Abstract:
Global species extinction typically represents the endpoint in a long sequence of population declines and local extinctions. In comparative studies of extinction risk of contemporary mammalian species, there appear to be some universal traits that may predispose taxa to an elevated risk of extinction. In local population-level studies, there are limited insights into the process of population decline and extinction. Moreover, there is still little appreciation of how local processes scale up to global patterns. Advancing the understanding of factors which predispose populations to rapid declines will benefit proactive conservation and may allow us to target at-risk populations as well as at-risk species. Here, we take mammalian population trend data from the largest repository of population abundance trends, and combine it with the PanTHERIA database on mammal traits to answer the question: what factors can be used to predict decline in mammalian abundance? We find in general that environmental variables are better determinants of cross-species population-level decline than intrinsic biological traits. For effective conservation, we must not only describe which species are at risk and why, but also prescribe ways to counteract this.

The paper points out advantages and limitations of contemporary age-structural transition. Age-structural transition may create favorable conditions for fulfillment of millennium development goals, However, it cannot create sustainable demographic development and remove danger of extinction of some nations. The only remedy is family planning program and huge financial resources that will support it for a long period of time.

Abstract:
SummaryPopulations of farmland and long-distance migratory birds have suffered steep, often dramatic, declines in the last few decades. The Barn Swallow Hirundo rustica is a small migratory farmland bird that breeds synanthropically in farms, particularly where livestock is reared. Populations of this species have suffered marked declines in different parts of its European breeding range. Here, we first report a dramatic decline of 8.4% per year of the number of breeding pairs and the extinction of 19.6% of the colonies in three agricultural areas in Northern Italy, which differ in general ecological conditions. This decline was estimated on a very large sample of 190 randomly chosen farms where breeding pairs were censused both in 2001 and 2010, and occurred at different rates in the three study areas. Barn Swallows declined most (9.3% per year) in an intensively cultivated area where colonies are widespread, and least (1.3% per year) in a hilly area with a comparatively small density of colonies. Variation in livestock farming significantly influenced population dynamics. Specifically, cessation of livestock farming at a given farm between the two census years resulted in a significantly steeper decline in the number of breeding pairs compared to farms where livestock farming was maintained. Our findings highlight the fact that European populations of Barn Swallows breeding in intensively cultivated agro-ecosystems may become significantly depleted in the next decades, and indicate that maintenance of livestock farming may contribute to buffering the population decline of this species.

Abstract:
Long-term surveys indicate that the scaup populations have declined over the past 20 years, and that this is probably the result of decreases in Lesser Scaup (Aythya affinis) rather than Greater Scaup (Aythya marila) numbers. To identify factors possibly related to the decline, we estimated demographic parameters for a local population of Lesser Scaup at Erickson, Manitoba, that was well studied before declines occurred and compared these estimates to historic rates. On average, nests were initiated later than in the past, and recent estimates of nesting success and duckling survival were lower than historical estimates. Breeding-season survival of adult females was estimated as 72.6%, with most (83%) mortality occurring during nesting. Current estimates of demographic rates at Erickson are too low to maintain a stable local population, and suppressed reproductive rates might be the proximate cause of the local population decline.

Abstract:
AbstractMany aphid species (Hemiptera: Aphididae) that feed on herbaceous crops exhibit a rise and then sudden decline in abundance. Data from a nine-year study of Uroleucon rudbeckiae (Fitch) on Rudbeckia laciniata Linnaeus (Asteraceae) are used to investigate this pattern of seasonal abundance in a non-agricultural aphid. Aphids on a population of tagged and numbered flower stems were counted weekly. Abundance (mean aphids per stem) was partitioned into prevalence (proportion of stems colonised) and mean intensity (aphids per colonised stem), and also considered as the sum of the aphids in individual colonies. Abundance rose in mid-summer to late summer and then declined, peaking between the end of July and mid-September, earlier in years when the peak was higher. Prevalence showed a more uniform and consistent peak than mean intensity. Most of the 949 colonies were small and short-lived, but a small proportion were long-lived and reached 1000 aphids. Large colonies declined more slowly than moderately-sized colonies. Severe weather, shortening day-length, decline in host quality, density-dependent effects on rate of increase, and emigration failed to explain the population decline. An early rise and later decline in immigration, in conjunction with increasing predation through the summer, were consistent with the decline.

