THE USE OF THE ECOLOGICAL CALENDAR IN THE PROCESS OF ACQUAINTANCE OF OVER-FIVE PRESCHOOL CHILDREN WITH SEASONAL CHANGES IN NATURE

open access: yesВестник Мининского университета, 2018
Introduction: The article examines the important problem of the formation of pre-schoolers' views on the change of seasons, patterns and features of seasonal changes in nature. The approaches to solving this problem existing in science are stated briefly,

The grasshopper problem [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017
We introduce and physically motivate the following problem in geometric combinatorics, originally inspired by analysing Bell inequalities. A grasshopper lands at a random point on a planar lawn of area 1. It then jumps once, a fixed distanced, in a random direction.

Phenotypic pattern over centric fusion clinal variation in the water-hyacinth grasshopper, Cornops aquaticum (Orthoptera: Acrididae) [PDF]

open access: yes, 2018
The water-hyacinth grasshopper, Cornops aquaticum, occurs in freshwater environments in the New World between latitudes 23°N and 35°S. At the southernmost margin of this distribution the populations are polymorphic for three centric fusions (Robertsonian

Control of Pest Grasshoppers in North America

open access: yesInsects, 2020
Grasshoppers (Orthoptera: Acrididae) frequently inflict damage on millions of hectares of western rangelands and crops. The main method of controlling grasshopper outbreaks consists of covering their infestations with chemical insecticides.
