Geodiversity in the Amazon drainage basin

Philosophical Transactions of the Royal Society A Mathematical Physical and Engineering Sciences, Год журнала: 2024, Номер 382(2269)

Опубликована: Фев. 12, 2024

The Amazon is the largest drainage basin on Earth and contains a wide variety of abiotic landscape features. In spite this, geodiversity in this has not yet been objectively evaluated. We address knowledge gap by combining meta-analysis an existing global map its components with systematic literature review, to identify key characteristics (ADB). also evaluate how these component maps, that are based geology, geomorphology, soils hydrology, could be refined better reflect basin. Our review shows geology—through lithological diversity geological structures—and hydrology—through hydrological processes influence geomorphology soil diversity—are main determinants geodiversity. Based features, ADB can subdivided into three principal regions: (i) Andean orogenic belt western Amazon, (ii) cratons eastern (iii) Solimões-Amazon river system. Additional methods geomorphological have identified. Future research should focus investigating relationship between assess their biodiversity. Such enhance conservation plans for ADB.

Towards a taxonomy of geodiversity

Philosophical Transactions of the Royal Society A Mathematical Physical and Engineering Sciences, Год журнала: 2024, Номер 382(2269)

Опубликована: Фев. 12, 2024

Geodiversity is a topical concept in earth and environmental sciences. information needed to conserve nature, use ecosystem services achieve sustainable development goals. Despite the increasing demand for geodiversity data, there exists no comprehensive system categorizing geodiversity. Here, we present hierarchically structured taxonomy that potentially applicable mapping quantifying across different regions, environments scales. In this taxonomy, main components of are geology, geomorphology, hydrology pedology. We propose six-level hierarchical where classified at progressively lower taxonomic levels based on their genesis, physical-chemical properties morphology. This can be used compile scientific research various applications value society nature conservation. Ultimately, first step towards developing global taxonomy. article part Theo Murphy meeting issue 'Geodiversity science society'.

Too much diversity—Multiple definitions of geodiversity hinder its potential in biodiversity research

Diversity and Distributions, Год журнала: 2024, Номер 30(6)

Опубликована: Апрель 5, 2024

Abstract Geodiversity—the diversity of abiotic features and processes the Earth's surface subsurface—is an increasingly used concept in ecological research. A growing body scientific literature has provided evidence positive links between geodiversity biodiversity. These studies highlight potential to improve our understanding biodiversity patterns complement current conservation practices strategies. However, definitions research vary widely. This can hinder progress geodiversity–biodiversity make it difficult synthesize findings across studies. We therefore call for greater awareness how is currently defined more consistent use term ‘geodiversity’

Quantitative measurement of geodiversity uniqueness: research implications and conservation applications

Philosophical Transactions of the Royal Society A Mathematical Physical and Engineering Sciences, Год журнала: 2024, Номер 382(2269)

Опубликована: Фев. 12, 2024

Quantitative approaches are needed to complement qualitative explorations identify sites with unique geodiversity and thereby guide geoconservation geoheritage programmes. Here, we introduce the concept associated index of 'geodiversity uniqueness'. This is based on a numerical analysis geofeatures allows identification in study area. We applied this approach geofeature data from three areas Finland. Our results showed that patterns uniqueness varied profoundly among across within each was due different sets distinct characteristics More importantly, presented here robust datasets selection criteria for sites, showing potential The promising starting point map can be further verified using field observations. To improve our knowledge variation, complementary providing objective information contributions total beta advance programmes spatial scales. article part Theo Murphy meeting issue 'Geodiversity science society'.

Geodiversity as a surrogate to inform freshwater fish diversity conservation and management

Journal of Applied Ecology, Год журнала: 2025, Номер unknown

Abstract Geodiversity offers novel insights into biodiversity patterns and their underlying mechanisms, thereby contributing to the development of conservation strategies amid widespread environmental changes human disturbances. However, relationship between geodiversity remains largely unexplored, particularly in freshwater ecosystems. Here, we investigated extent which accounts for fish diversity across dimensions (taxonomic, functional phylogenetic) levels (alpha beta) Lancang‐Mekong River. We first compiled three datasets (i.e. occurrence records, traits phylogenetic relations) seven geofeature group discharge, waterbody, topography, terrestrial cover, landform, soil rock) catchment. Multidimensional were then calculated at alpha beta levels, respectively. Next, assessed influence on multidimensional corresponding using generalized linear mixed models (GLMMs) structural equation modelings (SEMs). showed contrasting with showing positive upriver‐downriver gradients, but negative gradients along river continuum. The spatial congruence was weak geofeatures levels. substantially accounted variance both conditional R 2 GLMMs ranging from 0.892 0.996. increase primarily driven by growing variability discharge waterbody types, while mainly influenced rising dissimilarity types. SEMs revealed that indirect effects generally weak. Synthesis applications . Our findings emphasize profound large rivers, revealing its central role shaping through enhancing heterogeneity resource availability. To sustain diversity, it is crucial maintain types preserve linkages among components.

Geodiversity' defines the diversity of Earth's surface and subsurface, comprising features processes across geology (including soil), hydrology geomorphology (i.e.geodiversity elements).Geodiversity underpins systems that support living natural world: it is steadfast, resolute partnership humans biodiversity, providing what planet needs to life many materials we rely on in our daily lives.Its value also inherent, with geoheritage sites enjoyed world.Humans have always had a close cultural connection geodiversity its elements, important role was highlighted 1990s relation 'geoindicators' [1].Yet only recently importance considering has been more widely deeply discussed.This not least because emerging unsustainable human changes threaten globally.While climate biodiversity are now routinely included international conventions policy briefings (e.g. form 'essential variables'), abiotic variables other than largely overlooked.This risks biased or inadequate management decisions around subsurface resources, as well incomplete ecological analyses may impair conservation.To move these discussions forwards, applied for Royal Society Hooke Theo Murphy funding meeting experts several facets research.We were awarded 2019, hoping spring 2020 meeting, but all know happened then.Instead transferring online, decided wait until could

Despite the growing recognition of geodiversity in recent years, it remains overshadowed by its biotic counterpart, biodiversity. The objective this thesis is to narrow gap advancing quantitative assessment within context main provide a theoretical and methodological framework for study landscape-scale biodiversity investigations, with some insights nature conservation. To achieve goal, I will I) review theory geodiversity–biodiversity relationship, II) empirically test relationship Finnish freshwater ecosystems, III) data methods Europe-wide studies. By employing geographical research inspired ecological traditions, investigate between across aquatic terrestrial ecosystems. Empirical investigations revealed positive correlations vascular plant species richness distinct studies conducted Finland Switzerland, both This aligns assumption that fosters greater Moreover, produced provides ready-to-use variables future continent contributes large-scale general. In conclusion, recommend further development establishment systematic frameworks various contexts. Such actions would facilitate implementation standardized reproducible practices, thereby helping unlock geodiversity’s potential conservation practice. Integrating systematically into policy making essential fully acknowledge crucial role shaping sustainable future. broadening perspectives on natural diversity beyond alone, seeks enhance general understanding appreciation geodiversity.
