How Many Sipunculan Species Are Hiding in Our Oceans?

open access: yesDiversity, 2021
Sipuncula, long considered a separate phylum, are now commonly included in the Annelida based on phylogenomic analyses. The sipunculan body consists of an unsegmented trunk and a retractable introvert, usually with a set of tentacles at its anterior end.

Do evolutionary algorithm dynamics create complex network structures? [PDF]

open access: yes, 2021
This paper presents a novel method for visualizing the dynamics of evolutionary algorithms in the form of complex networks. We discuss the analogy between individuals in populations in an arbitrary evolutionary algorithm and vertices of a complex network,

Species Recognition and Cryptic Species in the Tuber indicum Complex

open access: yesPLoS ONE, 2011
Morphological delimitation of Asian black truffles, including Tuber himalayense, T. indicum, T. sinense, T. pseudohimalayense, T. formosanum and T. pseudoexcavatum, has remained problematic and even phylogenetic analyses have been controversial. In this study, we combined five years of field investigation in China with morphological study and DNA ...

Use of the Genealogical Sorting Index (GSI) to delineate species boundaries in the Neofusicoccum parvum-Neofusicoccum ribis species complex [PDF]

open access: yes, 2011
Neofusicoccum is a recently described genus of common endophytes and pathogens of woody hosts, previously placed in the genus Botryosphaeria. Many morphological characteristics routinely used to describe species overlap in Neofusicoccum, and prior to the

Temporal and spatial variation in population structure among brooding sea stars in the genus Leptasterias

open access: yesEcology and Evolution, 2021
Temporal genetic studies of low‐dispersing organisms are rare. Marine invertebrates lacking a planktonic larval stage are expected to have lower dispersal, low gene flow, and a higher potential for local adaptation than organisms with planktonic ...

Cylindrocarpon root rot: multi-gene analysis reveals novel species within the Ilyonectria radicicola species complex [PDF]

open access: yes, 2011
Ilyonectria radicicola and its Cylindrocarpon-like anamorph represent a species complex that is commonly associated with root rot disease symptoms on a range of hosts.

Species diversity and molecular characterization of Alternaria section Alternaria isolates collected mainly from cereal crops in Canada

open access: yesFrontiers in Microbiology, 2023
Alternaria is often one on the most abundant fungal genera recovered from a wide array of plant hosts and environmental substrates. Many species within the sub-generic Alternaria section Alternaria are common plant pathogens that cause pre-harvest losses

DNA sequence incongruence and inconsistent morphology obscure species boundaries in the Teratosphaeria suttonii species complex [PDF]

open access: yes, 2012
Teratosphaeria suttonii (=Kirramyces epicoccoides) is a leaf pathogen that can cause premature defoliation, reduced growth and vigor, and subsequent tree death of many Eucalyptus species.
