TL;DR: Two improvements to the Logan model of temperature-dependent development were proposed, first eliminated a redundant parameter then incorporated an intercept parameter, thereby resolving the inability of the original model to estimate a low-temperature developmental threshold.
Abstract: We proposed two improvements to the Logan model of temperature-dependent development. We first eliminated a redundant parameter (modification 1) then incorporated an intercept parameter (modification2), thereby resolving the inability of the original model to estimate a low-temperature developmental threshold. The three model versions were compared using temperature-dependent developmental rates in six insect species (a total of 11 life stages).The original model and modification 1 produced identical curves. In 10 of the 11 cases, modification2 had the highest r2 and the least estimation bias.

TL;DR: It is concluded that read abundance is approximately quantitative within species, but between‐species comparisons can be biased by innate sequence structure, and careful consideration of sequence processing methods and community analyses are warranted when testing hypotheses using read abundance data.
Abstract: Pyrosequencing technologies have revolutionized how we describe and compare complex microbial communities. In 454 pyrosequencing data sets, the abundance of reads pertaining to taxa or phylotypes is commonly interpreted as a measure of genic or taxon abundance, useful for quantitative comparisons of community similarity. Potentially systematic biases inherent in sample processing, amplification and sequencing, however, may alter read abundance and reduce the utility of quantitative metrics. Here, we examine the relationship between read abundance and biological abundance in a sample of house dust spiked with known quantities and identities of fungi along a dilution gradient. Our results show one order of magnitude differences in read abundance among species. Precision of quantification within species along the dilution gradient varied from R 2 of 0.96‐0.54. Read-quality based processing stringency profoundly affected the abundance of one species containing long homopolymers in a read orientation-biased manner. Order-level composition of background environmental fungal communities determined from pyrosequencing data was comparable with that derived from cloning and Sanger sequencing and was not biased by read orientation. We conclude that read abundance is approximately quantitative within species, but betweenspecies comparisons can be biased by innate sequence structure. Our results showed a trade off between sequence quality stringency and quantification. Careful consideration of sequence processing methods and community analyses are warranted when testing hypotheses using read abundance data.

TL;DR: This review has integrated recent structural and functional information to create a holistic model for the peritrophic matrix, and shows how this information may generate novel technologies for use in insect pest management.
Abstract: The peritrophic matrix (PM) is a chitin and glycoprotein layer that lines the invertebrate midgut. Although structurally different, it is functionally similar to the mucous secretions of the vertebrate digestive tract. The PM is a physical barrier, protecting the midgut epithelium from abrasive food particles, digestive enzymes, and pathogens infectious per os. It is also a biochemical barrier, sequestering and, in some cases, inactivating ingested toxins. Finally, the PM compartmentalizes digestive processes, allowing for efficient nutrient acquisition and reuse of hydrolytic enzymes. The PM consists of an organized lattice of chitin fibrils held together by chitin binding proteins. Glycans fill the interstitial spaces, creating a molecular sieve, the properties of which are dependent on the immediate ion content and pH. In this review, we have integrated recent structural and functional information to create a holistic model for the PM. We also show how this information may generate novel technologies for use in insect pest management.
