El sistema fluvio-marino del Río de la Plata (SFMRP) es un ambiente complejo, dinámico y altamente productivo dentro del cual las aves marinas tienen particular relevancia. Este sistema, de gran importancia ecológica, meteorológica y oceanográfica para la región, propicia el desarrollo de actividades humanas que traen aparejados problemas de conservación. En este trabajo caracterizamos los ensambles de aves marinas y su relación con las actividades que ocurren en el área desde una perspectiva ambiental. Dentro del ensamble de aves marinas (ca. 74 especies) del SFMRP, las gaviotas y gaviotines son los grupos más representativos y dominantes. El SFMRP también contiene una buena representación de Procellariiformes que utilizan principalmente aguas de altamar. Las principales actividades humanas desarrolladas en el área de interés, que incluyen el desarrollo urbano e industrial, las pesquerías comerciales y recreacionales, y la exploración-explotación de hidrocarburos, ocasionan fragmentación y degradación del paisaje, sobreexplotación de recursos, y contaminación (e.g., química, lumínica y sonora, entre otras). Las problemáticas ambientales destacadas afectan principalmente los movimientos, alimentación, y estado sanitario de las aves marinas que utilizan el SFMRP. Se identificaron y caracterizaron siete unidades de conservación a modo de enfoque para organizar y facilitar el desarrollo e implementación de herramientas de manejo. Destacamos la necesidad de reforzar la colaboración entre diferentes actores y sectores involucrados en el área para mitigar los impactos sobre la biodiversidad de aves marinas. Se recomienda además el establecimiento de programas de evaluación y/o monitoreo de los ensambles de aves marinas y desarrollar e implementar los planes de manejo de las unidades de conservación identificadas.

Effective management has a big effect on teachers' professional development and the establishment of mutual learning environments. The outcome of Principals' Instructional Leadership (PTL) on the growth of primary school teachers' professional learning communities was examined in this research, with a focus on the mediating function of school climate, particularly behaviors related to trust and knowledge sharing. 750 teachers from 85 primary schools, from a diversity of socioeconomic backgrounds throughout five districts, participated in the survey. The development of teachers' professional learning communities and principals' teaching leadership were found to be significantly correlated by the study using correlation analysis, mediation analysis, and structural equation modeling (SEM). Principals’ leadership in developing a learning-centered atmosphere directly affected teachers’ involvement and professional learning; this effect was entirely mediated by the degree of trust and information exchange in the school environment. According to these findings, principals can create a supportive school climate that promotes professional development by emphasizing teachers' collaborative knowledge sharing and trust building to strengthen professional learning communities.

Published: January 2025

Objective: Sucuk is a dry fermented meat product that naturally contains high numbers of lactic acid bacteria. This study investigated the feasibility of incorporating the probiotic lactic acid bacteria strain Lacticaseibacillus casei 431 in sucuk production.
Material and methods: For this purpose, three groups of sucuk were prepared: Group 1 with a starter culture (Latilactobacillus sakei S15 + Staphylococcus xylosus GM92), Group 2 with the probiotic culture (L. casei 431), and Group 3 combining both starter and probiotic cultures (L. sakei S15 + S. xylosus GM92 + L. casei 431). Then, the sucuk samples were subjected to physical, chemical, microbiological, and sensory analyses on the 0th, 30th, and 60th days of storage.
Results and conclusion: The results demonstrated that the microbial culture factor significantly influenced the sucuk samples’ pH, L* value, a* value, thiobarbituric acid reactive substances (TBARS), odor, taste, and overall acceptability scores, as well as the counts of lactic acid bacteria, Micrococcus/Staphylococcus, yeasts-molds, and L. casei (P < 0.01). However, it had no significant impact (P > 0.05) on water activity, b* value, color, or texture parameters. The storage period notably affected the TBARS, L* value and lactic acid bacteria (P < 0.05) and L. casei counts (P < 0.01), whereas it did not significantly alter other examined parameters (P > 0.05).

