Reproductive activities are often associated with conspicuous morphology or behaviour that could be exploited by predators. Individuals can therefore face a trade-off between reproduction and predation risk. Here we use simple models to explore population-dynamical consequences of such a trade-off for populations subject to a mate-finding Allee effect and an Allee effect due to predation. We present our results in the light of populations that belong to endangered species or pests and study their viability and resilience. We distinguish several qualitative scenarios characterized by the shape and strength of the trade-off and, in particular, identify conditions for which the populations survive or go extinct. Reproduction can be so costly that the population always goes extinct. In other cases, the population goes extinct only over a certain range of low, intermediate or high levels of reproductive activities. Moreover, we show that predator removal (e.g. in an attempt to save an endangered prey species) has the least effect on populations with low cost of reproduction in terms of predation and, conversely, predator addition (e.g. to eradicate a pest) is most effective for populations with high predation cost of reproduction. Our results indicate that a detailed knowledge of the trade-off can be crucial in applications: for some trade-off shapes, only intermediate levels of reproductive activities might guarantee population survival, while they can lead to extinction for others. We therefore suggest that the fate of populations subject to the two antagonistic Allee effects should be evaluated on a case-by-case basis. Although the literature offers no quantitative data on possible trade-off shapes in any taxa, indirect evidence suggests that the trade-off and both Allee effects can occur simultaneously, e.g. in the golden egg bug Phyllomorpha laciniata.

Environmental stressors alter multiple determinants of individual reproductive output in the acid-tolerant mayfly Leptophlebia vespertina

Jan Supina, Jindriska Bojkova, David S. Boukal

Summary: The study shows that indirect ecological feedbacks and food quality, rather than the direct effects of a stressful environment, may play a dominant role in influencing the reproductive output of acid-tolerant species like Leptophlebia vespertina in freshwater habitats.

From individuals to communities: Habitat complexity affects all levels of organization in aquatic environments

Pavel R. Soukup, Joacim Naslund, Johan Hojesjo, David S. Boukal

Summary: Habitat complexity influences aquatic ecosystems at multiple levels but there are research gaps and limitations hindering a full synthesis of its effects. High-resolution studies and consideration of ecological feedback are needed to better understand the role of habitat complexity in aquatic communities and ecosystems. Future research should focus on non-linear responses and incorporate multi-level experiments and monitoring to improve our knowledge in this area.

Delays, Masks, the Elderly, and Schools: First Covid-19 Wave in the Czech Republic

Ludek Berec, Jan Smycka, Rene Levinsky, Eva Hromadkova, Michal Soltes, Josef Slerka, Vit Tucek, Jan Trnka, Martin Smid, Milan Zajicek, Tomas Diviak, Roman Neruda, Petra Vidnerova

Summary: This study developed an age-structured epidemic model to analyze the first wave of Covid-19 in the Czech Republic. The findings suggest that implementing a lockdown four days earlier could prevent half of the confirmed cases by the end of the lockdown period. Personal protective measures, such as wearing face masks, are more effective than reducing social contacts. The strategy of only protecting the elderly is not effective, and keeping schools open is risky.

Effects of a microplastic mixture differ across trophic levels and taxa in a freshwater food web: In situ mesocosm experiment

Dilvin Yilcin, Gulce Yalcin, Boris Jovanovic, David S. Boukal, Lucie Vebrova, Derya Riha, Jelena Stankovic, Dimitrija Savic Zdrakovic, Melisa Metin, Yasmin Naz Akyurek, Deniz Balkanl, Nur Filiz, Djuradj Milosevic, Heidrun Feuchtmayr, Jessica A. Richardson, Meryem Beklioglu

Summary: The impacts of microplastics (MP) on freshwater lake ecosystems and food webs were examined. Results showed that the ingestion of MP by zooplankton was mainly limited to large-bodied Daphnia, leading to a decrease in biomass. Atrophic transfer of MP was observed through the presence of MP in the faecal pellets of odonate larvae. Despite the low impact on biomass transfer and emergence patterns, the experiment provided the first in situ observation of MP transfer to terrestrial ecosystems by emerging chironomids.

