Abstract Camera traps are a mainstream methodology in applied ecology, but surprisingly there no widely accepted protocols to ensure the quality of data obtained from these devices. We reviewed sample 147 articles recent camera‐trapping literature and found that only 4.8% report measure control. propose framework process media files camera minimises errors by adopting series systematic procedures. Before classification, focus is on detecting malfunctions, correcting storage programming...
1. Changes in land use and habitat fragmentation are major drivers of global change, studying their effects on biodiversity constitutes a research programme. However, is multifaceted concept, with functional component linking species richness to ecosystem function. Currently, the interaction between taxonomic components under realistic scenarios degradation poorly understood. 2. The expected (FR)-species relationship (FRSR) positive, attenuated for redundancy species-rich assemblages....
Free-roaming domestic cats can negatively affect wildlife, and understanding how they use space is fundamental to predict their potential impacts. In this study we describe the of 48 owned free-roaming assess level care provided by owners in rural areas near priority conservation southern Chile. Additionally, camera trap data from two protected spatial overlap with wild vertebrates, particularly guigna (Leopardus guigna), a vulnerable forest-dwelling felid. Cat home ranges were variable...
Rainfall has increased in many regions during recent decades, but most information is from dryland ecosystems, which precludes generalizations about its ecological consequences. We explored the effects of flooding on Geoffroy’s cat, Leopardus geoffroyi (d’Orbigny and Gervais, 1844), pampas fox, Pseudalopex gymnocercus (G. Fischer, 1814), exposed to an abnormally rainy period marshes at Mar Chiquita, Argentina. In particular, we assessed (i) habitat use by L. P. gymnocercus, (ii) abundance...
FindingsDarwin's fox (Lycalopex fulvipes Martin, 1837) is an en-demic of the temperate forests Coastal Rangeof southern Chile, that was reported by Charles Darwinin 1834 in Chiloe Island (42° S, 74° W; Martin1837). Initially known exclusively from island, itwas considered both insular subspecies chillafox griseus Gray, (Housse 1953; Clutton-Brock et al. 1976) and a valid species (Martin 1837; Gay1947; Osgood 1943). In 1990, mainland population wasreported at Nahuelbuta National Park (ca. 450...
Abstract Predator assemblages are complex systems in which asynchrony the dynamics of resources and consumers, idiosyncratic perception environmental conditions by predators may obscure detection expected patterns. We disentangle specific effects these variables on guild structure a vertebrate predatory assemblage semiarid ecosystem western South America. Over 16 years, this system faced dramatic fluctuations prey availability associated with four El Niño events. After controlling for other...
Understanding the effects of global climate disruption on biodiversity is important to future conservation efforts. While taxonomic diversity widely studied, functional plants, and recently animals, receiving increasing attention. Most studies mammals are short-term, focus temperate habitats, rely traits described in literature rather than generating from observations. Unlike previous studies, this long-term field study assessed factors driving small-mammal assemblages dry tropical forests...
1. Within mainstream ecological literature, functional structure has been viewed as resulting from the interplay of species interactions, resource levels and environmental variability. Classical models state that interspecific competition generates segregation guild formation in stable saturated environments, whereas opportunism causes aggregation on abundant resources variable unsaturated situations. 2. Nevertheless, intrinsic constraints may result species-specific differences resource-use...
Environmental factors are hypothesized to affect the functional diversity of assemblages hierarchically. First, ecological filters constrain range traits potentially displayed by an assemblage determining its taxonomic composition. Second, some determine actual through phenotypic plasticity species. Little is known about relative importance each set and, using a priori information, most empirical studies report only variability expected from species turnover and neglect that associated...
In Chile, bottom trawling for squat lobsters is one of the most important crustacean fisheries. The fishery has been monitored past 15 years to assess resource status, spatial distribution and effects on benthic species. Understanding interactions fishing non-fishing activities with communities critical importance estimate potential bycatch economic species from operations determine adequate temporal bans. this study we characterised community main non-target caught during historical lobster...
Abstract Arid ecosystems are strongly limited by water availability, and precipitation plays a major role in the dynamics of all species arid regions, as well ecosystem processes that occur there. However, understanding how biotic interactions mediate long‐term responses dryland to rainfall remains very fragmented. We report on unique large‐scale field experiment spanning 25 yr three trophic levels (plants, small mammal herbivores, predators) northern Chilean Mediterranean Region where we...
The Darwin's fox (Lycalopex fulvipes) is one of the most endangered carnivores worldwide, with risk disease spillover from domestic dogs being a major conservation threat. However, lack epidemiologic information about generalist, non–dog-transmission-dependent protozoal and bacterial pathogens may be barrier for prevention management. To determine exposure some these agents in populations, 54 serum samples were collected 47 foxes Southern Chile during 2013–18 assessed presence antibodies...

Alternative Biome States theory (ABS) helps to explain the presence of open biomes (grasslands, shrublands) in environments sufficiently warm and humid for development forest biomes. In these it is possible find areas dominated by that, according this theory, respond mainly fire herbivory. The aims work are identify whether there different types biome-open biome ecotones based on woody composition, describe them explore their relationship with livestock management environmental variables,...
We present comments on an article recently published in Ecology and Evolution ("High-resolution melting of the cytochrome B gene fecal DNA: A powerful approach for fox species identification Lycalopex genus Chile") by Anabalon et al. that reported presence Darwin's (Lycalopex fulvipes), a temperate forest specialist, hyperarid Atacama Desert northern Chile. argue this putative record lacks ecological support light ongoing research endangered species, contains numerous methodological flaws...