Abstract:
Long-term studies have revealed population declines in fishes, amphibians, reptiles, birds and mammals. In birds, and particularly amphibians, these declines are a global phenomenon whose causes are often unclear. Among reptiles, snakes are top predators and therefore a decline in their numbers may have serious consequences for the functioning of many ecosystems. Our results show that, of 17 snake populations (eight species) from the UK, France, Italy, Nigeria and Australia, 11 have declined sharply over the same relatively short period of time with five remaining stable and one showing signs of a marginal increase. Although the causes of these declines are currently unknown, we suspect that they are multi-faceted (such as habitat quality deterioration, prey availability), and with a common cause, e.g. global climate change, at their root.

Abstract:
Patterns in marine fish biodiversity can be assessed by quantifying temporal variation in rate of population change, abundance, life history and demography concomitant with long-term reductions in abundance. Based on data for 177 populations (62 species) from four north-temperate oceanic regions (Northeast Atlantic and Pacific, Northwest Atlantic, North mid-Atlantic), 81% of the populations in decline prior to 1992 experienced reductions in their rate of loss thereafter; species whose rate of population decline accelerated after 1992 were predominantly top predators such as Atlantic cod ( Gadus morhua ), sole ( Solea solea ) and pelagic sharks. Combining population data across regions and species, marine fish have declined 35% since 1978 and are currently less than 70% of recorded maxima; demersal species are generally at historic lows, pelagic species are generally stable or increasing in abundance. Declines by demersal species have been associated with substantive increases in pelagic species, a pattern consistent with the hypothesis that increases in the latter may be attributable to reduced predation mortality. There is a need to determine the consequences to population growth effected by the reductions in age (21%) and size (13%) at maturity and in mean age (5%) and size (18%) of spawners, concomitant with population decline. We conclude that reductions in the rate of population decline, in the absence of targets for population increase, will be insufficient to effect a recovery of marine fish biodiversity, and that great care must be exercised when interpreting multi-species patterns in abundance. Of fundamental importance is the need to explain the geographical, species-specific and habitat biases that pervade patterns of marine fish recovery and biodiversity.

Abstract:
Japan has experienced population decline since 2010 and the situation is expected to become more severe after 2030 with forecasts indicating an expected 30% decline from 2005 to 2055. Many other developed countries such as Germany and Korea are also experiencing depopulation. These demographic changes are expected to affect society at many levels such as labour markets decline, increased tax burden to sustain pension systems, and economic stagnation. Little is known however about the impacts of population decline on man-made physical infrastructure, such as possible deterioration of current infrastructure or increased financial burden of sustaining it. Infrastructure can be classified into 3 categories: point-type (e.g. buildings), point-network type (e.g. water supply) and network type (e.g. road). The impact of depopulation may vary according to the type of infrastructure. Previous research in this area has been limited in scope (e.g. case studies conducted in a single city focusing on a single type of infrastructure) and method (e.g. most research in the topic has been qualitative). This thesis presents a new comprehensive study on the impacts of population decline on infrastructure in Japan, taking into account all types of infrastructure and using a quantitative approach. Data collection methods include interviews and two large scale questionnaire surveys, the first conducted with municipalities and the second, a stated preference survey, conducted with members of the public. The goal of sustainable development is relevant even in a depopulated society, and hence a sustainable development framework is applied to the analysis where social, economic, environmental and engineering impacts are investigated. The main findings indicate that some infrastructure impacts observed and reported in depopulated areas do not seem to be related to any population decline; moreover, the preferences of citizens for infrastructure development is very similar between depopulated areas and non-depopulated areas. The results also suggest that the premises of Barro’s overlapping generations model, very relevant to a discussion of intergenerational decision making and related sustainability, appear to be rejected in this context.

