Abstract Fire is a natural disturbance in many ecosystems worldwide, including tropical savannas, where it drives the assembly of animal and plant communities. The effect of fire is often indirect, impacting the availability of essential resources like food and shelter. The Brazilian Cerrado is the largest tropical savanna in the world, and ants comprise a very high proportion of its animal biomass. About one-third of the Cerrado ant fauna actively forages in the canopy. These ants use trees not...

Abstract Net primary productivity (NPP) is an important indicator of forest biomass accumulation as well as carbon sink capacity. Bamboo forests have gained much attention because of their high carbon sequestration potential. However, the estimations of bamboo forest NPP based on field investigations and statistical analyses in previous studies have varied and do not accurately reflect the spatiotemporal dynamics at the regional level, leading to missing information on the long-term spatiotempor...

Abstract Snout-vent length (SVL) and liver, gonad, fat bodies and carcass weight data from 661 individual Leptodactylus latrans frogs collected over ten years in the Pampa Region of Argentina were analyzed to evaluate the best approach for expressing the corresponding somatic indices. The seasonal variation of these indices and their respective correlation with body condition was also examined. Results obtained demonstrated that the weight of all examined tissues and organs vary in an allometric...

Abstract Soil organic carbon (SOC) has a vital role in the physical, chemical and biological behavior of the soil, and therefore prediction of the amount and mapping spatial distribution of SOC is necessary for sustainable soil management. However, the relationship between SOC and remotely sensed and easily accessible variables have been rarely reported. The main objective of the present study is, therefore, to estimate SOC using the remote sensing of satellite images as well as some field varia...

Abstract The coastal zone is one of the most valuable ecosystems worldwide because of the diverse and significant ecosystem services (ESs) it provides for human survival and development. Changes in land-use including coastal reclamation and erosion have altered the distribution of coastline and caused substantial changes in the structure and value of coastal ESs. In the past four decades, the mainland coastline in China has undergone extensive changes primarily due to coastal reclamation. This s...

Abstract The risks in agriculture due to climate change are highly specific because they largely depend on the agricultural system, latitude, topography, disposition, and other local conditions. As such, it is difficult to decide which mitigation and adaptation measures are the most suitable in a given country and which should be prioritized in planning and implementation. The objective of the paper is to present farmer and expert rankings of potential adaptation measures in Serbia’s agriculture...

Abstract Anthropogenic disturbances represent the main threat to biodiversity around the globe, yet effects are not restricted to species loss. Assessing the functional diversity, which measures the range and value of ecological traits of organisms, can provide a more direct link between biodiversity and ecosystem functioning. Therefore, as species’ responses to disturbances depend on their ecological traits, ecosystem functions are likely to be also imperiled by human perturbations. Although th...

Abstract Effective evidence-based nature conservation and habitat management relies on developing and refining our methodological toolbox for detecting critical ecological changes at an early stage. This requires not only optimizing the use and integration of evidence from available data, but also optimizing methods for dealing with imperfect knowledge and data deficiencies. For policy and management relevance, ecological data are often synthesized into indicators, which are assessed against ref...

Abstract Assessing status of natural resources and ecosystem components is pivotal for management, where indicators or indices often are used as proxies of ecological state. Many indicators, however, lack reference points and are associated with sampling errors and environmental noise, limiting their usefulness in management. Here we present a method for assessing state changes in ecological indicator from time-series: Analyses of Structural Changes in Ecological Time Series (ASCETS). ASCETS ena...
