Resumen: En Andalucía tiene lugar, como en toda España, un aumento en los nacimientos de 1996 a 2008 y un descenso posterior. Este proceso está relacionado con el retraso en la edad de la maternidad de las mujeres españolas de las generaciones numerosas nacidas durante el baby boom, y con la llegada de mujeres extranjeras con diferencias en la intensidad y la edad de la fecundidad. Para ayudar a conocer la situación y perspectivas de la demanda de servicios sanitarios, en nuestro estudio hemos tratado de conocer si estos procesos de aumento y disminución de los nacimientos, y los cambios sociales relacionados se han dado por igual en los 33 distritos sanitarios de Andalucía. Hemos estudiado los nacimientos del periodo con datos publicados sobre nacionalidad de las madres (2001-2011). Hemos comenzado constatando las diferencias en la fecundidad según nacionalidad a nivel regional y provincial, para terminar comprobando la existencia de grandes disparidades en la edad, la nacionalidad y la fecundidad de las mujeres en los distritos sanitarios andaluces que han influido en el número y la evolución de los nacimientos, pudiendo diferenciar cinco tipos de distritos: 1) Siete distritos con mujeres jóvenes españolas y alta fecundidad retrasada en áreas metropolitanas, 2) Seis distritos con muchas mujeres jóvenes extranjeras y alta fecundidad más o menos precoz según nacionalidad, 3) Nueve distritos envejecidos por emigración secular, con baja fecundidad y donde han llegado muy pocas extranjeras, 4) Siete distritos envejecidos por emigración secular, con baja fecundidad y donde han venido a residir mujeres mayores extranjeras de Europa occidental, 5) Cuatro distritos urbanos envejecidos por salida de jóvenes españolas hacia las áreas metropolitanas, pero mantienen los nacimientos gracias a las mujeres extranjeras jóvenes que han ido a trabajar a la ciudad. Abstract: In Andalusia takes place an increase in the number of births from 1996 to 2008 and a subsequent decline takes place, as throughout Spain. This process is related to the delay in childbearing age in Spanish women of many generations born during the baby boom, and with the arrival of foreign women with differences in the intensity and age of fertility. To help understand the situation and outlook for demand for health services, in our study we sought to determine whether these processes increase and decrease of births, and related social changes have occurred equally in all 33 health districts of Andalusia. We have studied the birth period with published data on nationality of mothers (2001-2011). We have started noting the differences in fertility according to nationality at regional and provincial levels, to finish checking the existence of large disparities in age, nationality and the fertility of women in Andalusian health districts that have influenced the number and evolution of births and can distinguish five types of districts: 1) Seven districts with young Spanish women and delayed high fertility in metropolitan areas, 2) Six districts with a lot of young foreign women and high fertility more or less early by nationality, 3) Nine districts aged for secular emigration, low fertility and where very few foreign have reached 4) Seven districts aged for secular emigration, low fertility with where foreign women from Western Europe 5) Four urban aged districts due to migration of young Spanish to metropolitan areas, that maintain the number of births thank to young foreign women who have come to work in the town.

On Farm

Agroforests and woodlots offer Northland hill country farmers investment and diversification opportunities. Agroforests have less effect on the "whole farm" financial position than woodlots, especially where a progressive planting regime is adopted and where no further borrowing is required. Establishment and tending costs for agro-forests are lower, and returns come much sooner. The proven opportunity for continued grazing under trees established in this manner, apart from a short post-planting period, further enhances the agroforesty option. Even where there is reluctance on a farmer's part to plant trees on high fertility land, the expected financial returns from agroforests on low and medium fertility land will increase the overall long-term profitability and flexibility of the whole farming operation. Woodlots may be more appropriate on low fertility areas where weed reversion is likely. Joint ventures may be worth considering where farm finances are a limited factor.

