Abstract:

Context. The wild rabbit (Oryctolagus cuniculus) is a keystone species from the Iberian Peninsula that has suffered a strong decline in Spain during the past decades. Data on historical and current population trends in Portugal are virtually non-existent. Aims. To investigate changes in rabbit abundance at the national level so as to inform conservation status assessments, and to evaluate the usefulness of hunting bags as a rabbit abundance index. Methods. Field surveys based on latrine counts in linear transects were performed in two periods (1995 and 2002) to assess variation in population abundance. Hunting bags were also analysed for the same period to verify whether these data showed the same trends. General trends of rabbit abundance were estimated using TRIM software. Key results. Field data revealed that most of the sampling units across Portugal have low abundances, despite the observation of local high-density spots. A population reduction of 27% was estimated. Although some fluctuations were observed in hunting bags, global results obtained from these data suggest a slightly increasing trend in rabbit abundance. Conclusions. A discrepancy between field data and hunting statistics was observed. Because hunting bags may be influenced by sporadic management operations undertaken by hunters and the lack of systematic procedures in data collection, we believe that hunting statistics are not representative of real changes in rabbit populations. Thus, observed reduction in rabbit abundance estimated by field data, combined with the high initial morbidity due to rabbit haemorrhagic disease (RHD) after 1988 and the potential for continuing decline in population trends because of other factors, led to an inference of a reduction of >30% in rabbit abundance in Portugal during the past decade. Implications. Taking into account the estimated reduction, the species’ biology and socioeconomic implications, wild rabbit in Portugal was listed in 2005 in the Near Threatened category under IUCN criteria. Because of its ecological and economic importance, this classification prompted the definition of several conservation actions aimed at the recovery of the species in Portugal.

Abstract:

The multi-agent collaborative hunting problem is a typical problem in multi-agent coordination and collaboration research. Aiming at the multi-agent hunting problem with learning ability, a collaborative hunt method based on game theory and Q-learning is proposed. Firstly, a cooperative hunting team is established and a game model of cooperative hunting is built. Secondly, through the learning of the escaper’s strategy choice, the trajectory of the escaper’s limited T-step cumulative reward is established, and the trajectory is adjusted to the hunter’s strategy set. Finally, the Nash equilibrium solution is obtained by solving the cooperative hunt game, and each hunter executes the equilibrium strategy to complete the hunt task. C# simulation experiment shows that under the same conditions, this method can effectively solve the hunting problem of a single runaway with learning ability in the obstacle environment, and the comparative analysis of experimental data shows that the efficiency of this method is better than other methods.

Abstract:

In Finland, hunting bounties for pest animals were first introduced in the 1647 hunting law. Avian pests were included in bounty schemes a century later when a price was put on more than 20 species. The list of bounty species varied widely during the next 200 years. We examined the development of bounty schemes in Finnish wildlife management during 1647–1975 with respect to the prevailing attitudes to nature and hunting practices. We surveyed Finnish hunting legislation from the 1300s to the present, and collected hunting bounty data from hunting associations' archives and from statistics published in hunting magazines during the 19th and 20th centuries. Local municipalities and the government, and also hunters' and fishermen's organizations, paid bounties for pest species. Bounties were considered justified for direct and indirect economic, religious and ethical reasons. Organized persecution of pests was considered a necessary component of game management. The ‘golden age’ of bounty schemes from 1898 to the 1920s contributed to local extinctions of both mammalian and avian species. The cessation of law-based bounty schemes in 1975 was preceded by a period of strong environmental thinking, and bounty schemes were widely considered costly, outdated and unethical.