Abstract:
Both in practice and theory, the focus in architecture is often largely about growth. Architecture is, therefore, a tool that we largely use to accommodate growth. However, whilst many cities are experiencing growth, many are facing population decline. Latvia’s capital Riga is one example of this. So while architecture often fixates on growth, the discourse on decline does not normally involve architecture. With this project, I sought to investigate the question: ‘How can we use architecture as a tool to accommodate decline?’ Through the study of an empty site in Riga, in an area which has lost 60% of its resident population since 2000, the project envisages a building designed to slowly consolidate the functions of a shrinking city over an extended time span.  The proposal, a ‘House of Everything’ (Latvian: Viskautkā Māja) is developed in two main ways. First, through a strategy for the site, delineating the rules and parameters for the anticipated building and its functions. Second, with a detailed test, using the strategy to develop a completed building.

Abstract:
Abstract Lion populations in West and Central Africa are small and fragmented. In areas where park management is weak, threats will likely facilitate the extinction of the lion. Wildlife management requires knowledge of the population estimate. The population of lions in Waza National Park (Waza NP) was assessed by individual identification of members in the population. The population was assessed to comprise of 14–21 adult individual lions. The age structure was skewed towards adults; cubs comprised 22% of all lions identified while the sex ratio was 1 : 3. Two out of four collared lions were lost to illegal, retaliatory killings within 1 year; and probably two more males and one more female were also killed during this period. The lion population appears to have declined during the last 5 years with six lions dying per year, which is at a much higher rate than observed in the previous decades. Human-livestock pressure has increased tremendously in this period, resulting to frequent human-lion conflicts. To ensure the survival of the lion in Waza NP and in the entire region, management needs to intensify efforts to mitigate the pressure from humans and their livestock.

Abstract:
The principal aim of the present study was to examine the longitudinal change in cognitive test performance in relation to major clinical CVDs and vascular risk factors in a population-based sample of older people. The analysis is based on a cohort of 809 men and 783 women aged 55-74 years which in 1987/8 was randomly selected from the general population of Edinburgh. The findings from the present study further add to those of previous investigations demonstrating a relationship between CVDs, vascular risk factors, and cognitive decline in older people. Specifically, they reveal that, even in the absence of overt stroke, clinical CVDs are associated with a greater cognitive decline in the elderly, independently of potential confounding by a wide range of vascular risk factors. Also, the relationships between several vascular risk factors and cognitive decline proved to be independent of co-existing vascular pathology. Based on these findings, further study is needed to determine the combined effects of CVDs and multiple risk factors on cognitive outcomes in samples of older people. In addition, what the likely pathological mechanisms are underlying cognitive decline associated with atherosclerotic disease and vascular risk factors risk factors needs to be addressed in future studies. From a perspective of preventing or delaying vascular-based cognitive decline and impairment, more research is required to assess the effectiveness of both individual and population-based strategies targeting vascular disease and risk factors in older age groups. Finally, further investigation is needed to address the potential impact of subtle cognitive deficits on indictors of the quality of life and the capability of self-maintenance of elderly vascular patients, on adherence to medical treatment and rehabilitation, and further cognitive decrements and survival.

Abstract:
The aim of the study is to investigate the current state of awareness of urban shrinkage inLiepājaby the key actors involved in the planning process. Last couple of hundred years have brought many transformations in urbanity that was always accompanied by the growth of the population and expansion of the city. However, the new patterns of urban development emerged in the last decades all over the globe, causing cities to lose the inhabitants resulting in urban shrinkage.Liepāja, the third largest city inLatvia, has lost a quarter of its population in last two decades and the trend continues. The long-term municipal planning document is being presented during this research in a light of which the research question is asked: “What is the current state of awareness of urban shrinkage inLiepājaby the key actors?” Utilising Flyvbjerg’s phronetic form of inquiry in combination with case study and repeated semi-structured interviews, the dominant planning views related to urban shrinkage are sought and analysed. The research identifies three underlying causalities that shape the decisions in planning and leave formidable consequences for the future of the city. The causalities identified and discussed in this paper are (1) the planning legacy; (2) the misconception; and (3) the political sensitivity of the urban shrinkage.

