Published: May 2018

Counts of reproductive units, i.e. family groups, constitute the main monitoring index for lynx Lynx lynx populations in Scandinavia. However, for some purposes it is necessary to extrapolate from the number of family groups to obtain an estimate of total population size. Using data on survival and reproduction from radio‐marked lynx from three Scandinavian study areas, we simulated the lynx population structure in February. The average proportions of family groups out of all independent individuals, i.e. adults and yearlings, in these simulations were 21% ± 2.1 (SD), 22% ± 3.6 and 27% ±3.1 for the data sets from northern Sweden (Sarek), southeastern Norway (Hedmark) and south‐central Sweden (Bergslagen), respectively, and the overall mean for all three study areas was 23% ± 3.8. This translated into extrapolation factors of 6.14 ± 0.44,6.24 ± 0.73 and 5.48 ± 0.40 for the three study areas, respectively, leading to an overall mean for all three study areas of 5.95 ± 0.64. We conclude, that it is possible to extrapolate from the number of family groups to obtain an estimate of total lynx population size with a statistical measure of uncertainty.
Nest site characteristics and nest success in red grouse Lagopus lagopus scoticus
Authors: Campbell Steven , Smith Adam , Redpath Stephen , Thirgood Simon
Published: May 2018

We assessed the influence of habitat characteristics on nest site selection and nest success of red grouse Lagopus lagopus scoticus in three populations on managed moorland in Scotland during 1998–1999. We measured habitat characteristics at the nests of 148 radio‐tagged female grouse and compared them with similar measurements taken at fixed and random points within their home range. Red grouse nested in vegetation that was significantly taller and denser, and with greater canopy cover, than points adjacent to nests or to random points. They nested more in mature heather and less in grass‐dominated vegetation than would be expected by chance. Red grouse nest success was high with 77% initial success rising to a minimum of 80% success once re‐nesting had occurred. Nest success was weakly related to vegetation height in 1998, but no similar relationship was found in 1999. We suggest that the high nest success of red grouse and the relatively small influence of habitat characteristics on the outcome of nesting attempts is due to predator control on managed grouse moors in Scotland.
Food requirements of grey partridgePerdix perdixchicks
Authors: E. Southwood T. Richard , Cross David J.
Published: May 2018

Experimental investigations showed that during the first 10 days of their life partridgePerdix perdixchicks grew most vigorously on a high protein value diet composed largely of insects. They grew less quickly on rearing crumbs and were unable to survive when fed entirely on seeds. We determined the daily uptake of food and, from carcass analysis, the proportion assimilated. From this information the average daily food requirement in terms of the dry weight of insects was calculated as 0.80 g on day 2 and 1.95 g on day 9. We calculated the number of individual insects of various groups required daily, if feeding was restricted to one group, and the amount of habitat that would need to be searched if insects were taken randomly. Resistance to chilling was shown to be correlated with weight and not with age. Thus shortage of insect food in the first few days of life would extend the period when the chicks are particularly vulnerable to lower temperatures and rain, effects that have also been demonstrated in other studies.

Published: May 2018

In this article we describe 77 arctic fox Alopex lagopus dens in Vindelfjällen, northern Sweden, with regard to distribution, morphology and fox use. The density of dens in the area was 1/21 km2 and dens were more spaced than random. The dens were situated at a mean altitude (± SD) of 915 m a.s.l. ± 74, were on average 3.5 km ± 1.88 from the nearest tree line, had a mean number of 44 den openings ± 32 and a mean area of 277 m2 ± 237. During the 21‐year study period, 31 dens were used by arctic foxes and 10 by red foxes Vulpes vulpes. Number of den openings, den area, altitude and distance to the nearest tree line explained 36% of arctic fox den use (P < 0.001) and 21 % of red fox use of arctic fox dens during the study period (P = 0.01). Arctic foxes used dens at higher altitude (P = 0.03) and further away from forest than did red foxes (P = 0.03), and tended to breed in dens with more openings (P = 0.08). Arctic foxes used some breeding dens more frequently than others (P = 0.002). Among the breeding dens, both den use and litter size were positively related to den area (den use: P = 0.04; litter size: P < 0.001). Successful arctic fox breeding dens in Sweden thus appear to be characterised by large size and many openings, and they are situated far away from forest at relatively high altitudes.
‘Mass’ deaths of moose Alces alces in southern Sweden: population level characterisation
Authors: Broman Emil , Wallin Kjell , Steén Margareta , Cederlund Göran
Published: May 2018

