The Ecotone company from the Polish Tri-Cities area produces its binoculars in China and Japan and its offer is getting wider and wider. In fact the binoculars can be focused using just one finger and two comfortable central screws.
The Ecotone SR-4 reminds us of the Docter 10x42, the Bresser Montana and the Bushnell Discoverer very much.
It is difficult to tell unambiguously whether or not Ecotone followed the example of Docter.
This site is not responsible for any damage that the information on this site may cause to your system. This project creates a high visibility public infrastructure that addresses the dynamic condition of the greater San Francisco Bay area ecosystem while creating a framework through which users may experience the ever changing local conditions of the site.
Given the increasingly complex shifts being brought upon Bay Area ecologies by global climate change, we believe that landscape itself can be a type of generative “soft” infrastructure, not only capable of fostering local remediation, but acting as an synthetically maintained ecological system which “seeds” other at risk ecological infill sites – re-establishing processes halted by years of development and environmental disruption.
The site is organized and “grown” through the implementation of both Eco-structures and Agri-structures which create a highly concentrated wetland ecotone. Our design research for this project raised some topological questions regarding the role agriculture could play in ecological remediation, what the crossroads of infrastructure and natural systems might be like, the role of education in environmental design, and the true scales of impact local interventions could spark.  These are by no means new questions, but given the current ecological and economic climate, we believe there is (or should be) a growing imperative towards open-ended, globally aware, locally sited design solutions. As we continue our research, we will document its progress on our blog – hoping to augment our findings through discussion and participation.  We hope you enjoy putting forward whatever thoughtful insights, comments, criticisms, or resources you might have.

Since observations began in 1982, Arctic tundra vegetation productivity (greenness) has increased, monotonically in Eurasia and at an accelerated rate since 2005-09 in North America. The length of the growing season (photosynthetically active period) has increased by 9 days per decade since 1982. Tall shrubs and trees have expanded their range across the forest-tundra ecotone in Siberia, with areal expansion rates of up to 25% since the mid- to late-1960s. The number and severity of tundra wildfires on the North Slope of Alaska has increased dramatically during the last decade. Vegetation productivity (greenness) trends for the arctic tundra have been updated for the period 1982-2012 using the Global Inventory Modeling and Mapping Studies (GIMMS) Maximum Normalized Difference Vegetation Index (MaxNDVI, no units) from the Advanced Very High Resolution Radiometer (AVHRR).
NDVI is often positively related to summer temperature, as indicated in a recent synthesis by Post et al.
The length of the growing season (photosynthetically active period, PAP) in the Arctic has increased by 9 days per decade since 1982 (Xu et al.
Numerous studies over the past decade have indicated the expansion of shrubs throughout the Arctic (Isla Myers-Smith 2011) and experiments continue to show that warming increases vegetation productivity and the dominance of woody plants (Sistla et al. Historically, wildfires have been rare in the Arctic, although they are a dominant feature of the boreal forests south of the Arctic tundra.
The recent, 2007, Anaktuvuk River wildfire, burned >1000 km2 of tundra about 40 km north of Toolik Lake on the North Slope of Alaska, and alone accounts for over half of the area burned on the North Slope since 1950. Recovery of the vegetation canopy and concomitant surface energy exchange has been quite rapid in the region of the Anaktuvuk River fire, as indicated by a soil and plant biomass harvest conducted in 2011 at the burn site, which included areas that had not been burned, or were moderately or severely burned (Rocha et al. Colleen Cooley is considering whether she will return to the Navajo reservation after she finishes college. Hopi elder and artist Bob Lomadofkie works with Northern Arizona University to provide guidance and mentoring for Native American students. Northern Arizona University classmates: Stephanie Jackson (from left), Vachera Yazzie, Philan Tree and Colleen Cooley.
One of more interesting offers, launched on the market in 2005, was the Ecotone SR-4 10x42 binoculars.
All of them have similar, quite significant weight, compact and solid housing, identical focusing system, wide field of view and minimal focus distance; the slip-ups are also the same - false pupils and the lack of a tripod exit.


