Data and Code in support of Nitrogen and phosphorus co-limitation of forest growth in northern hardwood forests; Blumenthal et al. 2025
The Multiple Element Limitation in Northern Hardwood Ecosystems (MELNHE) project studies N and P acquisition and limitation of forest productivity through a series of nutrient manipulations in northern hardwood forests. This data set is published in support of a manuscript titled "Nitrogen and phosphorus co-limitation of forest growth in northern hardwood forests" and includes data and code used in the analysis. The primary diameter breast height dataset can be found in: Fisk, M.C., R.D. Yanai, and T.J. Fahey. 2025. Tree DBH response to nitrogen and phosphorus fertilization in the MELNHE study, Hubbard Brook Experimental Forest, Bartlett Experimental Forest, and Jeffers Brook ver 2. Environmental Data Initiative. https://doi.org/10.6073/pasta/fb8f8d5b903627bee9ad6aa4c32f2289. Additional detail on the MELNHE project, including a datatable of site descriptions and a pdf file with the project description and diagram of plot configuration can be found in this data package: https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-hbr&identifier=344 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.
How nitrogen and phosphorus supply to nutrient-limited autotroph communities affects herbivore growth: testing stoichiometric and co-limitation theory across trophic levels
<p><span>Primary producer communities are often growth-limited by essential nutrients such as nitrogen (N) and phosphorus (P). The magnitude of </span><span>limitation and whether N, P, or both elements are limiting autotroph </span><span>growth depends on the supply and ratios of these essential nutrients. </span><span>Previous studies identified single, serial or co-limitation as predominant </span><span>limitation outcomes in autotroph communities by factorial nutrient </span><span>additions. Little is known about potential consequences of such scenarios </span><span>for herbivores and whether their growth is primarily affected by changes </span><span>in autotroph quantity or nutritional quality. We grew a community of </span><span>phytoplankton species differing in various food quality aspects in </span><span>experimental microcosms at varying N and P concentrations resulting in </span><span>three different N:P ratios. At carrying capacity, N, P, both nutrients or </span><span>none were added to reveal which nutrients were limiting. The nutrient supplied </span><span>communities were fed to the generalist herbivorous rotifer </span><span>Brachionus calyciflorus to investigate how changing phytoplankton </span><span>biomass and community composition affect herbivore abundance. We </span><span>found phytoplankton being growth-limited either by N alone (single </span><span>limitation) or serially, i.e. primarily by N and secondarily by P, altering </span><span>available food quantity for rotifers. Rotifer growth showed a different </span><span>response pattern compared to phytoplankton, suggesting that apart from </span><span>food quantity food quality aspects played a substantial role in the </span><span>transfer from primary to secondary production. The combined addition of </span><span>N and P to phytoplankton had generally a positive effect on herbivore </span><span>growth, whereas adding non-limiting nutrients had a rather detrimental </span><span>effect probably due to stoichiometrically imbalanced food in terms of </span><span>nutrient excess. Our experiment shows that adding various nutrients to </span><span>primary producer communities will not always lead to increased </span><span>autotroph and herbivore growth, and that differences between autotroph </span><span>and herbivore responses under co-limiting conditions can be partly well </span><span>explained by concepts of ecological stoichiometry theory.</span></p>

Dietary protein and sodium co-limit cockroach growth and reproduction, 2019-2020
The dataset contains information on a feeding study done on the cockroach species Blaptica dubia. Cockroaches were assigned to a combination of treatments that contained two levels of protein (low 21% or high 27%) and three levels of sodium (low 0.06%, medium 0.15%, or high 0.3%). Cockroaches were reared until reaching maturity, growth measurements were taken every 14 days. Individuals from the same treatment were then paired to reproduce their first clutch of offspring.
