Summary: This study conducted phylogenetic analysis on the rove beetle subfamily Tachyporinae and proposed a revised classification based on morphological characters and phylogenetic analyses. The results rejected the monophyly of Tachyporinae and its largest tribe Tachyporini, providing a new framework for taxonomic inventories and ecological studies.

Summary: The study focused on the physio-morphological responses of northern tree species to climate change, with provenance and light intensity significantly influencing intrinsic water-use efficiency and diameter at breast height. The results highlighted the importance of selecting balsam fir based on stomatal conductance, shade tolerance, and consistent growth under variable climatic conditions for sustained growth under projected forest dynamics accompanying changes in regional climate. Temperature variables were strong indicators of diameter at breast height increment, while the relationship between intrinsic water-use efficiency and radial growth was evident.

Summary: The presence of four Ditylenchus species, including three new records in Canada, in cultivated areas of southern Alberta was documented. Accurate species identification of these nematodes is crucial for implementing appropriate management strategies. The morpho-molecular characteristics and phylogenetic relationships of these species were described, providing valuable information for nematode management programs.

Summary: Intertidal seaweed beds provide habitat for various species, and the management of seaweed harvesting should consider the impact on both biomass and morphology. A study conducted in southern New Brunswick, Canada compared the morphology, vertical distribution of biomass and shoots of Ascophyllum nodosum from harvested and control sites. The research found that the harvest had no significant impact on the vertical distribution of shoots or biomass within individual clumps. Additionally, there was no significant difference in the biomass of littorinids, the main invertebrates inhabiting the seaweed beds, between control and harvested sites. Overall, the current regulations for A. nodosum harvest in New Brunswick do not have long-term effects on algae morphology or abundance of its main inhabitant.

Summary: This study examined the concentrations and compositions of polycyclic aromatic hydrocarbon (PAH) contaminants in the surficial sediments of the Saint John Harbour (SJH) and assessed PAH exposure to local aquatic biota. The study found that sedimentary PAH contamination in the SJH is heterogeneous and widespread. Some sites exceeded recommended guidelines for the protection of aquatic life. However, no indication of effects on local nekton was observed.

Summary: This study explored the client experiences of midwifery in New Brunswick and found high satisfaction among participants, who identified several key factors contributing to quality midwifery care. Despite systematic underfunding of reproductive health care in the province, clients celebrated the expertise and competence of midwives.

Summary: Incoming federal regulations in Canada will require the phase-out of coal-fired electricity production. The study focuses on the economic impacts of this shift in New Brunswick and finds that phasing out coal would result in small reductions in GDP but significant reductions in CO2 emissions. Reinvesting in alternative energy sources would further reduce GDP, consumption, and investment. The most cost-effective approach would be reinvesting capital in nuclear and hydro power.

Summary: Three dogs died after visiting the Wolastoq (Saint John River) near Fredericton, New Brunswick, in Atlantic Canada in July 2018. Toxicosis was observed in all dogs, with necropsies revealing pulmonary edema and brain hemorrhages. Analysis confirmed the presence of anatoxins in vomit, stomach contents, water, and biota, indicating the role of these neurotoxic alkaloids in the dog mortalities.

Summary: Three new species of Tachinus subgenus Latotachinus from China are described, with two sharing reduced elytra, lack of wing-folding patches on the abdomen, and microsculpture on the head and pronotum. Another species is morphologically similar to a species in eastern China but differentiates based on abdominal setae. This increases the number of Latotachinus species from four to seven, with a provided distributional map and key for all known species.

Summary: The study indicates that clam harvesting can significantly influence sediment pH conditions and clam densities. Higher sediment pH conditions and clam densities are often observed in harvested areas, while higher clam abundances are found at sites with lower pH conditions, suggesting a potential restriction of this effect at small spatial scales.

Summary: The Pabineau Lake Mo occurrence in northeastern New Brunswick consists of high-grade molybdenite-bearing granites within the Pabineau Falls Granite. Geochemical and geochronological data suggest that the molybdenite is hosted by an intrusion distinct from the PFG, likely associated with granites of the Appalachians orogenic system. The presence of mafic elements and sedimentary components in the host rock implies a complex origin involving multiple sources and processes.

Summary: Interactions between cyanide leach and cinnabar-bearing gossan tailings have resulted in Hg-contaminated groundwater that discharges to Gossan Creek. The presence of naturally occurring cinnabar complicates the identification of mining-related contamination. The study analyzed surface water data to assess the impact of mining-associated elements and found evidence of migration towards Gossan Creek.

Summary: Two new species of the scydmaenine genus Stenichnus, Stenichnus bifurcatus and Stenichnus totoroides, are described based on specimens collected in Taiwan. Additionally, new records and first-time records are provided for several known species, and descriptions of six undescribed Japanese species are given to facilitate future research on the diversity of this genus in the Eastern Palaearctic region.
