“…Stand age was generally younger in the Tug Hill than Adirondacks (McGee et al 1999, Pan et al 2011), with a greater proportion of public land protected from development in the Adirondacks (i.e., Adirondack Park; Kretser et al 2008). Herbaceous understory coverage was variable in northern New York, and could be negatively associated with high‐density overstory, which was more common in unharvested stands (Woodcock et al 2008). On average, vegetation leaf out began slightly earlier in the Tug Hill study area (17–28 April) than in the Central Adirondacks study area (20 April–7 May; USA National Phenology Network 2017).…”

Camera traps are often used to monitor wildlife occupancy and, increasingly, to record life history events. For tree‐denning species such as fishers (Pekania pennanti), camera traps have been used to investigate reproduction (e.g., litter size and kit survival) by documenting females with kits as they move between trees. Yet, unbiased quantification of litter size and kit survival likely requires consideration of detection probability during transitions. We conducted a field experiment with the objective of estimating detection probability of fishers coming to or going from a central tree given different camera arrays and compared that to observations of collared females denning in northern New York. We estimated detection probability via logistic regression and investigated the effects of movement differences related to leaving vs. returning to the tree, as well as temporal effects related to kit development. The number of cameras deployed strongly influenced detection probability, which on average ranged from 0.21 with one camera to 0.85 with 6 cameras, yet detection rate of fishers returning to the den was consistently higher than fishers leaving. Despite the difference in detection relative to direction, we obtained at least one photo of 94% of expected kit transfers. Our results demonstrate the benefits and challenges of purpose‐specific tests when using camera traps for estimating demographic rates, and we offer considerations for researchers that may be considering trade‐offs between number of cameras and different collar technology in understanding reproductive ecology of fishers and similar arboreal‐denning carnivores.

Invasive Hieracium plant species are invading the Greater Yellowstone Ecosystem. The potential distribution of orange hawkweed (Hieracium aurantiacum) and meadow hawkweed (Hieracium caespitosum) were estimated using habitat susceptibility models to assist land managers’ management of these invasive plants. The objectives of this study were to: (1) develop models describing susceptibility of ecosystems to hawkweed invasion, (2) identify indicator species of orange hawkweed and meadow hawkweed, (3) determine habitat types where these invasive hawkweeds might occur, and (4) create habitat susceptibility maps for management planning and ground surveys. Models were developed using a Mahalanobis distance similarity technique from remotely sensed biotic and abiotic variables, as well as known location data for orange and meadow hawkweed. Ground validation was conducted to assess model weaknesses and subsequent model modification. Indicator plant species were identified as surrogates to determine the likelihood of hawkweed presence during ground survey. Transect data collected from areas susceptible to invasion also were used to determine habitat types where hawkweed might occur. The best model included eight variables: north–south aspect, east–west aspect, slope, NDVI, NDWI, blue spectral band, green spectral band, and precipitation. High susceptibility (65 + % likelihood of suitable habitat) consisted of 66,000 ha for meadow hawkweed and 35,000 ha for orange hawkweed, 5.0% and 2.7% of the study area, respectively. Meadow hawkweed and orange hawkweed had seven and three indicator plant species, respectively. Predicted hawkweed habitat susceptibility encompassed nine habitat types, ranging from xeric sagebrush steppe to wet forests and they overlapped except at the xeric habitat type. Habitat susceptibility models save costs and allow survey prioritization to those areas most susceptible to invasion.

The value of pollination to human society is not limited to agricultural production, but also in the sustainability of ecosystems and the services that they provide. Seed set can be used as a comparative measure of pollination effectiveness, with minimum variability expected when other resources are not limiting. Six species of self-incompatible fall asters (Symphyotrichum) were used to evaluate pollination service at 12 sites across a spectrum of expected levels of pollination. Seed set per inflorescence was generally lower at sites with lower pollinator numbers and diversity, although as expected pollinator assemblage characteristics were highly variable within and between sites. However, rankings of sites showed consistency of response across phytometer species and between years; the summed ranks across multiple species appears to have as the greatest value in Pollination Service Measurement (PSM). Abundance, richness, and Shannon diversity of pollinator assemblages were highly autocorrelated and showed variable relationships with seed set depending on plant species and temporal scale of pollinator assemblage assessment. Use of seed set to directly measure pollination service at a site was consistent and cost effective when compared to less certain and more labour-intensive methods of pollinator collection and identification, and shows promise for implementation in pollination monitoring and bioassessment practices.
