The interaction of Sika deer (Cervus nippon Temminck 1838) with lowland heath mosaics.
No full textSika deer (Cervus nippon) has become an invasive species in many parts of the world. In the south of England large populations appear to be concentrated in landscapes comprising of mosaics of lowland heath, woodlands and grassland. Despite the association between the distribution of Sika deer and that of lowland heath, little is known regarding the extent to which Sika deer utilize lowland heath and their impacts on its plant and animal communities. The aim of this thesis was to investigate the ecological interaction of Sika deer with lowland heath set in a mosaic of other habitats. Specifically, the main three
objectives of this thesis were: i) to investigate the different ecological factors affecting the distribution and habitat use by Sika deer; iii) to explore consistency in Sika deer habitat associations as a potential tool to predict the distribution and abundance ofSika deer; iii) to
investigate the ecological impacts of the usage of areas of lowland heath by Sika deer upon plant and animal communities oflowland heath. Results showed that Sika deer distribution and habitat use are affected by the availability of habitats, landscape structure and human
disturbance at both the landscape and home range scale (i.e. few hundred of hectares and few dozens of hectares respectively). At the landscape scale, Sika deer seemed to use the requirement for safe access to pastures as the main criteria for their habitat selection. At the home range scale, the criteria of choice in the use of resources by Sika deer seemed to be related to a requirement for an appropriate balance of food and cover as the selection of
pastures and cover were inversely related to their availability. However, human disturbance, as a form of perceived risk, was also a limiting factor of habitat use at the home range scale. Consistencies in the habitat selection by Sika deer at the landscape scale between areas with similar landscape were detected, which could potentially be used to develop models to predict the distribution and abundance of Sika deer and their subsequent
impacts in areas of lowland heath. This study has found a different response of plant and animal communities between dry and wet heath to levels in usage of areas of heath by Sika deer. The existence of a threshold in the local density of Sika deer on areas of heath above which dry lowland heath showed signs of decline in quality has also been identified

The research identifies which of these alternatives will work as a proposal for improvement in the area of human resources in order to strengthen the processes of recruitment and retention of personnel, focusing on the use of technological tools and the use of mass media such as social networks, all in accordance with the requirements that Sika needs in order to develop its potential in this area.Administrador (a) de EmpresasPregrad
Occupancy of breeding sika deer populations and competition with white-tailed deer on the Delmarva Peninsula, USA
No full textBowman, Jacob L.Sika deer were introduced to the Delmarva Peninsula in 1916 and have become an important game species, cultural icon, and agricultural pest. Although sika deer bring many economic benefits to the Eastern Shore, their ongoing range expansion, potential distribution, and impacts on native species are poorly understood. My objectives were to 1) identify landscape characteristics that predict occupancy of breeding sika deer populations in order to assess potential range across the Delmarva Peninsula and 2) assess whether competition with sika deer impacts white-tailed deer. I used trail cameras baited with 11kg of corn to survey 100 sites in Dorchester, Wicomico, and Somerset counties in Maryland during the winters of 2022, 2023, and 2024. Sika deer occupancy probability increased with increasing forest or marsh cover at the 161 ha scale (95% CI 0.015, 0.056). An index of sika deer abundance was negatively associated with an index of abundance for white-tailed deer (95% CI: -0.099, -0.039), white-tailed deer detection probability (95% CI: -0.096, -0.131), and occupancy probability (95% CI: -0.57, -0.13). Sika deer will likely colonize southern portion of the Delmarva Peninsula, characterized by extensive forest and marsh cover and high connectivity. Highly suitable patches set within the agriculturally dominated northern half of the peninsula may lack the connectivity required for sika colonization. Sika deer likely cause declines in sympatric white-tailed deer populations but agriculturally dominated landscapes may act as refugia for white-tailed deer and population management may facilitate the coexistence of both species.University of Delaware, Department of Entomology and Wildlife EcologyM.S
