Factors affecting presence and relative abundance of the Endangered volcano rabbit Romerolagus diazi, a habitat specialist. ORYX 2021.

Abstract
AbstractHabitat specialists are particularly vulnerable to extinction when habitat conditions are altered. Information on the habitat use of such species is thus important because it provides insight into factors that influence distribution and abundance, which is crucial for conservation. Here, we aimed to identify factors that influence the patterns of presence and abundance of the Endangered volcano rabbit Romerolagus diazi, a rare leporid with a patchy distribution. Through exhaustive sampling of its range in the Sierra Chichinautzin and Sierra Nevada volcanic fields, Mexico, and using generalized linear models, we found that the probability of patch occupancy was higher where bunchgrass cover exceeded 75%, rock cover exceeded 5%, no cattle grazing was observed and human settlements were at least 7 km away. Patches with greater relative abundance were those with similar characteristics, but located at elevations > 3,600 m, and with rock cover < 15%. Cattle grazing was identified as a major threat to local populations of the volcano rabbit, particularly in the Sierra Chichinautzin. Because of the significance of bunchgrasses for this species, the protection of the mountain grasslands is required in both volcanic fields.

Abstract
Complexity in physical habitats may modify predation pressure by allowing differential access of predators to prey. Rocky subtidal environments are inherently complex with many cryptic micro habitats, such as overhangs and crevices. Here, we examine the influence of habitat complexity in mediating predation on sessile assemblage structure by experimentally manipulating fish access to a range of crevice orientations and sizes. Nine fish species/families were recorded actively feeding within crevices, but australian mado, eastern stripey, wrasses and sawtail surgeon accounted for almost 70% of all entries. Sessile assemblages were influenced by crevice width, fish predation and surface orientation, with more predation activity in larger crevices. Assemblage similarity on upward facing surfaces decreased as crevice width increased. While assemblage structure on downward and vertical surfaces was influenced by crevice width and caging separately. Thus, crevice size and orientation are important habitat complexity features that act to partition predation pressure. This may allow distinct sessile assemblages to persist, even when predation can be intense.
