“…Rainfall in the Atlantic Forest has been associated with historical rainfall originating from the Amazon rainforest through the phenomenon known as “Amazonian flying rivers” (Mercier, 2021; Salati et al., 1979; Salati & Vose, 1984; Zemp et al., 2014). Our teleconnection results (refer to Supporting Material) contribute to the existing body of literature by confirming that the state of São Paulo, particularly our specific field site, Serra do Japi, exhibits a dependency on water vapour transported from the Amazon during both the wet and dry seasons (Figures S3 and S4).…”

The onset of global climate change has led to abnormal rainfall patterns, disrupting associations between wildlife and their symbiotic microorganisms. We monitored a population of pumpkin toadlets and their skin bacteria in the Brazilian Atlantic Forest during a drought. Given the recognized ability of some amphibian skin bacteria to inhibit the widespread fungal pathogen Batrachochytrium dendrobatidis (Bd), we investigated links between skin microbiome health, susceptibility to Bd and host mortality during a die‐off event. We found that rainfall deficit was an indirect predictor of Bd loads through microbiome disruption, while its direct effect on Bd was weak. The microbiome was characterized by fewer putative Bd‐inhibitory bacteria following the drought, which points to a one‐month lagged effect of drought on the microbiome that may have increased toadlet susceptibility to Bd. Our study underscores the capacity of rainfall variability to disturb complex host–microbiome interactions and alter wildlife disease dynamics.

Exposure to Climatic Risks and Social Sustainability in Vietnam

This article constructed two spatial indices to better understand the interactions between social sustainability (an important but poorly defined concept) and exposure to climatic and environmental risks. The indices, and the Choropleth maps used to represent them, can be combined and operationalized across different country contexts to yield insights into how climate change and social vulnerabilities intersect and can be jointly addressed. The two indices were here applied to Vietnam, a country particularly exposed to climate change. While Vietnam is well-known for its vulnerability to changing temperatures and rising sea levels, there was huge variation within and between regions for these two risks. The analysis also found enormous spatial variation within the risks from precipitation, drought, deforestation, and air pollution. Social inclusion generally outperformed resilience and social cohesion, as well as empowerment in Vietnam. Our findings were robust for choices of indicators, weights, and aggregation specifications.

“…The first ruminations on the zonal concept can be seen in works of V. V. Dokuchaev (1883), whose idea was based on the principle of soil zonality (Mucina, 2019). Habitat zonality concerning vegetation has later been defined by H. Walter (Mercier, 2021). Even though the habitat zonality (sensu climate-dominant influence on the presence of vegetation in a habitat) is a general ecological approach to ecosystem classification (Bailey, 2002), it has become a fundament for landscape ecological classifications development (Hills, 1952;Krajina, 1965;Zlatník, 1976;Pfister & Arno, 1980;Pojar et al, 1987).…”

Zonal Concept: Landscape Level Parameters and Application

Zonal concept is a traditional approach in land assessment. Although its principles have been known for over a hundred years, they have not yet been thoroughly evaluated using modern analytical approaches. Assessing the empirically established parameters for characterising a zonal site, establishing threshold values of significant environmental factors, along with assessing the applicability of the zonal concept, were the goals of this study. The data analysed were obtained from the robust and objective Czech National Forest Inventory database. Regression, indirect ordination, hierarchical clustering and spatial analyses of geo-information systems were used. The study revealed seven crucial environmental factors: Slope, Slope Height, Terrain Surface Texture, Negative Openness, Multi-Resolution Index of Valley Bottom Flatness, Soil Type and Soil Subtype. A graphical model of zonal/azonal sites was constructed based on calculated threshold values of the factors. This methodic approach introduces significant geomorphological information that are otherwise problematically detectable in field mapping. We suggest it is possible to use the zonal concept as a base layer for general landscape assessment. Zonal site classification can become a part of a precise land management practice, consisting of valuable empiricism of traditional landscape ecological classifications enriched by modelling in disturbance ecology and prediction of climate change effects.