Lower Fertility

It has been argued by many demographers that socio economic development with its associated fundamental changes in the role of women and the value of children is the dominant factor in the transition from high to low fertility. Research in less developed countries has found lower fertility levels in urban population compared to rural population. It was therefore assumed that the modernizing role of urbanlife helped bring about a decline infertility levels.This study in Irian Jaya, however, convincingly shows that fertility of urban women in Irian Jaya is higher than that of rural women. This differential infertility in favour of urban women in Irian Jaya appears to be real and not a result of underreporting of total live births in rural areas.The reasons for lower fertility in the rural areas in IrianJaya remain unknown, and more research is therefore needed. However, this study strongly suggests that the traditional system of swidden agricultyure in Irian Jaya, which places a highvalue on the labour input of women, may play a major role in constraining fertility in rural area of this province. On the other hand, high fertility in urban areas takes place because urbanwomen have their first birth earlier thanwomen inthe rural areas.

Aim. A comparative analysis of the cytological manifestation in the meiosis of six meiotic mutants was carried out. Methods. Buds with anthers 2–3 mm long fixed in ethanol: glacial acetic acid in a ratio of 3:1, were stored in 70 % ethanol, stained with acetocarmine. For cytology preparations prepared pressure anthers at various stages of meiosis. Pollen fertility was determined by staining with acetocarmine. Results. Meiotic mutations tomato dsm1, dsm2, dsm3, as1, as5 and asb not affect the vegetative growth of plants, but have low fertility of pollen and number of seeds in the fruit. They are similar cytological manifestation. The beginning of meiosis occurred apparently normal, as violations of premature decay bivalent observed since diplotenе. Chiasma frequencies in pollen mother cells ranged from 8.13 to dsm3 / dsm3 to 6.73 in asb / asb. All investigated mutations revealed monogenic recessive character of inheritance. Mutations as1, as5 and asb and dsm2 are not allelic to each other. The mutation dsm1 appeared allelic to mutations dsm2 and asb. Conclusions. Investigated meiotic mutations failure of chiasma maintenance in the pollen mother cells with varying degrees of desynapsis. Based on the fact that the previously published data did not reveal a reduction in the recombination frequency in marked areas of the genome, we anticipate premature removal of cohesin that hold sister chromatids distal chiasmata.Keywords: meiosis, meiotic mutants, sister chromatids cohesion, premature separation of the bivalents, Lycopersicon esculentum Mill.

Operational Assessment

The article presents the results of an operational assessment of the impact of the COVID-19 crisis on the change in the gross urban product (GUP) in 17 metropolitan areas of Russia with a population of more than 1 million people in 2020. The goal of the authors was to try to answer the most actual questions nowadays (early 2021): how deep was the fall of the largest agglomerations economies in Russia and abroad; did the corona crisis have a more negative impact on the largest metropolitan areas then on the rest of the economy? In order to answer these questions, two main tasks were: 1) to assess GUP in 17 largest metropolitan areas of Russia; 2) to consider foreign estimates of the GUP in 2020. For foreign comparisons, the authors use the first published data on changes in GDP and gross urban/regional product in the United States, Canada and Australia. The assessment of GUP in this work is carried out through the assessment of the component of employee compensation and then the transition to the GUP indicator on the assumption that such a ratio of compensation of employees to GDP in a city equals the average of the said ratios for the 17 metropolitan areas. The assessment showed that the real GDP growth rates in 2020 were negative not in all metropolitan areas, and in most of them economic losses turned out to be less than those of the Russian economy as a whole.

Semen cryopreservation determines several sperm damages, including the loss of fertility-associated proteins. The purpose of the study was to compare the metabolite contents in bovine sperm and seminal plasma before and after cryopreservation, and between high- and low-fertility bulls in vitro. Forty-eight ejaculates, collected from eight bulls (six per bull), were analyzed by liquid chromatography–mass spectrometry. Cryopreservation resulted in an over-expression of lysophosphatidylcholine (0:0/18:2(9Z,12Z)) in seminal plasma. In addition, higher levels of glycine betaine and pyro-l-glutaminyl-l-glutamine were observed in cryopreserved compared to fresh spermatozoa. The fresh seminal plasma of high-fertility bulls showed an over-expression of l-acetylcarnitine, glycerol tripropanoate, 2,3-diacetoxypropyl stearate and glycerophosphocholine, and an under-expression of lysophosphatidylcholine and butyrylcarnitine, compared to low-fertility bulls. Higher levels of glycerophosphocholine and lysophosphatidylcholine (16:0/0:0) were recorded in fresh spermatozoa from high-fertility bulls. In high-fertility bulls, a greater content of glycerophosphocholine and lower levels of butyrylcarnitine, glycine betaine and l-carnitine were found in cryopreserved seminal plasma, and lower levels of glycine betaine were detected in cryopreserved spermatozoa. In conclusion, cryopreservation affects bovine semen metabolome at both plasmatic and cellular compartments, and metabolic profile differs between high- and low-fertility bulls.