Authors: Tanggela Mardinanto , Arya Wijaya I Ketut Kasta , Suryani Luh Putu
Published: January 2025

Indonesia's constitution guarantees land ownership, yet disputes over land ownership remain widespread, particularly in regions like Southwest Sumba Regency, where competing claims to private property are frequent. This study addresses two key questions: 1) What are the root causes of land ownership disputes in Southwest Sumba Regency, and 2) What are the resolution patterns for these disputes? Employing normative research methods, this study aims to analyze both the causes and the resolution patterns of land ownership disputes in the region. Key causes include prolonged borrowing of cultivation packages, unclear land status without proper certification, land sales without family consent, boundary shifts without traditional leader involvement, and inequitable inheritance distribution. Resolution patterns in Southwest Sumba emphasize a family-centered approach, the active role of traditional leaders, and mediation facilitated by the Customary Peace Institute (LPA). Highlighting the urgency of addressing these disputes, this research suggests that raising public awareness about land ownership legality and bolstering governmental support for the LPA can enhance conflict resolution mechanisms. Moreover, the findings offer a model for other regions dealing with similar disputes and underline their relevance for policymaking to ensure equitable and sustainable land governance.

В статье предварительно проведен технический и элементный состав исходного сырья (угля и высоковязкой нефти), а также определены физико-химические показатели смолы сырья. Совместный пиролиз угля и высоковязкой нефти осуществляли при различных добавках нефти в интервале 5-30 %. Опыты проводили в алюминиевой реторте до 520 °С, в результате которых получены такие продукты, как смола, пиролизный газ и полукокс. При этом наибольший относительный прирост выходов смолы и пиролизного газа наблюдался при добавке высоковязкой нефти, составляющей 20 %, что по всей видимости связано с наблюдаемым синэнергетическим эффектом, основанном на взаимодействии угля и нефтяных фракций в процессе термической обработки.

Patient counseling is an integral part of pharmaceutical services at community pharmacies as community pharmacists are health care professionals most accessible to general public.  In this cross sectional qualitative study counseling quality of pharmacists and senior pharmacy technician was evaluated by using pseudo patient method. The study was conducted for 12 weeks at 35 community pharmacies randomly selected from various areas of Lahore. Four diseases which are most prevalent in developing countries were selected for this study. This study revealed that pharmacists were present at 52% of pharmacies visited. Counseling was offered hundred per cent on demand. On 6% pharmacies pharmacy technician refused to counsel on demand. Frequency, administration and storage of drugs were counseled frequently. Parameters like drug’s side effects, disease complications, drug interactions and contraindications were rarely addressed. Quality of counseling was much better in pharmacies where pharmacists were present, pharmacists counseled effectively about dose, frequency, administration, storage, side effects, drug interactions and complications. In order to improve quality of counseling at community pharmacies presence of pharmacist designated for patient counseling should be mandatory and continuing education programs should be run to update pharmacist and pharmacy technician knowledge.

Hydrophilicity of elastomeric impression materials is a key property in producing an accurate impression in prosthodontic treatment.
Aim: To study the hydrophilicity (wettability) of two different elastomeric impression materials in vitro by comparing the initial water contact angles on five materials during setting.
Materials and methods: Vinyl polysiloxane VPS (Imprint 4 Light and Super Quick Heavy) and Vinyl polyether silicone VPES (EXA’lence Light Regular, Light Fast and Heavy Fast set) were used. The leveled material surface received 1-µl droplet of deionized water 15 seconds after dispensing the impression material. Contact angles were measured at 0, 30, 60, 90, 120, and 150 seconds using a drop shape analysis machine. The data were analyzed using repeated measures ANOVA with time as a within-subjects factor and material as a between-subjects factor (α=0.05).
Results: All material had high contact angles at time 0 (T1). Imprint 4 had lower contact angles than EXA’lence at all times. There was a statistically significant difference in contact angles of all EXA’lence materials compared to Imprint 4 when not accounting for time (P .001). When time was factored in, there was no significant difference at T1 only (P = .08). There was no significant difference among the three EXA’lence materials (P > .990) at all-time points. However, there was a significant difference between Imprint 4 materials with Imprint 4 Super Quick Heavy having lower means than Imprint 4 Light (P = .001). This was true for all time points except T1.
Conclusions: Despite the high contact angle values at time 0 (T1), both materials reached a significant hydrophilic level with Imprint 4 having drastically lower mean values.
Keywords: Contact angle, elastomeric impression material, initial hydrophilicity, VPES, VPS.

