Extreme and Highly Heterogeneous Microclimates in Selectively Logged Tropical Forests

Frontiers in Forests and Global Change, Journal Year: 2018, Volume and Issue: 1

Published: Oct. 26, 2018

Microclimate within forests influences ecosystem fluxes and demographic rates. Anthropogenic disturbances such as selective logging can affect within-forest microclimate through effects on forest structure, leading to indirect beyond the immediate impact of logging. However, scope predictability these remains poorly understood. Here we use a thermal proxy (sensitive radiative, convective, conductive heat fluxes) measured at floor in three 1-ha plots spanning intensity gradient Malaysian Borneo. We show 1) that ranges spatiotemporal heterogeneity are doubled between old growth heavily logged forests, with extremes often exceeding 45°C, 2) nearby weather station air temperatures provide estimates maximum values biased down by 5-10°C, 3) lower canopy density, higher height, biomass removal associated temperatures. Thus, less buffered from regional climate change than experience much heterogeneity. Better predicting linkages its will be critical for understanding wide range conditions experienced tropical forests.

Localised climate change defines ant communities in human‐modified tropical landscapes

Functional Ecology, Journal Year: 2020, Volume and Issue: 35(5), P. 1094 - 1108

Published: Dec. 7, 2020

Abstract Logging and habitat conversion create hotter microclimates in tropical forest landscapes, representing a powerful form of localised anthropogenic climate change. It is widely believed that these emergent conditions are responsible for driving changes communities organisms found modified forests, although the empirical evidence base this lacking. Here we investigated how interactions between physiological traits genera environmental temperatures they experience lead to functional compositional ants, key organism ecosystems. We abundance activity ant along gradient disturbance Sabah, Malaysian Borneo, was defined by an interaction their thermal tolerance (CT max ) temperature. In more disturbed, warmer habitats, with high CT had increased relative activity, those low decreased activity. This determined primary logged differed daily maximum temperature modest 1.1°C, strengthened as change microclimate disturbance.

Effects of plant diversity, soil microbial diversity, and network complexity on ecosystem multifunctionality in a tropical rainforest

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: Sept. 18, 2023

Introduction Plant diversity and soil microbial are important driving factors in sustaining ecosystem multifunctionality (EMF) terrestrial ecosystems. However, little is known about the relative importance of plant diversity, network complexity to EMF tropical rainforests. Methods This study took rainforest Xishuangbanna, Yunnan Province, China as research object, quantified various functions such organic carbon stock, nutrient cycling, biomass production, water regulation explore relationship effect EMF. Results Our results exhibited that decreased with increasing liana species richness, fungal complexity, which followed a trend initially then decreasing bacterial while complexity. Soil primarily affected cycling. Additionally, richness had significant negative on stocks. The random forest model suggested indicated more structural equation revealed tree displayed significantly positive effects EMF, via pathway. We also observed indirectly through bulk density thus influencing Simultaneously, we further found was main indicator rainforest, primary factor. Discussion findings provide new insight into between biodiversity contribution microibal function global climate change.
