Summary: The examination of spawning and maturity traits in three coexisting Platycephalus species in southeastern coastal waters of Australia revealed commonalities among them. These species displayed gonochoristic reproduction, prolonged reproductive activity, asynchronous oocyte development, and likely multiple spawning events throughout each spawning season. Males matured at smaller sizes and younger ages than females, with skewed sex ratios indicating divergent growth characteristics. Reproductive isolation among species is likely maintained through behavioral and morphological factors, as well as depth-related separation. Similar reproductive strategies among these species and other sympatric coastal teleosts suggest ecological adaptations to a variable coastal environment.

Summary: Dietary partitioning plays a central role in biological communities and its extent varies over time, possibly due to food availability and seasonality. The study found that dietary partitioning is greatest when food abundance is low, implying competition for limited food resources. The extent of dietary partitioning in birds and mammals is also related to seasonal changes in primary productivity.

Summary: Classic evolutionary theory suggests that sexual dimorphism evolves primarily through sexual and fecundity selection. However, recent research indicates that resource competition may also contribute to the evolution of sexual dimorphism through ecological character displacement between sexes. This study conducted a meta-analysis to examine the association between isotopic divergence and body size dimorphism, and found modest but significant positive associations, particularly when there was a greater ecological opportunity for dietary divergence between sexes.

Summary: This study analyzed the diet and distribution of native and exotic Loricariidae fish from a Neotropical floodplain and found that these factors contribute to the coexistence of different species. Differences in diet and resource utilization promote coexistence, but the large population size of exotic species may pose a competitive threat to native species.

Summary: The study compared stable isotopic ratios of Didelphidae and Sigmodontinae in four Brazilian biomes, revealing different resource partitioning strategies between the two clades. In the Atlantic Forest, the niche occupation by Didelphidae was completely enclosed within the trophic niche of Sigmodontinae, while in the Cerrado, both clades showed a broader trophic niche.

Summary: An analysis of metagenomic sequencing of stool samples reveals the association between gut microbiome and response to immune checkpoint blockade therapy in melanoma patients. However, there is limited consistency in the microbiome-based signatures across different populations. Future studies should consider larger sample sizes and examine the complex interplay between clinical factors and the gut microbiome.

Summary: The bluelined goatfish can exhibit dynamic body colour changes, transforming from a pale, buff/white pattern to a red pattern when foraging. The study shows that they possess color vision and can discriminate colors in the long-wavelength region, such as the red body pattern. This ability may provide an advantage in recognizing visual signals from conspecifics in the marine environment.

Summary: The endangered soft coral Dendronephthya australis is experiencing population decreases in central eastern Australian waters. Genetic analysis reveals that it is a single species within the Nephtheidae family, with genetic differentiation observed among different locations. Seahorse Gardens and Ettalong have higher genetic diversity, potentially serving as ancestral populations.

Summary: Aged plants are more resistant to PVY infections compared to young plantlets. However, the impact of inoculation date on PVY accumulation in daughter tubers has not been studied. Early and late PVY inoculations both result in similar rates of infected tubers and equivalent viral accumulation.

Summary: Since the mid-2010s, several emerging clones, including EU_37_A2, have been replacing the dominant Phytophthora infestans clones in Western Europe. The success of EU_37_A2 can be attributed to its decreased sensitivity to the fungicide fluazinam and shorter latent period. However, the competitive advantage of EU_37_A2 over the other virulent clone, EU_13_A2, cannot be fully explained. The emergence of EU_37_A2 was also slowed down by the reduction in the use of fluazinam.

Summary: The genus Smeagol includes five named species of air-breathing marine slugs, with restricted distribution to southern Australia, New Zealand, and southern Japan. The critically endangered S. hilaris from New South Wales has had a known distribution limited to Merry Beach. This study surveyed the known population at Merry Beach and discovered a new population at Storm Bay, doubling the known global populations of this species. DNA barcoding confirmed the conspecificity among the populations and recommendations for ongoing management are provided.

Summary: Human impacts have led to a rapid and extensive decline of marine biodiversity. This study focused on the understudied group of marine flatworms, specifically in southeastern Australia. By assessing the diversity and abundance of flatworms at boulder beaches, hotspots of occurrence were identified, with Bottle and Glass in Sydney Harbour being the most diverse site. The study also found that flatworms were more common under large boulders and less exposed beaches, as well as at higher latitudes.

Summary: Studies show that consumer drones have little visible impact on the behaviors of estuary stingrays in New South Wales, Australia, but potential physiological responses cannot be ruled out. It is recommended to fly the drone at the highest possible altitude that allows monitoring of features of interest. Drones are concluded to be effective tools for assessing natural stingray behaviors.

Summary: This study explored the rapid colour change in the bluelined goatfish, which can change from white to red stripes in a matter of seconds. The research found that this rapid colour change is associated with feeding and may serve as a signal to conspecifics and heterospecifics. This ability to change colour rapidly provides protection and facilitates social communication.
