Title: Hubbard Brook field weather notes 1990-2019
Hubbard Brook weather notes (aka field notes) are daily weather observations by technicians at Hubbard Brook – a record that began in the mid-1970s, and continues today. Weekend weather notes are included, and are observations from their nearby homes in Thornton, Campton or Plymouth NH. These notes capture subtle details in weather that are not recorded by sensors at Hubbard Brook. These may include, but are not limited to, thunderstorms, frontal passages, named storms (i.e. Hurricanes, Tropical storms), fog, ground surface frost, precipitation type, and cloud types. In this data package, the weather notes from 1990-2019 have been scanned into annual pdf files, and are zipped into 5 year increments for download. Temperature and precipitation data are noted on the weather note sheets – these data are from hygrothermographs and precipitation recording rain gage at STA/RG22 (Hubbard Brook Headquarters), and beginning in 2014-15, from digital sensors. Note that temperature and precipitation from these handwritten sheets should not be used for data analysis. Temperature and precipitation finalized QA/QC products are available in digital format at the links below. The handwritten weather notes should be used as reference only. 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.

    Freshly senesced leaf litter was collected during autumn in New Hampshire at the Bartlett Experimental Forest, Hubbard Brook Experimental Forest, and Jeffers Brook as part of the Multiple Elementation Limitation in Northern Hardwood Ecosystems (MELNHE) study. Leaf litter was collected in October 2021 and 2022 at peak litterfall (i.e., mid-October) during a rain-free period. These leaf-litter samples were analyzed for nutrient concentrations for use in resorption analyses. This dataset includes photos of all of the leaf-litter samples used for chemical analysis. For the corresponding chemistry data, please see the following data package: Zukswert, J., K. Gonzales, S. Hong, C. See, B. Quintero, and R.D. Yanai. 2025.

These leaf litter samples correspond with green foliage samples collected in late July and early August of the same years: the green foliage data can be found in the following data package: Zukswert, J.M., S.D.

    In this study, we analyzed territory sizes of seven migratory songbirds occupying a 10-hectare plot in the Hubbard Brook Experimental Forest, New Hampshire, USA over a 52-year period (1969-2021). All species varied in abundance over the duration of the study, some dramatically. Changes in territory sizes were inversely related to changes in abundance within the study plot despite differences in habitat preference, supporting the ideal free distribution. Territory sizes varied two-fold within a year across species. Results contribute to understanding how variation in territory size relates to 1) how habitat use changes with bird abundance, 2) the evolution of territory size, and 3) the role of territoriality in population dynamics. This dataset includes data, R code, and spatial files supporting this study. 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.
