In order to explore nest preference main influencing factors Cormorant, medium-sized wetland bird, we analyzed characteristics, Reserve Heilongjiang Province from April October 2019 by Mann-Whitney U test principal component analysis. results showed that: (1) Cormorants preferred areas where trees were relatively short (P<0.05), surrounding shrubs (P<0.01), vegetation coverage was low distance human disturbance far water surface (P<0.05). (2) concealment factor (20.634%), stability (27.614%), (13.901%), (5.782%) loyalty (5.069%). Further analysis tended choose materials moderate thickness, which came dominant vegetation, depth increased with increasing latitude. consistent trade-offs energy domination, feces enhanced characteristics. Based on above results, it suggested that tall should be planted area Reserve.

Visual and olfactory concealment of duck nests: in uence on nest site selection and success
Selecting a nest site is an important decision for waterfowl. Because most nest failure is due to depredation, the primary selective pressure in choosing a nest site should be to reduce depredation risk. This task is dif cult, however, because predators use differing tactics to locate nests, such as olfactory or visual cues. The purpose of this research was to evaluate both the olfactory and vi...
متن کاملDynamic reserve site selection∗
Establishing biological reserves in key habitats is one method of preventing loss of biodiversity. We analyze a dynamic reserve site selection model in which a conservation planner receives a budget each period to purchase sites of heterogeneous cost and ecological value in order to maximize species conserved. Sites chosen as reserved are conserved, while sites left outside the reserve system a...
