We used the fitted exponential model to estimate the observation error per spotlight transect. The exponential rate of increase (r) over the study period differed markedly between spring :summer and autumn-winter periods, and averaged 2.3 yr(-1) and 2.5 yr(-1) for the 2 sites monitored. A model-selection approach identified a simple exponential population growth model, allowing the observed rate of increase to differ between spring-summer (Aug-Feb) and autumn-winter (Mar-Jul) to be an adequate description of the observed data. trends in spotlight-count data during an 18-month period of increase in European rabbit (Oryctolagus cuniculus) abundance at sites in North Canterbury, New Zealand. We assessed the precision of spotlight-counting as a technique to monitor changes in rabbit abundance by fitting simple population growth models to observed. Reliable estimates of population growth rates and densities are fundamental for effective wildlife management programs. The site, as it contributes to the ecosystem balance in forest plantations. There is a need to initiate the conservation of nocturnal mammals in Indicates high hunting pressure that might primarily cause the observed The high encounter rate of hunters during the study The population density of nocturnal mammals was very The encounter rate with huntersĭuring the night survey were much higher as compared to the observed Results from the diversity index that was obtained from vehicle spotlightĬounts survey was H’=0.56 and 1-D=0.5. Three common palm civets and one smooth tooth palm civet were recorded.
During the vehicle spotlight counts survey, The study wasĬonducted from the 1st -21st August 2015. King’sĬensus method was used to calculate the population density. Using Shannon-Weiner (H’) and Simpson’s Index of Diversity (1-D). Were walk spotlight counts and vehicle spotlight counts. Main objective of this study was to conduct a preliminary assessment of Terrestrial nocturnal mammals in the forest plantations of Acacia mangium, Years in forest plantation establishment. Weight: 8.Biodiversity conservation has been given a significant emphasis in recent.Submersion and Dust Rating: IP68+ equivalent.Tube type: MX-10160 style, Autogain only.It is rugged and has been drop from the NATO 1.5 meter drop test standard onto concrete, as well as meets and exceeds MIL-STD-810G. This unit is light weight without compromising strength. The articulating design also enables users to operate vehicles without limiting head space by eliminating the need to stow the unit upright or to tuck the pods against the helmet when stowed. When assembled to the TAB “Daisho” bridge extra features are enabled such as articulation to the side for single or dual eye use. Push button on/off in the cap to reduce weight and reduce the footprint of the monocular. The Tanto Articulating Bridge will be released at a later date.It is simple with a minimalist lightweight design. The bridge enables the use of a single battery for both tubes, has built in IP stops similar to the UANVB “Katana”, and other features when released.
To transform into the binocular, simply remove the battery cap and battery, insert the bridge into the battery compartment, and tighten the rear clamp screws on the bridge, done. The innovative design allows users to transform their monoculars into an articulating binocular in seconds or go from a binocular back to a monocular to share with a partner. * HOUSING ONLY, NO TUBES OR OPTICS INCLUDED * A unique feature of this monocular is its ability to be adapted to a proprietary powered articulating dual bridge mount called the TAB (Tanto Articulating Bridge) “Daisho” with minimal tools or extra parts. This unit mounts via a standard PVS-14 J-arm mount.
