“…Second, although the most commonly documented response of plants to climate change were distributional range shifts to higher latitudes and/or elevations ( Parmesan and Yohe, 2003 ; Zhang et al, 2018 ), it was also necessary to predict how various developmental models would determine the spatial extent of their suitable habitat. Third, the ecological niche overlaps between species with close relationships might produce habitat competition to some extent ( Eyres et al, 2020 ), and thus predicting the spatial distribution of various Fritillaria species might find species-specific habitat to decrease competition. Fourth, the distribution of a species is an expression of its evolutionary history and its ecology ( Soberón and Peterson, 2005 ; Villegas et al, 2021 ).…”

Fritillaria species, a well-known Chinese traditional medicine for more than 2,000 years, have become rare resources due to excessive harvesting. In order to balance the economical requirement and ecological protection of Fritillaria species, it is necessary to determine (1) the important environmental variables that were responsible for the spatial distribution, (2) distribution change in response to climate change in the future, (3) ecological niche overlap between various Fritillaria species, and (4) the correlation between spatial distribution and phylogenies as well. In this study, the areas with potential ecological suitability for Fritillaria cirrhosa, Fritillaria unibracteata, and Fritillaria przewalskii were predicted using MaxEnt based on the current occurrence records and bioclimatic variables. The result indicated that precipitation and elevation were the most important environmental variables for the three species. Moreover, the current suitable habitats of F. cirrhosa, F. unibracteata, and F. przewalskii encompassed 681,951, 481,607, and 349,199 km2, respectively. Under the scenario of the highest concentration of greenhouse gas emission (SSP585), the whole suitable habitats of F. cirrhosa and F. przewalskii reach the maximum from 2021 to 2100, while those of F. unibracteata reach the maximum from 2021 to 2100 under the scenario of moderate emission (SSP370) from 2021 to 2100. The MaxEnt data were also used to predict the ecological niche overlap, and thus high overlap occurring among three Fritillaria species was observed. The niche overlap of three Fritillaria species was related to the phylogenetic analysis despite the non-significance (P > 0.05), indicating that spatial distribution was one of the factors that contributed to the speciation diversification. Additionally, we predicted species-specific habitats to decrease habitat competition. Overall, the information obtained in this study provided new insight into the potential distribution and ecological niche of three species for the conservation and management in the future.

“…Here, we make use of a newly compiled dataset of extent‐of‐occurrence range maps that comprised both the breeding and nonbreeding ranges of bird species (Eyres et al. 2020). Despite limitations for climatic niche quantification (Graham and Hijmans 2006), such maps represent the most consistent coverage of a species range that are currently available at a global scale across large numbers of species (Kearney et al.…”

“…2017), we made use of a new database of nonbreeding ranges of migratory bird species (GeoMiB; see Eyres et al. 2020 and Supporting Information for details) to ensure that our niche quantifications take into account the climatic conditions experienced by species in their breeding and nonbreeding range (Eyres et al. 2017).…”

Climatic effects on niche evolution in a passerine bird clade depend on paleoclimate reconstruction method

Climatic niches describe the climatic conditions in which species can persist. Shifts in climatic niches have been observed to coincide with major climatic change, suggesting that species adapt to new conditions. We test the relationship between rates of climatic niche evolution and paleoclimatic conditions through time for 65 Old‐World flycatcher species (Aves: Muscicapidae). We combine niche quantification for all species with dated phylogenies to infer past changes in the rates of niche evolution for temperature and precipitation niches. Paleoclimatic conditions were inferred independently using two datasets: a paleoelevation reconstruction and the mammal fossil record. We find changes in climatic niches through time, but no or weak support for a relationship between niche evolution rates and rates of paleoclimatic change for both temperature and precipitation niche and for both reconstruction methods. In contrast, the inferred relationship between climatic conditions and niche evolution rates depends on paleoclimatic reconstruction method: rates of temperature niche evolution are significantly negatively related to absolute temperatures inferred using the paleoelevation model but not those reconstructed from the fossil record. We suggest that paleoclimatic change might be a weak driver of climatic niche evolution in birds and highlight the need for greater integration of different paleoclimate reconstructions.

“…Fourth, the changing environmental conditions experienced by parasites over the long‐distance migration of their hosts should select for increased tolerance and the ability to survive and/or transmit under a wider range of abiotic conditions. There are exceptions: in some migratory species, niche tracking allows migrants to experience lower climatic variation than residents (Eyres et al ., 2020), which could provide stable environmental conditions for their parasites. In most cases, however, long‐distance host migration is associated with changes in environmental conditions.…”

Migrations, i.e. the recurring, roundtrip movement of animals between distant and distinct habitats, occur among diverse metazoan taxa. Although traditionally linked to avoidance of food shortages, predators or harsh abiotic conditions, there is increasing evidence that parasites may have played a role in the evolution of migration. On the one hand, selective pressures from parasites can favour migratory strategies that allow either avoidance of infections or recovery from them. On the other hand, infected animals incur physiological costs that may limit their migratory abilities, affecting their speed, the timing of their departure or arrival, and/or their condition upon reaching their destination. During migration, reduced immunocompetence as well as exposure to different external conditions and parasite infective stages can influence infection dynamics. Here, we first explore whether parasites represent extra costs for their hosts during migration. We then review how infection dynamics and infection risk are affected by host migration, thereby considering parasites as both causes and consequences of migration. We also evaluate the comparative evidence testing the hypothesis that migratory species harbour a richer parasite fauna than their closest free‐living relatives, finding general support for the hypothesis. Then we consider the implications of host migratory behaviour for parasite ecology and evolution, which have received much less attention. Parasites of migratory hosts may achieve much greater spatial dispersal than those of non‐migratory hosts, expanding their geographical range, and providing more opportunities for host‐switching. Exploiting migratory hosts also exerts pressures on the parasite to adapt its phenology and life‐cycle duration, including the timing of major developmental, reproduction and transmission events. Natural selection may even favour parasites that manipulate their host's migratory strategy in ways that can enhance parasite transmission. Finally, we propose a simple integrated framework based on eco‐evolutionary feedbacks to consider the reciprocal selection pressures acting on migratory hosts and their parasites. Host migratory strategies and parasite traits evolve in tandem, each acting on the other along two‐way causal paths and feedback loops. Their likely adjustments to predicted climate change will be understood best from this coevolutionary perspective.
