Abstract In recent decades, the use of satellite sensors, near‐surface cameras, and other remote methods for monitoring vegetation phenology at landscape and higher scales has become increasingly common. These technologies provide a means to determine the timing of phenophases and growing season length at different spatial resolutions; coverage tha...

It is a critical time to reflect on the National Ecological Observatory Network (NEON) science to date as well as envision what research can be done right now with NEON (and other) data and what training is needed to enable a diverse user community. NEON became fully operational in May 2019 and has pivoted from planning and construction to operatio...

Indirect climate effects on tree fecundity that come through variation in size and growth (climate-condition interactions) are not currently part of models used to predict future forests. Trends in species abundances predicted from meta-analyses and species distribution models will be misleading if they depend on the conditions of individuals. Here...

... The use of real-world examples and real ecological data allows students to relate to a sense of place, making the module content much more relevant to students [45]. Our teaching module adds to the growing number of teaching resources which are using NEON data [46], though it is the first, to the best of our knowledge, to use NEON data for teaching forecasting to undergraduates. Moreover, our module can be taught using different modalities (hybrid, virtual, in-person), which provides a flexible approach for integrating NEON data into ecology curricula [47]. ...
... We conducted robustness analyses to verify the effect of vital rate model structure on the output of demographic models and found that the model structure had little influence on the estimates of λ and demographic compensation ( Figure S3 & S4). Since no data on each individual's reproductive state are available, we fixed the reproduction probability to 1 for all size classes because the tree sizes in our study were generally larger than the biological thresholds for most species' reproduction (Clark et al., 2021;Qiu et al., 2021). The size distribution of recruits was described with normal distribution using the empirical mean and standard deviation of the size distribution of recruits in each population. ...