Abstract:

Population trends, numbers of harvested adult females and harvest rates of red deer (Cervus elaphus) in Switzerland and in the canton of St. Gallen were analysed using freely accessible data from federal and regional hunting statistics. We did the same analyses with data from chamois (Rupicapra rupicapra) in Switzerland and in the cantons of Berne and St. Gallen. Data from roe deer (Capreolus capreolus) were analysed for Switzerland and the cantons of Solothurn and Vaud. The results show that the new Swiss hunting and forest laws have not had any effect on population size of red deer, chamois and roe deer yet. Regulative effects, however, could be shown locally for the red deer in the canton of St. Gallen and for the chamois in the cantons of Berne and St. Gallen. There is evidence that the present hunting statistics represent only an incomplete base for comprehensive harvest planning according to the law.

Abstract:

The study was conducted to assess hunting activities in Ido Local Government Area, Oyo State, Nigeria. A well-structured questionnaire was administered to obtain information from fifty hunters using a simple random sampling technique. Data were analyzed using descriptive statistics. The result showed that 96% of hunters in the study area were men. Most of the respondents were married (84%) and within the age bracket of 31 and 50 years (48%). About 34% and 40% of respondents had primary and secondary education respectively while 13% had no formal education. They had between 20 and 29 years’ experience in wild animal hunting. Sixty-eight percent of the hunters in the study area engaged in part-time hunting while 32% were full-time hunters. The study further revealed that the hunters engaged in hunting for financial gain (64%), leisure (34%) and family tradition (38%). About ten types of species of wildlife animals were commonly killed by the hunters, and the animals were sold within the community market (42%), outside the community market (32%) and to visiting bushmeat marketers (26%). The study therefore recommends a policy that will control hunting activitiesin the study area, knowing that animal hunting serves as another source of livelihood to the hunters.

Abstract:

SummaryThe European Commission’s 1979 Wild Birds Directive bans member states from hunting wild birds during spring, the period during which they are breeding or migrating, as hunting wild birds before they have reproduced is perceived to have a greater effect on bird populations than it would in autumn or winter. Malta is the only European Union member state to allow recreational wild bird hunting in spring, when birds migrate over the country to their European breeding grounds. Malta’s derogation of the European Commission’s ban can only be legally permissible if no alternative solutions to spring hunting exist. Using figures provided by hunters, we show that greater numbers of European Turtle-dove Streptopelia turtur and Common Quail Coturnix coturnix – the two species for which spring hunting is allowed – are hunted in autumn than in spring. We show that statistics on the number of birds hunted in spring, which hunters are legally obliged to provide to authorities, are under-reported: they are not correlated, at times negatively correlated, with data on the daily influxes of birds, and they spike in the final week of the season, consistent with the hypothesis that hunters under-report to avoid reaching quotas which would result in an early season closure. Finally, while there are wide error margins around the numbers, independent annual estimates of turtle-doves hunted in Malta imply spring hunting is a conservation concern beyond the country itself. Each spring, hunters in Malta kill the equivalent of between 2.4% and 4.4% of Europe’s turtle-dove population and 0.4% and 0.5% of its quail population.

Abstract:

One of the main problems in comparative studying animal behavior is searching for an adequate mathematical method for evaluating the similarities and differences between behavioral patterns. This study aims to propose a new tool to evaluate ethological differences between species. We developed the new compression-based method for the homogeneity testing and classification to investigate hunting behavior of small mammals. A distinction of this approach is that it belongs to the framework of mathematical statistics and allows one to compare the structural characteristics of any texts in pairwise comparisons. To validate a new method, we compared the hunting behaviors of different species of small mammals as ethological “texts.” To do this, we coded behavioral elements with different letters. We then tested the hypothesis whether the behavioral sequences of different species as “texts” are generated either by a single source or by different ones. Based on association coefficients obtained from pairwise comparisons, we built a new classification of types of hunting behaviors, which brought a unique insight into how particular elements of hunting behavior in rodents changed and evolved. We suggest the compression-based method for homogeneity testing as a relevant tool for behavioral and evolutionary analysis.

