Authors: Choudhary Prashant Kumar 
Published: June 2023

PurposeThe objective of the present work is to present the design optimization of composite cylindrical shell subjected to an axial compressive load and lateral pressure.Design/methodology/approachA novel optimization method is developed to predict the optimal fiber orientation in composite cylindrical shell. The optimization is carried out by coupling analytical and finite element (FE) results with a genetic algorithm (GA)-based optimization scheme developed in MATLAB. Linear eigenvalue were performed to evaluate the buckling behaviour of composite cylinders. In analytical part, besides the buckling analysis, Tsai-Wu failure criteria are employed to analyse the failure of the composite structure.FindingsThe optimal result obtained through this study is compared with traditionally used laminates with 0, 90, ±45 orientation. The results suggest that the application of this novel optimization algorithm leads to an increase of 94% in buckling strength.Originality/valueThe proposed optimal fiber orientation can provide a practical and efficient way for the designers to evaluate the buckling pressure of the composite shells in the design stage.

Mixotrophic microbes create carbon tipping points under warming
Authors: Wieczynski Daniel J. , Moeller Holly V. , Gibert Jean P. 
Published: June 2023

Abstract

Mixotrophs are ubiquitous and integral to microbial food webs, but their impacts on the dynamics and functioning of broader ecosystems are largely unresolved.

Here, we show that mixotrophy produces a unique type of food web module that exhibits unusual ecological dynamics, with surprising consequences for carbon flux under warming. We develop a generalizable model of a mixotrophic food web module that incorporates dynamic switching between phototrophy and phagotrophy to assess ecological dynamics and total system CO2 flux.

We find that warming switches mixotrophic systems between alternative stable carbon states—including a phototrophy‐dominant carbon sink state, a phagotrophy‐dominant carbon source state and cycling between these two. Moreover, warming always shifts this mixotrophic system from a carbon sink state to a carbon source state, but a coordinated increase in nutrients can erase early warning signals of this transition and expand hysteresis.

This suggests that mixotrophs can generate critical carbon tipping points under warming that will be more abrupt and less reversible when combined with increased nutrient levels, having widespread implications for ecosystem functioning in the face of rapid global change.

Grounding trait‐based root functional ecology
Authors: Fort Florian 
Published: June 2023

Abstract

A growing need exists to consider effects of biodiversity dynamics on the functioning of natural and anthropised ecosystems. This requires including the concepts of functional ecology, especially comparative trait‐based ecology, in a broad range of theoretical and applied studies. In parallel, the importance of the below‐ground compartment is increasingly recognised, which has exponentially increased the number of studies that consider root functional traits, despite limited understanding of their meaning. This perspective article (i) describes the origins of the trait‐based ecology framework, (ii) highlights current limitations of root‐system studies and (iii) recommends ways to address these limitations.

In recent years, studies claimed that above‐ground functional ecology had theoretical foundations without adequate empirical support. Root functional ecology has experienced the same problems and, for several reasons, its foundations seem even more unstable. Firstly, roots are difficult to collect, and it is difficult to precisely define components of the root system that have homogenous functions. Secondly, root systems are complex organs and have a diversity of functions, such as taking up nutrients and water, storing resources and anchoring plants. Thirdly, the theoretical background used in root functional ecology approaches is based on that of above‐ground ecology, specifically leaf functional ecology.

In the past several decades, root ecology benefitted from following the footsteps of above‐ground trait‐based functional ecology, which highlighted the existence of a variety of trait spectra that were partially related to species' ecology or their interaction with symbiotic microorganisms. However, root functional ecology is currently at a crossroads and must move beyond this above‐ground path and rediscover the origins of root ecology and include new traits based on root architecture and anatomy. Doing so requires developing innovative approaches that are more specific to the below‐ground compartment to improve understanding of plant roots and include them in large‐scale studies.

