Extreme Heatwave Causes Immediate, Widespread Mortality of Forest Canopy Foliage, Highlighting Modes of Forest Sensitivity to Extreme Heat Open
In late June 2021, multiple days of record‐breaking heat caused an unprecedented amount of foliage death in the forests of the Pacific Northwest, USA. Portions of tree canopies with healthy green foliage prior to the heat changed to red or…

Analogous Environments Across the Tropics Have Similar Levels of Tree Species Αlpha Diversity Open
Different regions of the tropics vary in overall tree species diversity, with the tropical Americas exhibiting strikingly higher regional tree species richness than Africa and Southeast Asia. We investigated whether these differences also …

Leveraging long‐term data to improve biodiversity monitoring with species distribution models Open
Correlative species distribution models (SDMs) are essential tools in conservation biology, global change assessment and reserve prioritization, linking species occurrences with environmental conditions. These models often rely on coarse‐s…

Microclimate Refugia Are Transient in Stable Old Forests, Pacific Northwest, USA Open
An issue of global concern is how climate change forcing is transmitted to ecosystems. Forest ecosystems in mountain landscapes may demonstrate buffering and perhaps decoupling of long‐term rates of temperature change, because vegetation, …

Co‐mast: Harmonized seed production data for woody plants across <span>US</span> long‐term research sites Open
Plants display a range of temporal patterns of inter‐annual reproduction, from relatively constant seed production to “mast seeding,” the synchronized and highly variable interannual seed production of plants within a population. Previous …

Community Synchrony in Seed Production is Associated With Trait Similarity and Climate Across North America Open
Mast seeding, the synchronous and highly variable production of seed crops by perennial plants, is a population‐level phenomenon and has cascading effects in ecosystems. Mast seeding studies are typically conducted at the population/specie…

Wind dispersed tree species have greater maximum height Open
Aim We test the hypothesis that wind dispersal is more common among emergent tree species given that being tall increases the likelihood of effective seed dispersal. Location Americas, Africa and the Asia‐Pacific. Time period 1970–2020. Ma…

LLM360: Towards Fully Transparent Open-Source LLMs Open
The recent surge in open-source Large Language Models (LLMs), such as LLaMA, Falcon, and Mistral, provides diverse options for AI practitioners and researchers. However, most LLMs have only released partial artifacts, such as the final mod…

Assessing spatiotemporal resolution of variables in landscape-scale species distribution models Open
The strategic importance of biodiversity conservation is increasing all over the world to face the threats that the global change bring to forest ecosystems. To accomplish that, Species Distribution Models (SDMs) stand as the most employed…

Increasing Daytime Stability Enhances Downslope Moisture Transport in the Subcanopy of an Even‐Aged Conifer Forest in Western Oregon, USA Open
Mountain breezes, including katabatic and anabatic flows, and temperature inversions are common features of forested mountain landscapes. However, the effects of mountain breezes on moisture transport in forests and implications for region…

A long‐term perspective on microclimate and spring plant phenology in the Western Cascades Open
Phenology—recurring seasonal events in an organism's life cycle—is largely driven by local climates <1 km 2 (microclimates), and changes in phenology are frequently used to indicate a species’ or community response to climate change. Pheno…

Climate seasonality limits leaf carbon assimilation and wood productivity in tropical forests Open
The seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combination of season…
