Summary: A female canid with intermediate characteristics between a domestic dog and a pampas fox was found in Vacaria, Brazil. Genetic analysis confirmed it to be a hybrid between the two species, which is the first documented case of such hybridization in South America. This finding poses a threat to the conservation of wild canids, and further studies are needed to understand its genetic, ecological, and behavioral consequences.

Summary: This study aims to characterize the changes to the bones and teeth of prey caused by the Pampas fox. Through the analysis of faeces, plant remains, invertebrate remains, and vertebrate bones and teeth were identified. The study found a high frequency of bone breakage, a low frequency of tooth marks, and a high frequency and intensity of digestion damage. The information generated from this study contributes to the understanding of accumulation processes in archaeological and paleontological sites in South America.

Summary: The red fox is the most abundant mesopredator in Central Europe, and understanding their feeding behavior is important for ecology and wildlife management. This study analyzed the diet of fox cubs and adult foxes over 3 years in a marshland in Hungary. The results showed that adult foxes optimize their diet based on the yearly abundance of prey, while cubs are provisioned with high-energy food. This foraging strategy contributes to the ecological success of the red fox.

Summary: The increasing impacts of wildfire on arid regions due to climate change highlight the necessity of understanding the response of natural communities to fire. A study conducted in northern California investigated the use of and diets within burned and unburned habitats by black-tailed deer before and after a large wildfire. The study found that deer increased their use of unburned sites and reduced use of burn sites immediately after the fire, but started returning to burned sites in subsequent years. The diversity of the deer's diet was lower in burn sites post-fire, dominated by oak, but increased in subsequent years with more herbaceous plants in burn sites.

Summary: Finding a common currency for benefits and hazards in optimal foraging theory is challenging. We propose a new analytic approach that incorporates the nonlinear effect of predation risk and provides a quantitative measure of the trade-off between foraging rewards and hazards. We compare optimal decision-making dynamics for different foraging life-history strategies, showing that foragers with delayed-benefit strategies are more sensitive to predation risk.

Summary: Anti-inflammatory diet is beneficial for reducing the risk of NAFLD in US adults. The DII is a stronger predictor of hepatic measures than the TAC, and future studies on hepatic health should use the DII to estimate dietary inflammatory potential.

Summary: This study used a multi-stage sampling strategy to survey First Nations adults living in Ontario. Linear programming was applied to create dietary models for the 100 most consumed food groups by men and women. The study found that contemporary First Nations diets deviated from healthier historic diets, suggesting the importance of including traditional foods in a culturally appropriate diet.

Summary: Adopting a sustainable diet is crucial in addressing obesity, undernutrition, and climate change. The development and validation of a Sustainable Diet Index (SDI) among Malaysian adults aim to measure the level of healthy and sustainable diet behavior, incorporating indicators such as rice, animal-based food, plant-based food, food waste, and packaging.

Summary: The EPIC FFQ showed good agreement with the 24-h dietary recall method in Lebanon, with statistically significant correlations between dietary intakes. This indicates that the EPIC FFQ can be considered a valid tool for assessing diet in epidemiological studies among Lebanese adults.

Summary: Using machine-learning models, individualized treatment rules were developed based on data from participants to determine that for most participants, the D + E intervention was optimal, but there was evidence suggesting some participants may benefit more from diet alone for certain outcomes.

Summary: This research aimed to validate an online survey assessing decisional balance for consuming a whole food plant-based diet (WFPBD) among US adults, describing attitudes and beliefs towards adopting a WFPBD, and evaluating socio-demographic differences in decisional balance. The survey was reduced to 12 items and demonstrated invariance across socio-demographic variables, with high reliability for the subscales in the final model. Results showed significant associations between decisional balance and self-reported dietary patterns, indicating the potential for interventions promoting WFPBD consumption in the US.

Summary: The prey ranking and handling costs of animal resources in Central Western Argentina are explored in this study. For the first time, handling costs are incorporated into the ranking, resulting in the guanaco, Rheidae eggs, and armadillos being identified as the top-ranked resources. The development of the diet-breath model (DBM) in different environments supports the optimal foraging theory and provides insights into human subsistence strategies.

Summary: The conflict between pumas and livestock producers is mainly caused by loss of livestock, leading to persecution and hunting of pumas by humans. Factors such as high livestock density, low latitudes, and low habitat steepness have been identified as predictors of puma-livestock conflicts. Common conflict mitigation techniques include improving livestock management, predator control, and the use of fencing.

Summary: Understanding the food habits of mammalian carnivores, especially the puma, helps comprehend the important role of apex-predators in maintaining healthy ecosystems. This study found that wild prey, both exotic and native species, are the main food sources for pumas in the South American temperate region, despite frequent conflicts with humans. Exotic species have a higher occurrence frequency in puma diets, while livestock is more common inside protected areas.

Summary: Conservation biology is a discipline that requires collaboration between conservation and science, as it encompasses social, political, and ecological aspects. In a comparative study of 7 cases, motivations for collaboration, potential collaborators, and effective collaboration strategies were examined. The study found that successful conservation outcomes were prioritized in 5 cases, while livelihood benefits were prioritized in the other 2 cases. Participatory approaches were employed in all case studies, with multiple external actors playing a crucial role in enhancing conservation and sustainability outcomes. Key aspects of collaboration considered across the case studies included time, trust, tools, and transformative potential. Guidelines for successful collaboration were developed, emphasizing long-term commitment, knowledge integration, multiscalar and plural approaches, trust-building, appropriate engagement, evaluation, support for students, and efforts for transformation.

Summary: The study found that puma predation on livestock is considered a significant cause of livestock loss in the Argentine Dry Chaco region, leading to low tolerance towards pumas. While attitudes towards pumas were not strongly correlated with predation, respondents who experienced livestock predation were more likely to engage in retaliatory hunting.
