“…Environmental conditions map directly to individuals’ physiological limits, whereas topographic complexity, habitat patch arrangement and geophysical feature configuration are associated with niche diversity. Physical barriers to movement and the persistence of landscape features can also affect biodiversity indirectly by enabling or restricting biotic interactions among species (Zarnetske et al, ) and affecting dispersal ability (Urban, Zarnetske, & Skelly, ). Components of geodiversity provide resources for species, including energy, water, nutrients and space (Parks & Mulligan, ).…”

Issue Geodiversity (i.e., the variation in Earth's abiotic processes and features) has strong effects on biodiversity patterns. However, major gaps remain in our understanding of how relationships between biodiversity and geodiversity vary over space and time. Biodiversity data are globally sparse and concentrated in particular regions. In contrast, many forms of geodiversity can be measured continuously across the globe with satellite remote sensing. Satellite remote sensing directly measures environmental variables with grain sizes as small as tens of metres and can therefore elucidate biodiversity–geodiversity relationships across scales. Evidence We show how one important geodiversity variable, elevation, relates to alpha, beta and gamma taxonomic diversity of trees across spatial scales. We use elevation from NASA's Shuttle Radar Topography Mission (SRTM) and c . 16,000 Forest Inventory and Analysis plots to quantify spatial scaling relationships between biodiversity and geodiversity with generalized linear models (for alpha and gamma diversity) and beta regression (for beta diversity) across five spatial grains ranging from 5 to 100 km. We illustrate different relationships depending on the form of diversity; beta and gamma diversity show the strongest relationship with variation in elevation. Conclusion With the onset of climate change, it is more important than ever to examine geodiversity for its potential to foster biodiversity. Widely available satellite remotely sensed geodiversity data offer an important and expanding suite of measurements for understanding and predicting changes in different forms of biodiversity across scales. Interdisciplinary research teams spanning biodiversity, geoscience and remote sensing are well poised to advance understanding of biodiversity–geodiversity relationships across scales and guide the conservation of nature.

“…Landscape structure and biotic interactions are inherently connected [14,15]. The landscape of the Wazihwei Nature Reserve, as illustrated in the present study, is similar to brocade in relation to the interplay of layers represented by the physical to polychaete and avian landscapes.…”

“…In the reserve, the mangrove vegetation patch, covering approximately 34% of the whole area, is the most conspicuous landscape other than the intertidal flat. As an ecosystem foundation and engineering species, the mangroves interact with driving forces, hydrodynamics, sedimentation and topography, thus changing the landscape of the mangrove-dominated ecosystem [2, 14, 71]. Mangrove overgrowth facilitates the homogenization of landscape structure and results in lowered macrofaunal species richness in wetland ecosystems from the bottom sediment to understory and canopy layers [2, 10, 13].…”

“…For example, as they act as both foundation species and ecosystem engineering species, mangroves can substantially change landscape structure through their biohydrological attributes. These changes could promote habitat availability for some species but not for others [14]. To properly manage mangrove-dominated wetlands, the data necessary for understanding the interactions among the geomorphological, hydrological, biological and socioeconomic domains that underlie mosaic landscapes are still missing for many of these wetlands, and a lack of relevant knowledge has caused many mangrove rehabilitation efforts to fail [1].…”

2 15 Abstract 16 Mangrove expansion monopolizes estuarine landscapes by diminishing habitat diversity and 17 hence biodiversity. Physical landcover types, including mangrove vegetation, influence polychaete 18 and avifauna habitat uses. The connections between the physical to biota-associated landscapes 19 warrant investigation. We determine how to best describe the landscape in a mangrove-vegetated 20 wetland according to the physical, polychaete and bird domains and identify what physical 21 attributes would affect the biota-associated landscapes. Differences among the physical and biota-22 associated landscapes were evaluated using multivariate ordination analyses. Six physical 23 landcover types were aligned along elevation, inundation and sedimentary gradients. The 24 polychaete-associated landscape was structured by three landcover types, mainly mangroves and 25 tidal flats with intermediate and high inundation. Deposit-feeding spionid and nereid, carnivorous 26 goniadid and suspension-feeding sabellid polychaetes depended on the different landcover types. 27 Shorebirds occurred distinctively in tidal flats with large, open surface areas. Egrets characterized 28 tidal flats and mangroves, and foliage and ground gleaners characterized mangroves. Open tidal 29 flats are crucial to polychaetes, which are the main prey of shorebirds and are also important to 30 egret foraging. Our results suggest that effective management strategies for conserving these 31 migratory birds require the maintenance of open tidal flats in the landscape. 32 33 Keywords: Landcover types; Physical setting; Biota-coupled landscape; Polychaete assemblage; 34 Bird assemblage 3 35 Introduction 36 Essential components of a healthy mangrove ecosystem include mud and sand flats, tidal 37 waterways, shallow water areas and circulating waters in addition to mangrove stands [1, 2]. These 38 mosaic and interconnected landcover types make mangrove ecosystems varied in terms of 39 landscape function and the production of both terrestrial and aquatic organisms [3-5]. Furthermore, 40 mangrove ecosystems are also among the most threatened ecosystems on Earth due primarily to 41 the devastating effects of anthropogenic activities [6, 7] and natural disturbance [8]. Assessments 42 of the relationships between the supplies provided by mangroves and demand from human society 43 have demonstrated intimate bottom-up and top-down connections between the functions of 44 mangrove ecosystems and the services they offer to human wellbeing [9]. When considering 45 mangrove trees alone, they compose a simple ecosystem with limited vegetation niches and low 46 bird species richness [10, 11]. At the landscape level, however, landscape heterogeneity within 47 both mangrove ecosystems and their surroundings is crucial in characterizing mangrove-dependent 48 bird assemblages [11-13]. Mangroves have been found to have both positive and negative roles in 49 ecosystems. For example, as they act as both foundation species and ecosystem engineering 50 species, mangroves ca...

“…For example, elephants dig, form trails, and trample (Haynes 2012), and vegetation and sediment interact to form streams and coastal dunes (Zarnetske et al 2012;Atkinson et al 2017). In turn, these species-modified features can feed back to mediate the strength and direction of biotic interactions among species and ultimately influence patterns of biodiversity (Zarnetske et al 2017). Even climate can be influenced by biodiversity and biogeographic patterns.…”

Biodiversity is essential for ecosystem functioning and ecosystem services (Chapin et al. 1997; Yachi and Loreau 1999). Yet rapid global change is altering biodiversity and endangering its vital functions, with human-caused habitat deterioration being the number one cause of biodiversity loss (Sala et al. 2000). In addition, climate change is directly affecting individual species abundances and distributions and indirectly affecting species via biotic interactions (Walther et al. 2002). When combined, these effects lead to novel ecological communities for which there are no modern analogs (Williams and Jackson 2007). Although species have continually experienced shifts in climate, the recent rate of temperature change is more rapid than in any other timeframe in the past 10,000 years (Marcott et al. 2013), and temperatures are expected to rise even faster in the near future (Smith et al. 2015). In light of these rapid global changes, a major challenge for biodiversity scientists is to generate robust statistical models that describe and predict biodiversity in space and