Published: January 2025

Orthodontic treatment is elective but not without risks. Prospective patients need to be fully informed of their treatment options and understand the associated risks and benefits.
Aim of the study: To assess the perception of Nigerian orthodontic patients regarding the consent and assent-giving process before orthodontic treatment.
Material and Methods: A total of 349 patients from the University of Port Harcourt Teaching Hospital and Lagos University Teaching Hospital, who received orthodontic treatment between December 2023 and May 2024, participated in this study. A 21-item questionnaire was administered via Google Forms. The questionnaire contained demographic questions and items assessing knowledge, perception, and practice of consent in orthodontics. Data were analyzed using IBM SPSS Version 26, employing descriptive statistics (frequencies and percentages).
Results: Of the 349 participants, 99 (28.4%) were male, and 250 (71.6%) were female, with a mean age of 23.43 ± 10.49 years. 88% of female and 91.9% of male participants had heard of consent before treatment. A total of 93.1% of participants gave consent, with 78.5% of these being verbal. Pain (45.6%) was the most commonly explained complication, while infection (6.9%) was the least. 92% of participants were satisfied with the consent process.
Conclusion: Most Nigerian orthodontic patients are aware of the consent process and are generally satisfied with it. Orthodontists in Nigeria should prioritize obtaining written informed consent to ensure patient protection and avoid potential legal issues.

A doença arterial periférica (DAP) é caracterizada pelo estreitamento ou obstrução das artérias periféricas, resultante principalmente de processos ateroscleróticos. Nos últimos anos, a inflamação crônica tem sido identificada como um dos mecanismos centrais na patogênese da DAP. A modulação da resposta inflamatória, portanto, surge como um possível alvo terapêutico para o tratamento e prevenção da DAP. O presente artigo tem como objetivo geral analisar o papel da inflamação crônica na patogênese da doença arterial periférica e explorar novas abordagens terapêuticas que visam modular a resposta inflamatória. A pesquisa é fundamentada em uma revisão abrangente da literatura existente, para a coleta dos dados, foi utilizada a base de dados PubMed e Scielo, a pesquisa foi conduzida com os termos “Doença Arterial Periférica”, “Inflamação”, “Tratamento”, aplicando o operador booleano “AND”. A partir dos resultados apresentados, ficou claro que a inflamação crônica desempenha um papel central na patogênese da doença arterial periférica (DAP), influenciando diretamente a formação e a progressão das lesões ateroscleróticas, além de contribuir para a redução do fluxo sanguíneo nas artérias periféricas. A modulação da resposta inflamatória, seja por meio de intervenções farmacológicas ou mudanças no estilo de vida, mostrou-se uma estratégia promissora para o manejo da doença, com benefícios evidentes na redução dos marcadores inflamatórios, na melhoria do fluxo sanguíneo e na redução dos sintomas clínicos, como a claudicação intermitente. Em vista dos resultados obtidos, é possível concluir que a abordagem terapêutica combinada, que associa medicamentos anti-inflamatórios à reabilitação vascular e modificações no estilo de vida, pode representar uma alternativa mais eficaz no tratamento da DAP. Entretanto, são necessários mais estudos clínicos e ensaios randomizados para confirmar a eficácia dessas abordagens a longo prazo e explorar novas terapias que possam melhorar ainda mais o prognóstico dos pacientes. A pesquisa contínua sobre a relação entre inflamação crônica e DAP é fundamental para o desenvolvimento de tratamentos mais eficientes e personalizados para essa condição.