Design of a communication strategy for new technologies for cooperation and work between areas in Sika Colombia
No full textLa adecuada tecnología y la buena colaboración entre áreas, son factores indispensables en el buen funcionamiento de una compañía, sin embargo, no todas las compañías corren la suerte de contar con ambas, como lo es en el caso de la empresa Sika Colombia. Por esta razón, este proyecto tiene como intención crear una estrategia de comunicación, que permita mejorar la comunicación entre las áreas, a través de la implementación de nuevas tecnologías de comunicación, con el fin de mejorar la cultura organizacional, los procesos internos, la eficacia, entre otras.Adequate technology and good collaboration between areas are essential factors in the proper functioning of a company, however, not all companies are lucky enough to have both, as it is in the case of the company Sika Colombia. For this reason, this project intends to create a communication strategy that allows improving communication between areas, through the implementation of new communication technologies, in order to improve organizational culture, internal processes, effectiveness , among other.Administrador (a) de EmpresasPregrad

Markkinamarginaalit sika- ja siipikarjatalouteen
No full textSika- ja siipikarjatalous on alttiina äkillisille kysynnän ja hinnan muutoksille. Lisäksi sika- ja siipikarjatilat ovat viime vuosina olleet tukijärjestelmän muutosten kohteena. Tilojen kannattavuus on heikentynyt ja tuotantomäärät ovat laskeneet. Vuosina 1995–2014 sekä sian- että siipikarjanlihan kuukausihinnan keskihajonta on ollut suuruudeltaan yli 10 prosenttia hinnan keskiarvosta. Tuotannon talouden kannalta vielä äkillisempiä shokkeja aiheutuu rehun hinnan vaihtelusta.
Sika- ja siipikarjatalouden kansallinen tuki irrotettiin tuotannosta koko maassa vuodesta 2009 alkaen. Etelä-Suomen kansallisen tuen kaudella 2008–2013 ja varsinkin sen kahtena viimeisenä vuonna sika- ja siipikarjatalouden tuen kokonaismäärä aleni voimakkaasti. Vuosina 2014-2020 tuki jatkuu edelleen alenevana tuotannosta irrotettuna tukena, joka perustuu Suomen EU-liittymissopimuksen (artikla 141) sijasta EU:n maatalouden markkinajärjestelyasetukseen.
EU:n yhteisen maatalouspolitiikan (YMP) II-pilarina oleva maaseudun kehittämisohjelma uudistui vuonna 2014. EU-tasolla YMP:n II-pilari sisältää mahdollisuuden maatilojen riskinhallintavälineiden kehittämiseen. Näistä yhtenä mallina on tulojenvakauttamisväline. Tulojenvakauttamisvälinettä ei kuitenkaan ole sisällytetty Manner Suomen maaseudun kehittämisohjelmaan vuosille 2014–2020. Tässä julkaisussa esitetään eksogeeninen kannattavuusmittaristo, markkinamarginaalit, jotka mahdollistavat riskienhallintavälineiden ja niihin liittyvien uusien tukijärjestelmien kehittämisen uudelle ohjelmakaudella eli vuodesta 2020 alkaen. Markkinamarginaalit julkaistaan automaattisesti päivittyvinä indekseinä Luonnonvarakeskuksen sivuilla osoitteessa www.luke.fi/markkinamarginaalit.
Markkinamarginaaleja hyödynnetään vakioituihin katteisiin perustuvissa indeksivakuutuksissa, joilla suojaudutaan hintariskejä vastaan. Indeksivakuutuksia voidaan tukea maaseudun kehittämisohjelman puitteissa. Markkinamarginaaleilla saadaan esiin indeksivakuutusten edut. Indeksivakuutukset eivät kärsi vakuuttajan ja vakuutettavan välisestä epäsymmetrisestä informaatiosta. Niihin ei siten liity moraalikadosta tai käänteisestä valikoitumisesta johtuvia ongelmia. Vakioituihin katteisiin perustuvia marginaalivakuutuksia on laajasti käytössä Yhdysvalloissa. Marginaalivakuutukset ovat juuri rantautumassa Eurooppaan ja nyt julkaistavien markkinamarginaalien avulla niitä voidaan kehittää myös suomalaisten sika- ja siipikarjatilojen riskienhallintatarpeisiin.201