Moose Alces alces suffering from Moose Wasting Syndrome (MWS) have been observed in Sweden since 1985. In this study a population characterisation of MWS is done based on moose delivered to the National Veterinary Institute of Sweden during 1985–1989, public reports of non‐traumatic moose deaths during 1991–1998, and radio‐collared moose in one high‐ and one low‐report frequency area. Moose suffering from MWS have been observed nationwide, but deaths from non‐traumatic causes, including MWS, are most frequently reported from the county of Älvsborg. Nationwide reports of non‐traumatic deaths peaked in 1992, but no peak was observed in Älvsborg. We suspect that the temporal as well as the spatial patterns observed were largely due to information about the MWS by the media, research activities and local concern. The age‐specific mortality pattern of non‐traumatic deaths did not differ, in either sex, between one high‐ and one low‐report frequency area. The risk of dying from non‐traumatic causes increased with moose age. Reports of female moose either suffering from MWS or having died from other non‐traumatic causes largely outnumbered reports of males (1,349 and 387, respectively). Our results of age‐specific risks suggest, however, that females are less vulnerable to non‐traumatic mortality than males. The discrepancy between report frequencies and death risks is explained by the fact that the population sex ratio is female‐biased (by sport harvest), and few males reach the age at which the risk of dying from non‐traumatic causes increases. In the area from which most of the reports came the non‐age‐specific yearly risk of dying from non‐traumatic causes, including MWS, was estimated to be 3.5% for females and 3.0% for males. Because there are other non‐traumatic causes of death, the risk of dying from MWS exclusively is lower than our risk estimates indicate. There is no immediate risk of local extinction of moose due to MWS, as we estimate that the population would increase if culling was stopped.
Mengidentifikasi Segmen Pasar Dan Memilih Pasar Sasaran

Target market identification is a necessary step in planning and developing marketing strategies. In situations in which the consumer faces many choices, the success of product marketing will be largely determined by the suitability of the product to the needs of consumers in a particular segment. The company could not connect with all its customers in a large, wide, or diverse market. But they could divide market into a consumer group or segment with different needs and wants. On this stand, the company must identify which market segments it could serve effectively. Modern marketing strategies have currently used STP (Segmenting, Targeting, Positioning): (1) Segmenting is grouping markets into homogeneous consumer groups, in which each group can be chosen as targeted market for marketing a product. (2) Targeting. After the company identifies the market segment opportunity, then it will evaluate the various segments to decide which segment is considered the target market. (3) Positioning is an image formed in the mind of a consumer concerning the names of company or product.

Hak Pilih (Khiyar) Dalam Transaksi Jual Beli Di Media Sosial Menurut Perspektif Hukum Islam
Authors: ZA Moh. Ah. Subhan
Published: May 2018

Islam has taken into account the right to select (khiyar) in buying and selling transaction with the aim of avoiding possible fraud, forgery and so on so as to create a willingness between each party. Khiyar could be conducted when sellers and buyers meet directly physically as that in any buying and selling transaction. While in the modern buying and selling process done in cyberspace, especially in social media such transaction raises the question "what is the khiyar in the cyberspace transaction?" Although the transaction occurs two-side interaction, between the seller and the buyer both do not meet directly in one place and goods traded could not be held or reversed. Buyers could only see photos or video of goods to be purchased along with its prices. Based on the writer's study, it could be concluded that the buying and selling transaction in social media which although between the seller and the buyer both do not meet directly physically—only in the virtual world—the transaction is still considered in one majlis so the khiyar is still considered adequate and valid. Because the so-called one majlis should not be interpreted that both the seller and buyer are equally present in one place. But what is meant by one majlis is, the so-called ijab qabul is done within the time in a contract, in the sense that after the ijab is pronounced followed with the so-called qabul in a transaction or when pronouncing ijab qabul is not interspersed with other words which according to custom is assumed to be capable of interrupting it

Published: May 2018

In the present investigation, two different clay samples from the region of Menemen (İzmir) and the region of Kınık (Bilecik) were characterized by mineralogical, chemical and thermal analyses and different technological tests. The drying sensitivity of the clay bodies was also studied bydetermining Drying Sensitivity Index. The results revealed that the Menemen Clay (MC) composed of kaolinite and muscovite clay minerals whereas Kınık Clay (KC) consists mostly of clinochlore and muscovite. The MC contains about 50% clay minerals and 35.71% quartz whereas the KC has about 41% clay minerals and 50% quartz. As a result of this composition, the firing shrinkage and total shrinkage values of the MC were higher than that of the KC. On the other hand, the KC presents a higher value of plasticity index (PI) than the MC. On the evaluation of drying sensitivity of two ceramic muds, it was concluded that the KC has the less Drying Sensitivity Index (DSI) (0.75) value than the MC (0.84).