Published: January 2025

Perovskite photovoltaic compartments have garnered momentous consideration in photovoltaics owing to their easy manufacturing process and high efficiency. The optoelectronic properties of perovskite solar cells (PSCs), made from halide and diverse-halide materials, are exceptional. Perovskite structures exhibit remarkable stability despite a wide band gap and minimal charge transfer. Some advantages of perovskite solar cells are; high efficiency, low cost, rapid manufacturing, flexibility, energy payback time, sustainability, etc. To address these challenges, multidimensional perovskite materials are utilized to achieve long-term stability and good performance. Recent advancements in low-temperature synthesis methods and improved contact and electrode components have resulted in PSCs surpassing an efficiency of 25%. Perovskites' characteristics can also be enhanced by altering their elemental makeup. The light-harvesting perovskite material, the electron-transporting layer (ETL), the transparent conductive oxide (TCO) film, the hole-transporting layer (HTL), and the metal contact material. The most fantastic and popular perovskite material for sunny collecting at the moment is MAPbI3. Compared to the conventional MAPbI3 perovskite, additional perovskite substances, for example, assorted halide-assorted cation, hybrid cation, and hybrid halide, are drawing more interest. This paper mainly discussed metal-based PSCs, non-metal-based PSCs, and polymer-based PSCs. Moreover, there has been a significant focus on the constancy and production concerns that boundary the commercialization and modularization of perovskite solar cubicles.

Published: January 2025

During the first lineage segregation, mammalian embryos generate the inner cell mass (ICM) and trophectoderm (TE). ICM gives rise to the epiblast (EPI) that forms all cell types of the body, an ability referred to as pluripotency. The molecular mechanisms that induce pluripotency in embryos remain incompletely elucidated. Using knockout (KO) mouse models in conjunction with low-input ATAC-seq and RNA-seq, we found that Oct4 and Sox2 gradually come into play in the early ICM, coinciding with the initiation of Sox2 expression. Oct4 and Sox2 activate the pluripotency-related genes through the putative OCT-SOX enhancers in the early ICM. Furthermore, we observed a substantial reorganization of chromatin landscape and transcriptome from the morula to the early ICM stages, which was partially driven by Oct4 and Sox2, highlighting their pivotal role in promoting the developmental trajectory towards the ICM. Our study provides new insights into the establishment of the pluripotency network in mouse preimplantation embryos.
Predicting individual traits from models of brain dynamics accurately and reliably using the Fisher kernel
Authors: Ahrends Christine , Woolrich Mark W , Vidaurr Diego
Published: January 2025

Predicting an individual’s cognitive traits or clinical condition using brain signals is a central goal in modern neuroscience. This is commonly done using either structural aspects, such as structural connectivity or cortical thickness, or aggregated measures of brain activity that average over time. But these approaches are missing a central aspect of brain function: the unique ways in which an individual’s brain activity unfolds over time. One reason why these dynamic patterns are not usually considered is that they have to be described by complex, high-dimensional models; and it is unclear how best to use these models for prediction. We here propose an approach that describes dynamic functional connectivity and amplitude patterns using a Hidden Markov model (HMM) and combines it with the Fisher kernel, which can be used to predict individual traits. The Fisher kernel is constructed from the HMM in a mathematically principled manner, thereby preserving the structure of the underlying model. We show here, in fMRI data, that the HMM-Fisher kernel approach is accurate and reliable. We compare the Fisher kernel to other prediction methods, both time-varying and time-averaged functional connectivity-based models. Our approach leverages information about an individual’s time-varying amplitude and functional connectivity for prediction and has broad applications in cognitive neuroscience and personalised medicine.
Assessment of Glyphosate Roundup Turbo (450 g/l) on Haemato-biochemical Indices of Freshwater African Catfish (Clarias gariepinus) Fingerlings