Abstract:
Background: The major complaints of the elderly are hearing and memory loss, which have a devastating impact on the communication process. Previous studies have shown that hearing loss is associated with the acceleration of this cognitive decline. Objectives: To analyze the relationship between moderate to moderatelysevere hearing loss and memory deficit in elderly individuals. Design and setting: This is an observational, cross-sectional study realized in seniors of Hearing Care Program at the Taubaté University Hospital, Taubaté - SP/ Brazil. Methods: Data was collected using audiometry, anamnesis, and the cognition test Mini Mental State Examination (MMSE) in 60-75 years old individuals, without knowledge of previous cognitive memory deficit and without the use of hearing aids. Results: Between the 61 seniors interviewed, 68% had moderate degree of deafness and 32% moderately severe degree. Among the normal results in the MMSE, 24% had moderately severe deafness; of those with cognitive impairment without indication of investigation of dementia, 35.7% had moderately severe deafness, and of those with indication of investigation of dementia, 50% had moderately severe deafness. In addition, 23% of the total sample had results in the normal cutoff range, showing the tendency for cognitive decline in this population. Conclusions: these data indicate a progression in the proportion of individuals with a higher degree of hearing loss, the higher the cognitive deficit.

Abstract:
The comparative analysis of birth rate and life expectancy will provide information about the position of Macedonia in relation to Turkey and the EU and also about the factors that have the greatest impact on the population’s movement and vitality. This information should help the policy creators in the process of defining and implementing measures for increasing the birth rate and life expectancy of the population, which is aim of every country. In this paper will be put out some theoretical aspects about the economic, social, psychological, technological, cultural and political factors that have impact on the birth rate and life expectancy of the population. Also, the tabular and graphical displays will show the movement of these two demographic features in the period from 1980 to 2011. Changes in birth rate and life expectancy in Macedonia, Turkey and the European Union have been leading to demographic aging of the population in the last three decades. The birth rate in these countries shows a trend of continuous decline, despite the gradual increase in life expectancy of the population. Although the declined birth rate and increased life expectancy of the population have been a common features of these countries in the last decades, the percentage of this changes is different for each country.

Abstract:
Background: We observe Subjective Cognitive Decline (SCD) when patients perceive a decline in their cognitive functions, but this decline is not detected in neuropsychological assessments. Few studies have investigated the prevalence of SCD in the Brazilian population. Objective: Analyze the profile of 50+ years Brazilian people regarding SCD through a self-administered online questionnaire Methods: Cross-sectional study, in the online modality. The recruitment of participants took place through email, Facebook, and WhatsApp. Results: We received 1440 responses, mainly from the country’s Southeast region (80.0%). Most of the respondents were female (67.0%), with a mean age of 58.7 (SD=8.5) years, heterosexual (97.3%), skin color referred to as white (84.5%), married (67.6%), post-graduated (51.0%) and working, but not retired (45.5%). About 55.0% reported that their memory has worsened over the past five years and 50.0% of those informed that the worsening of memory worries them. For 38.0% of the respondents, their memory is adequate. Regarding cognitive functions in the last five years, 41.0% claim that they have had problems with attention or concentration, 46.0% that their reasoning has slowed down, and 55% that they have had issues with language. Conclusion: An expressive proportion of the analyzed sample perceived a decline in their cognition at some level.

