Abstract:
The economies of Africa’s largest metropolitan regions reflect a contested intersection of orientations, practices, demands, values, and articulations to the larger world. While rural to urban migration may have substantially decreased, the circulation of populations within metropolitan regions, across primary and secondary cities, and along increasingly elaborated transnational circuits of movement and exchange raise important questions about conventional notions of population movement. As planning mechanisms tend to assume certain stability in the relationship of population to place, what kinds of understanding of movements may be necessary to engage the variegated ways that cities are articulated through these movements?

Abstract:
Both genetic cohesion among local populations of animals and range expansion depend on the frequency of dispersers moving at an interpatch scale. Animal movement has an individual component that reflects behaviour and an ecological component that reflects the spatial organization of populations. The total movement capacity of an individual describes maximum movement distance theoretically achievable during a lifetime, whereas its variation among the members of a local population determines the magnitude of interpatch movements and thus of gene flow between neighbouring patches within metapopulation or patchy population systems. Here, I review information on dispersal and migration as components of the movement capacity of juvenile and adult pond-breeding amphibians and discuss how these components inform the spatial structure of populations. Amphibians disperse as juveniles and adults, but movement distances detected in tracking or capture–mark–recapture studies are usually far below the corresponding estimates based on molecular gene-flow data. This discrepancy reflects the constraints of available tracking methods for free-ranging individuals leading to inappropriate surrogates of annual movement capacity, but can be resolved using probabilistic approaches based on dispersal functions. There is remarkable capacity for and plasticity in movements in amphibians. Annual within-patch movements (migrations) of individuals can be large and likely represent an underestimated capacity for movement at the interpatch scale. Landscape resistance may influence the paths of dispersing amphibians, but rarely impedes interpatch movements. Juveniles emigrating unpredictably far from the natal pond and adults switching from within-patch migrations to dispersal to another patch demonstrate the plasticity of individual movement behaviour. Three basic conclusions can be drawn with respect to the linkage of individual movement behaviour and spatial or genetic structure of local amphibian populations embedded in a heterogeneous landscape: (1) individual movements or consecutive short-term series of movements are misleading surrogate measures of total movement capacity; (2) probabilistic modelling of movement capacity is the best available behavioural predictor of interpatch gene flow; (3) connectivity of local populations in heterogeneous landscapes is less affected by landscape resistance than previously expected.

Abstract:
Especially in recent years, important population mobility occurs worldwide, including refugee crisis affecting especially Middle East and Europe. Consequently, like other infectious diseases have significance for public health, leishmaniasis is spreading globally. 350 million people in 88 countries, mostly in developing areas, are at risk of leishmaniasis. The diseases may be seen in three clinical forms as cutaneous, mucocutaneous, or visceral caused by about 20 different species of Leishmania parasite. The parasitological diagnosis is made by microscopic examination, cultivation, PCR and serological methods. There is currently no available vaccine for this infection. Pentavalent antimonials are the first line therapeutic choice, whereas amphotericin B, pentamidine, miltefosine, and paromomycin are alternative drugs. Other side, increasing resistance and toxicity of the current therapeutics are significant problems. The combination therapy, immunotherapy, anti-leishmanial synthetic and natural products, and local hyperthermic applications are promising for future treatment of leishmaniasis. The preventive efforts have been applying based on individuals and community.In CHB patients, habits of drinking alcohol and cigarette smoking, elevated serum levels of TBil and serum AST/ALT ratio, increased duration of hepatitis B, a family of hepatitis B, male gender and older age can increase the risk of LC development.

Abstract:
AbstractA fast-timescale approximation is applied to the coalescent process in a single population, which is demographically structured by sex and/or age. This provides a general expression for the probability that a pair of alleles sampled from the population coalesce in the previous time interval. The effective population size is defined as the reciprocal of twice the product of generation time and the coalescence probability. Biologically explicit formulas for effective population size with discrete generations and separate sexes are derived for a variety of different modes of inheritance. The method is also applied to a nuclear gene in a population of partially self-fertilizing hermaphrodites. The effects of population subdivision on a demographically structured population are analyzed, using a matrix of net rates of movement of genes between different local populations. This involves weighting the migration probabilities of individuals of a given age/sex class by the contribution of this class to the leading left eigenvector of the matrix describing the movements of genes between age/sex classes. The effects of sex-specific migration and nonrandom distributions of offspring number on levels of genetic variability and among-population differentiation are described for different modes of inheritance in an island model. Data on DNA sequence variability in human and plant populations are discussed in the light of the results.

