Metsonsoitimen riistapainoitteinen metsÀnhoito : Case: A. Ahlström Kiinteistöt Oy, PöytyÀ
MetsÀnhoito kÀsitteenÀ on lÀhes jokaiselle metsÀnomistajille tuttu termi, mutta riistataloudellinen metsÀnhoito on osalle tuntematon. Metson soidinalueet saavat jo normaalissa metsÀnhoidossa erityiskohtelun, koska nÀmÀ ovat merkittÀviÀ alueita riistan kannalta. Omassa työssÀni perehdyn enemmÀn riistametsÀnhoitoon metson soidinalueella.
OpinnÀytetyöni tavoite on turvata metson soitimen sÀilyminen hakkuusuunnitelmalla. Soidinalueen turvaaminen tapahtuu hakkuuajankohtien pitkittÀmisellÀ ja sÀÀstÀmÀllÀ metsolle suojapaikkoja lÀhellÀ soidinaluetta. Alueen metsien riistan-hoidollinen suunnittelu ei vain anna suojaa metsolle, vaan toimenpiteistÀ hyötyvÀt myös useammat riistalajit.
EtukÀteen minulla oli tiedossa, ettÀ alue on yksi EtelÀ-Suomen merkittÀvimpiÀ metson soidinalueita. NÀiden paikkojen sÀÀstÀmisellÀ ja riistanhoidollisella suunnittelulla on erittÀin suuri merkitys metsokannan sÀilymiselle elinvoimaisena. Metso on suurten metsien lintuna kÀrsinyt metsÀtaloudesta. JÀljellÀ olevista suurista soidinpaikoista on syytÀ huolehtia.Forestry as a term is usually known by forest owners, but wild game favouring is not known that much. Capercaillie is a largest grouse in Finland. Capercaillie courting areas already have a special treatment in forestry, because they have a huge effect on capercaillie populations. This thesis became familiar more with game favouring forestry in capercaillie courting areas.
The purpose of the thesis was to secure capercaillie courting area using a logging plan. Capercaillie courting area securing happens by changing the timing of the logging and by saving protected areas near the courting area. Game favouring forestry does not just give shelter to capercaillie, but also other wild game benefits.
It is known that this area is one of the most significant capercaillie courting areas in Southern Finland. Protecting these places and having game favouring plans have a huge effect on capercaillie survivability. Capercaillie, a bird living in large forests, has suffered from modern forestry. There are few known large capercaillie courting areas left, and they must have taken care of
Photon burst mass spectrometry--ultrasensitive detection of rare isotopes
Progress is reported on the development of a new technique for measurement of trace levels of radioisotopes which is based on fluorescence detection of output from a mass spectrometer. Significant achievements include the observation of fluorescence and burst signals from Kr isotopes, including enriched samples of {sup 85}Kr with a 4-collector system. An abundance sensitivity is demonstrated with {sup 83}Kr and {sup 85}Kr
Correction: Overexpression of Mineralocorticoid Receptors Partially Prevents Chronic Stress-Induced Reductions in Hippocampal Memory and Structural Plasticity
Sholl plots in stressed and non-stressed control and MR-tg mice.
<p>(A) The average dendritic length measured at specific distance points from the soma in all experimental groups. Analysis was based on the same cell groups as used in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0142012#pone.0142012.s002" target="_blank">S2 Fig</a>. Data are expressed as mean ± SEM. (B) Representative image of a CA3 pyramidal neuron analyzed at various bins representing the distance from the soma. We restricted the analysis to the apical dendrites only. Calibration bar: 20 Όm.</p
Neuroendocrinological parameters to determine the effectiveness of the CUS paradigm.
<p>These parameters included: (A) body weight gain (g), (B) thymus weight (mg / g body weight), (C) adrenals weight (mg / g body weight and (D) corticosterone levels. Data are expressed as mean ± SEM with p-values based on post-hoc LSD. nâ„20 mice per group for A,B and C and n = 6â8 for D. *: significant, p †0.0125.</p
Object in context.
<p>Left: schematic representation to indicate the setup of the object-in-context experiment. A) Mice were initially habituated in a context that had no object. B1) During training, mice were placed in the same context but with two identical objects and then placed in a novel context with two identical novel objects (B2). (C) Finally the mice were placed in the latter context but with one object being replaced by an object from the first context. (D) The discrimination index as observed from the object in context experiment. Data are expressed as mean ± SEM with p-values based on post-hoc LSD. n = 9 mice per group. *: significant, p †0.0125.</p
Neurogenesis results in stressed and non-stressed control and MR-Tg mice.
<p>Right panel shows representative examples of BrdU, Ki67 and DCX labeled cells being scored (D-F, arrows, calibration bar: 50 Όm). Left panel shows the bar graphs on the left summarize the averaged results for: (A) BrdU positive cells, (B) Ki67 positive cells and (C) DCX positive cells. For each marker we analyzed the total number of cells, the number of cells along the rostral and caudal subareas of the hippocampus as well as the numbers for two subregions that make up this total number (total infra and total supra). Data are expressed as mean ± SEM with p-values based on post-hoc LSD. n = 8 animals per group. *: significant, p †0.0125.</p
Contextual fear conditioning in stressed and non-stressed control and MR-tg mice.
<p>Bar graphs represent the results for: (A) freezing time before the foot shock on day 1, (B) freezing time after the foot shock on day 1, and (C) freezing time during the retention test on day 2. Data are expressed as mean + SEM with p-values based on post-hoc LSD. n = 12 mice per group.</p
