A pluralistic, socio-ecological approach to understand the long-term impact of mountain conservation: a counterfactual and place-based assessment of social, ecological and hydrological change in the Groot Winterhoek Mountains of the Cape Floristic Region
… and ecological drivers of landscape change? Aim and objectives: I use a pluralistic, socio-ecological framing to assess the impact of ~40 years of mountain protection, drawing on comparisons of ~30 and ~40 years before and after protection respectively, with an adjacent area of …

Palaeoenvironmental and palaeogeographic reconstruction of the Tequixquiac Basin, Central Eastern Mexico: Mid to late Pleistocene environments
… for mid to late Quaternary environmental change in the Tequixquiac region of Central-eastern Mexico. This project has logged over 50 stratigraphic sections and geochemically analysed a 55 m lithostratigraphic sequence for multi-proxy palaeoenvironmental information. The main research …

Unravelling abiotic and biotic drivers of biodiversity change in local plant and invertebrate communities after 80 years - a re-visitation study on the Studland peninsula.
… communities respond to long-term environmental change via changes in species richness and composition is an urgent question in the 21st century as anthropogenic forces drive biodiversity declines across taxa and regions. As environmental conditions change over time, effects may cascade through …

Deep-lake carbonates and speleothems as high-resolution archives of paleohydrology in the Bonneville Basin, UT
… to have been highly sensitive to hydroclimate changes during the past glacial period; closed-basin lakes in this region have been studied for over a century. We present lake and speleothem records from the Bonneville Basin that are anchored by high-precision U-Th ages. Deep-lake carbonates are …

Robustness and precision of Holocene palaeoclimatic records from peatlands using testate amoebae
… (Protozoa: Rhizopoda) analysis to measure hydrological fluctuations in British peatbogs over the Holocene. Changes in the fossil species assemblage are used to reconstruct the mean annual water table records at different locations on mire surfaces using a transfer function designed for …

Ecological interactions of natural processes and new urban form : a landscape ecological analysis fo the change of urban and natural patterns in eastern-Taipei metropolitan fringes
… between city form, forest patch shape and hydrological effects in the case study of eastern Taipei. Some landscape ecological indices like forest patch numbers, corridor connectivity, compactness of city form, landscape fragmentation and landscape heterogeneity are measured across different …

Evaluating Future Runoff, Water Stress and Fluvial Flooding in China under Climate Change
China faces complex changes in runoff variability, water stress, and fluvial flood hazards under climate change and socioeconomic development. Understanding how these processes may evolve under future scenarios is critical for long-term water resource planning and climate adaptation. However, …

A pollen analytical investigation of Holocene palaeoenvironments at Lake Tyrrell, semi-arid Northwestern Victoria, Australia
… sediments of Lake Tyrrell record a history of hydrological change extending to approximately 10,000 BP. Between 10,000 BP and 6600 BP water in Lake Tyrrell was shallow, saline and probably ephemeral. Water depths and the frequency I duration of flooding were most likely similar to those …

Holocene vegetation history and environmental change in the forest-grassland mosaic of the Central Highlands of Madagascar
… the vegetation history and environmental change in the Central Highlands of Madagascar during the Holocene using palaeoecological methods, in order to inform appropriate conservation and management plans. We provide new records of vegetation, hydrological change, fire and herbivory …