Abstract:
This article examines the retrospective dynamics of the natural movement of the population of the Russian Federation from the perspective of achieving demographic security of the country. The purpose of the work is to analyze the indicator of natural population growth/decline through economic demography and social demography to identify the impact of socio-economic conditions on demographic processes and the impact of demographic factors of changes in the natural movement of the population on socio-economic dynamics. To achieve this goal, Family and Demography Center of the Tatarstan Academy of Sciences, with the direct participation of the authors, conducted a monitoring study of demographic processes (natural population growth/ decline, fertility and mortality) for the period from 2000 to 2020 within the framework of the preparation of the Demographic Report-2021 "Retrospectives and prospects of reproduction of the population of the Republic of Tatarstan (2000-2020)", which made it possible to analyze the dynamics of these demographic processes. The Russian Federation is in a demographic crisis, which is characterized by depopulation, when mortality exceeds fertility, which is especially aggravated due to the spread of the COV1D-19. Changes in the natural movement of the population are largely determined by changes in the sex and age structure of the population: a decrease in the number of women of reproductive age, increased mortality of men of working age, aging of the population. 1n the course of work on the article, the results of the sociological study "Demographic Well-Being of Russia", conducted in 2020 with the participation of the authors of the article, as well as regression and correlation analysis were used to identify the relationship between variables. The results obtained indicate the relationship between natural population decline and economic processes. The negative consequences are connected with a reduction in the labor force, aging of the population, deterioration of public health, etc. The results of the study are of practical value for the development of an effective demographic policy of the Russia.

Abstract:
Abstract:Wild turkey (Meleagris gallopavo) studies have traditionally focused on factors associated with population change from within the population. Consequently, movement into and out of turkey populations is poorly understood. From 2000–2002, we monitored 554 Rio Grande wild turkeys (M. g. intermedia) at 3 sites in the Texas Panhandle to determine the pattern, prevalence, composition and importance of movements among winter roosts. The majority (85.6%) of all monitored birds exhibited winter range fidelity. Differences among age and sex classes existed. Adult females exhibited the highest winter range fidelity (96.7%), while yearling females exhibited the lowest (62.5%). Further, yearling females were responsible for the majority of permanent movements away from winter roosts (dispersal). For both residents and dispersers, winter was the season of least movement, while dispersers exhibited the greatest movement during spring. We found no evidence of decreased survival or productivity between yearling dispersers and yearling residents. Our findings suggest yearling females may play an important role in connecting relatively disjunct winter roost populations.

Abstract:
Movement of organisms is an important mechanism controlling an array of processes within ecosystems. Recent analyses suggest that movement is composed of individual displacement (distance moved by individuals) and turnover (proportion of individuals moving). Turnover of individuals is important because it influences population size and structure, as well as interactions among individuals and different species within a habitat. We used stationary antennas and passive integrated transponders tags to monitor individual habitat use, turnover, and displacement of Sonora suckers (Catostomus insignis) and desert suckers (Catostomus clarkii) in the West Fork Gila River, New Mexico, USA. Many tagged fish used our focal stationary antenna reach, but only a subset was consistently present. Population size and turnover rates were variable from day to day. Although some individuals spent the majority of their time within the focal reach, most made extended departures (one or more days) from their home pools. Many individuals displayed fidelity to a particular habitat despite forays elsewhere, returning to the focal reach throughout the study. Diel or short-term movements may explain high turnover rates typically observed and, combined with high site fidelity, may result in the misclassification of individuals as sedentary, despite frequent, potentially short-term, movements into other habitats.

