Proteins that are highly expressed and composed of amino acids that are costly to synthesize are likely to place a greater drain on an organism's energy resources than proteins that are composed of ingested amino acids or ones that are metabolically simple to produce. Silks are highly expressed proteins produced by all spiders and many insects. We compared the metabolic costs of silks spun by arthropods by calculating the amount of ATP required to produce their component amino acids. Although a… Expand
Evidence for diet effects on the composition of silk proteins produced by spiders.
TLDR
It is found that individual spiders of the same species can spin dragline silks (drawn from the spider's ampullate gland) that vary in content as well, suggesting that variation in silk composition reflects the type of prey the spiders were fed but not the total amount of prey they received. Expand
Variation in Protein Intake Induces Variation in Spider Silk Expression
TLDR
The results suggest that protein limitation induces a shift toward different silk proteins with lower glutamine and/or proline content, which is consistent with the MaSp model. Expand
Giant wood spider Nephila pilipes alters silk protein in response to prey variation
TLDR
Results of this study indicated that orb-weaving spiders can alter dragline protein in response to prey variations. Expand
Tarantulas and social spiders : a tale of sex and silk
TLDR
Previous common conceptions of dimensional morphologies were examined to see if they could adequately sex theraphosid spiders, including the species that was the subject of the silk study already described. Expand
Novel Amino Acid Assembly in the Silk Tubes of Arid-Adapted Segestriid Spiders
TLDR
The comparison of the silk tubes among the various Namibian populations shows significant differences in their amino acid assembly possibly due to habitat features, according to a multivariate statistical analysis. Expand
Relating the structure of insect silk proteins to function
TLDR
A comparative analysis of silk proteins revealed a correlation between predominant secondary structure type and more general architectural features such as length and repeat regularity: silk proteins that fold into coiled-coils and collagen helices had low molecular weights and high repeat regularities, suggesting they fold into short semi-rigid rods; β-sheet-forming silk. Expand
The common house spider, Parasteatoda tepidariorum, maintains silk gene expression on sub-optimal diet
TLDR
The results suggest that house spiders are able to maintain silk production, even in the face of a low-quality diet. Expand
Evidence of Decoupling Protein Structure from Spidroin Expression in Spider Dragline Silks
TLDR
It is suggested that a differential distribution of alanine during spinning could decouple secondary structures from spidroin expression ensuring that silks of desirable mechanical properties are consistently produced. Expand
Broad patterns of speciation are correlated with the evolution of new silk proteins in spiders but not in the lepidoptera.

TLDR
The differences in these two systems, both meeting a need to produce a large volume of protein, may reflect predictable resource availability to herbivorous Lepidoptera larvae but fluctuating resource availability for carnivorous spiders. Expand
Spider Nutrition: An Integrative Perspective
TLDR
There is a tremendous opportunity to rapidly advance the understanding of spider nutrition, given a strong foundation in the natural history, behaviour, physiology and ecology of spiders and recent advances in analytical techniques and frameworks for studying nutrition. Expand

TLDR
The comparative data and phylogenetic analyses in this review suggest that the silk-secreting systems of spiders and insects are homologous and linked to the crural gland and cuticular secretions of an onychophoran-like ancestor. Expand
The larval silk of Hypera spp. (Coleoptera: Curculionidae). A new example of the cross-β protein conformation in an insect silk
TLDR
X-ray diffraction studies on the larval cocoon silk of the weevils Hypera postica and H. rumicis indicate that it is a new example of the cross-β conformation in proteins, more complex, with a greater range of constituent amino acids, than Chrysopa (Neuroptera) silk. Expand
Insect silk glands: their types, development and function, and effects of environmental factors and morphogenetic hormones on them
Abstract Insect silk glands are ectodermal organs that evolved several times in the phylogeny from one of the following cell types: epidermal cells associated with bristle formation; sex accessoryExpand
EVOLUTIONARY SHIFTS IN THE SPECTRAL PROPERTIES OF SPIDER SILKS
TLDR
The authors' data show that all of the primitive aerial web spinners produce catching silks with a spectral peak in the ultraviolet (UV), and cladistic analysis suggests that high UV reflection is the primitive character state for silk spectral properties. Expand
INSECT ATTRACTION TO ULTRAVIOLET-REFLECTING SPIDER WEBS AND WEB DECORATIONS'
TLDR
It is proposed that UV-reflecting decorative silks, together with the UV—reflecting body surfaces of A. argentata, act as a visual display that attracts prey. Expand
The chemical composition of haemolymph in insects and some other arthropods, in relation to their phylogeny
TLDR
It is suggested that in pterygote insects a basic type of haemolymph is discernible, and that this basic type was modified in several ways and on a number of occasions during the evolution of the Insecta. Expand
THE PHYSICAL PROPERTIES OF SPIDER'S SILK AND THEIR ROLE IN THE DESIGN OF ORB-WEBS
TLDR
The physical properties of the viscid and frame silks allow them to function effectively as shock absorbers and structural elements, respectively; and allow the orb-web to function as an aerial filter with a minimum expenditure of material and energy. Expand
Phylogeny of Insect Orders
TLDR
This review is devoted to a treatment of the phylogeny of extant orders of insects and their closest relatives and to the numerous new proposals made in a thought-provoking, recent book by Boudreaux (15). Expand
The ecological and evolutionary interdependence between web architecture and web silk spun by orb web weaving spiders
TLDR
It is proposed that the evolution of alternative web building behaviours is a consequence of the general, phyletic trend to small size among araneoids, and where high energy absorption is not an exacting feature of web design, web architecture should not be tightly constrained to the orb. Expand
Spider feeding behaviour optimises dietary essential amino acid composition
TLDR
It is shown that free-living wolf spiders will tend to prey on three species in proportions which optimise the proportions of the essential amino acids they provide in the diet. Expand
