Increasing Australian bush-fire frequencies over the last decade has indicated a major climatic change in coming future. Understanding such climatic change for Australian bush-fire is limited and there is an urgent need of scientific research, which is capable enough to contribute to Australian society. Frequency of bush-fire carries information on spatial, temporal and climatic aspects of bush...

Abstract Key message Extreme drought conditions, in addition to the urban heat island effect, modify growth response and water storage dynamics of Scots pine trees Stockholm region. Changes surface properties environments significantly impact local microclimate. While are known for providing important thermal regulation, climate on tree remains relatively unexplored. The present study focuses (...

The Indonesian island of Sulawesi harbors a highly endemic and diverse fauna sparking fascination since long before Wallace's contemplation of biogeographical patterns in the region. Allopatric diversification driven by geological or climatic processes has been identified as the main mechanism shaping present faunal distribution on the island. There is both consensus and conflict among range pa...

Paleoclimatic time series are often unevenly spaced in time, making it difficult to obtain an accurate estimate of their red-noise spectrum. A Fortran 90 program (REDFIT) is presented that overcomes this problem by fitting a first-order autoregressive (AR1) process, being characteristic for many climatic processes, directly to unevenly spaced time series. Hence, interpolation in the time domain...

Tree growth takes place at different time scales ranging from hours to days. To understand responses climate, continuous high-resolution measurements of tree diameter variations are needed, which usually obtained with automatic dendrometers. Here, we monitored stem increment Quercus faginea Lambert growing in central Portugal determine the effect climate on daily and seasonal dynamics during 20...

For the last two decades, climatically based interpretations have been the major focus in evolutionary studies of dryland alluvial fans. Climatic hypotheses to explain the development of alluvial fans in southern Death Valley, however, do not fare well when they are assessed with criteria used by philosophers of science. First and foremost, dating techniques do not have the chronometric precisi...