Abstract:
Population-level analyses of SMOs typically have relied on a single source for data, most commonly the Encyclopedia of Associations (EoA). However, the validity of this procedure has been drawn into question by recent organizational studies. To examine the impact of using different sources to estimate SMO populations, we compile a comprehensive population dataset of national and regional U.S. environmental movement organizations (or EMOs) over a 100-year time period using 155 different sources. We use this data to evaluate the accuracy and selection biases in five major compilations of U.S. EMOs. The analysis shows that all single sources are selective, tapping specific sections of the environmental movement. Multiple sources are needed to capture a comprehensive population of EMOs. Researchers should be aware of the limitations of specific sources before drawing conclusions about population parameters.

Full text
Abstract:
Sauger Sander canadensis are a native top level predator and popular sport fish. They are native to large, turbid midwestern rivers and are a highly migratory species that relies on unrestricted access to specific habitats throughout their lifespan. Due to specific habitat requirements and popularity as a sport fish, Sauger are in decline across much of their range. Habitat alterations including barriers, channelization and sedimentation, as well as overharvest, have resulted in population declines. Sauger are often subject to relatively high levels of exploitation because of their tendency to concentrate below dams during migrations, which leaves them vulnerable to anglers. The lower Kaskaskia River below Carlyle Lake dam and the lower Ohio River contain important Sauger sport fisheries despite the presence of multiple dams on both rivers and the potential for high levels of exploitation. However, effects of current and potential harvest regulations on Sauger stocks in the Kaskaskia and Ohio rivers have not been assessed. From previous annual monitoring surveys, Sauger in the Ohio and Kaskaskia rivers have very different size and age structures and are managed under different regulations. Additionally, the Kaskaskia River and its largest reservoir (Carlyle Lake) are stocked annually with Sauger, but the contributions of stocked Sauger and immigrants from the Mississippi River to the Kaskaskia River Sauger stock are unknown. I first sought to assess population demographics of Sauger in the Kaskaskia and Ohio Rivers to gain a baseline understanding of both populations and then used these data to evaluate harvest regulations on each river. This objective tested the null hypothesis that no differences in recruitment indices, growth rates and mortality rates exist between Sauger populations within each river. Sauger in the Kaskaskia River are currently managed under a 356-mm minimum length limit and a 6-fish daily bag limit. Prior to 2018, the lower Ohio River was managed under no minimum length limit and a 10-fish daily bag limit. To assess the contribution of Sauger from different environments to the Kaskaskia River stock, I used otolith microchemistry to infer recruitment sources of fish and assess movement of fish between the Kaskaskia and middle Mississippi rivers. This objective tested the null hypothesis that no difference existed in the contribution of different rivers to the Kaskaskia River sauger population. The Ohio River Sauger population had a small age and size structure relative to the Kaskaskia River. Sauger from each river exhibited fast growth rates and high annual mortality. Population modeling indicated that the current 356-mm minimum size limit for Sauger in the Kaskaskia River is sufficient at preventing growth overfishing and is likely resulting in the larger size structure compared to the Ohio River. Sauger were likely experiencing growth and recruitment overfishing in the Ohio River under no minimum length limit and will likely benefit from the 356-mm minimum length limit implemented in 2018. Otolith microchemistry revealed that Sauger from the Mississippi River represented a small contribution to the Kaskaskia River Sauger stock; however, some fish showed evidence of moving between the Kaskaskia and Mississippi rivers. Similar water chemistry between the hatchery and Carlyle Lake prevented the identification of hatchery origin Sauger. Because the Sauger stock in the Kaskaskia River appears to be primarily supported by stocking of fish into Carlyle Lake or natural reproduction within the Kaskaskia River, fisheries managers should focus on quantifying the contribution of hatchery fish to the Kaskaskia River stock.

