Recent decades have seen substantial changes in patterns of biodiversity worldwide. Simultaneously, climate change is producing a widespread pattern of species’ range shifts to higher latitudes and higher elevations, potentially creating novel assemblages as species shift at different rates. However, the direct link…

When the species composition of ecological communities changes over time, environmental drivers are often invoked as the most plausible explanation. Several lines of reasoning, however, suggest that such compositional change, called temporal species turnover, can similarly result from intrinsic ecosystem dynamics, even…

Understanding the mechanisms behind biodiversity is central to assessing and forecasting anthropogenic impacts on ecological communities. However, quite how intrinsic ecological processes and external environmental drivers act together in natural systems to influence local temporal turnover is currently largely…

'Yongzhong Ye'] Species turnover is fundamental for understanding the mechanisms that influence large-scale species richness patterns. However, few studies have described and interpreted large-scale spatial variation in plant species turnover, and the causes of this variation remain elusive. In addition, the…

Range migrations in response to climate change, invasive species and the emergence of novel ecosystems highlight the importance of temporal turnover in community composition as a fundamental part of global change in the Anthropocene. Temporal turnover is usually quantified using a variety of metrics initially developed…

Turnover of species composition through time is frequently observed in nature. Often explained by changes in abiotic conditions or regional species pools, compositional turnover is employed as an indicator of external stress in natural ecosystems. Theoretically, the possibility of turnover driven by intrinsic…

Structure, composition and stability of ecological populations are shaped by the inter- and intraspecies interactions within these communities. It remains to be fully understood how the interplay of these interactions with other factors, such as immigration, control the structure, diversity and the long term stability…

'Jayanth R. Banavar' 'Amos Maritan'] The simplest theories often have much merit and many limitations, and in this vein, the value of Neutral Theory (NT) has been the subject of much debate over the past 15 years. NT was proposed at the turn of the century by Stephen Hubbell to explain pervasive patterns observed in…

The maintenance of diversity, the 'commonness of rarity', and compositional turnover are ubiquitous features of species-rich communities. Through a stylized model, we consider how these features reect the interplay between environmental stochasticity, intra- and interspecic competition, and dispersal. We show that…

Microbial community succession is a fundamental process that effects underlying functions of almost all ecosystems; yet the roles and fates of the most abundant colonizers are poorly understood. Does early abundance spur long term persistence? How do deterministic and stochastic processes influence the roles of founder…

Advances in metagenomic methods have revealed an astonishing number and diversity of microbial lifeforms, most of which are rare relative to the mostabundant, dominant taxa. The ecological and evolutionary mechanisms that generate and sustain broadly observed microbial diversity patterns remain debated. One possibility…

Taxonomic turnovers are common in the evolutionary histories of biological communities. Such turnovers are often associated with the emergence and diversification of groups that have achieved fundamental innovations beneficial in various ecological niches. In the present study, we show that such innovation-driven…

Biogeographical regions (geographically distinct assemblages of species and communities) constitute a cornerstone for ecology, biogeography, evolution and conservation biology. Species turnover measures are often used to quantify biodiversity patterns, but algorithms based on similarity and clustering are highly…

'Jordi Bascompte'] Many of the observed species interactions embedded in ecological communities are not permanent, but are characterized by temporal changes that are observed along with abiotic and biotic variations. While work has been done describing and quantifying these changes, little is known about their…

In many grasslands, species with specific traits occupy unique temporal positions within communities. Such intra-annual segregation is predicted to be greatest in systems with high variability (i.e., seasonality) in precipitation and temperature because fluctuating environmental conditions select for species that…

Despite widespread recognition of the dynamic nature of ecological interactions, the consequences for community persistence of the observed year-to-year changes in species interactions have remained overlooked. Our research bridges this gap, leveraging a uniquely high-quality dataset spanning 8 years and 12 independent…

While studies increasingly document long-term change in community composition, whether long-term change occurs gradually or via rapid reorganization events remains unclear. We used Latent Dirichlet Allocation (LDA) and a change-point model to examine the long-term dynamics of a desert rodent community undergoing…

Disturbance caused by large herbivores can affect the relative importance of ecological processes in determining community assembly and may cause a systematic loss of biodiversity across scales. To examine changes in the community assembly pattern caused by an overabundance of large herbivores in Japan, we analyzed…

'Jesús Castillo-Cerón' 'Norma Manriquez' 'Aurelio Ramírez-Bautista' 'Alberto E. Rojas-Martínez' 'Gerardo Sánchez-Rojas' 'Iriana Zuria' 'Claudia E. Moreno' 'Hubert Vaudry'] Quantifying differences in species composition among communities provides important information related to the distribution, conservation and…

The human physiological system consists of several biological units carefully organized to engage in a bio-physicochemical interaction with complex fluids transporting nutritional and life-supporting species (oxygen and carbon dioxide) needed for the proper functioning of the body. The nutritional species are products…

Acceleration of catalytic transformation of molecules via heterogeneous materials occurs through design of active binding sites to optimally balance the requirements of all steps in a catalytic cycle. In accordance with the Sabatier principle, the characteristics of a single binding site are balanced between at least…

There were conflicting definitions and misrepresentations of turnover frequency (TOF), catalytic cycle frequency (CCF), and catalytic first-order rate constant (kcat) in the literature. Based on the Benfield and Lineweaver-Burk methods, data were generated. The results showed that the CCF for the forward (3.63 exp.…

Extreme weather events increasingly threaten coastal water quality, yet the mechanisms by which tropical cyclones impair microbial conditions remain poorly quantified. We develop a Large Language Model–Assisted Microbial Source Tracking (LAMST) framework to trace the origins of microbial threats—fecal indicator…
