Summary: Species distributions and dynamics are influenced by the interplay between dispersal at different spatial scales and landscape connectivity and composition. This study examines the effects of these factors on local species dynamics using a host-parasitoid model. The results demonstrate the importance of both local and regional scales, as well as the combined effects of species biological parameters and landscape structure, in shaping species density and occupancy. These findings have practical implications for the development of effective strategies for biological control.

Summary: A novel predator-prey system combining prey refuge with fuzzy parameters is formulated in this manuscript. Sufficient conditions for the existence and stability of biological equilibria are derived, and the existence of bionomic equilibria is discussed under fuzzy biological parameters. The optimal harvesting policy under imprecise inflation and discount in fuzzy environment is investigated using Pontryagin's maximal principle, with meticulous numerical simulations performed to validate the theoretical analysis.

Summary: This study investigates the triple effects of imprecision of biological parameters, prey refuge behavior, and fishing activities on the dynamics of the system. A novel fishery model is proposed, incorporating variable prey refuge and imprecise parameters. The dynamic properties of the model are analyzed, and the effects of different factors on equilibrium existence and stability are discussed. Additionally, the introduction of the weighted fishing strategy promotes sustainable development of fishery resources. Numerical verifications are conducted to demonstrate the impact of these factors on the system's behavior.

Summary: The paper investigates the threshold behavior of a stochastic predator-prey system with various factors, and finds ways to improve the survival rates of prey and predator. Prey survival rate can be enhanced by strengthening refuge, reducing fear cost or decreasing white noise intensity, while predator survival rate can be increased by weakening refuge strength, increasing fear cost or reducing white noise intensity.

Summary: This study investigates the impact of fear on prey populations and prey refuges in a predator-harvested Leslie-Gower model. The research focuses on analyzing the number and stability properties of all positive equilibria and uses numerical simulation to evaluate the stability. Additionally, sensitivity investigations are performed on model solutions in relation to fear impact, prey refuges, and harvesting.

Summary: The study found that an invasive predatory snail failed to drive a native, threatened non-predatory snail to extinction due to different tolerance ranges for exposure to sunlight. The researchers developed a novel miniature light sensor, small enough to be carried by these snails on their shells, to test this hypothesis.

Summary: This paper investigates the existence of multiple periodic solutions in a delayed prey-predator model with a refuge and a non-monotone functional response. By employing Mawhin's coincidence degree and nontrivial estimation techniques, the authors prove the existence of multiple periodic solutions and provide an example to demonstrate the feasibility of their main results.

Summary: The littoral zone of shallow water bodies plays an important role in predator-prey interactions, with sediment serving as a refuge for planktonic microcrustaceans. The study showed that the assemblage and size structure of crustaceans and fish, as well as biotic interactions, vary along the heterogeneity gradient of the littoral zone. This research contributes to understanding the defense strategies developed by zooplankton against predators.

Summary: This article discusses why some spaces of refuge are excluded from global maps of forced migration, highlighting the partiality of current refuge geography based on Western legal norms. It argues that focusing on alternative refuge locations and forms is crucial for understanding forced migration accurately and challenging dominant moral geographies of asylum and responsibility-sharing.

Summary: This research article focuses on a new prey-predator model that takes into account the effects of predation fear, prey refuge, and carry-over effects. The model is analyzed using fractional differential equations (FDEs) and incorporates concepts such as anti-predator behaviors and memory effects. The study investigates the well-posedness, stability, and Hopf bifurcation of the model and provides valuable insights into the dynamics and complexities of prey-predator interactions.

Summary: This paper aims to study the impact of anti-predator behavior caused by fear and prey shelters on a prey predator system. The study finds that an increase in fear level can improve system stability and decrease the population of predator species without causing their extinction. Prey shelters also play a vital role in the persistence of predator populations.

Summary: The ladybird beetle Cryptolaemus montrouzieri has a high-quality genome sequence showing expansions and contractions in certain gene families compared to other beetles. Differences in gene expression on unnatural diets suggest that nutritional deficiencies may explain lower performance. An expansion in immune effector genes in the genome may also play a role in diet adaptation.

Summary: In this paper, a new discrete method is used to deduce a predator-prey model with discrete time in the interior of R-+(2) and study its local dynamics and Neimark-Sacker bifurcation. Discrete models, compared with continuous ones, have unique properties that provide a new perspective for understanding the changing patterns of biological populations. The existence and stability of equilibria are analyzed, and the formation conditions of Neimark-Sacker bifurcation are established. An attracting closed invariant curve appears, corresponding to periodic oscillations between predators and prey over a long period of time. Numerical simulations and their biological meanings are given to reveal complex dynamical behavior.

Summary: Semiochemicals are signaling chemicals produced by one organism that elicit behavioral responses in another organism. While widely used in monitoring and controlling insect pests in agriculture and forestry, they are not commonly utilized in weed biological control. Semiochemicals can be used for monitoring, aggregation, and repelling of biocontrol agents, and have the potential to enhance weed biocontrol programs significantly. Collaboration and research on semiochemicals and chemical ecology could lead to more successful implementation in weed biocontrol.

Summary: The model developed captures the dynamics between predators and prey, with a control term used to limit prey growth. The results ensure the existence of optimal pest control strategies, as demonstrated through numerical integrations, with a specific example provided for context.

Summary: Money spiders play an important role in conservation biological control in cereal crops, and their prey choice dynamics can help maintain a consistent dietary intake. They tend to consume each other more than expected, showing a propensity towards intraguild predation, while also consuming common pest families.

Summary: The study introduces a protocol called Macroutrient Extraction and Determination from Invertebrates (MEDI) for the direct, rapid, and relatively low-cost determination of macronutrient content from single small macroinvertebrates. Macronutrients are extracted and determined using colorimetric assays, successfully identifying taxonomic differences in macronutrient content. MEDI can determine macronutrient content in small and large individual invertebrates, with the total cost of around $1.35 per sample and results obtained within around 3 days.

Summary: Yellow sticky traps effectively sampled winged cereal aphids and identified spatial differences in immigration patterns within- and between fields. Farmers and agronomists need to improve their aphid identification skills, although they could detect aphid trends with minimal training. At least three times more cereal aphids were captured in crop headlands, especially next to taller field boundaries indicating that wind currents determined aphid immigration patterns within fields.

Summary: This study investigated the genetic control of polyphenol accumulation in red raspberry through measuring the levels of total anthocyanins and 37 individual polyphenol metabolites. Quantitative trait loci (QTLs) for these traits were identified, with different QTLs affecting the accumulation of different polyphenols. This provides great potential for marker-assisted breeding for improved levels of potentially health beneficial components.