Abstract:
This research investigated the effects of coordinating rodent control across areas up to 400 ha, using conventional and alternative strategies, to see if it was possible to reduce rat numbers and to keep them at a lower level compared with uncoordinated control. The aims were to reduce the rat numbers, reduce the amount of rodenticide used over time and to reduce the risk of secondary poisoning of non-target animals. Rodenticide loads in rat carcasses were investigated using historical and new samples from Berkshire, Leicestershire and Yorkshire in order to quantify risk to non-target predators of rats. Movement was also studied to see if rats were moving into farmyards in the autumn and out in the spring as is generally assumed. Analysis of radio-tracking data showed that the majority of rats tracked stayed within a small home range, two moved and stayed away from the trap site and only one moved into a farmyard. Analysis of the movement of the rats caught in traps showed that the movement towards and away from farms was in roughly equal numbers. The rodenticide analysis showed that rats from areas of rodenticide resistance carried a far greater body load of poison than those from non-resistance areas. Thus resistance increases the risk of a predator or scavenger of rats ingesting a lethal dose more quickly in areas of rodenticide resistance. The coordinated rat control was broadly successful over a period of two to three years. Rat numbers varied greatly between Yorkshire and Leicestershire, with Yorkshire having the larger numbers. Rat control in the coordinated areas showed a decreasing trend over the period. Bait take also generally showed a decline over the period. The results revealed an apparent delayed synchrony in rat numbers between coordinated and uncoordinated areas in Yorkshire that requires further investigation to explain.

Abstract:
Sharks are particularly vulnerable to over-exploitation. Although catsharks are an important component of the near-shore marine biodiversity in South Africa and most of the species are endemic, little is known about their movement patterns, home range and population size. With an increasing number of recreational fishers this information is crucial for their conservation. The aims of this study were threefold. Firstly, to identify and analyze existing data sources on movement patterns and population dynamics for four catshark species: pyjama (Poroderma africanum), leopard (P. pantherinum), puffadder (Haploblepharus edwarsii) and brown (H. fuscus). This highlighted a number of shortcomings with existing data sets, largely because these studies had diverse objectives and were not aimed solely at catsharks. Secondly, a dedicated study was carried out for a limited area, testing a number of methods for data collection, and where appropriate the data was analyzed to determine movement patterns and population numbers. Thirdly, the most appropriate methodology for future studies (with similar objectives) was identified, and the results of the study were used to propose a number of conservation measures. All species of catsharks exhibited strong site fidelity and limited dispersal for extended periods. A few individuals did, however, travel distances in excess of 150 km. Significant trends in temporal abundance were not observed, nevertheless, there was some evidence for higher catches from September to December. Population estimates for the study area were low, with P. africanum having the smallest population size while H. fuscus had the highest population size within the restricted study area. Limited movements, high site fidelity and small population sizes emphasize their vulnerability and suggest that catsharks would benefit from no-take marine protected areas.

Abstract:
Spawning flannelmouth sucker, Catostomus latipinnis, in the Paria River averaged 478 mm (n = 246) total length (TL). This was 53 mm longer (p < 0.001) than the mean length of spawning fish taken from this same location in 1981 (425 mm, TL, n = 286). Sub adult flannelmouth were common in the Paria in 1981 but no post-larval fish < 379 mm, TL were caught in 1992 or 1993. There is no evidence that juvenile flannelmouth have reared in the Paria River/Glen Canyon Area in the last 12 years. However, some adult fish appear to enter the population from downstream locations. In 1992 and 1993, spawning occurred throughout the lower 10 kilometers of the Paria. Young-of-year were seen in 1992 but could not be found shortly after hatching. No young-of-year were seen in 1993. Growth of adult sized fish is very slow. Based on extrapolations from recaptures, longevity may approach 30 years. Recaptures from fish marked in other studies were originally tagged as far as 229 km downstream from the mouth of the Paria.

Abstract:
Estimations on people movement behaviour within a country can provide valuable information to government strategic resource plannings. In this paper, we propose to utilize multi-domain statistical data to estimate people movements under the assumption that most population tend to move to areas with similar or better living conditions. We design a Multi-domain Matrix Factorization (MdMF) model to discover the underlying consistency patterns from these cross-domain data and estimate the movement trends using the proposed model. This research can provide important theoretical support to government and agencies in strategic resource planning and investments.