Published: January 2025

The escalating use of glyphosate-based herbicides in agricultural practices has sparked concerns regarding their potential ecological impact. This study undertakes a comprehensive investigation into the acute ecotoxicological effects of a brand-new glyphosate (Roundup Turbo 450 g/l) on haematology and biochemical indices of Clarias gariepinus a commercially vital fish species in Nigeria. Fish were exposed to 0.0 as control, 0.5, 0.7, 0.9 and 1.2 mg/l glyphosate for 96 hours in the laboratory. Water quality parameters monitored were temperature, pH, dissolved oxygen electrical conductivity, nitrate and nitrite. The blood, liver and gills were extracted and analyzed. Haematological and biochemical analyses revealed significant changes (P < 0.05) as concentration increases. The decrease in red blood cell, pack cell volume, haemaglobin and white blood cell was indicative of glyphosate-induced hematotoxicity. Biochemical analyses disclosed alterations in enzymatic activities within liver and gill tissues, including significant increase in alanine aminotransaminases, aspartate aminotransferase and alkaline phosphatase, suggesting hepatic and branchial dysfunction and decrease in total protein, globulin and albumin, showing enhanced disruption in protein synthesis. Glucose and albumin in liver were not detected. Behavioral observations indicated the fish heightened stress response, characterized by erratic swimming patterns, increased agitation, equilibrium loss, hyperactivity and skin erosion. The 96-hour LC50 value for this study was 2.50 mg/l and it highlights glyphosate roundup turbo’s potential to exert detrimental effects on Clarias gariepinus populations. These findings underscore the imperative for sustainable agricultural practices, judicious pesticide management, and rigorous environmental monitoring to mitigate the ecological risks associated with glyphosate use.
Life history changes in the eastern collared lizard in response to varying demographic phases and management policies
Authors: Templeton Alan R. , Neuwald Jennifer L. , Conley Amy K.
Published: July 2023

By 1980 eastern collared lizards (Crotaphutus collaris collaris) had experienced massive local extinction on glades (open, rocky areas imbedded in a woodland matrix) in the Ozarks, a highland region in central North America. Lizards were translocated to the Peck Ranch Conservation Area in Missouri on three restored glades starting in 1984, and went through three demographic phases: (1) an isolate phase with initial growth followed by decline in population size and no colonization of nearby glades; (2) a colonizing phase of high dispersal and population growth that started with the onset of prescribed woodland burning, and (3) a stable metapopulation phase. We used mark/recapture information on over 1500 lizards with high sample coverage to estimate life history parameters. Life history was homogeneous within each phase, but differed significantly between phases. Changes occurred in less than a generation, indicating plasticity in life history. The isolate phase was characterized by low juvenile survivorship, high adult survivorship, long generation times, an old age structure, and almost no dispersal. The colonization phase had increased yearling survival, decreased adult survival, shorter generation times, a younger age structure, and much dispersal. The stable metapopulation phase was intermediate between these two extremes. These transitions indicated trade‐offs among different life history parameters. These plastic life history attributes show that species cannot be regarded as static units, resulting in not a life history, but rather a set of feasible life histories. Ignoring this set of feasible life histories can result in poor conservation decisions.

In this paper, two types of photo/thermal dual and programmable staged responsive shape memory PAEK are fabricated. On one side, photosensitive cinnamic acid (CA) is grafted onto shape memory poly(aryl ether ketone) (PAEK) chains to obtain PEAK‐CA with photo/thermal response. On the other hand, PAEK/CA composites are prepared via a facile physical blending as comparison. Both PAEK‐CA and PAEK/CA materials exhibit the excellent heat‐triggered (recovery ratio over 91.8%) and photo‐responsive shape memory effect (recovery ratio over 76.5%). More interestingly, the staged shape fixity and shape recovery behaviors can be realized by combining independent photo/heat responsive shape memory behaviors. Take the PAEK/CA for example, the irradiation with λ of 365 nm can be used for shape fixity, and shape recovery can be triggered by heating. Meanwhile, the fixation of the temporary shape of the sample can also be realized by heating–cooling process, and then the irradiation with λ of 365 nm is used for shape recovery. These photo/thermal dual and staged responsive shape memory PAEK materials could be widely utilized in fields of soft robots, smart actuators, and deformable devices.

