“…ese birds travel for a long distance from wintering to breeding grounds and any failure in nesting habitats would disturb whole life cycles. Consequently, the selection of nest location is considered the main adaptive response to a combination of climatic conditions [8,9], nest predation pressure [10][11][12], and human disturbances [13,14]. Its selection is therefore vital for individual fitness.…”

Investigations of niche splitting in the European turtle dove (Streptopelia turtur) have primarily addressed feeding habitats and foraging features and been limited to conspecific species, counting laughing dove and wood pigeon. The recent degradation of natural and suitable habitats for turtle doves, particularly in North Africa, would push this species to refuge in wetlands with a variety of other bird species. The understanding of potential cohabitation between doves and other species in these less disturbed ecosystems would help in the conservation measures of this declining game. This study, conducted from early March to September between 2015 and 2017, attempted to determine which species cohabit with turtle doves in three Northwest African wetlands in Morocco and how these species select nesting sites and trees. We used detrended corresponding analysis (DCA) to test the relevance of nest site and nesting tree variables in the nest distribution of the breeding species. The obtained results show a wide sharing of nest-niche between turtle doves and 7 breeding species, especially at the intermediate zone and downstream of the rivers. The lack of competition for food resources with neighbouring species may help in this harmonious sharing of both nesting sites and nesting trees. We further suggest guidelines for future research that seek to understand the spatiotemporal dynamics of species coexisting with turtle dove in the same habitats.

“…A growing number of studies are showing that niche breadth can impact multiple population and species parameters (Gómez-Rodríguez et al 2015, Saupe et al 2015, Qiao et al 2016, Ralston et al 2016, Rolland and Salamin 2016. However, it is also evident that a complex structure of environmental data, such as autocorrelation, makes it challenging testing the hypotheses on relationships between niche breadth and species distributions.…”

Microhabitat analyses support relationships between niche breadth and range size when spatial autocorrelation is strong

Multiple evidence of positive relationships between nice breadth and range size (NB-RS) suggested that this can be a general ecological pattern. However, correlations between niche breadth and range size can emerge as a by-product of strong spatial structure of environmental variables. This can be problematic because niche breadth is often assessed using broad-scale macroclimatic variables, which suffer heavy spatial autocorrelation. Microhabitat measurements provide accurate information on species tolerance, and show limited autocorrelation. The aim of this study was to combine macroclimate and microhabitat data to assess NB-RS relationships in European plethodontid salamanders (Hydromantes), and to test whether microhabitat variables with weak autocorrelation can provide less biased NB-RS estimates across species. To measure macroclimatic niche, we gathered comprehensive information on the distribution of all Hydromantes species, and combined them with broad-scale climatic layers. To measure microhabitat, we recorded salamander occurrence across > 350 caves and measured microhabitat features influencing their distribution: humidity, temperature and light. We assessed NB-RS relationships through phylogenetic regression; spatial null-models were used to test whether the observed relationships are a by-product of autocorrelation. We observed positive relationships between niche breadth and range size at both the macro-and microhabitat scale. At the macroclimatic scale, strong autocorrelation heavily inflated the possibility to observe positive NB-RS. Spatial autocorrelation was weaker for microhabitat variables. At the microhabitat level, the observed NB-RS was not a by-product of spatial structure of variables. Our study shows that heavy autocorrelation of variables artificially increases the possibility to detect positive relationships between bioclimatic niche and range size, while fine-scale data of microhabitat provide more direct measure of conditions selected by ectotherms, and enable less biased measures of niche breadth. Combining analyses performed at multiple scales and datasets with different spatial structure provides more complete niche information and effectively tests the generality of niche breadth-range size relationships.

“…Furthermore, biotic factors can strongly influence local species distributions (Jablonski, ), and some studies have shown macroecological signals of such species interactions (Gotelli, Graves, & Rahbek, ). Further research may integrate biotic factors including species interactions such as competition (Mordecai, Jaramillo, Ashford, Hechinger, & Lafferty, ), specialization (Fjeldså & Lovett, ), population and community dynamics (Locey & Lennon, ; Ralston, DeLuca, Feldman, & King, ), distributional shifts (Knowles & Massatti, ) and niche differentiation (Brown et al, ). A key question is whether and how such factors contribute to the origins and maintenance of species endemism in some areas and not in others that share similar environmental characteristics.…”

Aim We test macroecological hypotheses (H1: long‐term climate stability; H2: climate seasonality; H3: climate distinctiveness or rarity; and, H4: spatial heterogeneity in contemporary climate, topography or habitat) proposed to explain broad‐scale patterns of total species endemism. Location Continental areas worldwide and zoogeographical realms. Methods Using species distribution maps for mammals and amphibians, we calculated five metrics of species endemism, based on inverse and median range size, and range size cut‐offs. We performed multi‐model averaging. We tested the accuracy of fitted models using cross‐validation, comparing observed versus predicted values of endemism among zoogeographical realms. Results Model averaging showed that species endemism for amphibians and mammals was statistically related to all set of predictors (H1, H2, H4 and richness), except for climate distinctiveness (H3). Effect sizes for spatial heterogeneity were larger and more consistent among zoogeographical realms than the effect sizes of climate stability. The effect of species richness on species endemism varies widely and depends on the metric of endemism and taxonomic group used in the analysis. Cross‐validation across all zoogeographical realms showed that predictions of endemism systematically fail for both taxa. In most cases, low to moderate endemism is predicted reasonably well. However, areas with high numbers of endemic species are systematically under‐predicted. Main conclusions Our results are not consistent with any of the processes hypothesized to create and maintain global patterns of endemism. Although we found statistically significant relationships, they failed the stronger test of a causal relationship: accurate prediction in independent data. The inconsistent effect of richness in our models suggests that patterns of endemism are not driven by the same variables as total richness. Patterns of endemism have no consistent relationships with climatic stability among zoogeographical realms, so suggestions that endemism reflect climatic stability are likely due to collinearity with other factors, especially spatial heterogeneity.
