| Trophic levels are critical for synthesizing species' diets, depicting energy pathways, understanding food web dynamics and ecosystem functioning, and monitoring ecosystem health. Specifically, trophic levels describe the position of species in a food web, from primary producers to apex predators (range, 1-5). Small differences in trophic level can reflect large differences in diet. Although trophic levels are among the most basic information collected for animals in ecosystems, a human trophic level (HTL) has never been defined. Here, we find a global HTL of 2.21, i.e., the trophic level of anchoveta. This value has increased with time, consistent with the global trend toward diets higher in meat. National HTLs ranging between 2.04 and 2.57 reflect a... |

| We analyzed fishermen's local ecological knowledge (LEK) about the feeding habits, trophic interactions, habitats, fishing grounds, migration, and reproduction of nine coastal fishes in Búzios Island, southeastern Brazilian coast. We interviewed 39 fishermen using standardized questionnaires. Fishermen's LEK on habitat use and trophic interactions for the studied fishes agreed with the scientific literature, allowing the organization of reef and pelagic food webs. The interviewed fishermen mentioned that submerged rock formations would be important habitats for some large commercial fishes, such as Seriola spp., Caranx latus and Epinephelus marginatus. In some instances there was no scientific data to be compared with fishermen's LEK, and thus this kind of... |

| The goliath grouper Epinephelus itajara is a large sized (> 400 kg) and critically endangered marine fish, which is protected in many countries, including Brazil. Through the application of semi-structured interviews, we investigated the local ecological knowledge of seven fishermen specialist on catching E. itajara from the Babitonga bay, Santa Catarina, Brazil. Local long-line fisheries for E. itajara seemed to be a disappearing tradition in the studied site, with a detailed inherent local ecological knowledge system, which is also being lost. Our study also showed that fishermen engaged in recent fisheries, such as spear-fishing, can also possess a detailed local ecological knowledge system. Through the analysis of fishermen local ecological... |

| As resilience is observed under circumstances of systemic stress, the various ecological zones of the Pamir Mountains of Afghanistan and the cultural diversity contained within this milieu provide an appropriate setting from which to ask "How can a dynamic concept of pluralism inform adaptation, survival, and resilience in the face of dramatic socio-cultural and environmental change?" This paper asserts that understanding of resilience in coupled socio-cultural and ecological systems is enhanced by the concept of pluralism. The idea of ecological niche is enriched by sensitivity to culture, religion, ethnicity, lifestyle, and habitat. Facilitative relations between the ethnically diverse Kyrgyz and Wakhi, as well as the Pashtu and Shugni, contribute to... |

| This study was conducted in three communities of artisanal fishermen from Ilhabela, located on the northern coast of São Paulo, Brazil. The objective was to analyze the preferences, taboos and medicinal indications of fish and thus representing one of the interactions of fishermen with fish stocks. Data collection was conducted through interviews with the aid of semi-structured questionnaires. We interviewed 25 families, 29 residents in three communities studied during our fieldwork for data collection. Five interviews were done in Jabaquara Beach, 6 in Fome Beach and 14 Serraria Beach. During the interviews, 18 species were cited as preferred for consumption, 11 species considered to be taboo (food prohibited), 5 species were cited as avoided as food, and... |

| Artifacts made from rays (rostral teeth and spine) are very common in shell mounds on the coast of São Paulo, Brazil. The presence of the genus Pristis among the studied species of elasmobranch fishes in this shell mounds reinforces the hypothesis these animals occurred in southeastern Brazil, and were used by hunter-gatherers. I analyzed twelve rostral teeth of the genus Pristis from shell mounds. The teeth have artificial marks left from making arrows and harpoons. The basic function of the teeth found in these shell mounds was the production of tools and ornaments. From the analyzed teeth, ten (83%) were associated to the faunal remain and two (17%) were associated with burials, and they can be considered as ceremonial or votive elements. There had been... |

| This study examined rural Ugandan women's lives to discover reasons why they may or may not practice agroforestry. These women are responsible for the triple roles of reproduction, production and community maintenance work, all carried out within the context of a gendered social environment. From the perspective of the social manifestations of gender, six key factors were identified. The findings were used to create a theoretical model of the interaction between rural women's lives and agroforestry systems. The model shows that agroforestry is not only a biophysical farming system; There is a human component in that interacts with other components to determine the success or failure of an agroforestry initiative. The model can be used to identify and... |