Full text
Abstract:
India, the second most populous country in the world, experienced an accelerated decline in fertility during the 1980s. As a result, India’s total fertility rate (TFR) in 1993, 3.5 births per woman, is below the level presumed in the population projections of the United Nations and the World Bank. This favorable development has occurred as India is attempting to reorient its family planning program to focus on the reproductive health of women and the health and welfare of children. The method-specific targets for contraceptive acceptors assigned to every grassroots health worker were abandoned in April 1996. Against this backdrop, this paper seeks to analyze the components of future population growth in India based on a series of hypothetical projections using alternative assumptions about the future decline in fertility. Only one assumption is made about the pace of mortality decline. The likely consequences of the prospective population growth and the policy options for accelerating fertility decline are also discussed.

Full text
Abstract:
From 16 years (2005–2020) of monitoring trends in white-tailed deer within a defined survey area of Arkansas Post National Memorial, we have been able to demonstrate both population declines and recoveries. The adjusted count of deer had a seven-fold increase between 2007 and 2011 following a two-year decline and a three-fold increase between 2017 and 2019 following a six-year decline. Overall, the deer population has declined slightly, averaging a 0.5% reduction in herd size annually. The number of deer in the survey area ranged from 16.77 ± 21.26 (mean + 95% CI) individuals/km2 in 2007 to 118.95 ± 39.03 individuals/km2 in 2011. The amount of visible area surveyed each year varied between 0.25 and 0.47 km2 (coefficient of variation = 16.47%). If the white-tailed deer population becomes too large, this poses several problems for Arkansas Post National Memorial. First, it adds a level of complexity to implementing active natural resource management critical to preventing the cultural landscapes of Arkansas Post National Memorial from changing into something that has little resemblance to the historical character of the park. Deer deferentially browse native vegetation over exotic vegetation, thus promoting the spread of exotic species, and the success of tree planting can be curtailed by heavy deer browsing. Second, controlling deer related disease, some of which can affect domestic livestock and human health in and around the park, becomes increasingly difficult when there are more deer. Third, as additional ancillary data suggests, the largely unreported and costly deer-vehicle collisions in and around Arkansas Post National Memorial have the potential to increase if the deer populations grow.

Abstract:
SUMMARY OF FIELD OPERATIONS Over the past year, fieldwork resumed at pre-pandemic levels. In February 2022, the wolf population was likely comprised of 28 wolves. This is an increase from the next most recent estimate of 12-14 wolves, made 24 months earlier in March 2020 (Fig. 1). The wolf population appears to be primarily organized as two main socia groups—an eastern pack consisting of at least 13 wolves and a western pack most likel consisting of 13 wolves—and two wolves that may not be part of either pack. There is evidence that pups were born to both packs in April 2021. For context, there is also evidence that one litter of pup was born in 2019 and two litters were born in 2020. Wolves appear to be an important cause of mortality for moose once again. In particular, this past year, the proportion of the moose population killed by wolves (i.e., the predation rate) was 8.7 percent. That rate is almost twice as high as the predation rate observed in 2020 (4.5 percent) and it is the highest predation rate observed since 2011. Overall, the new population of wolves on Isle Royale appear to be well-established and functioning healthily. Over the past year, the U.S. National Park Service (NPS) continued its efforts to outfit a small proportion of the wolf population with GPS radio collars to help monitor the recovering population. The estimated abundance of moose declined by 28 percent, from 1,876 to 1,346, between February 2020 and February 2022. Longer-term population trends suggest that the moose population had increased greatly over an eight-year period (2011-2019) but then started to decline over the last few years. The decline in moose abundance is likely a consequence of several factors, including higher predation rates by wolves, severe burdens of parasites (winter ticks), and a shortage of winter forage, indicated in part by an unusually high number of moose dying from malnutrition over the past two years. That shortage of winter forage, specifically balsam fir, is likely due to a combination of intense browsing by moose in previous years and recent defoliation due to budworm (moth larvae) in some regions of the park. In February 2022, 19 moose were outfitted with GPS collars so their movements and behavior can be monitored, adding to the 45 moose radio-collared between 2019 and 2020.
