Summary: This study investigates how cascading higher-order interactions (HOIs) affect the population dynamics of a focal species and finds that the 2nd degree HOI significantly reduces survival rate and changes sex ratio. Bayesian analysis suggests unexpected results may arise from complex eco-evolutionary dynamics involving the 1st and 2nd degree HOIs.

Summary: The assembly of plant communities is strongly influenced by recruitment mechanisms, with traits of saplings and established plants playing a crucial role. While certain traits of plants affect recruitment, there is limited evidence supporting trait complementarity in the interaction between canopy and recruit species. Traits also impact seed arrival and soil properties, influencing species abundance in the sapling bank.

Summary: The ability to find food, locate a mate, and avoid predation is crucial for the survival of vertebrate animals. These behaviors require motor control, which is determined by kinematic properties. While we have a good understanding of how locomotor frequency is established, the mechanisms for establishing locomotor amplitude are less well-known. Recent evidence suggests that a subset of excitatory spinal interneurons called V2a interneurons regulate locomotor amplitude in larval and adult zebrafish. This study provides direct evidence that V3 interneurons, a population of ventromedial glutamatergic spinal neurons, are active during swimming in larval zebrafish and may contribute to locomotor amplitude independently of locomotor frequency.

Summary: As global ocean temperatures rise, coral reef health and diversity decline. This study found that an increase in temperatures in the environment of parental colonies of the heat-resistant coral Leptastrea purpurea leads to the release of smaller but greater numbers of larvae, with normal settlement behavior and increased post-settlement survival rates.

Summary: Seed dispersal is crucial for the persistence and spread of plant populations, as most plant species rely on animals to disperse their seeds. Loss of dispersers can lead to changes in plant populations, community patterns, and ecosystem functioning.

Summary: Harmful algal blooms pose a growing environmental concern in aquatic systems. This study found that exposure to the neurotoxin BMAA can impair the development and behavior of larval Fathead Minnows, affecting their ability to capture prey and evade predators. These findings suggest that chronic exposure to neurodegenerative cyanotoxins may alter predator-prey interactions in natural systems by impairing an animal's ability to perceive, process, and respond to relevant biotic stimuli.

Summary: Deoxygenation poses a major threat to coral reefs, causing catastrophic effects such as mass coral mortality. Different coral species have different tolerances to reduced dissolved oxygen concentrations, with some species surviving only a few days while others can tolerate deoxygenation for weeks. This study found that severe deoxygenation had a significant negative impact on recruit survivorship in certain coral species, highlighting the importance of considering species-specific variations in deoxygenation tolerance during reef conservation and restoration efforts.

Summary: Extreme geohazards like volcanic eruptions, earthquakes, landslides, and tsunamis can cause cascading effects with unpredictable risks, which are often overlooked in hazard assessment. Anticipating and preparing for such extreme events is crucial for maintaining safe and sustainable lifestyles. Volcanic islands, such as Tenerife in the Canary Archipelago, have experienced multiple occurrences of cascading extreme hazards in the past, highlighting the importance of understanding and mitigating the potential consequences.

Summary: The study found that intensive hunting and enduring fear of humans have caused forest ungulates like moose to partly avoid areas near human infrastructure, resulting in positive cascading effects on tree recruitment. Reduced browsing pressure and increased tree recruitment were observed near roads and houses, suggesting a weak cascading effect mainly driven by risk avoidance behavior towards humans.

Summary: Multilevel selection on offspring size involves both hard and soft selection, influenced by sperm availability; the study examined egg size within and among clutches. Findings suggest that hard selection is stabilizing, soft selection is directional, and optimal clutch mean egg size differs between mothers and offspring.

Summary: Evolving cells to larger sizes can improve the DIC uptake of the phytoplankton species Dunaliella tertiolecta, leading to faster growth and higher maximum biovolume densities. This study demonstrates that evolutionary shifts in cell size can alter the efficiency of DIC uptake systems and affect the fitness of phytoplankton species.

Summary: Climate change impacts all aspects of biology, causing organisms to adapt or face extinction. However, our ability to predict organismal responses is limited by geographical biases in existing datasets, which do not cover the wide range of climates that terrestrial animals will need to operate in.

Summary: Research showed that there was positive correlational selection on the combination of metabolic rate and colony size in different environments, but there was no direct selection on metabolic rate itself. Although individuals exhibited plasticity in metabolic rate, there was no evidence that this plasticity was adaptive.

Summary: By comparing data from nearly 900 species, the study found that as cell size increases, the ratio of nucleus size to cell size systematically decreases. The evolution of nucleus size appears more constrained compared to cell size, and the relationship in N:C ratios across diverse organisms presents a universal pattern.

Summary: Female size affects fecundity through both batch fecundity and spawning frequency, with smaller females potentially nullifying the hyperallometric contribution of larger females. Spawning frequency scales positively with body size across species, while the relationship between body size and absolute fecundity may be underestimated based on batch fecundity estimates. Further studies are needed to better understand the impact of female size on reproductive output.

Summary: This study empirically assessed how species diversity affects biomass and energy fluxes in phytoplankton communities. Diverse communities produced net energy and biomass at faster rates, reaching greater maximum biomass but with no difference in maximum net energy production. Competition limits energy fluxes as biomass accumulates over time.

Summary: The distribution and abundance of disease vectors like mosquitoes are changing due to factors such as climate change, invasions, and vector control strategies. Most models currently ignore the nonlinear relationship between wing length and reproduction in mosquitoes, leading to potential biases in population growth estimates. Incorporating hyperallometric relationships in future disease vector models is crucial for accurately predicting changes in mosquito distribution.

Summary: Research has shown that populations with higher metabolisms have higher intrinsic rates of increase and lower carrying capacities, in accordance with classic theory, but there are also important departures from the theory. It is believed that resource supply is independent of metabolic rate, but under real-world conditions, this assumption is violated, potentially leading to far-reaching consequences for the management of biological systems.

Summary: Research shows that the assumption of isometry in the management models of fisheries leads to an overestimation of the replenishment potential of exploited fish stocks, risking systematic overharvesting. By considering hyperallometric reproduction, management strategies could be optimized to increase yields and maintain target replenishment levels.
