Abstract:

Large-scale disturbances such as ice storms may increase in frequency and intensity as climate changes. While disturbances are a natural component of forest ecosystems, climatically driven alteration to historical patterns may impart fundamental change to ecosystem function. At Hubbard Brook Experimental Forest, NH, experimental ice storms of varying severity were applied to replicate plots of mature northern hardwoods to quantify their effects on forested ecosystems. We assessed ice storm treatment effects on insectivorous foliage-gleaning birds and their interactions with larval Lepidoptera. These birds are charismatic, of conservation concern, and are a major predator of caterpillars. In turn, lepidopterans are the dominant herbivores in temperate forests and are integral to ecosystem function. We predicted that avian abundance would increase due to additional structural heterogeneity caused by ice treatments, with a concomitant increase in caterpillar predation.

Point counts were used to measure insectivorous bird activity in the ice storm experiment plots and additional control plots before and after treatments. Point counts were conducted in June 2015 and June 2016. Icing occurred in January-February 2016. We deployed and retrieved plasticine model caterpillars and estimated predation from characteristic marks to these surrogates. Abundance of foliage-gleaning birds was higher in the ice storm plots and birds responded to treatments as a single diffuse disturbance rather than on an individual plot level. All species except one were observed both before and after the ice treatments. Surprisingly, predation on caterpillar models was unaffected by ice storm treatments but rather was a function of caterpillar density. The increase in avian abundance in the ice storm treatment plots corroborates other studies of bird responses to relatively small-scale disturbances in forests and the limited change in species composition was expected given the plot size. We conclude that ice storms may provide beneficial changes for foliage-gleaning birds in the growing season following the disturbance.

A complete analysis of these data can be found in: Leuenberger, W. M. (2017). Response of larval lepidoptera and their avian predators to experimental ice storms in a northeastern forest (Order No. 10282770). Available from ProQuest Dissertations & Theses A&I. (1950488566).

These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.

Methods and protocols used in the collection of this data package
Description:

We conducted point count surveys to estimate an index of insectivorous bird activity in plots (Petit et al., 1995; Farnsworth et al., 2005). Each plot was visited twice per week from 1 June – 21 June 2016 for a total of six visits per plot per year. All plots were surveyed with 15-m fixed radius point counts. Point counts were conducted from the plot center. We approached the point with minimal disturbance and waited one minute before beginning a ten-minute point count. We identified each individual bird seen or heard during the point count. Multiple individuals of the same species were only recorded when clear evidence of counter-calling occurred (hearing 2+ individuals from different directions in a short span of time). Each round of point counts took place over two mornings, with the 11 ice storm plots on one morning and the six edge effects plots on another morning. All point counts were conducted between sunrise and 0845 hours EST. Point counts were conducted prior to 0800 hours on 96% of counts and in the first hour and half following sunrise (0505 – 0635 hours) on 53% of counts. Plot order was reversed on every other visit. Start time, precipitation (none, fog, mist, light rain), cloud cover (0, 25, 50, 75, or 100%), and wind on the Beaufort scale (0 – 5) were recorded during every count. Counts were only conducted under suitable weather conditions for birds (no heavy rain, winds, or storms).
