Detection histories of mesocarnivores in agricultural areas of Southern Chile
<p>We obtained mesocarnivore detection/non-detection data from 180 sampling units (4 km<sup>2</sup> each) located in the agricultural landscapes of southern Chile from January-April of 2019. We used single-species occupancy models to investigate the associations of forest fragmentation, forest loss, and private land ownership subdivision (as a measure of human use intensification) with the occurrence of four mesocarnivores (güiña, grey fox, culpeo fox, and Molina's hog-nosed skunk), and extended this framework to two-species occupancy models to assess patterns of mesocarnivore co-occurrence with domestic carnivores. We also assessed whether co-occurrence of native and domestic carnivores led to shifts in species' temporal activity.</p> <p>We hypothesized that the occurrence of native mesocarnivores was largely mediated by human use intensification variables only, the occurrence of domestic mesocarnivores only, or a combination of both. Our results largely supported the human use intensification hypothesis, with some influence of domestic mesocarnivores. Mesocarnivore occurrence shifted from a native to a domestic species composition as private land ownership subdivision increased, and native mesocarnivores shifted their behaviour temporally when co-occurring with domestics. In addition, the presence of domestic dogs was associated with an absence of native mesocarnivores, possibly driving a defaunation process in agricultural areas.</p>
Understory specialists in southern Chile
<p><span>The simplification of forest structural complexity, caused by anthropogenic land-use practices, is one of the main threats to understory specialist birds. We examined the association of both single structural attributes and structural complexity, with the density of four understory bird species in the Global Biodiversity Hotspot "Chilean Winter Rainfall-Valdivian Forests" of South America. Between 2011 and 2013, we surveyed habitat attributes and conducted bird point counts in 505 plots in Andean temperate ecosystems in Chile. In each habitat plot, we measured understory density, volume of coarse woody debris (CWD), number of snags, diameter at breast height (DBH) of trees, and leaf litter depth. With these attributes, we developed an index of stand structural complexity (ISC). On average, old-growth forests had higher values for understory density, CWD volume, DBH, and litter depth than secondary</span><span> forests and open fields, and thus greater values of ISC. The density of understory birds was positively correlated with the ISC for the <em>Rhinocryptidae Pteroptochos tarnii</em>, <em>Scelorchilus rubecula</em>, and <em>Scytalopus magellanicus</em>. We also found a positive association between understory density and litter depth, with the density of the <em>Furnariidae Sylviorthorhynchus desmursii</em>. However, this latter species showed a negative association with the density of snags. Our results suggest the utility of using an index of structural complexity, rather than single or even additive habitat attributes, for determining the density of understory specialist birds. We recommend that management plans should promote the retention of habitat attributes that contribute to the structural complexity of temperate forests of South America and beyond.</span></p>