Abstract:

As few studies have analysed local variability in populations of wild boar Sus scrofa in Western Europe in recent years, our understanding of ecological processes currently affecting this species is limited. To analyse questions regarding local variability in wild boar abundance, we used information from 442 traditional drive hunts monitored throughout eight hunting periods in the Pyrenees mountain range (Urdués, N Spain). Results showed temporal oscillations in abundance, and a non–linear decrease of 23% in the number of wild boar seen per drive hunt between 2004 and 2011. Numbers of dogs and hunters per drive hunt also affected indexes of wild boar abundance. Inter–annual variations in bag size may cause overestimations of variations in boar abundance and may even deviate from the population dynamics inferred from the number of wild boars seen per drive hunt. The multimodal patterns of wild boar abundance during the hunting periods suggest migrations in the Pyrenees. Our findings highlight the limitations of hunting bag statistics in wild boar. Further studies are required to guarantee information–based sustainable management of wild boar populations.

Abstract:

Ungulate populations and browsing intensities following the reintroduction of lynx in the canton of St. Gallen In the context of the project “Lynx resettlement north-east Switzerland” (LUNO), the Eurasian lynx (Lynx lynx L.) was reintroduced in the canton of St. Gallen from 2001. As a consequence of reduced roe deer (Capreolus capreolus L.) and Alpine chamois (Rupicapra rupicapra L.) population sizes, one goal was the reduction of browsing intensities in young forest stands. This study investigates interactions between the levels of this trophic cascade by means of data on lynx distribution, roe deer and chamois populations (hunting statistics and population estimations) as well as browsing intensities. The results have shown significantly reduced roe deer and chamois population sizes in the years after lynx reintroduction. The effect of lynx could have worked cumulatively with factors like hunting, weather conditions and diseases (chamois). Within the chamois population, the lynx probably affected primarily the forest chamois, although before and after the lynx presence other causal reasons have been responsible for population decreases. Furthermore, there was noted a significantly positive relationship between hunting statistics (as an indicator of local ungulate population sizes) and browsing intensities, although the size of local ungulate populations was one influencing factor among many more. The browsing intensity of silver fir (Abies alba Mill.) was significantly reduced after lynx reintroduction in the core area of lynx distribution. All results have shown significant correlations and suggest an indirect influence of lynx on browsing intensities of silver fir. However, causal connections should be analysed in further studies.

Abstract:

The condition of the populations are useful parameters for the reasonable game management. In this study the physical condition of Brown hare stocks (Lepus europaeus, Pallas 1785) was analyzed, measured body weight (BW) and determined kidney fat index (KFI). These methods were applied during our survey in the hunting period of 2014/15 and 2015/16. In total 272 (123 male and 149 female) samples were collected from two hunting areas in Great Plain (from County Békés and Jász-Nagykun Szolnok). The aim of our work was to collect data concerning the conditions of the populations. All hares was sexed and classified in 2 age groups (young <1years), and (old> 1years). The age was established by Stroh-mark in the hunting field and by dried eye lenses in the laboratory. BW and the weight of the kidney and perirenal fat was measured and the data were statistically analysed (group statistics, Levene’s test for Equality of Variances and, t-tests for Equality of Means). As a result of our examination the range of KFI was 1.25-5.14. The weight of perirenal fat was between 2-34gramm.KFI was greater in females than males. The average BW of the hares in every age groups were less than it is according to literature dates, however the conditions of the hares were good and in very good in both hunting areas. The BW and the amount of the perirenal fat in adult female hares were the greatest.

Abstract:

The transient-state stability analysis for the trajectories of Tyson's equations for the cell-division cycle is given by the so-called KCC-Theory. This is the differential geometric theory of the variational equations for deviation of whole trajectories to nearby ones. The relationship between Lyapunov stability of steady-states and limit cycles is throughly examined. We show that the region of stability (where, in engineering parlance, the system is “hunting”) encloses the Tyson limit cycle, while outside this region the trajectories exhibit a periodic behaviour.

