Microbiome Analysis of Malacopathogenic Nematodes Suggests No Evidence of a Single Bacterial Symbiont Responsible for Gastropod Mortality

open access: yesFrontiers in Immunology, 2022
Nematodes and bacteria are prevalent in soil ecosystems, and some have evolved symbiotic relationships. In some cases, symbionts carry out highly specialized functions: a prime example being entomopathogenic nematodes (EPNs), which vector bacteria ...

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

THE EVOLUTION OF APOSEMATISM IN MARINE GASTROPODS [PDF]

open access: yesEvolution, 1991
In a recent review of the literature on marine gastropods, Rosenberg (1989) concludes that in this group,".. . as in the lepidopterans, . . . individual selection is the predominant mode of evolution of warning coloration." Rosenberg's analysis raises interesting issues concerning the evolution of aposematism generally, and in marine gastropods in ...