Poly‐p‐phenylene‐(1,3,4‐oxadiazole) (POD) fibers have attracted tremendous attention due to the excellent thermal stability, however, their poor ultraviolet (UV) resistance seriously restricted the application. Some efforts have been devoted to improving the UV stability of POD, while the methods are generally too complicated or costly. This work applied a simple but effective approach to obtain POD/PPTA composite fibers by blending poly‐p‐phenylene terephthamide (PPTA) with POD. The results showed that the obtained POD/PPTA composite fibers exhibited enhanced tensile strength and heat resistance compared to the pure POD fibers. The POD/10%PPTA composite fibers retained 68% strength and 43% elongation even after 24 h UV accelerated aging. The improvement of UV resistance was attributed to the photoinduced electron transfer reaction in POD/PPTA composite fibers, which has been demonstrated by both experimental and simulation studies.

Microtiter plates are suitable for screening and process development of most microorganisms. They are currently the container of choice for high‐throughput and small‐scale microbial culture, but require optimization for specific work. In this research, a novel type of microtiter plate was developed using computational fluid dynamics (CFD) technology. The new plate provided high oxygen supply and optimal mixing effects for the fermentation culture of docosahexaenoic acid (DHA) producing strains, surpassing the conventional method of strain screening with shake flasks, which was insufficient. The shape of the microtiter plate was modified, and baffles were introduced to improve mass transfer and oxygen supply effects in the vibrating bioreactor. CFD technology was used to model the new plate's characteristics, establishing the superiority of hexagonal microtiter plates with six baffles. Parameters in the incubation process, such as vibration frequency and liquid load, were optimized, and the final result achieved an oxygen transfer coefficient (KLa) of 0.61 s−1 and a volume power input of 2364 w m−3, which was four to five times better than the original 96‐well plate. The culture results optimized by the model were also verified. Therefore, this new microtiter plate provides a powerful tool for future high‐throughput screening of strains.
Paid attention but needed support: Environmental awareness of Indonesian MSMEs during pandemic

This study aims to investigate the factors that instigate micro, small and medium enterprises (MSMEs) environmental awareness during the Covid‐19 pandemic from the attention based view perspective as the main theoretical lens. This topic is motivated by the increasing plastic use by MSMEs during the pandemic due to mobility restrictions. A survey was performed and generated in 485 usable responses which were then analyzed using PLS‐SEM to find the answers of whether the awareness of MSME owners or managers, business motivations, government regulations, social media and implementation constraints influence environmentally friendly practices by MSMEs during the pandemic. Consistent with the predictions based on the attention based view, the results show that all five factors contribute to the environmentally friendly practices by MSMEs during the pandemic. In addition, a support system from the government is needed to increase awareness and to turn it into actions, especially in the form of facilities, infrastructure and training to overcome the constraints in cost, time, and human resources capabilities. Research to investigate environmentally friendly activities carried out by MSMEs during a pandemic is still scant. This research is expected to fill this gap and provides practical as well as theoretical contributions in this area.

