“…), and White-tailed deer (Odocoileus virginianus (Zimmermann, 1780)) carrion compose a major portion of Martens diet Duncan 2004, Carlson et al 2014). They are habitat specialists associated with mature northern forests and are of cultural importance to the Ojibwe tribes native to the area (Allen et al 2018b). Martens were found recently within the Apostle Islands National Lakeshore (APIS) after 50 years of apparent absence (Allen et al 2018b), prompting questions about their abundance and distribution throughout the system.…”

Selective pressures (i.e. resource limitation and competitive interaction) that drive the composition of ecological communities vary, and often operate on different ecological scales (ecological variables across varying spatial scales) than observed patterns. We studied the drivers of distribution and abundance of the American marten (Martes americana) and the carnivore community at three ecological scales on a Great Lakes island archipelago using camera traps. We found different drivers appeared important at each ecological scale and studying any of the three scales alone would give a biased understanding of the process driving the system. Island biogeography (resource limitation) was most important for carnivore richness, with higher richness on larger islands and lower richness as distance from the mainland increased. Marten presence on individual islands appeared to be driven by island size (resource limitation) and human avoidance (competitive interaction). Marten abundance at camera trap sites was driven by the cascading effect of coyotes (Canis latrans) on fishers (Pekania pennanti) (competitive interaction). Incorporating three ecological scales gave novel insights into the varying effects of resource limitation and competitive interaction processes. Our data suggests that ecological communities are structured through multiple competing ecological forces, and effective management and conservation relies on our ability to understand ecological forces operating at multiple ecological scales.

“…Sería de gran interés realizar muestreos sistemáticos en busca de la especie en Galicia y el resto de su área de distribución en la Península Ibérica, ya que el conocimiento de la distribución de las especies es una herramienta fundamental en biología de la conservación para conocer sus poblaciones y gestionarlas con eficacia (Lancia et al 1994, Campbell 2004, Barrull et al 2014, O'Mahony et al 2017, Allen et al 2018, Croose et al 2019, siendo la base para la realización de estudios más complejos sobre la ecología de una especie tan poco conocida como la marta. Además, la Península Ibérica representa el límite sur de su distribución, con características mediterráneas, y en Galicia se encuentran las poblaciones más occidentales de Europa, lo que la convierte en una región de gran importancia en la que abordar estudios relacionados con el hábitat y su grado de heterogeneidad y fragmentación, así como con la adaptación de la especie a hábitats tan humanizados como los de Galicia.…”

Pine marten Martes martes is a medium size mustelid that inhabits well-conserved forests of the northern Iberian Peninsula. Currently, the distribution and ecology of the species in the Iberian Peninsula is poorly known. In this work, 27 UTM 10x10km grids in the province of Ourense were sampled using camera-trapping techniques, with the aim of increasing knowledge about the distribution of the species in Galicia. The presence of pine marten was confirmed in 18 of the surveyed grids, which increases the species´ known distribution area by 21% in this community and by 62% in Ourense province, confirming camera-trapping specific survey as a highly effective method to know the distribution of elusive species such as the pine marten.

“…In the early 2000's, researchers found substantial connectivity between black bear (Ursus americanus) populations across the archipelago and high rates of immigration from mainland bear populations (Belant et al 2005). Additionally, the recent discovery of American martens (Martes americana), Wisconsin's only endangered mammal, in the archipelago (Allen et al 2018) has sparked a greater interest in understanding the carnivore community within the park. Despite this, no research has been conducted to describe the distribution of the full suite of carnivore species within the archipelago.…”

Is there anybody out there? Occupancy of the carnivore guild in a temperate archipelago

Carnivores are important components of ecological communities with wide-ranging effects that vary with carnivore size, natural history, and hunting tactics. Researchers and managers should strive to understand both the presence and distribution of carnivores within their local environment. We studied the carnivore guild in the Apostle Islands, w h e r e the distribution and occupancy of carnivores was largely unknown. We monitored 19 islands with 160 functioning camera traps from 2014-2017, from which we collected 203,385 photographs across 49,280 trap nights. We documented 7,291 total wildlife events with 1,970 carnivore events, and detected 10 of the 12 terrestrial carnivores found in Wisconsin. Detection rates for species were generally higher in summer than winter, except for coyotes (Canis latrans) and red foxes (Vulpes vulpes). Finitesample occupancy estimates for carnivores varied across islands, with mean estimated occupancy across islands varying from a high of 0.73 for black bears to a low of 0.21 for gray wolves. Of the potential island biogeography explanatory variables for carnivore occupancy we considered, island size was the most important, followed by distance to the mainland, and then interisland distance. We estimated that terrestrial carnivore species varied in the number of islands they were detected on from 1 island for gray wolves to 13 islands for black bears. Estimated carnivore richness across islands (i.e., the number of carnivores occupying an island) also varied substantively from 1 species on Michigan Island to 10 species on Stockton Island. Island size and connectivity between islands appear important for the persistence of the carnivore community in the Apostle Islands. Nomenclature: List of Mammals (2018).
