Abstract:

Examination of <i>Eucyclops</i> populations coming from Algerian water bodies and identified as Eucyclops cf. serrulatus showed three morphotypes, based on morphometric characters and microcharacters. Morphotype 1 was the most abundant, collected in the east and the west of Algeria. Morphotype 2 was sampled in the south of the country, characterised by posterolaterally elongated thoracic segments and the fourth thoracic segment bearing cilia on its lateral angles. Morphotype 3 was found in a small temporary pond in the north of the country and was the smallest one. Other differences were obser

Abstract:

In temporary ponds, seed germination largely determines how well aquatic plant assemblages recover after dry periods. Some aquatic plants have terrestrial morphotypes that can produce seeds even in dry years. Here, we performed an experiment to compare germination patterns for seeds produced by aquatic and terrestrial morphotypes of Ranunculus peltatus subsp. saniculifolius over the course of five inundation events. During the first inundation event, percent germination was higher for terrestrial morphotype seeds (36.1%) than for aquatic morphotype seeds (6.1%). Seed germination peaked for bot

A detailed investigation of the morphological evolution of the coccolithophorids Calcidiscus leptoporus and C. macintyrei from the Early Miocene to the Quaternary shows that microevolutionary patterns were very complex. Speciation patterns such as cladogenesis and phyletic divergence were observed, but stasis also existed over prolonged time-intervals. Similar coccoliths developed repeatedly at stratigraphically distant intervals, leading to taxonomic uncertainies. On the basis of bivariate frequency diagrams of coccolith diameters and number of elements in the distal shields nine morphotypes

Abstract:

The scope of adaptive phenotypic change within a lineage is shaped by how functional traits evolve. Castes are defining functional traits of adaptive phenotypic change in complex insect societies, and caste evolution is expected to be phylogenetically conserved and developmentally constrained at broad phylogenetic scales. Yet how castes evolve at the species level has remained largely unaddressed. Turtle ant soldiers (genusCephalotes), an iconic example of caste specialization, defend nest entrances by using their elaborately armored heads as living barricades.

Abstract:

Intrataxonomic differences in terms of angiosperm suitability for herbivorous insects stem from variables such as plant structure, palatability, and chemistry. It has not yet been elucidated whether these differences also occur in terms of the bryophyte’s suitability to bryophages. Hypnum cupressiforme Hedw. is a morphologically variable moss species frequently inhabited or fed by insects. In this investigation, we offered five morphotypes of H. cupressiforme to two bryophagous species of Byrrhidae (Coleoptera) to reveal whether the intrataxonomic variability affects beetles’ preferences.

Cenococcum geophilum, the most abundant morphotype, occurred in 75% of soil cores. Another common morphotype yielded a restriction fragment length polymorphism (RFLP) pattern similar to that of Tuber species. Uncommon morphotypes were responsible for the major

An important feature of ruminal ciliates is their phenotypic plasticity, which makes their identification difficult. The common manifestation of the phenotypic plasticity in rumen ciliates is a change in their cell size and caudal spination. We analyzed various morphotypes of Epidinium with five caudal processes (spines) taken from the rumen of European bison (Bison bonasus). In the study, the cluster analysis and K-means analysis of morphometric data could not distinguish very similar morphotypes of Epidinium with five caudal processes. However, the morphotype of E. parvicaudatum prevailed (7

We examined 754 women for pH, homogeneous vaginal discharge, amine odour, clue cells and the composite clinical diagnosis. We also examined wet mounts for small bacterial morphotypes and lactobacillary morphotypes, and weighted their quantitative presence as a bacterial morphotype score.