Invasive gibel carp (Carassius gibelio) outperforms threatened native crucian carp (Carassius carassius) in growth rate and effectiveness of resource use: Field and experimental evidence

Sandip Tapkir, David Boukal, Lukas Kalous, Daniel Barton, Allan T. Souza, Vojtech Kolar, Katerina Soukalova, Claire Duchet, Milan Gottwald, Marek Smejkal

Summary: Invasive alien species, such as the Carassius gibelio, pose a serious threat to the native biodiversity, particularly the native crucian carp (Carassius carassius) in European waters. This study identified resource competition as a possible ecological mechanism for the rapid decline of the crucian carp, with the invasive species demonstrating better food utilization and competitive abilities. The research combined field studies and controlled experiments to compare the growth patterns and food utilization between the two species, providing novel support for the hypothesis that the decline of the crucian carp is caused by the introduction and spread of the Carassius gibelio.

An evolutionary explanation of female-biased sexual size dimorphism in North Sea plaice, Pleuronectes platessa L.

Fabian M. Mollet, Katja Enberg, David S. Boukal, Adriaan D. Rijnsdorp, Ulf Dieckmann

Summary: Sexual size dimorphism is caused by differences in selection pressures and life-history trade-offs faced by males and females. Two mechanisms, namely male reproductive behavior and diminishing returns on male reproductive investments, can account for female-biased sexual size dimorphism in North Sea plaice. Observations suggest that higher investments in male reproductive behavior require increased energy acquisition, leading to a delay in maturation and contradicting male-biased sexual size dimorphism. However, diminishing returns on male reproductive investments alone can qualitatively explain the observed sexual size dimorphism, although the quantitative match is imperfect.

Body size and trophic position determine the outcomes of species invasions along temperature and productivity gradients

Samuel Dijoux, Noemie A. Pichon, Arnaud Sentis, David S. Boukal

Summary: This study investigates how species invasions affect the structure, diversity, and stability of simple communities, and predicts the factors influencing invasion success and consequences. The results suggest that warm and productive habitats are more susceptible to successful invasions, with smaller competitors, intraguild predators, and relatively small top predators being the most successful invaders. Additionally, successful invasions can either destabilize or stabilize community dynamics, depending on the environmental conditions and the trophic position of the invader.

A framework for relating natural movement to length and quality of life in human and non-human animals

Iain Hunter, Raz Leib

Summary: Natural movement is related to health, but it is difficult to measure. Existing methods cannot capture the full range of natural movement. Comparing movement across different species helps identify common biomechanical and computational principles. Developing a system to quantify movement in freely moving animals in natural environments and relating it to life quality is crucial. This study proposes a theoretical framework based on movement ability and validates it in Drosophila.

A geometric approach to the evolution of altruism

Andy Gardner

Summary: Fisher's geometric model is a useful tool for predicting key properties of Darwinian adaptation, and here it is applied to predict differences between the evolution of altruistic versus nonsocial phenotypes. The results suggest that the effect size maximizing probability of fixation is smaller in the context of altruism and larger in the context of nonsocial phenotypes, leading to lower overall probability of fixation for altruism and higher overall probability of fixation for nonsocial phenotypes.

A mathematical framework for the emergence of winners and losers in cell competition

Thomas F. Pak, Joe Pitt-Francis, Ruth E. Baker

Summary: Cell competition is a process where cells interact in multicellular organisms to determine a winner or loser status, with loser cells being eliminated through programmed cell death. The winner cells then populate the tissue. The outcome of cell competition is context-dependent, as the same cell type can win or lose depending on the competing cell type. This paper proposes a mathematical framework to study the emergence of winner or loser status, highlighting the role of active cell death and identifying the factors that drive cell competition in a cell-based modeling context.

Network-based uncertainty quantification for mathematical models in epidemiology

Beatrix Rahnsch, Leila Taghizadeh

Summary: This study forecasts the evolution of the COVID-19 pandemic in Germany using a network-based inference method and compares it with other approaches. The results show that the network-inference based approach outperforms other methods in short-to mid-term predictions, even with limited information about the new disease. Furthermore, predictions based on the estimation of the reproduction number in Germany can yield more reliable results with increasing data availability, but still cannot surpass the network-inference based algorithm.

Simulating tumor volume dynamics in response to radiotherapy: Implications of model selection

Nuverah Mohsin, Heiko Enderling, Renee Brady-Nicholls, Mohammad U. Zahid

Summary: Mathematical modeling is crucial in understanding radiobiology and designing treatment approaches in radiotherapy for cancer. This study compares three tumor volume dynamics models and analyzes the implications of model selection. A new metric, the point of maximum reduction of tumor volume (MRV), is introduced to quantify the impact of radiotherapy. The results emphasize the importance of caution in selecting models of response to radiotherapy due to the artifacts imposed by each model.
