Undersampling bias: the null hypothesis for singleton species in tropical arthropod surveys.
TLDR
The lognormal distribution deserves greater consideration as a richness estimator when undersampling bias is severe, and should be the default null hypothesis for singleton frequencies.
A revision of Herennia (Araneae : Nephilidae : Nephilinae), the Australasian 'coin spiders'
TLDR
To explain the peculiar male sexual behaviour known in Herennia and Nephilengys, three specific hypotheses based on morphological and behavioural data are proposed: (1) broken embolic conductors function as mating plugs; (2) bulb severance following mutilation is advantageous for the male to avoid hemolymph leakage; and (3) the eunuch protects his parental investment by fighting off rival males.
Phylogenetic systematics of the Gondwanan nephilid spider lineage Clitaetrinae (Araneae, Nephilidae)
TLDR
A species‐level phylogenetic analysis of 32 taxa results in eight most parsimonious cladograms and places Clitaetra as sister to the clade (Herennia+ (Nephilengys+Nephila), which contains the orb‐weaving spider family Nephilidae Simon, but not Deliochus or Phonognatha.
Bioprospecting Finds the Toughest Biological Material: Extraordinary Silk from a Giant Riverine Orb Spider
TLDR
Caerostris darwini produces the toughest known biomaterial, and this hypothesis predicts that rapid change in material properties of silk co-occurred with ecological shifts within the genus, and can be tested by combining material science, behavioral observations, and phylogenetics.
Phylogeny of extant nephilid orb‐weaving spiders (Araneae, Nephilidae): testing morphological and ethological homologies
TLDR
This work synthesizes the available data for the genera Nephila, Nephilengys, Herennia and Clitaetra to produce the first species level phylogeny of the Nephilidae, finding that nephilid genital morphologies coevolve with sexual behaviors and extreme sexual size dimorphism.
Dogs, cats, and kin: a molecular species-level phylogeny of Carnivora.
DNA barcoding gap: reliable species identification over morphological and geographical scales
TLDR
The results support models of independent patterns of morphological and molecular evolution by showing that DNA barcodes are effective in species identification regardless of their morphological diagnosibility and that the size of the barcoding gap strongly depends on taxonomic groups and practices.