A novel approach for water reservoir mapping using controlled source audio‐frequency magnetotelluric in Xingning area, Hunan Province, China
Authors: Kouadio Kouao Laurent , Liu Rong , Malory Albert Okrah , Liu Wenxiang , Liu Chunming 
Published: June 2023

AbstractControlled source audio‐frequency magnetotelluric is frequently used in association with other geophysical methods, especially in complex geological areas to highlight geological structures such as water reservoir rock. Although it gives satisfactory results, combining several methods requires time and expense. In addition, despite this combination, several drilling locations proposed after geophysical investigations were inaccurate, resulting in many unsuccessful drillings. The latter occurs due to the difficulty to emphasize the fracture zones properly. To work around this problem, we proposed a novel approach called pseudostratigraphic to reduce the repercussion of unsuccessful drilled boreholes and to demarcate the water reservoir rock. The technique consists to discretize the resistivity of the inverted OCCAM2D model based on the true layer resistivities collected from the borehole log data (observed layers). The discrete resistivity model is known as the new resistivity model. It is used to generate the pseudostratigraphic log at each station by pseudo‐demarcating the thicknesses of the observed layers with a low margin of error. Moreover, the combination of multiple new resistivity models from different survey lines creates a three‐dimensional pseudostratigraphic map useful to emphasize the water reservoir rock. The pseudostratigraphic implementation is carried out in the Xingning area as a real‐world case study. The results show that the intersection of the main fault (F1) and the conductive zones (≤100 Ω m) indicates the potential water reservoir rock. Its thickness is estimated around 150–600 with an error equal to ± 7°m. Based on the three‐dimensional pseudostratigraphic map, the water found in the fracture zone located under the reservoir rock is considered much hotter due to the intense geothermal activity along F1, thereby making it a better place for hot water exploitation. Finally, the pseudostratigraphic technique could be an innovative and cheap strategy to find groundwater reservoirs in complex geological areas.
The interacting influences of competition, composition and diversity determine successional community change
Authors: Cadotte Marc William 
Published: June 2023

Abstract

Community change is one of the few constants in nature, and the balance of mechanisms influencing this change is central for understanding the structure and functioning of communities and ecosystems. Newly established communities undergo succession and can change in diversity and composition as local environmental change, interspecific interactions and immigration play out over time. Understanding the influence of initial conditions and priority effects (long‐term consequences of the initial community composition and species identity) on community change is critically important for both evaluating ecological theory and predicting restoration outcomes.

Here I evaluate how initial experimental conditions in 2012, like initial sown species richness, phylogenetic diversity and early biomass production, along with priority effects caused by the identity of sown species, influence subsequent herbaceous plant community composition and the number of colonizing species after 9 years of uninterrupted natural colonization.

I found that sown phylogenetic diversity (measured as mean pairwise distance) indirectly affected the number of colonizing species by increasing biomass production early on and plots with more biomass in 2012 were colonized by fewer species. Individual species influenced the number of colonizing species with taller species reducing the number of colonists and some shorter species subject to a greater number of colonists.

Synthesis. Taken together, these results indicate that initial composition influences the number of colonizing species via community‐wide competition. These findings suggest that restoration outcomes can be greatly influenced by decisions about sown species composition and early management practices.
Contrasted root trait responses between saplings of an arbuscular and an ectomycorrhizal tree species in open field compared to forest conditions

Published: June 2023

Abstract

Plant nutrient acquisition strategies range along a spectrum from autonomous foraging to investment in cooperative foraging through mycorrhizal associations. However, in temperate ecosystems, many plant species encounter contrasted levels of symbiont availability in open fields versus closed forests. Little is known about how fungal partner availability may be associated with intraspecific variation in other root foraging traits in natural settings.

Here, we addressed this issue by sampling saplings from two tree species: the arbuscular mycorrhizal (AM) Acer rubrum and the ectomycorrhizal (ECM) Quercus rubra from open fields (AM dominated) and adjacent forest plots (ECM dominated). For each species and environment, we measured morphological, architectural and symbiotic root traits.

