Summary: This study examined the drivers of moose population growth and found that negative density-dependent population growth and predation were the main factors limiting population growth. Harvest activities were also found to contribute to population declines. The study highlights the complex relationships between natural and human-caused mortality in driving ungulate population dynamics.

Summary: This study examines the effects of dehorning on black rhinos in Namibia and finds no significant difference in variables such as age at first reproduction, inter-calving interval, birth sex ratios, calf survival, and lifespan between dehorned and horned individuals. It suggests that dehorning is an effective anti-poaching technique for black rhinos.

Summary: Estimating population parameters, performance, and factors influencing reproduction from long-term monitoring data is crucial for effective wildlife management and conservation. In this study, we synthesized 20 years of individual-based monitoring data on black rhinoceros in Namibia and found that the metapopulation is performing well despite the arid landscape. Information-theoretic modeling revealed the influence of vegetation index on age at first reproduction and rainfall on inter-birth interval, indicating potential impacts of browse quality and rainfall on different reproductive parameters. This study contributes to our understanding of black rhinoceros population dynamics and enhances our ability to manage the population in Namibia.

Summary: The study found that suspending black rhinoceroses by their feet did not significantly compromise their respiratory gas exchange compared to lateral recumbency, and could even slightly improve gas exchange. Additionally, black rhinoceroses immobilized with etorphine and azaperone were not as hypermetabolic as white rhinoceroses immobilized with etorphine.

Summary: Major disturbances can temporarily remove constraints on population abundance and distribution, allowing ungulate populations to rapidly grow and expand into less-preferred habitats. The recovery of waterbuck population in Gorongosa National Park is marked by demographic skewness and shifts in diet selection, enabling them to tolerate the costs of density-dependent spillover in the short term. Plasticity in foraging behavior and diet selection play a key role in individual-level mechanisms during population recovery.

Summary: The survival of juvenile ungulates has a significant impact on population dynamics in ecosystems. This study analyzed the relationship between the survival of moose calves and factors such as carnivore occurrence, habitat productivity, weather, human harvest, and migratory behavior. The study found that regions with higher bear densities had higher calf mortality rates, and calf survival was lowest in the presence of wolves and deep snow. Calf survival was also negatively correlated with the proportion of clearcuts and young forests within the mother's home range. Additionally, calves of stationary females had higher survival rates compared to migratory individuals.

Summary: Research has shown that annual quotas of 6000 grey seals, with 50% of hunted seals being young of the year, can reduce predation on commercially valuable prey species, but overhunting may lead to decreased seal abundance. Strategies targeting higher proportions of young-of-the-year seals are less likely to trigger conservation concerns, but require larger quotas to achieve removal targets.

Summary: Increased exportation of forest harvest residues due to higher demand for woody biomass has led to soil mineral resource depletion and negative effects on tree nutrition and growth. Removing harvest residues and litter significantly reduces tree growth and wood density in young beech and oak forest stands.

Summary: The study evaluated the effects of corn-planting population and maturity stage at harvest on forage yield, silage quality, and fiber digestibility. Increasing planting population may increase forage yield, but the effect varies with soil's growing potential. There is no significant interaction between planting population and maturity stage for forage quality and fiber digestibility.

Summary: The population dynamics of mutualisms tend to exhibit stable coexistence at high density and destabilizing thresholds at low density, regardless of the level of detail, types of benefits, and inspiring systems. These dynamics are caused by saturating benefits of mutualism, whether due to intrinsic or extrinsic density dependence factors, such as Allee effects. Overall, there exists a robust population dynamic theory of mutualism that can make general predictions.

Summary: This study aimed to investigate the association between serum lipopolysaccharide-binding protein (LBP) and potential effects on bone density, quality, and turnover in men. The results showed that LBP was associated with lower bone density at the mid-forearm and broadband ultrasound attenuation measure in heavier participants. However, the data did not support clear associations between serum LBP and bone health.

Summary: The study found that controlled harvesting of saltwater crocodiles since protection has not had a negative impact on population size and structure. By simulating different harvesting scenarios, it was discovered that adult survival rates have a significant influence on the population's sustainability.

Summary: This study focuses on the urban sustainability and applies geographically weighted regression and movement stratification regression to analyze the relationships between carbon emissions and urban population size, density. The results indicate that there are different scaling modes between urban size and carbon emissions, and the impact of urban density on different types of carbon emissions also varies. Additionally, the population size of the urban area also influences the relationship between carbon emissions and urban density.

Summary: This study uses big data to investigate the incidence and epidemiological characteristics of infectious diseases in a population of 3,987,573 individuals in Shandong province, China. The results show that infectious diseases remain a significant public health problem, and non-notifiable diseases should not be neglected.

Summary: Over the past 1000 years, New Zealand has lost a significant number of bird species, with a majority of extinctions attributed to predation by introduced mammals. Effective mammal control measures have shown positive population-level responses in large, deeply endemic forest bird species, while the impact on shallower endemic and nonendemic species tends to be less significant.

Summary: Conservation issues are complicated by sociopolitical controversies reflecting competing philosophies and values. Effective outcomes require engagement with diverse influences. Acknowledging personal values and disciplinary paradigms is essential for generating solutions. The ongoing reliance on normative values in conservation suggests the need for formal reflexivity methods in research. Adoption of such methods can lead to more socially just conservation outcomes.

Summary: Rats, as invasive mammalian predators, pose a major threat to ecosystem functioning globally. This study developed a new sensing paradigm using a specific rat urine biomarker to detect and monitor the presence of rats more sensitively and at a lower cost. The researchers successfully selected aptamers and characterized their affinity and specificity towards the biomarker. The developed biosensor platforms showed high specificity and nanomolar range dissociation constants, indicating their potential for remote surveillance of rats.