Published: May 2018

Mekanik aktivasyon, temel bir metalurjik süreç öncesinde mineralin bu süreçlerdeki durum
değişimleri sırasındaki reaktifliğini artırmak üzere uygulanan bir ön-işlemdir. Cevher hazırlama
proseslerinde mekanik aktivasyon işlemleri öğütme değirmenlerinde gerçekleştirilir. Çünkü cevher
hazırlama proseslerinde mekanik aktivasyonun en önemli etkisi, fizikokimyasal özelliklerinde
değişikliğe yol açacak şekilde mineral tanelerinin ufalanmasıdır. Mekanik aktivasyon sırasında
mineralin kristal yapısı bozulur ve daha reaktif türler oluşur. Böylece, aşırı şartlar altında öğütülmüş
mineral, elden geçirileceği metalurjik süreç sırasında artık daha aktif olarak davranacak ve bu
durum, sürecin hızını artıracaktır. Tepkime sıcaklığını düşürmek, çözünürlük miktarı ve hızında
artış sağlamak, suda çözünür bileşiklerin hazırlanması, basit ve daha ucuz reaktör üretimi ve daha
kısa tepkime süresi gereksinimi mekanik aktivasyonun bazı üstünlüklerindendir. Bu nedenlerle,
mekanik aktivasyon metalurjik süreçlerde çekici bir konu olmaktadır. Bu çalışmada ise, çeşitli
cevher hazırlama tesislerinde, hidrometalurjik elden geçirim süreçlerinde mekanik aktivasyonun
uygulamalarını inceleyen birçok çalışma ele alınarak incelenmiştir.

Generalization in fifth graders within a functional approach
Authors: Pinto Eder , Cañadas María C.
Published: May 2018

This article discusses evidence of 24 fifth graders’ (10-11 year olds’) ability to generalize when solving a problem which involves a linear function. Analyzed in the context of the functional approach of early algebra, the findings show that 3 students generalized both when solving specific instances and when asked to provide the general formula; while 15 students generalized only when asked to define the general formula. The results are described in terms of the functional relationship identified, the types of representation used to express them and the type of questions in which students generalized their answers. Most of the pupils who generalized did so based on the correspondence between pairs of values in the function at issue.Generalización de estudiantes de quinto de primaria desde un enfoque funcionalEn este artículo presentamos evidencias de generalización de 24 estudiantes de quinto de primaria (10-11 años) al resolver un problema que involucra una función lineal. Desde el enfoque funcional del early algebra, los hallazgos muestran que 3 estudiantes generalizaron al trabajar con casos particulares y cuando se les pide expresar la regla general; mientras que 16 estudiantes solo lo hicieron cuando les pedimos expresar la regla general. Describimos los resultados en términos de la relación funcional identificada, los tipos de representaciones que emplearon para expresar dichas relaciones y el tipo de pregunta en la cual los estudiantes generalizaron. La mayoría de los estudiantes que generalizaron establecieron una relación de correspondencia entre los pares de valores de la función.Handle: http://hdl.handle.net/10481/50159Doi: https://doi.org/10.30827/pna.v12i3.6643Scopus record and citations

Genetik menjadi kunci konservasi karena berperan penting dalam  mempertahankan dan memulihkan populasi dari kerusakan. Kerusakan pada ekosistem terumbu karang dapat menjadi pemicu kepunahan organisme laut. Salah satu organisme yang tidak terhindar dari kerusakan tersebut ialah Sarcophyton trocheliophorum. Kerusakan tersebut dapat menyebabkan menurunnya keragaman genetik S. trocheliophorum. Tujuan dari penelitian ini adalah menganalisis keanekaragaman genetik dari S. trocheliophorum yang terdapat pada tiga populasi di Perairan Jawa, Sulawesi dan Nusa Tenggara serta mendeskripsikan implikasinya terhadap kawasan konservasi  di Indonesia. Penelitian ini menggunakan penanda genetik ND2 untuk menganalisis struktur populasi, konektivitas, dan keragaman genetik. Keragaman genetik S. trocheliophorum pada Perairan Jawa, Sulawesi, Nusa Tenggara masing-masing 0.600, 0.815, dan 0.972. Keragaman genetik pada populasi Perairan Jawa lebih kecil dibandingkan pada Populasi Perairan Sulawesi dan Nusa Tenggara. Hal ini dimungkinkan karena banyaknya aktivitas manusia pada pesisir utara Laut Jawa, sehingga berdampak pada menurunnya ukuran populasi S. trocheliophorum. Oleh karena itu perlu adanya perlindungan yang ketat pada populasi Jawa untuk menjaga kelestarian keanekaragaman hayati Indonesia.
