Summary: The study used proteomics to characterize the secretome of Schistocephalus solidus, a manipulative cestode in its obligatory intermediate fish host. The results showed the presence of molecules with putative host manipulation functions, many of which are species-specific.

Summary: Global climate change can influence the interaction between hosts and parasites, with rising temperatures potentially exacerbating host exploitation by parasites. The study showed that warm temperatures enhanced parasite growth and infectivity to final hosts, while hosts exhibited lower body condition and less active immune system at high temperatures. The data suggests that parasite exposure combined with rising temperatures can shift the host's immunometabolism, providing nutrients for parasite growth and suppressing immune defense.

Summary: In a study on the cestode Schistocephalus solidus, the protein composition was measured under conditions simulating the parasite's transmission from a cold-blooded to a warm-blooded host. Results showed that key enzymes responsible for long-term metabolic changes in the parasite when colonizing a warm-blooded host are induced by temperature.

Summary: This study aimed to describe the excretory-secretory proteins from the helminth Schistocephalus solidus and its intermediate host, the three-spined stickleback Gasterosteus aculeatus L. Mass-spectrometry analysis revealed 215 identified proteins, with infected fish and helminths showing a predominance of components from the immune defense system in their washes.

Summary: The study found that closely related populations often differ in resistance to a given parasite, and these differences may be due to variations in the host's ability to recognize an infection, initiate an effective immune response, and attenuate that response. This suggests that parasite detection, immune initiation, activation speed, and immune attenuation all play a role in the evolution of parasite resistance and adaptations to infection in natural populations.

Summary: Threespine sticklebacks infected with the tapeworm Schistocephalus solidus display impairments in their anti-predator responses and have increased expression of the IMPase 1 gene. The study found that altering myo-inositol levels and inhibiting IMPase 1 activity had effects on the anti-predator behaviors of infected fish, suggesting a potential role for lithium treatment in parasite-induced behavioral changes.

Summary: This study investigates the impact of temperature differences on the interaction between the cestode parasite Schistocephalus solidus and its host, the three-spined stickleback. The findings indicate that temperature is not associated with the host-parasite interaction but can influence host fitness regardless of infection. These results highlight the importance of considering natural settings when interpreting laboratory experiment findings and suggest potential consequences for host demography and parasite transmission dynamics.

Summary: There is a growing concern about the global increase in anthropogenic noise and its negative effects on wildlife. However, the impact of noise on wildlife diseases has received little attention. This paper discusses how anthropogenic noise can influence the occurrence and severity of infectious wildlife diseases. The authors highlight potential repercussions and call for further research to fill the knowledge gaps.

Summary: Through extensive genetic and phenotype analysis of P. vinckei, it was found that the five subspecies have diverged widely and undergone large-scale genome rearrangements. Region-specific selection pressures were observed particularly on genes involved in mosquito transmission. The highland forest subspecies P. v. vinckei has a smaller genome and reduced multigene family repertoire, making it suitable for transfection and ideal for reverse genetics research. Amenable to genetic crosses, P. vinckei isolates show a large degree of phenotypic and genotypic diversity. Their inclusion in studies provides new insights into the evolution of RMPs and multigene families, making them valuable resources for research on parasite virulence and immunogenicity.

Summary: Despite reproducing without sexual recombination, Meloidogyne incognita is an adaptive and versatile phytoparasitic nematode that can parasitize a large range of plants and overcome plant resistance in a few generations. By studying transposable elements (TEs), it was found that TEs play a significant role in driving genomic plasticity in M. incognita and may contribute to species diversification. This study also identified isolate and lineage-specific de novo insertion of TEs, suggesting their potential functional impacts on genomic evolution.

Summary: Fungi plays a critical role in global ecosystems and economies. Canadian researchers face challenges in collaboration and funding for fungal research, but have identified priorities for increasing cooperation, studying diversity, preserving collections, and attracting trainees. The establishment of the Canadian Fungal Research Network aims to strengthen and promote fungal research in Canada.

Summary: The study found that although both hybrids and parents can adapt to DNA damage conditions, hybrids adapt at a slower rate and with a higher cost. This could be due to the interaction between DNA damage and the inherent genetic instability in hybrids.

Summary: The study investigated protein-protein interactions in hybrids between yeast species, finding that most interactions are similar to those of the parents but with some altered instances. It suggests that the occurrence of chimeric protein complexes is frequent, potentially due to incompatibilities or imbalances between parental proteomes.

Summary: This study found differences in the way different lineages of Saccharomyces paradoxus react to environmental conditions during spore activation, with some lineages requiring signals such as glucose and phosphate for activation. This suggests that different lineages may have different adaptive strategies in ecological differentiation and reproductive isolation.

Summary: Most protein complex subunits have small to nondetectable fitness effects when duplicated, with few exceptions. Very few gene duplications affect both fitness and protein-protein interactions. Large complexes like the 26S proteasome are protected from gene duplication by regulating protein abundance.