Abstract:

Poor soils and high rainfall mean that the high productivity of the forests, an assumption that drives the development of the forest zone, is an illusion. The potential of the forests to produce meat, from wild or domestic herbivores, is limited. Growing human populations and shrinking forests accelerate pressures on forest resources faster than national statistics indicate. A simulation model demonstrates the effects of growing hunting pressure on one monkey and two duiker species. A version of this model that includes random variation shows that large harvests can be obtained for many years, but that a population collapse can happen suddenly; there is no period of gradually declining harvests. The accelerating hunting pressure in a zone of low productivity, shrinking habitat for monkeys and antelopes, the dynamics of non-linear systems, and natural environmental variation that affects reproduction and survival will lead to a collapse of hunted populations across the forest zone. We are now seeing the bushmeat boom and soon we will see the bushmeat bust.

Abstract:

In the conditions of industrial milk production and productivity growth in cows, the increase in the duration of the inter- calving period is noted. This is due to a somewhat prolonged process of involution of the uterus after calving in high-yielding animals and prolongation of the service-period due to lack of detection of animals in estrous cycle. Depending on the technology of maintenance and qualification of service personnel, the number of such animals may increase. The contributing factors include the year-round stall system of keeping cows, the uncontrolled retention of animals in large groups, short intervals of detection of animals in hunting and others. The paper uses the materials of the first-time animal and veterinary record of a number of husbandries specializing in industrial milk production with different systems of keeping animals and the detection of animals in hunting. Methods of hormonal stimulation of sexual intercourse in cows were studied in the state enterprise "Khrystynivske" (n = 243) for the binding system for the maintenance of cows and auto-mated control of motor activity of cows for unbroken maintenance for the detection of animals in hunting – LLC "Nd. a. Lesia Ukrainka" (n = 74). For hormonal stimulation, methods using estrogens and prostaglandins were used: the protocol Ovsinh (n = 164) and the use of progesterone (preparation Delta® Ceva Santa Animale) (n = 79). The obtained results were sorted by the methods of variation statistics in the software product Statistica 12.5. An analysis of the detection of spontaneous hunting in animals by the traditional method - observing them during the walk allowed us to establish that in the first cows, the indicators of regenerative (VP) and service-periods (SP), under the same conditions of abstinence and feeding, differed from full-age cows in the duration of only one sexual cycle (20–21 days), for almost identical index of insemination (IO). Analysis of the results of determining the sexual cycles of cows using the help of DATA SLOW software and Triolact sensors conducted at the LLC nd. a. Lesia Ukrainka of Kovel region of Volyn oblast (n = 74) showed that even short-term hunting, which takes place within 2–3 hours, can detect and carry out insemination of animals. The obtained results coincide with the duration of the service-period during the systematic visual detection of animals in the stage of sexual hunting, but there is a reduction of the three-fold of the recovery period, the duration of which is associated with certain difficulties of visual detection in animals of the first hunting (irreducible manifestation , short duration and others). Also, the results of the analysis confirm the increase in the service-period in cows-primates for approximately the duration of one sexual cycle. In the following cases, there is a decrease in the variability of reproduction rates. The growth of milk productivity negatively correlated with the indicator of the duration of service-period in cows. The force of influence was almost 96% (P < 0.01). In cases of tied animals maintenance in the first place, methods of hormonal stimulation of sexual hunting in cows are obtained. Indicator of efficiency of detection of animals in hunting during the period of maintenance was 28–35%, and during the summer-camp – grew to 47–62%. Analysis of the duration of the service period and the index of insemination with the synchronization of cows according to the protocol "Ovsinh" has shown a decrease in the effectiveness of insemination of cows for stimulated hunting. Fertility of animals after the first insemination was 20.1%, and after the second procedure the introduction of hormonal drugs increased by 8–12% and was 38%. In the application of progesterone in the form of vaginal applicators "Pride Delta" results were better – the fertility rate from the first insemination was 37%, and from two – 56%. As with the use of prostaglandin, and in the application of the protocol "Ovsinh" there is a tendency to increase the effectiveness of insemination, depending on the duration of the recovery period, that is, the time from calving to the use of the drug.