Even if it was the case, though, the student got better than the master in some categories and the copy was proven to be better than the original thing. Katharyn Boyer, the project’s two major functions are the replenishment of native eelgrass, and the production of critical natural resources to be used in a larger Bay-Wide remediation scheme. These structures include redistributed land form, low-impact access catwalks, and distribution networks – together generating a site-wide “Plot” nursery for desperately needed habitats and endangered native species. We want to rethink the idea of “public works” as a typically large, disruptive, and costly endeavor now replaced by smaller scale “soft” networks created through the exchange between a variety of fields, including  architecture, landscape, environmental design, civil engineering, urban planning, logistics, social advocacy, and community leadership.
Mature impala males are territorial, and they attract herds of females and young to their territories. Since the 2007 Anaktuvuk River fire, above-ground net primary productivity has been greater on moderately burned sites than sites that did not burn. MaxNDVI (NDVI at the peak of the growing season) trends from 1982 to 2012 are broadly positive, with exceptions in northwestern Siberia, eastern Russia and western Alaska (Fig. One result of the fire was a huge emission of soil carbon, approximately 2.1 Tg, effectively equivalent to the present-day annual uptake (sink) of the entire global arctic tundra biome (Mack et al. Jia, 2013: Impacts of snow cover on vegetation phenology in the Arctic from satellite view. The series profiles American Indians and non-Indians who live in northern Arizona communities that border the Navajo and Hopi reservations.

The Ecotone corrects the chromatic aberration better and has a sharper field of view edge, most probably because of the usage of the low-dispersion glass.

Trend of change (in %) in annual MaxNDVI between 1982 and 2012 calculated using a least squares regression at each pixel (from Bhatt et al. Few observations of woody plant expansion had been made in Siberia until Frost and Epstein (2013) quantified changes in tall shrub and tree canopy cover in eleven, widely-distributed Siberian forest-tundra ecotone landscapes. Tall shrub and tree expansion at the forest-tundra ecotone in Siberia since the mid- to late-1960s (from Frost and Epstein 2013). The results suggest that the vegetation, particularly the graminoids (dominated by the tussock-forming sedge Eriophorum vaginatum), was able to regrow relatively quickly from below-ground rhizomes, with above-ground net primary productivity of the moderately burned tundra being slightly greater than in tundra that had not been burned (Fig.

The surplus production of the Plots is exported to other sites as they become available due to rising sea levels. To better understand the trends, break points in the time series were quantified using the Breakfit algorithm (Mudelsee 2009).
Trend lines with break points and associated errors are show for each time series together with the slopes before (top left) and after (top right) the break points (Bhatt et al. Snow cover variability is considered to be an important cause of such phenological change in Arctic tundra. Within expanding and newly-established shrub stands, almost all new shrubs occurred on bare, circular microsites disturbed by seasonal frost-heave, a widespread phenomenon that maintains mosaics of mineral seedbeds with warm soils and few competitors. All of the above-ground vegetation was burned, and there were major increases in energy inputs (radiative forcing) to the system and other changes such as large increases in depth of soil thaw. Zetterberg, 2010: Russian Arctic warming and 'greening' are closely tracked by tundra shrub willows.


Te Schmidt- Pechan system prisms are phase correction coated and the reflecting surface was covered not by ordinary aluminum but by silver. Also a clash with the Bushnell Discoverer must be won by the Ecotone because the score is practically the same but the price of the Ecotone – lower by more than 100 USD.

This group is right along the edge between a grassy patch that was recently burned by park managers and a shrubby savanna patch.
MaxNDVI has increased monotonically in Eurasia since 1984, and at accelerated rates since 2005 and 2009 in western North America and eastern North America, respectively (Fig.
The bare circles of mineral soil are immediately available to shrubs during favorable climatic periods. Kumpula, 2012: Eurasian Arctic greening reveals teleconnections and the potential for structurally novel ecosystems.
The producer decided to use low-dispersion glass in the construction which is supposed to ensure excellent chromatic and spherical aberration correction.

Alder abundance and extent have likely increased rapidly in the northwest Siberian Low Arctic since at least the mid-20th century, and this region has high potential for continued expansion of tall shrubs due to the broad distribution of patterned-ground landscapes. However, lichens and mosses are showing little sign of recovery, and shrub wood was lost in the fire. Additionally all the air-to-glass surfaces in the binoculars were covered by high quality antireflection coatings.
For example, large-scale atmospheric circulation is likely a key contributor to lower temperatures and more consistent greening over Eurasia through increased summer cloud cover, compared to the accelerated greening in North America under more cloud-free skies (Bhatt et al. Therefore, the total biomass of the vegetation is substantially lower in the burned areas than those that did not burn.