Perceived Costs

Abstract The aim of this study was to examine the positive relationship between religiosity and fertility from the perspective of perceived consequences of parenthood. Previous studies in Germany have found that highly religious people ascribe higher benefits and lower costs to having children. Furthermore, the impact of costs and benefits on fertility is less pronounced among the highly religious. This study tested these mechanisms for fertility intentions and in the context of Poland – a country with a low fertility rate and high religiosity in comparison to other European countries. A sample of 4892 men and women of childbearing age from the second wave of the Polish version of the Generations and Gender Survey conducted in 2014/2015 was used. First, the extent to which perceived costs and benefits mediate the impact of religiosity on fertility intentions was analysed. Second, whether religiosity moderates the impact of perceived costs and benefits on fertility intentions was investigated. The results show that part of the positive effect of religiosity on fertility intentions can be explained by more-religious people seeing higher benefits of having children. Furthermore, but only in the case of women, religiosity moderates the impact of perceived costs on fertility intentions, suggesting that the effect of perceived costs decreases with increasing religiosity.

Genetic Merit

SummaryThe present study was aimed to investigate differences in molecular signatures in oocytes derived from Holstein-Friesian heifers with different genetic merit for fertility, euthanized during day 0 or day 12 of the estrous cycle. Moreover, association between single nucleotide polymorphisms (SNPs) of ODC1 and STAT3 genes and bull fertility traits was investigated. The gene expression patterns were analyzed using cDNA array and validated with quantitative real-time polymerase chain reaction (PCR). The result revealed that several genes have shown not only to be regulated by fertility merit but also by the day of oocyte recovery during the estrous cycle. The STAT3 gene was found to be upregulated in oocytes recovered from animals with high fertility merit at both day 0 and day 12. Some other genes like PTTG1, ODC1 and TUBA1C were downregulated at day 0 and upregulated at day 12 in high, compared with low, fertility merit recovered oocytes. In contrast, the transcript abundance of TPM3 was upregulated at day 0 and downregulated at day 12 in high, compared with low, fertility merit recovered oocytes. In addition, ODC1 and STAT3 were found to be associated (P < 0.05) with sperm quality traits as well as flow cytometry parameters. Therefore, the expression of several candidate genes including ODC1 and STAT3 was related to the genetic merit of the cow. In addition polymorphisms in these two genes were found to be associated with bull semen quality.

Childbearing Intentions

AbstractChildbearing intentions among women in high-fertility contexts are usually classified into those wanting to have a baby, those wanting to ‘space’ a birth and those wanting to ‘limit’ their family size. However, evidence from Africa increasingly suggests that women’s intentions are more complex than this classification suggests, and that there is fluidity in these intentions. This research explores women’s accounts of their childbearing intentions and decisions in order to examine how this fluidity plays out in a low-fertility context in urban Africa. Six focus group discussions were conducted in April and May 2012 with women of reproductive age in Nairobi, Kenya. Participants were recruited using random and purposive sampling techniques. The focus group discussions had an average of seven participants each. Data were coded thematically and analysed using Nvivo software. The analysis explored the factors that women consider to be influential for childbearing and found that the health of the mother and child, costs of raising a child and relationships were commonly reported to be important. Evidence of intentions to space births and limit family size was found. However, the data also showed that there is fluidity in women’s family planning intentions, driven by changes in relationships or household finances, which often result in a desire to avoid pregnancy in the present moment. The fluidity observed in women’s childbearing intentions cannot be accounted for by the concepts of either ‘spacing’ or ‘limitation’ but is best explained by the concept of ‘postponement’. The research reveals the need for family planning clinics to provide a full method mix, as well as high-quality counselling, to enable women to choose a method that best suits their needs.