Abstract:

Information and statistics including trade statistics on catches of white whales or belugas (Delphinapterus leucas) in West Greenland since 1862 are presented. The period before 1952 was dominated by large catches south of 66o N that peaked with 1,380 reported kills in 1922. Catch levels in the past five decades are evaluated on the basis of official catch statistics, trade in mattak (whale skin), sampling of jaws and reports from local residents and other observers. Options are given for corrections of catch statistics based upon auxiliary statistics on trade of mattak, catches in previous decades for areas without reporting and on likely levels of loss rates in different hunting operations. The fractions of the reported catches that are caused by ice entrapments of whales are estimated. During 1954-1999 total reported catches ranged from 216 to 1,874 and they peaked around 1970. Correcting for underreporting and killed-but-lost whales increases the catch reports by 42% on average for 1954-1998. If the whales killed in ice entrapments are removed then the corrected catch estimate is on average 28% larger than the reported catches.

Abstract:

Environmental management is a priority for the development of science, technology and technology, which cannot be carried out without monitoring the state of the environment. Industrial-oriented natural ecosystems are experiencing significant anthropogenic pressures, resulting in an increased negative impact on the environment and a reduction in biodiversity. In this work, on the territory of the Kemerovo region - Kuzbass (on the territory of 19 administrative districts), an analysis of the impact of the area's planting on the number of hunting animals was carried out. This analysis was performed by correlation method. The source of information was official data for the period from 2015 to 2019 of the Ministry of Natural Resources and Ecology of Kuzbass, the Department for the Protection of Animal Objects of Kuzbass, the Department of Forestry of Kuzbass, the Federal State Statistics Service of Kuzbass. The results of the landfill study showed a decrease in dynamics, which is associated with intensification of agriculture, unfavorable climatic conditions and forest fires. The largest decrease in the level was observed in the Izhmorsky, Kemerovo, Mariinsky and Prokopyevsky districts. The results of the study of the dynamics of the number of hunting animals (ungulates, bears and fur animals) presented in this work showed a stable, annual growth in numbers. The predominant ungulates of the region are Siberian roe deer and European elk of 5 species, fur animals are white hare, squirrel, common beaver, ondatra, sable, common badger, European mink of 17 species of animals, bears in the region are represented by a brown bear. There was a high and moderate inverse dependence of the dynamics of the number of brown bear, ungulates on the influence of the salinity of the fixed hunting grounds of various territories. The results showed that the increase in the number of bears and ungulates negatively affects the greenland of certain territories, which does not contradict the literary data.

Abstract:

Harbour seals (Phoca vitulina) have been harvested in Iceland since the first settlers arrived in the 9th century. Pups were generally netted, clubbed and harpooned until 1875 when general use of guns for hunting began. Seal-hunting has been traditional amongst the farms legal rights. Seal hunting was an important supplement to other economic resources. Harbour seal skins, salted ordried, were exported and large dataset of catch statistics is available from trading logbooks since the late 19th century. In the early 20th century catch was about 6,000. In the ‘bounty’ period 1982 – 1989, maximum catches were of 4,000 animals with about 350 hunters participated; in 2006 catches were only about 100 animals with 18 hunters. After 1989 the population continued to decline even though catches decreased markedly. Unreported by-catch in fishing gear, hunt for local consumption and shooting of seals swimming in salmon rivers estuaries may have kept the total removal from the stock above sustainable levels. A considerable Icelandic knowledge base had been compiled about the biology of the harbour seal since the late 16th century, with the first written reference in 1588-1589. In the last decades, research on various aspects of its biology and monitoring have been intensified, with focus on abundance, distribution, diet and nematode infestation. The main results show that the Icelandic harbour seal population - has declined annually about 5% in the period 1980-2006, - was most abundant on the NW-coast, - feeds mainly on sand-eels and gadoids, - and was less infected with anisakid nematodes than grey seals. Seal watching, as a low-consumptive indirect utilization, may represent a new economical opportunity if properly regulated.
