(2025) claim that large-carnivore recovery in Yellowstone National Park has produced a strong trophic cascade compared to other systems, citing a 152-fold increase in aspen sapling density and widespread recruitment of new trees. We show that these conclusions substantially overstate the cascade’s strength because of key methodological and interpretive flaws. First, Painter et al. miscalculated the baseline density in their dataset, inflating the reported log response ratio from a true 17.5-fold increase to 152-fold. Second, they analyzed repeated measurements of the same stands as if they were independent samples, overstating standardized effect sizes by 30–40 %. Third, because sapling densities are highly zero-inflated and right-skewed, mean-based metrics (log response ratios and standardized differences) are disproportionately influenced by a small minority of plots, while most plots showed little or no change. Fourth, Painter et al. conflated stand-level occurrence with magnitude, treating the presence of one or a few tall stems (“43 % of stands contained small trees”) as evidence of widespread recruitment. Finally, their assumptions that stems ≥ 2 m have escaped browsing and that reduced browsing alone drives height growth are contradicted by long-term data showing substantial browsing through 2–2.5 m and strong height–browsing feedbacks. Taken together, these shortcomings exaggerate the magnitude and pace of aspen recovery. The evidence supports the occurrence of a trophic cascade in Yellowstone, but not the magnitude of strength claimed. Accurate assessment of trophic cascade strength in Yellowstone is vital to ensure that this iconic system reliably informs ecological understanding and restoration practice.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"605 ","pages":"Article 123448"},"PeriodicalIF":3.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146188566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The significance of clearcutting stems from its monotonic increase over time due to being a cumulative sum, which cannot be distinguished statistically from a spurious correlation in a single-site time series. Adding the observation year as an additional explanatory variable to the original model made the significance disappear and changed the sign of the coefficient, indicating confounding with time. A comparison with alternative time-aware modeling approaches also reduced support for clearcutting as a primary driver. As in the original study, seasonal temperature values were significant explanatory variables of changes in bird densities, supporting climate-linked trends. Including temporal structure (autoregression and moving average terms) and species interactions could improve the model’s ability to describe the bird population drivers. However, any such inference is inherently limited by the data. The lack of replication, potential observer bias over the 30-year period, spatial inconsistencies, and unresolved issues in the clearcut dataset raise concerns.

We analysed 16 chronosequences spanning five successional stages, from meadows and pastures to mature forests (up to ∼75 years since abandonment), organized into four clusters along a latitudinal gradient in Italy, encompassing the Alpine, Continental, and Mediterranean biogeographical regions. We quantified vegetation, deadwood, and soil C pools and calculated diversity indices for herbaceous plant species. Linear and generalized linear mixed models were used to assess successional stage and site effects on C stocks and diversity indices. Total ecosystem C increased along succession, driven primarily by tree biomass, reaching 195–289 Mg C ha⁻¹ in late-successional forests. Soil C showed no clear successional trend, with weak or site-specific patterns. Herbaceous species richness and diversity peaked in managed meadows/pastures and early encroachment stages but declined towards closed-canopy forests in three sites. By contrast, a U-shaped pattern emerged in the southernmost site. Consequently, the C–diversity relationship was predominantly negative, except for the non-linear response observed in the Mediterranean site. Overall, spontaneous reforestation promotes C storage but often reduce herbaceous plant diversity, revealing potential trade-offs between climate mitigation and plant diversity.

Satellite-based remote sensing is an effective method to assess post-fire forest conditions. Traditionally, differenced satellite-derived burn severity indices are computed by differencing one year pre- and post-fire spectral reflectance values. Differenced burn severity indices are useful for quantifying and mapping the magnitude of ecological change, but their application to detecting and mapping post-fire live trees may not be as appropriate, particularly for delayed tree mortality. Delayed tree mortality (“delayed mortality”) is a phenomenon where trees that initially survive fire then die over an extended period (between one and five years), and it can be challenging to measure and predict. In this study, we demonstrate the potential of mapping delayed mortality using readily available remotely sensed imagery alone. We used random forest models to detect post-fire live trees using 10-m resolution Sentinel-2 data at one-, three-, and five-years post-fire for four fires in the southern Sierra Nevada, California, USA. Using imagery from the National Agriculture Imagery Program (NAIP; 60-cm resolution), we manually classified live tree presence in 6000 Sentinel-2 pixels (500 pixels for each fire-year combination) to calibrate and validate models. Sentinel-2 based model accuracies ranged from 65 % to 86 % with F-scores ranging from 0.52 to 0.86, and their predictions of live pixel area were on average 44 % lower than inferred from more traditional indices such as relative differenced normalized burn ratio (RdNBR).

Although the diets of moose vary spatially and seasonally, they predominantly consist of woody perennials such as <em>Betula</em> spp., <em>Populus</em> spp., <em>Salix</em> spp., and <em>Abies</em> spp. but also herbaceous and aquatic plants, that can all be impacted by forest management. Because moose diets vary across their range and seasonally, understanding their local diet composition is crucial for guiding land management decisions that may affect moose range quality and population dynamics. This study aimed to determine the vascular plant species composition in the diets of moose in selected locations of north-central British Columbia (BC), Canada, where moose populations have been declining and to examine how their diets varied geographically, annually (from one summer to the next), and within season (from early to late summer). During the summers of 2020, 2021, and 2022, moose fecal samples were collected from three areas in north-central BC known to be occupied in summer by moose and analyzed with DNA metabarcoding using a technique employing the second internal transcribed spacer (ITS2) to determine the plant species composition in the collected fecal samples. Frequencies of identified plants from 14 families and 18 genera were separately compared across space and time using Frequency of Occurrence, Relative Read Abundance, Pianka’s Niche Overlap Index, and two-sided Fisher’s exact tests. The diversity of plants in the diet was also compared. Most of the identified taxa fell into 5 families: Onagraceae, Betulaceae, Grossulariaceae, Rosaceae, and Ericaceae. Results indicated considerable variation in diet between geographical areas with low variation in diet between years and a need for increased sampling effort within early and late seasons.

Here, we investigated shifts in soil microbial community, chemical properties, and extracellular enzyme activities across a chronosequence of <em>Cunninghamia lanceolata</em> plantations aged 5–60 years. Our findings demonstrated that the Shannon diversity indices of both bacteria and fungi, along with the abundances of bacteria and fungi exhibited age-associated fluctuations. Fungal community composition exhibited differences between young with half-mature stages (5–20 years) and near-mature with mature stages (25–35 years), while that of bacteria displayed differences between young with half-mature stages (5–20 years) and overmature stages (41–60 years). Specifically, young and over-mature forests promoted oligotrophic and pathogenic taxa (i.e. class of <em>Ustilaginomycetes</em> and <em>Dothideomycetes,</em> and <em>Chloroflexi</em> phylum), while middle-aged stands enriched copiotrophic groups (i.e. phylum of <em>Mortierellomycota</em> and <em>Rozellomycota</em>).

The proposed mechanism suggests that the fluctuations in NH₄⁺-N content driven by forest aging negatively influences soil pH, which subsequently lowers bacterial Shannon index and abundances of microorganisms secreting alkaline phosphatase, thereby reducing the availability of available phosphorus.
