Two new species of Laboulbeniales are described: Laboulbenia parasyphraeae, parasitic on Parasyphraea sp. (Coleoptera, Chrysomelidae, Alticinae), and L. skelleyi, parasitic on Pselaphacus rubricatus and P. signatus (Coleoptera, Erotylidae). Other recorded species are Chaetomyces pinophili, Chitonomyces aurantiacus, Corethromyces ophitis, Dimorphomyces platensis, Dioicomyces anthici, D. cf. noto...

Birth–death models are central to much macroevolutionary theory. The fundamental parameters of these models concern durations. Different species concepts realize different species durations because they represent different ideas of what birth (speciation) and death (extinction) mean. Here, we use Cenozoic macroperforate planktonic foraminifera as a case study to ask: what are the dynamical cons...

In eastern Asia and western North America at least nine morphologically distinguishable species of digenean trematode infect the mud snail, Batillaria attramentaria (Sowerby 1855) (=B. cumingi (Crosse 1862)), as first intermediate host. Further, molecular and morphological evidence indicates that several of these trematode species comprise complexes of cryptic species. I present an identificati...

Two new conifer morphospecies represented by a secondary xylem are reported for the Lower Cretaceous Baqueró Group (Santa Cruz Province, Argentina). Agathoxylon sp. is characterized by poorly defined growth rings, predominantly uniseriate pitting in the radial wall of the tracheids, cross fields with 1-6 pits and uniseriate rays. These features are shared with the leafy branches described for t...

The present investigation focuses on the Global Sea Mineral Resources contract area B4S03 site in Clarion-Clipperton Fracture Zone nodule fields. We investigated sedimentary characteristics and higher-taxon (order/class) lower-taxon (family, morphospecies) diversity of soft sediment macrobenthos with special focus dominant taxa (Isopoda, Polychaeta, Tanaidacea) relation to abundance. Across all...

The common non-marine ostracod Cypridopsis vidua (O.F. Müller, 1776) is used as a proxy in various biological disciplines, such (palaeo-)ecology, evolutionary biology, ecotoxicology and parasitology. This morphospecies was considered to be an obligate parthenogen. We report on the discovery of first population C. with males from Woods Hole (MA, USA) determine that it mixed reproduction. describ...

Botrytis cinerea is an important pathogen that causes diseases in ornamental crops. In presentresearch several greenhouses of roses located in central region of Iran were surveyed toidentify the Botrytis cinerea. A total of 80 isolates were collected from rose greenhouses incentral region of Iran. Morphological identification was based on characters such asconidiophore and conidial length. Acco...

Among the natural enemies of insect pests in rice fields, parasitoids are especially notable. To better understand the space-time dynamics of these insects, the objectives of this study were to describe and compare groups of parasitoids in organic irrigated rice fields using two management approaches for levee vegetation, and to relate them to the phenological stages of rice cultivation (the se...
