Pointwise approximation of 2 π/r-periodic functions by matrix operators of their Fourier series with r-differences of the entries

open access: yesDemonstratio Mathematica, 2018
We extend the results of Xh. Z. Krasniqi [Acta Comment. Univ. Tartu. Math., 2013, 17, 89-101] and the authors [Acta Comment. Univ. Tartu. Math., 2009, 13, 11-24] to the case of 2 π/r-periodic functions.

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

open access: yesPest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Pointwise approximation of modified conjugate functions by matrix operators of their Fourier series; pp 50-60 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2018
We extend the results presented by Xh. Z. Krasniqi (Slight extensions of some theorems on the rate of pointwise approximation of functions from some subclasses of Lp. Acta Comment. Univ. Tartu. Math., 2013, 17, 89–101) and W. Lenski and B.

Transcriptomic resources and functional validation of RNAi in the cabbage seedpod weevil, Ceutorhynchus obstrictus

open access: yesPest Management Science, EarlyView.
Transcriptome sequencing of Ceutorhynchus obstrictus revealed RNA interference (RNAi) targets; double‐stranded RNA microinjection reduced transcript levels and increased mortality, with αCOP and Rop showing strongest lethal effects, indicating promising RNAi‐based pest control candidates.

Pollinator community composition and pollen resource use in calcareous grasslands under different landscape contexts across Europe

open access: yesJournal of Animal Ecology, EarlyView.
In this paper, we show that pronounced differences in pollinator communities exist between grasslands embedded in contrasting agricultural landscape contexts. Opportunistic foraging strategies of most pollinators resulted in large interaction turnover, but these shifts did not translate into major changes in overall network structure, most likely as a ...
