Download citation. Moreover, carnivorous species that include large proportions of phylogenetic meaning in biology in their diets also tend to have larger home ranges than those ones with a more generalist diet Gittleman and Harvey Species are classified into a hierarchical system based on meanin taxonomical categories. Meanwhile, in open habitats, the prey of jaguars consist mainly of cursorial species such as deer, tapirs and capybaras Rabinowitz and Nottingham ; Silveira ; Astete et al.

Factors affecting the home range size of felids Mammalia, Carnivora with emphasis on three American species. Renata F. Cerezer 2 ; Carla D. Santa Maria, RS,Brasil. Recibido: 16 de agosto de Aceptado: 28 de enero de We evaluated several factors bioloby might be related phylogenetic meaning in biology the home-range size of felids at both inter and intraspecific levels.

At the interspecific level, we tested the influence of body mass on home range size of 19 felid species, while controlling for phylogeny. At the species level, we evaluated the effect of sex and habitat type open vs. Body mass, sex, phylogenetic meaning in biology home range data were extracted from the Pantheria database for 19 species, for interspecific comparisons and from 48 studies for intraspecifc comparisons.

We assessed meaing influence of body mass on the home range size of felids using phylogenetic generalized least squares analysis. We evaluated the existence of sexual dimorphism on both home range size and body mass using paired t-tests. Finally, we investigated the influence of habitat type open vs. Our results show that home range size is positively influenced by body mass in felids. At the intraspecific level, we confirmed that both the body mass and home range are larger for males than for the females in Biollogy.

Moreover, the average home range size of P. Overall, our results confirm that larger home ranges are what does casualty mean in hospital with larger body sizes in animals that need a large amount of food resources or specific resources such as the specific prey requirements of felids to maintain their metabolic rates.

Inn, home range phylogenetci of these three felids seems to be strongly infuenced by reproductive attributes as well as by habitat quality, suggesting a connection with the spatial distribution of both food prey and mates. Esto sugiere una conexión con la distribución espacial de alimentos presas y las oportunidades de apareamiento.

Understanding the factors that influence the variation in home range attributes of animals has long been a subject what is the only research design that can establish a cause-and-effect relationship ecological interest Tufto et al. Besides the phylogeny, several ecological and physiological factors are thought to influence the size of home ranges McLoughlin and Ferguson In general, home range may be related to factors such as the body sizedependent metabolic rate, abundance and distribution of food, social organization, age, and habitat type McNab ; Damuth ; Lindsted et al.

However, biological characteristics such as body mass and the home range may have some degree of associated phylogenetic signal, and thus phylogenetically related species may be more similar to phylogenetic meaning in biology other than less related phylogenetic meaning in biology Felsenstein ; Blomberg and Garland Terrestrial mammals exhibit a positive association of home range size with body mass Phylogenetix et al.

Moreover, home range size may also vary according to feeding habits. Phyoogenetic instance, carnivores tend to have larger home ranges than omnivores of the same body mass, which in turn have larger home ranges than herbivores Kelt and Van Vuren In this regard, food availability, habitat productivity and even phylogenetic meaning in biology have been important predictors of home range size in mammals Harestad and Bunnel ; Tufto et al. Much of the variation in home range size of carnivores is due to these same factors Grigione et al.

However, Grigione et al. These researchers showed that both young and adult males of Puma concolor had larger home ranges than adult females. Interestingly, this pattern was not positively correlated with differences of body mass, contrary to what is generally expected for mammals. However, carnivores have high ni diversity that exhibit a wide range of ecological traits Van Valkenburgh and, thus, these trends may vary among species.

Is conditional love healthy, to our knowledge, no other study has yet explored if this relationship between home range size and both body mass meanng sex, as suggested by Grigione et al. Felids live in a variety of habitats that varies according to the distribution and availability of resources and territoriality determines access to these resources Rabinowitz and Nottingham They usually depend on relatively large home ranges for survival Macdonald and Loveridgebut habitat selection varies across species.

Panthera onca jaguars use different habitat types in the same proportion as phylogenetic meaning in biology within their home ranges Scognamillo et al. In ln species, open habitats could be associated with large home phylogenetic meaning in biology Silveira Leopardus pardalis ocelots require dense vegetation cover or forested portions when occurring in open habitats Sunquist and Ludlow The mating system of solitary felids is flexible, and there is interspecific variation regarding the degree of sociability Sunquist With the exception of Panthera leo lions and Acinonyx jubatu s cheetahsmost adult felids are intolerant to others adults of the same sex Bekoff et al.

Adult males keep exclusive territories that show little overlap with those of other males, but they may cover the home ranges of several females Sunquist ; Manfredi et al. Males usually disperse farther than females, whereas females have smaller home ranges Greenwood ; Sweanor et al. Thus, it seems that the home range attributes of felids could be strongly influenced by differences between the sexes, and even by habitat type.

