Tropical mountain forests are important biodiversity hotspots, which host disproportionally high number of endemic species. However, the potential impacts climate change in these areas uncertain. A key factor contributing to this knowledge gap is that climatic conditions experienced by organisms inside tropical (i.e., microclimate) remain largely understudied. Due effects topography and vegetation, understory microclimate can differ substantially from free-air macroclimate). This study aimed at unveiling vegetation structural characteristics microclimatic patterns along an elevational gradient a highly diverse ecosystem (Mount Kenya), combining hundreds terrestrial laser scanning measurements with two-year time-series observations. Our results showed macroclimate temperature elevation contributed >90 % variability our area. The influence soil moisture regulating differed between day night, as well different periods year. contribution variation during was two times higher than night. Soil had cooling effect on daytime, while opposite pattern observed These differences affected lapse rates, clearly seasonal fluctuation diurnal but relatively stable night periods. range regulated combined structure, elevation, moisture.

Summary Forests harbour large spatiotemporal heterogeneity in canopy structure. This variation drives the microclimate and light availability at forest floor. So far, we do not know how sub‐canopy temperature interactively mediate impact of macroclimate warming on understorey communities. We therefore assessed functional response plant communities to addition a full factorial experiment installed temperate deciduous forests across Europe along natural microclimate, gradients. Furthermore, related these responses species’ life‐history syndromes thermal niches. found no significant community treatment.

Microclimate varies greatly over short horizontal and vertical distances, timescales. This multi-level heterogeneity influences terrestrial biodiversity ecosystem functions by determining the ambient environment where organisms live in. Fine-scale in microclimate temperatures is driven local topography, land water cover, snow, soil characteristics. However, their relative influence boreal tundra biomes different seasons, has not been comprehensively quantified. Here, we aim to (1) quantify temperature variations measured at three heights: (-6 cm), near-surface (15 cm) air (150 (2) determine of environmental variables driving thermal variability. We 446 sites within seven focus areas covering large macroclimatic, topographic, gradients (tundra, mires, forests) northern Europe. Our data, consisting 60 million readings during study period 2019/11–2020/10, reveal substantial variability across areas. Near-surface showed greatest instantaneous differences a given area (32.3 °C) while corresponding for ranged from 10.0 °C (middle forest) 27.1 (tundra). Instantaneous wintertime were largest (up 25.6°C, median 4.2 °C), summer southern forest (13.1°C, 4.8°C). Statistical analyses indicate that monthly-aggregated forests are closely linked bodies, wetlands, canopy whereas tundra, variation was elevation, topographic solar radiation, snow cover. The results provide new understanding on magnitude its seasonal drivers will help project impacts climate change ecosystems.

Abstract Invasive species pose a major threat to biodiversity and inflict massive economic costs. Effective management of bio-invasions depends on reliable predictions areas at risk invasion, as they allow early invader detection rapid responses. Yet, considerable uncertainty remains how predict best potential invasive distribution ranges. Using set mainly (sub)tropical birds introduced Europe, we show that the true extent geographical area invasion can accurately be determined by using ecophysiological mechanistic models quantify species’ fundamental thermal niches. Potential ranges are primarily constrained functional traits related body allometry temperature, metabolic rates, feather insulation. Given their capacity identify tolerable climates outside contemporary realized niches, well suited for informing effective policy aimed preventing escalating impacts species.

Abstract Microclimates have been recognised as one of the key drivers in global change biology. Durable microclimate loggers, detailed in‐situ measurements and sophisticated modelling tools are increasingly available, but a lack standardised workflows for data handling hinders synthesis across studies thus progress To overcome these limitations, we developed an R package myClim processing, storage analyses. The supports complete workflow handling, including reading raw logger files, their preprocessing cleaning, time‐series' aggregation, calculation ecologically relevant microclimatic variables, export storage. stores size‐efficient, hierarchical structure which respects hierarchy field measurement (locality > loggers sensors).

Understanding how environmental factors affect the thermal tolerance of species is crucial for predicting impact stress on abundance and distribution. To date, species' responses to are typically assessed laboratory-reared individuals using coarse, low-resolution, climate data that may not reflect microhabitat dynamics at a relevant scale. Here, we examine daily temporal variation in heat range their natural environments across temperate tropical Australia. Individuals were collected habitats throughout day tested immediately thereafter, while local microclimates recorded collection sites. We found high levels plasticity all species. Both short- long-term variability temperature humidity affected plastic adjustments within days, but with differences. Our results reveal changes occur rapidly scale relatively short timescale important drivers observed tolerance. Ignoring such fine-scale physiological processes distribution models might obscure conclusions about shifts global change. This article part theme issue ‘Species’ ranges face changing (part 1)’.