Abstract:
In the past 50 years, the population of Montenegro has undergone all phases of natural population movement, which is characteristic of accelerated demographic transition. In the early 1960s, birth rates were high, but after the 1970s, they shifted to moderate levels. At the beginning of this century, birth rates in Montenegro were at the upper limit of low levels. In contrast, mortality rates increased due to the aging of the population, transitioning from low to moderate levels. The moderate increase in mortality rates is also a normal consequence of population aging. The beginning of the 21st century was marked by inherited declining fertility rates from the end of the 20th century, with a tendency to decrease birth rates throughout Montenegro, but with pronounced regional differences. Essentially, behind the regional differences lie predominantly unequal regional development, influenced by factors such as tradition and religion. This has led to migration flows towards the capital and the Southern region. With the departure of young people, these areas are left without a demographic base for population reproduction, while, at the same time, the population potential of immigration municipalities increases. As a result of these movements, almost all municipalities in the Northern region have experienced low and negative natural population growth rates in the last 20 years, as have municipalities in the Central region, except for Podgorica. The situation in municipalities in the Southern region is somewhat different. The natural population movement in Montenegro has entered a phase where there is a need to focus on biodynamic rejuvenation, i.e., increasing birth rates if we want to avoid a situation similar to that faced by many European countries and our immediate surroundings, where negative natural population growth rates result in population decline. Adding to this fact is the emigration of a certain portion of the population beyond the state borders. It is clear that measures must be taken to increase natural population renewal.

Herrera, Cristian. What is the impact of policies for managing the movement of health workers between public and private organizations? SUPPORT, 2017. http://dx.doi.org/10.30846/1705142.

Full text
Abstract:
Health workers move between public and private organizations in both urban and rural areas during the course of their career. This can result in imbalances in the number of healthcare providers available relative to the population receiving care from that sector. Different financial incentives and movement restriction interventions may manage this issue in low income countries.

Abstract:
Many animal species form congregations on the landscape. These concentrations of animals provide an opportunity for biologists to conduct efficient population monitoring efforts. While general use of these sites is easy to document, continual monitoring is often problematic due to limited resources (time, expertise, etc.), potential for human disturbance on animal population and behavior, and an inability to determine an accurate assessment of counts. To allow for accurate and efficient assessment of animal numbers and usage of an area, an automated technology has been developed to monitor and characterize large animal concentrations. This automated technology provides information on population size, movement behavior characteristics, and other behavioral aspects of the target species.

Abstract:
Accurate and reliable health information is a cornerstone of effective public health. Conversely, there is a growing body of evidence demonstrating that misinformation, misconceptions and myths spread fast and have substantial negative impacts on population health, such as by reducing confidence in vaccines or promoting unproven cancer treatments. In light of this, the global movement to eliminate cervical cancer needs to recognise and integrate measures to dispel myths, misconceptions and misinformation surrounding cervical cancer.

Full text
Abstract:
This study investigates the impact of wolf reintroduction on wildlife-vehicle collisions (WVCs) along a segment of US-191 bordering Yellowstone National Park. Wolves were reintroduced in 1995–1996, and subsequent wolf pack establishment may have influenced the behavior and population dynamics of prey species, potentially altering WVC patterns. Using carcass data collected from 1989 to 2021, the analysis was divided into two primary phases: before wolves (1989–1996) and after wolves (1997–2021). A series of linear mixed-effects models were developed to assess changes in WVCs across these time periods. Predictor variables included average annual daily traffic (AADT), elk population estimates, and wolf counts. Results showed that WVCs significantly declined in the post-wolf period, suggesting that the presence of wolves may reduce WVCs directly by modifying prey behavior and movement patterns, or indirectly by reducing prey population densities. Further analysis revealed that while elk populations were a significant predictor of WVCs before wolves were reintroduced, this relationship weakened post-reintroduction. Traffic volume did not significantly influence WVC patterns in either period, nor did it interact significantly with wolf presence. The inclusion of wolf counts as a continuous variable showed a negative relationship with WVCs, indicating that higher wolf densities may contribute to a further reduction in collisions over time. These findings suggest that apex predators can play a role in mitigating human-wildlife conflicts, such as WVCs, by influencing prey species’ behavior and distribution. The study provides valuable insights for wildlife managers and transportation planners, highlighting the potential benefits of predator conservation for road safety and ecosystem health.

