Summary: Diseases and parasitic organisms can impact ecosystems by altering host behavior and ecological interactions. In this study, it was found that fish infected with parasites varied in their behavior, with different infection levels affecting territory sharing and proximity to food patches. Moreover, the effects of parasites on the host were context-dependent and influenced by individual variability.

Summary: Parasites can affect the visual system of fish, even without causing obvious pathology. When exposed to flashes of light, the intensity of the parasite is positively correlated with c-Fos gene expression, potentially causing difficulties for fish in distinguishing external environmental features.

Summary: Two species of forest-dwelling salamanders in Italy, Salamandrina perspicillata and Speleomantes strinatii, exhibit interference competition rather than exploitative competition. The foraging activity of the smaller species, S. perspicillata, is negatively affected by the presence of the larger species. This competitive interaction is size mediated.

Summary: Eye flukes are common in freshwater lakes, with high infection pressures potentially causing mortalities in fish populations. Dominant genera include Tylodelphys and Diplostomum, with exposure to high numbers of cercariae leading to lethal effects on fish hosts. Sublethal doses result in significant regulation of immune genes in fish, with some cytokine genes showing upregulation at early infection stages.

Summary: Research shows that pelagic seabirds breeding on tropical islands can deplete their primary prey species over a considerable area, a phenomenon known as "Ashmole's halo". The study results suggest that the gradient of prey depletion by seabirds is mirrored by an opposing trend in their foraging effort, which is not influenced by environmental factors and can be approximated by a model.

Summary: The composition of plant-pollinator interactions is dynamic, and our understanding of how these interactions change in nature is limited. Research indicates that in drought years, plants' floral visitation niches expand while the composition of flower visitors does not show statistically distinguishable changes.

Summary: Fasciola hepatica, commonly known as liver flukes, is a significant parasitic disease affecting humans and livestock worldwide. Drug resistance has become a global issue, necessitating the implementation of an integrated parasite management program. A rapid DNA test using loop-mediated isothermal amplification was developed for the detection of F. hepatica from faecal and water samples, enabling real-time decision making to control parasite prevalence.

Summary: This study investigated the combined effects of temperature and predator infection status on the consumer functional response of three-spined sticklebacks towards free-living cercariae stages of common freshwater trematode parasites. Results showed genus-specific functional responses and consumption rates towards each parasite prey, with an overall higher consumption rate on T. franki. Elevated temperature increased consumption rate on one parasite prey, while sticklebacks with mild cestode infections exhibited higher consumption rates for that particular parasite prey.

Summary: We analyzed the modular structure of host-parasite networks and found that different forms of parasitism respond differently to environmental factors, with host individual traits playing a key role in network configuration.

Summary: The study suggests that individuals with higher metabolic rates may be more social, but not necessarily prefer larger groups; however, the impact on group size choice is weak. Furthermore, variations in food availability and predation risk could further alter the effects of metabolism on group size choice.

Summary: Animals precisely control the morphology and assembly of guanine crystals to produce diverse optical phenomena, but little is known about the regulation of crystallization to produce optically useful morphologies. This study demonstrates that pre-assembled, fibrillar sheets in developing scallop eyes serve as templates for nucleation and direct the growth and orientation of plate-like guanine crystals, resembling melanosome morphogenesis. The similarities in the control mechanisms of melanin and guanine formation inspire new approaches for manipulating molecular material properties and morphologies.

Summary: The study reveals four hypotheses about strategic interactions between individuals and tests them using body mass data of co-existing fishes, showing experimental support for the predictions. The findings suggest quantifiable mechanisms governing animal behavior strategies in populations or communities.

Summary: Parasites with complex life cycles can induce phenotypic changes in intermediate hosts to increase transmission to the final host. The consequences of parasite load on transcriptional activity and morphology of the cestode Anomotaenia brevis and its intermediate host, the ant Temnothorax nylanderi, were investigated. The study revealed that heavily infected hosts showed a stronger immune response and fight against oxidative stress, while the cestodes became smaller when competing with other parasites for resources from a single host, indicating shifts in host immune avoidance, starvation resistance, and vesicle-mediated transport.

Summary: The invasive species W. auropunctata has shown competitive advantages over resident ants in southern China, especially in terms of food and space resources, potentially leading to the replacement of some native ant species.

Summary: This study aimed to characterize the intron regions of taurocyamine kinase gene (TK) in Opisthorchis viverrini and Clonorchis sinensis, and investigate their genetic variation and population genetics. The researchers found high nucleotide and haplotype diversity in O. viverrini samples, and observed heterozygous patterns specifically in humans with C. sinensis. They suggested that TkD1Int5 could be a high polymorphic genetic marker for further population genetic investigations of these liver flukes and related species.

Summary: The aim of this paper is to investigate and evaluate possible solutions to reduce the environmental impacts of vegetables available on urban markets in Northern Europe, proposing a 4-step solution that can significantly reduce the environmental impact of vegetable production. The study found that local vegetable productions in urban regions can surpass the imported mix on environmental performance in Northern Europe when the right set-up is in place.

Summary: The study developed new or revised definitions for aquaponics and introduced a system analysis approach to explore different aquaponic setups. The new terms 'coupling type' and 'coupling degree' were introduced to better describe water-mediated connections of aquaponic subsystems. This new framework provides a basis for improved communication, uniform metric for comparing aquaponic facilities, and criteria for facility optimization.
