Interspecific interactions among sympatric carnivores are critical for understanding patterns of coexistence, competition, and community structure. Among mesocarnivores, dominance hierarchies are typically shaped by differences in body size, social organization, and competitive ability. The golden jackal (Canis aureus) is generally assumed to dominate the red fox (Vulpes vulpes) across shared landscapes, particularly at high-value resources such as carcasses. However, here, we present rare behavioral evidence that challenges this prevailing assumption. Using motion-triggered camera traps deployed at a carcass in Lake Kerkini National Park, Greece, we recorded a sequence of interactions in which a golden jackal displayed clear submissive behavior toward a red fox, including lowered body posture, tail tucking, and conflict avoidance. Subsequent footage revealed two additional agonistic encounters, during which the same red fox successfully displaced two separate jackals, one of which emitted a distress vocalization while retreating. These findings represent the first documented case of interspecific submission by golden jackals toward a red fox and suggest that context-specific factors—such as immediate carcass possession, individual experience, or body condition—may modulate expected dominance outcomes. Our observations underscore the importance of fine-scale behavioral studies in revealing plasticity in interspecific relationships and contribute to a more nuanced understanding of carnivore competition under semi-natural conditions.

Invasive alien species frequently encounter limited natural predation pressure in their non-native ranges, which can contribute significantly to their unchecked proliferation and adverse ecological impacts. Here, we document a novel instance of a livestock guardian dog preying upon an adult coypu (Myocastor coypus) in Lake Kerkini, Greece—a significant observation given the coypu’s status as a prominent invasive species with few natural predators in Europe. The coypu’s presence in the region, coupled with the absence of effective predation among others, has allowed it to establish a robust population and exert considerable pressure on local ecosystems. This novel observation not only highlights an unusual predator–prey interaction involving a domestic mammal traditionally used for livestock management but also provides insights into understanding how domestic animals might inadvertently influence the dynamics of invasive species, potentially serving as a complementary tool in conservation management. By demonstrating that domestic dogs could play a role in controlling invasive species populations, our findings introduce a previously unconsidered aspect of invasive species management with conservation implications.

Water management projects have an important role in regional environmental protection and socio-economic development. Environmental policies, strategies, and special measures are designed in order to balance the use and non-use values arising for the local communities. The region of Serres in Northern Greece hosts two wetland management projects—the artificial Lake Kerkini and the re-arrangement of Strymonas River. The case study aims to investigate the residents’ views and attitudes regarding these two water resources management projects, which significantly affect their socio-economic performance and produce several environmental impacts for the broader area. Simple random sampling was used and, by the application of reality and factor analyses along with the logit model support, significant insights were retrieved. The findings revealed that gender, age, education level, and marital status affect the residents’ perceived values for both projects and their contribution to local growth and could be utilized in policy making for the better organization of wetland management.
