An integrated assessment of niche partitioning reveals mechanisms of coexistenc...
Barros, Ana Luisa; Raposo, Diogo; Almeida, João David; Jesus, Hugo; Oliveira, Maria Alexandra; FERNANDES, CARLOS; MacKenzie, Darryl I.Species diversity depends on the capacity of species to coexist, and when these share similar ecological requirements some degree of partitioning of the ecological niche is expected. Within the order Carnivora, direct and indirect interspecific interactions shape community structure and composition. Although strong negative interactions (e.g., interspecific killing) are expected between large carnivores and sub...
Assessment of technological developments for camera‐traps: a wireless transmiss...
Barros, Ana Luisa; Alcobia, Sandra; Gonçalves, Paula Isabel; MacKenzie, Darryl I.; Santos-Reis, MargaridaCamera-trapping is considered a cost-efficient method to monitor wildlife, but relevant performance constraints remain. We assessed performance and cost-benefit for 2 recent technological innovations: (i) a wireless transmission system where cameras communicate in a network, and (ii) using solar panels as a camera's sole power supply. The maximum distance between cameras that ensured wireless connection varied ...
Do Mesocarnivores Respond to the Seasonality in Management Practices in an Agro...
Barros, Ana Luisa; Raposo, Diogo; Almeida, João David; Alcobia, Sandra; Oliveira, Maria Alexandra; MacKenzie, Darryl I.; Santos-Reis, MargaridaIn the Mediterranean, we find a mosaic of natural and cultural landscapes, where a variety of forest management practices created intermediate disturbance regimes that potentially increased biodiversity values. Nonetheless, it is essential to understand the species’ long-term response to the dynamic management in agroecosystems, since the species tolerance to disturbance can change throughout the life cycle. Ma...
Comparing the performance of two camera trap-based methods to survey small must...
Barros, Ana Luisa; Marques, Margarida; Alcobia, Sandra; MacKenzie, Darryl I.; Santos-Reis, MargaridaSmall mustelids are an understudied group partly due to the challenges in detecting and monitoring their populations. Despite the classification as Least Concern for several small mustelid species, some studies indicate a population decline in parts of their range. Therefore, efficient and group-specific methods are essential to support monitoring efforts. Camera traps are widely used, particularly to monitor c...
