Data for 'Weak latitudinal gradients in insect herbivory for dominant rangeland grasses of North America'
Data for Kent et al. Accepted manuscript in Ecology and Evolution, with abstract: Patterns of insect herbivory may follow predictable geographical gradients, with greater herbivory at low latitudes. However, biogeographic studies of insect herbivory often do not account for multiple abiotic factors (e.g. precipitation, soil nutrients) that could underlie gradients. We tested for latitudinal clines in insect herbivory as well as climatic, edaphic, and trait-based drivers of herbivory. We quantified herbivory on five dominant grass species over 23 sites across the Great Plains, USA. We examined the importance of climate, edaphic factors, and traits as correlates of herbivory. Herbivory increased at low latitudes when all grass species were analysed together and for two grass species individually, while two other grasses trended in this direction. Higher precipitation was related to more herbivory for two species but less herbivory for a different species, while higher specific root length was related to more herbivory for one species and less herbivory for a different species. Taken together, results highlight that climate and trait-based correlates of herbivory can be highly contextual and species specific. Patterns of insect herbivory on dominant grasses supports the hypothesis that herbivory increases towards lower latitudes, though weakly, and indicates that climate change may have species-specific effects on plant-herbivore interactions.
Mechanisms influencing physically sequestered soil carbon in temperate restored grasslands in South Africa and North America
This dataset contains a measurement of physically protected carbon (microaggregate-within-macroaggregate C) and potential drivers of physically protected C accumulation during grassland restoration. The data were collected from three independent grassland restorations from agriculture in North America and South Africa. Northeast Kansas, USA data were collected in May 2013. Northeast Free State, RSA data were collected in September–November 2005. Southeast Nebraska, USA data were collected in October 2008–May 2008. Aggregate fractionations were performed by hierarchical wet sieving (Six et al 2000). Carbon and N quantification were done by flash combustion-gas chromatography. Microbial biomass C quantification was performed with chloroform fumigation-incubation (chloroform fumigation-extraction in the case of northeast Kansas). Phospholipid fatty acid biomass analysis was conducted using the methods of Bligh and Dyer (1959).
Daily water temperature and dissolved oxygen data in summer months from 2011 to 2015 for Lake Lillinonah in Northeastern North America
This dataset was used in the analysis described in the manuscript by Macuch, C. & J. Klug. 2020. High-Frequency Temperature and Oxygen Data Reveal the Potential for Stressful Fish Conditions in a Southern New England Impoundment. Northeastern Naturalist 27(3): 520-533. We include high-frequency dissolved oxygen and water temperature data from Lake Lillinonah in Northeastern North America. These data were collected using in situ, automated monitoring sensors deployed each year into the lake in the spring or early summer months. Data were collected from 07 July 2011 through 14 October 2015. These data were used to assess conditions in the lake as they relate to specific stress thresholds for Northern Pike and Largemouth Bass. We found that summer water temperature was nearly always in an acceptable range for Largemouth Bass growth but was frequently in the stressful range for Northern Pike growth. Dissolved oxygen data show consistent hypoxia at the bottom of the lake during some summers, reducing the potential thermal refuge.

Journey North - Hummingbird observations by volunteer community scientists across Central and North America (1996-2020)
This data package contains hummingbird migration data (1996 - 2020) across North and Central America collected by 30,703 community scientists for Journey North, a crowdsourced participatory science program of the University of Wisconsin-Madison Arboretum. The Journey North Hummingbird Project is an ongoing study of hummingbird phenology conducted at broad spatial and temporal scales. Since 1996, community scientists have tracked first arrival dates and breeding and feeding behavior as well as the onset of fall migration and presence of hummingbird species throughout the winter months in the United States. Focal species are the Ruby-throated Hummingbird (Archilochus colubris) and Rufous Hummingbird. However, observational data is also available for Broad-tailed Hummingbird (Selasphorus platycercus), Black-chinned Hummingbird (Archilochus alexandri), Calliope Hummingbird (Selasphorus calliope), Costa's Hummingbird (Calypte costae), Anna’s Hummingbird (Calypte anna), Allen’s Hummingbird (Selasphours sasin). Observers also provide estimates of the number of birds sighted. However, observers do not follow standardized methods for counting species observed. Observers do not observe at set times of the day, do not repeat observations regularly, and are not required to provide the length of time during which a specified number of species observed were counted. Therefore, it is recommended that this dataset be analyzed to indicate presence, not abundance. Additional contextual information is provided as text in the comments field of the dataset. The Journey North Hummingbird Project dataset is hosted by the University of Wisconsin-Madison Shared Web Hosting Service.
Journey North - Monarch Butterfly and Milkweed observations by volunteer community scientists across Central and North America (1996-2020)
This data package contains monarch migration data (1996 - 2020) across North America collected by 42,518 community scientists for Journey North, a crowdsourced participatory science program of the University of Wisconsin-Madison Arboretum. The Journey North Monarch and Milkweed project is an ongoing study of monarch migration phenology conducted at broad spatial and temporal scales. Since 1996, community scientists have tracked first arrival dates and breeding and feeding behavior as well as the onset of fall migration, fall roosts, and peak migration events. Community scientists have also tracked the first emergence of milkweed in the spring and the presence of milkweed across the landscape during the summer, fall-winter months. The focal species is the Monarch Butterfly, Danaus plexippus. Community scientists indicate when known milkweed species in submitted comments. Journey North data is observational and often opportunistic in nature. Observers do provide estimates of the number of adult monarch butterflies sighted during an observation. However, observers do not follow standardized methods for counting species observed. Observers do not observe at set times of the day; do not repeat observations regularly, and are not required to provide the length of time during which a specified number of species observed were counted. Therefore, it is recommended that this dataset be analyzed to indicate presence, not abundance. Additional contextual information is provided as text in the comments field of the dataset.
