Macromorphological variation of the invasive Silverleaf nightshade (Solanum elaeagnifolium Cav.) and its relation to climate and altitude in Morocco

open access: yesRevue Marocaine des Sciences Agronomiques et Vétérinaires, 2019
The relationship between some morphological traits and the invasive potential of invasive alien plants has been reported. Also, biological invasion is often associated with rapid evolution in introduced species. The study aim was to provide the structure

Determination of Temperature and Light Optima for Seed Germination and Seedling Development of Spiderplant (Cleome gynandra L.) Morphotypes from western Kenya [PDF]

open access: yes, 2011
Spiderplant (Cleome gynandra) is an African indigenous vegetable (AIV) in many parts of sub-Saharan Africa, especially in most countries in eastern and southern Africa, where it is a semi-cultivated popular tropical species.

Effect of Septoria leaf blotch and its control with commercial fungicides, on arbuscular-mycorrhizal-fungal colonization, spore numbers, and morphotype diversity [PDF]

open access: yes, 2014
Arbuscular-mycorrhizal internal structures (i.e. total root colonization, arbuscules, vesicles) and external structures (i.e. spore density), and Glomeromycota spore morphotypes, were evaluated in wheat severely infected with Mycosphaerella graminicola –

Description of Two Morphotypes of Peptostreptococcus micros [PDF]

open access: yesInternational Journal of Systematic Bacteriology, 1993
Peptostreptococcus micros is often isolated from abscesses in several parts of the human body. The oral cavity is considered the natural habitat for the species, which has been implicated as a periodontal pathogen. In plaque samples from periodontitis patients we observed the presence of a rough morphotype of P.

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

open access: yesThe Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Benthic foraminifers and siliceous sponge spicules assemblages in the Quaternary rhodolith rich sediments from Pontine Archipelago shelf [PDF]

open access: yes, 2016
The bottom samples (Quaternary in age) of two cores (CS1 and Caro1) collected at 60 and 122 m water depth in the marine area near Ponza Island (Pontine Archipelago, Tyrrhenian Sea) are investigated.

Comparative in depth RNA sequencing of P. tricornutum’s morphotypes reveals specific features of the oval morphotype [PDF]

open access: yesScientific Reports, 2018
AbstractPhaeodactylum tricornutumis the most studied diatom encountered principally in coastal unstable environments. It has been hypothesized that the great adaptability ofP.tricornutumis probably due to its pleomorphism. Indeed,P.tricornutumis an atypical diatom since it can display three morphotypes: fusiform, triradiate and oval.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Morphological Diversity of Coleoptera (Arthropoda: Insecta) in Agriculture and Forest Systems

open access: yesRevista Brasileira de Ciência do Solo, 2017
Coleopterans (Coleoptera) are major ecosystem service providers. However ecomorphological features that are comparable in a wide range of invertebrates within this group and in various environments must be found, to be able to study regions with ...

Study of planktonic morphotype of the Abderaz Formation at type section, Iran [PDF]

open access: yes, 2009
Abderaz Formation at its type section with an age of Turonian-Early Campanian and a thickness of 300 m contains light grey shale and marl. The study of the planktonic foraminifera in isolated form led to differentiate three morphotype groups.
