“…It might be that the urban area close to beavers in Finland consists mostly of recreational cottages that the beavers do not find disturbing or attracting. Earlier studies indicate that even highly used built up areas are not necessarily unfavorable to beavers, as they are known to adapt to the vicinity of humans (Korbelová et al 2016), even in highly urbanized regions (Dewas et al 2012). We used citizen science data in our study, which does not include all locations of lodges in the study area.…”

“…Only wintering lodges should have been reported, but lodges were sometimes very close to each other. Therefore, lodges that were closer than one km to another lodge along a watercourse were counted as the same family group's lodges (Hartman 1994), because family groups' home ranges do not usually overlap (Korbelová et al 2016). Only the centermost lodge in a family group's area was included in the analysis.…”

Differences in habitat use between the native Eurasian beaver and the invasive North American beaver in Finland

2019

Habitat requirements largely determine the distribution and abundance of a species. An invasive species can therefore threaten the survival of a native species, if the two species are similar in niche use. In Finland, the distribution of the invasive North American beaver (Castor canadensis) is approaching the range of the native Eurasian beaver (Castor fiber) possibly creating a threat for the latter. We compared the habitat use of the native and invasive beaver species in Finland in the main distribution of the species and within a smaller area where the species live in sympatry. We compared the used habitats (volume of birch and other deciduous trees and distance to agricultural and urban areas) at beaver lodges and at random locations in the available riparian habitat with (conditional) logistic regression models. Results indicated that the native beaver lodges were located closer to agriculture than those of the invasive beaver. The volume of birch was also slightly greater near the lodges of the native beaver than those of the invasive beaver. However, habitat use of both of the species seemed quite flexible, because the habitat near lodges did not differ much from the available habitat. We conclude that the probability that the North American beaver will invade the distribution area of the Eurasian beaver in Finland depends, at least partly, on the ability of the former to live in proximity to agricultural areas. However, methods other than those related to managing habitat quality may be the best approach to controlling the invasive species.

“…Tomar en consideración evaluaciones que involucren la estación estival podría variar el tamaño del ámbito de hogar y las actividades que la especie realiza como ocurre en otros grupos taxonómicos (Korbelová et al, 2016) De acuerdo a este estudio, se puede afirmar que el individuo estudiado fue muy fácil de detectar y observar, además fue muy activo durante todo el día, especialmente en régimen de marea baja, que fue cuando se le observó caminando, volando, alimentándose, incluso copulando. También se registró actividad en régimen de marea alta, la especie cruzó el cuerpo de agua nadando muchas veces, voló sobre el cuerpo de agua, se acicaló y se alimentó.…”

Selección De Hábitat Del Rascón Plomizo (Pardirallus Sanguinolentus Swainson, 1838) Y Aspectos De Su Etología

Due to the widespread decline of bird populations that inhabit wetlands and the secretive nature of birds, detailed information on habitat use is often difficult to obtain. Pardirallus sanguinolentus Swainson, 1838 is a little studied bird that inhabits wetlands. The reported data about this species are limited to morphological descriptions and aspects of its ecology. However, there is no scientific literature related to habitat use, habitat selection or details of its behavior. Therefore, the goal was to contribute to knowledge about habitat selection and some aspects of its ecology. The work was carried out in the Putemún wetland (42° 25' 37.90" LS and 73° 44' 47.20" LW) under low tide conditions. Habitat selection was calculated using the Manly Selection Ratio after obtaining the home range of the individual studied with the Kernel estimator. Waterbodies were the most important habitatfollowed by muddy beaches at low tide and the third most important habitat component was muddy beaches covered with herbaceous vegetation. The first two types of coverage may have been preferred due to the presence of good quality food (feeding was the most frequent activity in these types of coverage). The species was very easy to detect and observe, and was very active throughout the day, contrary to what was previously reported.

“…De foerageerplaatsen op het land die zich in de nabijheid van water bevinden, behoren daarbij tot de home range terwijl de dammen, holen, burchten en belangrijkste wissels onderdeel van het territorium zijn (Müller-Schwarze & Sun, 2003). De groo e van de home range kan doorheen het jaar verschillen a ankelijk van de kwaliteit van de leefomgeving en lokale popula edichtheden maar ook in func e van het geslacht: hoewel er in de regel geen verschil is in de groo e van home ranges van mannelijke en vrouwelijke bevers (Herr & Rosell, 2004;Korbelová et al, 2016), spenderen mannetjes in het voorjaar meer jd aan de grenzen van het territorium dan vrouwtjes, die op dat jds p van het jaar de jongen zogen (Müller-Schwarze & Sun, 2003;Rosell & Thomsen, 2006). Doorheen de tekst wordt in dit rapport telkens enkel over territorium gesproken in kader van het ac ef verdedigde leefgebied van een familiegroep.…”

“…Een home range benadering met MCP is wel toepasbaar op watersystemen die weinig tot geen meanders hebben zoals meren, kanalen, rechte rivieren, vijvers en poelen. De nadelen van de MCP-methode zijn gekend en veel studies op bevers maken er dan ook geen gebruik van, wat de vergelijkbaarheid van met onze resultaten bemoeilijkt (Graf et al, 2016;Harris et al, 1990;Korbelová et al, 2016). Een bijkomend nadeel van de MCP-methode is dat het moeilijk is de intensiteit van het gebruik van bepaalde zones binnen de home range in te scha en.…”
