The majority of our knowledge of avian energetics is based on studies of birds from temperate and high latitudes. Using the largest existing sample of wild-caught Old World tropical species, we showed that birds from Southern Vietnam had lower basal metabolic rate (BMR) than temperate species. The strongest dissimilarity between tropical and temperate species was the low scaling exponent in the allometric relation between BMR and body mass in tropical birds (the regression slope was 0.573). The passerine migrants to temperate and high latitudes had higher BMR than tropical sedentary passerines. Body mass alone accounted for 93% of the variation in BMR (body mass ranged from 5 to 252 g). Contrary to some other studies, we did not find evidence besides the above mentioned that phylogeny, taxonomy, behavior, or ecology have a significant influence on BMR variation among tropical birds.

The research presented in this paper discusses the impact that the parameters of charge(Q)and screening factor(γ)have on properties of the horizon and silhouette of rotating charged Mod Max black holes which were reviewed in[***.J.C(2022)82:1155]recently,building upon previous findings in the ***,the study explores the behavior of null geodesics,which can help us better understand the apparent shape of the black hole’s silhouette,as well as the distortion parameter and approximate radii of the silhouette that are influenced by the aforementioned parameters,and there are some values of parameter Q which corresponds to data from the Event Horizon Telescope(EHT).Notably,we explore the distortion parameter and approximate radii of the silhouette,revealing that while an increase inγleads to a growth in silhouette radius(Rs),it simultaneously reduces the distortion rate(δs).Conversely,heightened Q charge results in a reduction of Rsaccompanied by an increase inδ***,the paper analyzes the effects of the black hole’s parameters on the effective potential and energy emission:the peak value of the energy emission rate experiences a decrease as the screening factor(γ)increases,while it increases with higher values of the charge parameter(Q).

We found that, within a cohort, mean colour type changed mainly between the ringing year （mean colour type = 4.5） and the year of first recapture （mean colour type = 3.8;difference = 0.7）, and did not alter significantly afterwards (mean colour type

In this article, for the first time applied in our republic, the results of the effect of nano-micro fertilizers on cotton plant are given. The results of the study of the effect of microelements on the leaf area, plant height formation and yield of cotton in the conditions of the gray soil of the Zarafshan Valley are presented. Currently, the demand for ecological and safe food is increasing not only in Uzbekistan, but also in the whole world. The solution to this problem is effective use of land and increasing the amount of macrofertilizers, and after increasing the yield per unit of area, the micronutrients in the soil will decrease more, and less attention was paid to fertilizing with trace elements. This will affect the quality of the product, as well as the decrease in productivity and salinity of the land. Therefore, it is necessary to develop environmentally friendly and more economical approaches that do not harm the environment. The best solution for this is to reduce micronutrient deficiency in combination with agrotechnical methods. One of the urgent issues is the development of the technology of applying macro- and micro-fertilizers in the appropriate proportions, convenient terms, norms and methods for the cultivation of high-quality cotton crops under the soil conditions of our republic. The optimal rate of using microelements had a positive effect on the leaf area and dry mass of cotton plants. The highest result was observed when N200P140K100 + KUPRUMHITE + NANOSEREBRO kg/ha was applied with mineral fertilizer.
