Abstract Habitat complexity has been considered a key driver of biodiversity and other ecological phenomena for nearly century. However, there is still no consensus over the definition or how to measure it. Up‐to‐date clear guidance on measuring urgently needed, particularly given rise remote sensing advent technologies that allow environments be scanned at unprecedented spatial extents resolutions. Here we review measured in ecology. We provide framework metrics habitat complexity, related concept heterogeneity. focus two most commonly used ecology: fractal dimension rugosity. discuss pros cons these using practical examples from our own empirical data simulations. Fractal widely used, critical examination it drawing research scientific fields. also informational their potential benefits. chart path forward by presenting, as guide, sets essential desirable criteria metric should possess. Lastly, applied significance review.

The complexity of the habitat refers to its physical geometry, which includes abiotic and biotic elements. Habitat is important because it allows more species coexist and, consequently, interactions be established among them. links structure enclosure biological interactions, occur within limits. Enclosure should vary temporally, able influence animals in different ways, depending on period day season throughout year. In present paper, we discuss how important, can positively mental states zoo animals. We show ultimately affect educational projects. Finally, add enclosures thus, make lives interesting functional.

Ecological systems are quintessentially complex systems. Understanding and being able to predict phenomena typical of is, therefore, critical progress in ecology conservation amidst escalating global environmental change. However, myriad definitions complexity excessive reliance on conventional scientific approaches hamper conceptual advances synthesis. may be better understood by following the solid theoretical basis system science (CSS). We review features ecological described within CSS conduct bibliometric text mining analyses characterize articles that refer complexity. Our demonstrate study is a highly heterogeneous, endeavor only weakly related CSS. Current research trends typically organized around basic theory, scaling, macroecology. leverage our generalities identified suggest more coherent cohesive way forward ecology.

Abstract The fossil record is spatiotemporally heterogeneous: taxon occurrence data have patchy spatial distributions, and this patchiness varies through time. Large-scale quantitative paleobiology studies that fail to account for heterogeneous sampling coverage will generate uninformative inferences at best confidently draw wrong conclusions worst. Explicitly methods of standardization are necessary analyses large-scale datasets, because nonspatial sample standardization, such as diversity rarefaction, insufficient reduce the signal varying time or between environments clades. Spatial should control both geographic area dispersion (spread) localities. In addition standardizing distribution data, other factors may be standardized, including environmental heterogeneity number publications field collecting units report occurrences. Using a case study published global Paleobiology Database occurrences, we demonstrate strong signals sampling; without these signatures could misattributed biological processes. We discuss practical issues implementing via subsampling present new R package divvy improve accessibility analysis. software provides three approaches, well related tools quantify coverage. After reviewing theory, practice, history equalizing comparison groups, outline priority areas collection, analysis, reporting practices in paleobiology.

Abstract Forest structural complexity is a key element of ecosystem functioning, impacting light environments, nutrient cycling, biodiversity, and habitat quality. Addressing the need for comprehensive global assessment actual forest complexity, we derive near-global map 3D canopy using data from GEDI spaceborne lidar mission. These show that tropical forests harbor most high observations, while less than 20% temperate reached median levels complexity. Structural in more strongly related to attributes lower middle waveform layers, whereas upper layers are influential. Globally, exhibit robust scaling relationships between height, but these vary geographically by biome. Our results offer insights into spatial distribution emphasize importance considering biome-specific fine-scale variations ecological research management applications. The Waveform Complexity Index product, derived our analyses, provides researchers conservationists with single, easily interpretable metric combining various aspects structure.

ABSTRACT Aim Assessing how vegetation volume, fill, and complexity covary along elevation gradients is crucial for understanding the spatial distribution of animal diversity, a key question in biogeography ecology. Across ecosystems, canopy height sets limit to which, combined with should determine amount structures resources available populations; structural should, turn, promote niche differentiation. To facilitate future diversity studies, we address these variables each other across an gradient biodiversity hotspot where climate ecosystem productivity are well characterised. Location 3800 m on Eastern slopes tropical Andes. Time Period Present day. Major Taxa Studied Terrestrial plants. Methods We used land surveys digital photographs assess structure gradient, quantifying using information theory metrics. Results Whereas decreased elevation, density inside forest increased monotonically as increased, causing peak at mid‐elevations. The mid‐elevation was greatest when growing over trees, mainly epiphytes, considered. With few exceptions, measures interior, including plant life forms, vertical stratification, patterns stand microhabitat levels, peaked intermediate elevations coinciding patterns. Main Conclusions show that substrate its this region Andes, peaks cloud conditions. Given monotonic decrease temperature our data provide opportunity relative importance shaping mountain ecosystems.

Abstract Technological advances in three imaging techniques have opened the door to advanced morphological analyses and habitat mapping for biologists ecologists. At same time, challenge of translating complex 3D data into meaningful metrics that can be used conjunction with biological currently hinders progress accessibility. We introduce habtools , an R package provides functions efficiently calculate complexity shape from DEMs, meshes 2D shapes as well some helper facilitate workflow. expect functionality continue expand new faster methods become available, we welcome contributions ideas.

In urban community gardens, cultivated vegetation provides variable levels of habitat complexity, which can suppress pests by promoting predator diversity and improving pest control. this study, we examine three components the structural complexity garden (cover, diversity, connectivity) to investigate whether higher leads fewer herbivores, more predators, predation. We worked in eight gardens where quantified sampled arthropod community, measured predation on corn earworm eggs. found that plots with high cover supported species richness greater abundance predatory insects. High also a spiders. contrast, was negatively associated abundance. While positively egg predation, had negative impact suggesting antagonism between predators may limit biological Community gardeners thus manipulate promote their plots. However, composition prevalence interspecific ultimately determine subsequent impacts

Forests around the world, vital for ecological, economic, and social functions, are facing increasing threats such as deforestation habitat fragmentation. This study introduces “succolarity” to analyse forest connectivity fragmentation directionally in Romanian Carpathians from 2000 2021. Besides traditional indices fractal index (FFI), disorder (FFDI), local connected dimension (LCFD), succolarity, two novel proposed: potential succolarity delta (Δ) which provide nuanced insights into environmental changes human interventions forests worldwide. The tests showed invariance at image scale sensitivity obstacles different scenarios. combined analysis of reveals dynamic patterns connectivity, fragmentation, spatial disturbance. directional highlight enhance understanding patterns. FFI FFDI show levels across mountain groups, while LCFD details connectivity. adaptability method makes it globally applicable, supporting biodiversity conservation landscape management. In conclusion, integration provides a robust methodology comprehensive advancement not only supports sustainable management but also represents versatile approach applicable ecosystems worldwide, ensuring long-term resilience forested regions.
