Ecological boundaries between different environments are important for generating and maintaining biodiversity and for understanding community assembly. Classic examples include temperature gradients between upland and lowland habitats and estuaries (brackish) between fresh- and saltwater. While numerous studies have…

Tropical forests are incredibly diverse in structure and function. Despite, or perhaps because of, this diversity, tropical biologists often conduct research exclusively in one or perhaps a few forest types. Rarely do we study the ecotone-the interstitial region between forest types. Ecotones are hyper-diverse, dynamic…

Here we present extinction, extirpation and coexistence conditions where / when two communities combine. We consider one specific model where two communities coalesce, and another model where the communities coexist side by side, blending in a transitionary zone called the ecotone. Specifically, (1) we analytically…

Understanding the relationships between soil macrofauna and decomposition is crucial for predicting how land-use change impacts ecosystem function in fragmented systems. This is because soil macrofauna affect decomposition and also respond to the changes in abiotic conditions across habitat gradients. This study…

'Md. Khorshed Alam' 'Junjiro Negishi'] Title: ABSTRACT Seasonal changes in the environment often strongly influence biological communities. In environmental transition zones, or ecotones, the environment fluctuates over time between two different types of environments and the seasonal change is more pronounced.…

Scarce studies on microbial diversity in tropical caves have been published, a subterranean system still neglected from a microbiological point of view. Although most published studies are about temperate caves, usually archaeas and fungi have less attention than bacterial communities. Here, the microbiome structure…

'Ping Zou' 'Xiaoyi Bi' 'Shuibing Li' 'Richard Lizotte'] Freshwater lake eutrophication is a global concern causing adverse effects on aquatic ecosystems. The degradation of lake aquatic-terrestrial ecotones, which are the transitional zones between terrestrial and water ecosystems, contributes to eutrophication. These…

'Jane Uhd Jepsen'] Several generic methods have recently been developed for change detection in heterogeneous remote sensing data, such as images from synthetic aperture radar (SAR) and multispectral radiometers. However, these are not well suited to detect weak signatures of certain disturbances of ecological systems.…

Habitat suitability commonly differs between the core and periphery of ecosystems. The longleaf pine ecosystem is recognized for its value in providing habitat to a variety of specialist and endemic species, especially herpetofauna. However, at the northernmost extent of longleaf pine (in southeastern Virginia) little…

Grain Amaranth, Amaranthus hypochondriacus L., is an emerging arable crop cultivated worldwide. One way to obtain resources from the crop, other than grain, is to grow Amaranths in the dry season and harvest only the leaves. In this environmental condition the response of an Amaranth agroecosystem to the presence of…

Title: Summary Blue carbon ecotones (BCEs) play a critical role in regulating abiotic and biotic ecological fluxes underpinning services which are also crucial for the protection of the land-ocean function. Here, we proposed a Benefit-Pressure-Transformation Risk model (BPT) to calculate the Ecosystem Health Index…

The study of elevational diversity gradients is a central topic in biodiversity research. In this study, we tested for the effect of climate, resource quality and habitat heterogeneity on earthworm communities along an altitudinal gradient and around the treeline in the French Alps. Earthworm communities and…

'Emilia Gutiérrez' 'Maaike Y. Bader'] Title: ABSTRACT Alpine treeline ecotones, when viewed up close, display considerable variation in spatial patterns, which have been associated with different responses to climate change. Two important dimensions of treeline-ecotone spatial patterns are the abruptness of the change…

Widely distributed plants of western North America experience divergent selection across environmental gradients, have complex histories shaped by biogeographic barriers and distributional shifts, and often illustrate continuums of reproductive isolation. Rubber rabbitbrush (Ericameria nauseosa) is a foundational shrub…

'John A. Endler'] Abstract. We present an AI-based ecosystem simulator that uses threedimensional models of the terrain and animal models controlled by deep reinforcement learning. The simulations take place in a game engine environment, which enables continuous visual observation of the ecosystem model. The terrain…