For the open field, Quercus had greater specific root length (SRL) while Acer had higher AM colonization and root diameter. In the closed forest, the opposite pattern was observed, namely Quercus had higher ECM colonization and Acer greater SRL.

Both species showed evidence of a shift towards autonomous root foraging in the habitat with low expected symbiont abundance (open field for Quercus and forest for Acer). Although the confounding effects of site abiotic properties could not be strictly controlled in this study, these results suggest that plants might adjust root foraging traits according to local habitat conditions.

Synthesis: Our results shed new light on the intraspecific variation in plant position along the so‐called ‘collaboration gradient’, and suggest that mycorrhizal symbiont availability, along with other factors such as competition and site properties, may contribute to this variation.
Organizational Nostalgia: The Construct, the Scale and its Implications for Organizational Functioning
Authors: Leunissen Joost M. , van Dijke Marius , Wildschut Tim , Sedikides Constantine 
Published: June 2023

AbstractOrganizational nostalgia – a sentimental longing for past events in, and aspects of, one's organizational life – is a commonly experienced but poorly understood emotion. Qualitative research has explored how it helps employees cope with threat. Here, we examine its motivational properties. Building on the job demands–resources model, we hypothesized that organizational nostalgia – assessed with a newly developed and validated scale – predicts (in‐role and extra‐role) job performance, creativity and support for organizational change. Study 1 showcased the development of the Organizational Nostalgia Scale. We proceeded to hypothesize that work engagement, via need satisfaction, mediates the above‐mentioned positive relations, and tested these hypotheses in three additional studies. In Study 2, a multi‐source design with leader–follower dyads, leader organizational nostalgia was associated with increased leader organizational citizenship behaviour (OCB), as rated by followers. In Study 3, a lagged correlational design with employees, organizational nostalgia positively predicted OCB via work engagement. Finally, in Study 4, a lagged correlational design, organizational nostalgia predicted increased in‐role performance, creativity and support for organizational change. These associations were serially mediated by need satisfaction and work engagement. We conclude that organizational nostalgia has motivational implications. Our research affords a theoretical framework for the emotion and the means (i.e. a scale) to study it.
Metabolomic evidence of independent biotransformation pathways for terpenes in two specialist mammalian herbivores (genus Neotoma)
Authors: SCHRAMM Katharina , SKOPEC Michele , DEARING Denise 
Published: June 2023

AbstractHerbivory is common in mammals, yet our understanding of detoxification processes used by mammals to biotransform plant secondary compounds (PSCs) is limited. Specialist herbivores are thought to have evolved detoxification mechanisms that rely more heavily on energetically cheap Phase I biotransformation reactions to process high levels of PSCs in their diets. We explored this hypothesis by comparing the urinary metabolite patterns of two specialist herbivores (genus Neotoma). Neotoma stephensi is an obligate specialist on one‐seeded juniper (Juniperus monosperma). Neotoma lepida is a generalist forager across its range, yet populations in the Great Basin specialize on Utah juniper (J. osteosperma). While both juniper species have high levels of terpenes, the terpene profiles and quantities differ between the two. Individuals from both woodrat species were fed diets of each juniper in a cross‐over design. Urine, collected over a 24‐h period, was extracted and analyzed in an untargeted metabolomics approach using both GC‐MS and HPLC‐MS/MS. The obligate specialist N. stephensi excreted a unique pattern of Phase I metabolites when fed its native juniper, while N. lepida excreted a unique pattern of Phase II metabolites when fed its native juniper. Both woodrat species utilized the Phase II metabolic pathway of glucuronidation more heavily when consuming the more chemically diverse J. osteosperma, and N. stephensi utilized less glucuronidation than N. lepida when consuming J. monosperma. These results are consistent with the hypothesis that obligate specialists may have evolved unique and efficient biotransformation mechanisms for dealing with PSCs in their diet.
