselves, to float through the air, or to glide away from predators. Most spiders vary the thickness and stickiness of their silk for different uses. In some cases, spiders may even use silk as a source of food. While ...

Why does silk thickness matter in spiders images?

Why MA silk should vary in colour among and between species and individuals is thus unknown. Nevertheless, there are some potential explanations. First, the shape and thickness of the skin, the appearance of cracks or microfibrils, twisting and accumulation of particulate debris may affect some of the silk's optical properties [ 26, 35, 36 ].

Why does silk thickness matter in spiders like?

One may be wondering why the spider silk in contrast to the silk of the silkworm, is not of great commercial importance. One reason lies in the varying thickness of spider thread. Also it is more difficult to work with, and, because it does not stand up well in the weaving process, it lacks the luster of insect silk.

Why does silk thickness matter in spiders video?

Spiders make many kinds of silk. The best known is dragline silk which the spider uses in web construction and also for "hanging around". Dragline silk consists of proteins called spidroins. These are made in the spider's silk glands as a thick paste that is drawn into fibers during spinning. Once spun, the silk is strong and very tough.
