Phenotypic senescence and multilevel variation in different body sizes in a natural insect population

Kata Pásztor, Ádám Kőrösi, Ádám Gór & János Kis
Senescence seems to be universal in living organisms and plays a major role in life-history strategies. Phenotypic senescence, decline of body condition and/or performance with age, is a largely understudied component of senescence in natural insect populations, although it would be important to understand how and why insects age under natural conditions. We aimed a) to investigate how body mass and thorax width change with age in a natural population of the univoltine Clouded Apollo...

Biological control properties of microbial plant biostimulants. A review

Sri Ita Tarigan, Szabolcs Toth, Mark Szalai, Jozsef Kiss, Gyorgy Turoczi & Stefan Toepfer
Plant biostimulants, sometimes referred to as biofertilisers or plant enhancers, are ingredients stimulating plant nutrition processes independently of the product’s nutrient content with the sole aim to improve the agronomic performance of a plant. Many of these biostimulants contain microorganisms. Although most of these microorganisms are supposed to only promote plant growth, some have plant protection properties. We reviewed commercial microbial plant biostimulants with regard to their potential effects on insects. This revealed 483 different...

Loss of ubiquitinated protein autophagy is compensated by persistent cnc/NFE2L2/Nrf2 antioxidant responses

Arindam Bhattacharjee, Adél Ürmösi, András Jipa, Levente Kovács, Péter Deák, Áron Szabó & Gábor Juhász
SQSTM1/p62-type selective macroautophagy/autophagy receptors cross-link poly-ubiquitinated cargo and autophagosomal LC3/Atg8 proteins to deliver them for lysosomal degradation. Consequently, loss of autophagy leads to accumulation of polyubiquitinated protein aggregates that are also frequently seen in various human diseases, but their physiological relevance is incompletely understood. Here, using a genetically non-redundant Drosophila model, we show that specific disruption of ubiquitinated protein autophagy and concomitant formation of polyubiquitinated aggregates has hardly any effect on bulk autophagy, proteasome activity...

Dietary flexibility promotes range expansion: the case of golden jackals in Eurasia

József Lanszki, Matthew W. Hayward, Nathan Ranc & Andrzej Zalewski
Aim: Exploring the drivers of the successful ongoing expansion of the golden jackal across Europe is essential to understand the species’ trophic ecology. We analysed which climatic and environmental factors affected the dietary composition of golden jackals and compared these drivers in the species’ historic and recently colonised distribution ranges. Location: Eurasia. Taxon: golden jackal (Canis aureus). Methods: Using 40 published data sets, we modelled the diet composition using 13 food categories based on the...

Data from: White plumage color as an honest indicator: feather macrostructure links reflectance with reproductive effort and success

Miklós Laczi, Mónika Jablonszky, Gábor Markó, Gergely Nagy, Gyula Szabó, Sándor Zsebők, János Török & Gergely Hegyi
The structural condition of feathers may generally have a decisive role in shaping the color properties of the plumage. However, the information content of structurally mediated color differences is poorly known. This makes it particularly hard to determine the meaning of color variation in pigment-free white plumage patches. The white wing patch of the collared flycatcher (Ficedula albicollis) is an important sexual trait, and changes in its reflectance are partly due to macrostructural condition. We...

Alterations of the expression levels of glucose, inflammation, and iron metabolism related miRNAs and their target genes in the hypothalamus of STZ-induced rat diabetes model

Edina Pandur, István Szabó, Edina Hormay, Ramóna Pap, Attila Almási, Katalin Sipos, Viktória Farkas & Zoltán Karádi
Abstract Background The hypothalamus of the central nervous system is implicated in the development of diabetes due to its glucose-sensing function. Dysregulation of the hypothalamic glucose-sensing neurons leads to abnormal glucose metabolism. It has been described that fractalkine (FKN) is involved in the development of hypothalamic inflammation, which may be one of the underlying causes of a diabetic condition. Moreover, iron may play a role in the pathogenesis of diabetes via the regulation of hepcidin,...

Basic income as a tool to support aggregate demand

Askar Akaev, Alexander Petryakov, Nauryz Baizakov & Zoltán Zéman
The developed economies of the world are now facing new challenges, the main of which are: the degree of human participation in the production process, in which it will not be an “appendage” of new intelligent systems; prevention of further social and economic polarization of society; development of new economic tools to mitigate the negative effects of extensive digitalization of production and services. This paper shows that conditional basic income as a macroeconomic policy tool...
