Lobelia Lakes' Vegetation and Its Photosynthesis Pathways Concerning Water Parameters and the Stable Carbon Isotopic Composition of Plants' Organic Matter.

Most of the aquatic vegetation produces organic substances via the C3 photosynthetic pathway (mosses, isoetids- L., (L.) Raf.

[Unification of pathomorphological examination of patients with neuroendocrine tumors of the pituitary gland. Controversial issues of the new classification].

The progressive improvement of the classification using modern analytical methods is an essential tool for the development of precise and personalized approaches to the treatment of pituitary adenomas. In recent years, endocrinologists have witnessed evolutionary changes that have occurred in the histopathological identification of pituitary neoplasms, revealing new possibilities for studying tumorigenesis and predicting biological behavior.The paper considers the historical aspects of the gradual improvement of the classification of pituitary adenomas, as well as the new international 2022 WHO classification, according to which pituitary adenomas are included in the list of neuroendocrine tumors (PitNETs) to reflect the biological aggressiveness of some non-metastatic pituitary adenomas.

Playing Hard-to-Get: A New Look at an Old Strategy.

According to dating folklore, playing "hard-to-get" is an effective strategy for attracting prospective mates. However, some research suggests that this strategy could backfire if it leads prospective mates to withhold their attraction in return. The present research aimed to review the scope of research on the link between playing hard-to-get - i.

Functional macrophyte trait variation as a response to the source of inorganic carbon acquisition.

Background: This study aims to compare variation in a range of aquatic macrophyte species leaf traits into three carbon acquisition groups: HCO , free CO and atmospheric CO.

Methods: The leaf functional traits were measured for 30 species from 30 softwater lakes. Macrophyte species were classified into (1) free CO, (2) atmospheric CO and (3) bicarbonate HCO groups.

Can nutrient uptake by Carex counteract eutrophication in fen peatlands?

Ground- and surface-water-fed peatlands (i.e., fens) of temperate Europe face high anthropogenic nutrient loads from atmospheric deposition, agricultural catchment areas, and from peat decomposition, if drained.