The fusion of tetrapyrroles with aromatic heterocycles constitutes a useful tool for manipulating their opto‐electronic properties. In this work, the synthesis of naphthodithiophene‐fused porphyrins was achieved through a Heck reaction‐based cascade of steps followed by the Scholl reaction. The naphthodithiophene‐fused porphyrins display a unique set of optical and electronic properties. Fusion of the naphtho[2,1‐b:3,4‐b’]dithiophene to porphyrin (F2VTP) leads to a ~20% increase in the fluorescence lifetime, which is accompanied, unexpectedly, by a more than two‐fold drop in the emission quantum yield (ϕ=0.018). In contrast, fusion of the isomeric naphtho[1,2‐b:4,3‐b’]dithiophene to porphyrin (F3VPT) results in a ~1.5‐fold increase in the fluorescence quantum yield (ϕ=0.13) with a concomitant ~30 % increase in the fluorescence lifetime. This behavior suggests that fusion of the porphyrin with the naphthodithiopheno‐system mainly affects the radiative rate constant in the Q‐state deactivation pathway, where the effects of the isomeric naphtho[2,1‐b:3,4‐b’]dithiophene‐ versus naphtho[1,2‐b:4,3‐b’]dithiophene‐fusion are essentially the opposite. Interestingly, nucleus‐independent chemical shifts analysis revealed a considerable difference between the aromaticities of these two isomeric systems. Our results demonstrate that subtle structural differences in the fused components of the porphyrin can be reflected in rather significant differences between the photophysical properties of the resulting systems.
Nano‐Strainer: A workflow for the identification of single‐copy nuclear loci for plant systematic studies, using target capture kits and Oxford Nanopore long reads

In modern plant systematics, target enrichment enables simultaneous analysis of hundreds of genes. However, when dealing with reticulate or polyploidization histories, few markers may suffice, but often are required to be single‐copy, a condition that is not necessarily met with commercial capture kits. Also, large genome sizes can render target capture ineffective, so that amplicon sequencing would be preferable; however, knowledge about suitable loci is often missing. Here, we present a comprehensive workflow for the identification of putative single‐copy nuclear markers in a genus of interest, by mining a small dataset from target capture using a few representative taxa. The proposed pipeline assesses sequence variability contained in the data from targeted loci and assigns reads to their respective genes, via a combined BLAST/clustering procedure. Cluster consensus sequences are then examined based on four pre‐defined criteria presumably indicative for absence of paralogy. This is done by calculating four specialized indices; loci are ranked according to their performance in these indices, and top‐scoring loci are considered putatively single‐ or low copy. The approach can be applied to any probe set. As it relies on long reads, the present contribution also provides template workflows for processing Nanopore‐based target capture data. Obtained markers are further tested and then entered into amplicon sequencing. For the detection of possibly remaining paralogy in these data, which might occur in groups with rampant paralogy, we also employ the long‐read assembly tool Canu. In diploid representatives of the young Compositae genus Leucanthemum, characterized by high levels of polyploidy, our approach resulted in successful amplification of 13 loci. Modifications to remove traces of paralogy were made in seven of these. A species tree from the markers correctly reproduced main relationships in the genus, however, at low resolution. The presented workflow has the potential to valuably support phylogenetic research, for example in polyploid plant groups.

Climate change is a global phenomenon, but natural selection occurs within landscapes. Many global analyses predict how climate change will shape behavior and physiology, but few incorporate information from the landscape scales at which animals actually respond to selective pressure. We compared cold‐water fish (redband trout Oncorhynchus mykiss newberrii) from neighboring habitats in a naturally warm, recently fragmented basin to understand how different responses to warming may arise from landscape constraints. Trout in warm, hydrologically connected Upper Klamath Lake fled summer temperatures and sought refuge in cool tributaries, while trout in an equally warm but fragmented reach of the Klamath River endured summer conditions. Trout in the river were more physiologically tolerant of high temperatures than trout in the lake across multiple metrics, including capacity for aerobic activity, recovery from exertion, and loss of equilibrium. Two independent metrics of energetic condition indicated that the behavioral strategy of trout in the lake came at a substantial energetic cost, while the physiological strategy of trout in the river was able to mitigate most energetic consequences of high temperatures. No clear genetic basis for increased tolerance was found in trout from the river, which may suggest tolerance was derived from plasticity, although our analysis could not rule out genetic adaptation. Our results show that landscape processes such as fragmentation can cause different climate survival strategies to emerge in neighboring populations. Connecting the mechanisms that favor similar survival strategies among related organisms at broad scales with mechanisms that drive landscape‐scale variability within taxa should be a major goal for future predictions of biological responses to climate change.
