Reproductive data Fagus sylvatica: Widespread masting breakdown in beech

Climate change effects on tree reproduction are poorly understood even though the resilience of populations relies on sufficient regeneration to balance increasing rates of mortality. Forest-forming tree species often mast, i.e. reproduce through synchronised year-to-year variation in seed production, which improves pollination and reduces seed predation. Recent observations in European beech show, however, that current climate change can dampen interannual variation and synchrony of seed production, and that this masting breakdown drastically reduces the viability of seed crops. Importantly, it is unclear under which conditions masting breakdown occurs, and how widespread breakdown is in this pan-European species. Here, we analysed 50 long-term datasets of population-level seed production, sampled across the distribution of European beech, and identified increasing summer temperatures as the general driver of masting breakdown. Specifically, increases in site-specific mean maximum temperatures during June and July were observed across most of the species range, while the interannual variability of population-level seed production (CVp) decreased. The declines in CVp were greatest where temperatures increased most rapidly. Additionally, the occurrence of crop failures and low-seed years has decreased during the last four decades, signalling altered starvation effects of masting on seed predators. Notably, CVp did not vary among sites according to site mean summer temperature. Instead, masting breakdown occurs in response to warming local temperatures (i.e. increasing relative temperatures), such that the risk is not restricted to populations growing in warm average conditions. As lowered CVp can reduce viable seed production despite the overall increase in seed count, our results warn that a covert mechanism is underway that may hinder the regeneration potential of European beech under climate change, with great potential to alter forest functioning and community dynamics.

Widespread Error Detection in Large Scale Continuous Integration Systems

Dataset of 5000 json documents describing verification process of <a href="https://github.com/facebook/react">React</a> project collected between 2023 and 2024. Errors recorded in this dataset were used in the presentation at CCIW workshop. Abstract: Continuous Integration systems are widely used in the software industry to validate and integrate code changes into central repositories. Their effectiveness can be impacted by non-deterministic tests which can fail in the absence of any regression. Integration tests which depend on external services are particularly prone to this problem. We present a system which allows us to reduce the impact of non-deterministic failures by detecting widespread errors. The key assumption, which works well in practice, is that developers tend not to make identical mistakes simultaneously. If we observe a widespread error, it strongly suggests there is a problem with upstream services and not with the code change being evaluated. The detection algorithm consists of three main phases. First, the error text gets extracted from logs using predefined heuristics or automated methods. Then, this text gets fuzzy matched against a database of recently observed errors. Finally, statistics get checked to determine if they meet the criteria for a widespread error. When an error meets the criteria it either gets demoted to a warning or it gets enriched with information about an ongoing incident.