Full text
Abstract:
The Great Green Wall for the Sahara and the Sahel Initiative (GGWI), launched in 2007 by the African Union, is one of Africa’s most important green transformation projects. From a pan-African environmental movement to a mosaic of locally managed projects to its considerable funding from the international community, the GGWI is now seen as a ‘megaproject’. While this megaproject has been primarily studied along the lines of political ecology and critical development studies, both showing the material limits and effectiveness of the initiative, its impact on the ground remains important in that the Sahelian landscape is shaped by donor and development actors’ discourses and imaginaries. The conceptual debates around the notion of ‘future’ thus make it possible to capture and facilitate the emergence of endogenous practices and environmental knowledge which involve the population, their history, and their culture using specific methods. By implementing the relationship formulated by Jacques Lacan between symbolic, reality and imaginary, this project will make it possible to approach the GGWI project as a social-technical imaginary while considering the complex social-ecological processes that this project involves.

Avis, William. Refugee and Mixed Migration Displacement from Afghanistan. Institute of Development Studies (IDS), 2021. http://dx.doi.org/10.19088/k4d.2022.002.

Full text
Abstract:
This rapid literature review summarises evidence and key lessons that exist regarding previous refugee and mixed migration displacement from Afghanistan to surrounding countries. The review identified a diverse literature that explored past refugee and mixed migration, with a range of quantitative and qualitative studies identified. A complex and fluid picture is presented with waves of mixed migration (both outflow and inflow) associated with key events including the: Soviet–Afghan War (1979–1989); Afghan Civil War (1992–96); Taliban Rule (1996–2001); War in Afghanistan (2001–2021). A contextual picture emerges of Afghans having a long history of using mobility as a survival strategy or as social, economic and political insurance for improving livelihoods or to escape conflict and natural disasters. Whilst violence has been a principal driver of population movements among Afghans, it is not the only cause. Migration has also been associated with natural disasters (primarily drought) which is considered a particular issue across much of the country – this is associated primarily with internal displacement. Further to this, COVID-19 is impacting upon and prompting migration to and from Afghanistan. Data on refugee and mixed migration movement is diverse and at times contradictory given the fluidity and the blurring of boundaries between types of movements. Various estimates exist for numbers of Afghanistan refugees globally. It is also important to note that migratory flows are often fluid involving settlement in neighbouring countries, return to Afghanistan. In many countries, Afghani migrants and refugees face uncertain political situations and have, in recent years, been ‘coerced’ into returning to Afghanistan with much discussion of a ‘return bias’ being evident in official policies. The literature identified in this report (a mix of academic, humanitarian agency and NGO) is predominantly focused on Pakistan and Iran with a less established evidence base on the scale of Afghan refugee and migrant communities in other countries in the region. . Whilst conflict has been a primary driver of displacement, it has intersected with drought conditions and poor adherence to COVID-19 mitigation protocols. Past efforts to address displacement internationally have affirmed return as the primary objective in relation to durable solutions; practically, efforts promoted improved programming interventions towards creating conditions for sustainable return and achieving improved reintegration prospects for those already returned to Afghanistan.

Full text
Abstract:
Endophytes were isolated from 16.7% of surface-disinfested seeds and 100% of stems and roots of field-growth plants. Strains from Israel with broad-spectrum in vitro antibiosis were mainly Bacillus spp., and some were chitinolytic. Following dipping of cut cotton roots into suspensions of these strains, endophytes were detected up to 72 days later by isolation and by autoradiograms of 14C-labelled bacteria. Selected endophytes exhibited biological control potential based on significant reductions in disease severity on cotton inoculated with Rhizoctonia solani or Fusarium oxysporum f. sp. vasinfectum as well as control of Sclerotium rolfsii on bean. Neither salicylic acid nor chitinase levels increased in plants as a result of endophytic colonization, suggesting that the observed biocontrol was not accounted for by PR protein production. Some biocontrol endophytes secreted chitinolytic enzymes. Model endophytic strains inoculated into cotton stems via stem injection showed only limited movement within the stem. When introduced into stems at low concentrations, endophytes increased in population density at the injection site. After examining several experimental and semi-practical inoculation systems, seed treatment was selected as an efficient way to reintroduce most endophytes into plants.