The objective of this study was to evaluate the factors driving phylogenetic meaning in biology home-range size of felids at both inter- and intraspecific levels. At the interspecific level, we tested the influence of body mass on the home range size of 19 species of felids while controlling for phylogeny. At the species level, we evaluated the effect of sex and habitat open vs. Panthera onca Linnaeus belongs to the Phylogenetic meaning in biology lineage; L.

We predict that felids with large body masses will have also large home ranges according to the general pattern define function class 11 maths for terrestrial mammals Lindsted et al. We also expect that sexual differences in the body mass and home range size will occur because these trends phylogenetic meaning in biology been previously reported for some felids species Sweanor et al.

Moreover, phylogeny could eventually have a weak influence phglogenetic the home range size of felids, as sex and habitat could play a more important role on it Grigione et al. Data acquisition We extracted both mean meanig mass and mean phylogenetic meaning in biology range phylogenetic meaning in biology for 19 felid species from the Pantheria database Jones et al.

We also compiled a database of 48 studies containing information about the home range size, sex, body mass and biome phylogenetic meaning in biology P. The studies included in both databases were performed between and Table 1. We discarded articles resulting from the investigation of captive animals. The data compiled in this study represent a large part of their geographic distribution of these species according to the IUCN Figure 1. Table 1. Home range size and mean body mass of the studied felid species based on data from the literature.

Asterisks indicate studies of phylogenetic meaning in biology mass used to test for sexual dimorphism, and numbers in parentheses indicate the number of individuals. Tabla 1. Figure 1. Figura 1. Statistical analyses Initially, we analyzed the phylogenetic signal for both body mass and home range across the 19 felid species for which we found enough data.

Then, we tested the influence of body mass on home range size, controlling for phylogeny by using a phylogenetic generalized least squares analysis PGLS. The PGLS is a phylogenetic regression method in which the covariance among specimens as result of phylogeny is expressed in the regression error term Martins and Phylogenrtic ; Grafen biologg For these phylogenetic analyses, we reconstructed the phylogenic tree of the Felidae according to the most recent phylogeny by Li et al.

We used the mean home range size and mean body mass data available from Pantheria database. At the species level, phylogenetic meaning in biology analyzed the differences maening body mass and home range size between males and females using a paired ttest separately for each of the three species. We used paired t-tests because male and female individuals, that were compared, were present in the same local environments, and thus they were affecting each other not independent.

In order to test for differences in home range size of the three species in meanint to habitat, why watching sports is good for you applied a two-way Anova, including sex, habitat, and their interaction as predictor variables. We categorized the habitat data as 0 open habitat i. We did not include P. We used log-transformed variables in all analyses to meet the assumptions of parametric tests.

All analyses were conducted phylogenetic meaning in biology ing the R environment, version 3. Phylogenetic signal on home range size and body phylogenetic meaning in biology in felids We detected a weak and non-significant phylogenetic signal in both home range. The home range size increased according to the increase in body mass of Felidae Figure 2. Phylogenetic meaning in biology 2. Phylogenetic generalized least squares analysis between the home range log km 2 of felid species and their phylogenetic meaning in biology mass log g.

Figura 2. Effects of sex on body mass and home range size Males of the three species phylogenetic meaning in biology larger body mass than females P. Male home ranges are also larger than those of females for the three felid species P. Figure 3. Body mass of males and females phtlogenetic Panthera onca, Leopardus pardalis and Puma concolor. Boxplot indicates mean, standard deviation boxand maximum and minimum values vertical bar.

Data used to generate the boxplots were included without log transformation as a merely illustrative case, but the main analyses in the text were done with log-transformed data. Figura 3. Dimorfismo sexual entre especies. Phylogenetic meaning in biology 4. Home range sizes of males and females of Panthera onca, Leopardus pardalis and Puma concolor. Figura 4. Effects of habitat type on home range size The ANOVA revealed significant differences in the home range size between open and closed habitats for P.

Thus, the biologj range of this species is larger in open habitats than in closed habitats Figure 5. There was no difference in home range size between habitat types for L. Figure 5. Home range size of P. Data used to generate the boxplot were included without log transformation phylogenetic meaning in biology a merely illustrative case, but the main analyzes in the text were done with log-transformed data.

Figura 5. The home-range size of Felidae showed a adobe pdf filler free download correlation with body mass, and this causal relationship meaning in hindi true after accounting for phylogeny, meaning that other environmental e.

As expected, our results support the general pattern of positive association between home range size and body mass for terrestrial mammals Lindsted et al. This relationship between home range size and body mass may be a consequence of energetic requirements McNab ; Gittleman and Harvey Particularly, large-bodied animals need to increase their home ranges to access more resources to meet their metabolic rates and ensure their survival, especially during critical biological periods Lindsted et al.
