“…More empirical studies are needed on forbs and annual species as trees are over-represented in most population genetic studies ( Rico 2019 ; González et al 2020 ). Lastly, to further understand the conditions under which FSGS may occur or not in human-modified landscapes, more research is required on plant population dynamics, including investigating the microhabitat conditions that promote seedling establishment and growth, as well as the variance in reproductive success.…”

Do habitat fragmentation and degradation influence the strength of fine-scale spatial genetic structure in plants? A global meta-analysis

As primarily sessile organisms, plants often show a non-random spatial distribution of genotypes over distance. This process known as fine-scale spatial genetic structure (FSGS) has been suggested through systematic reviews to depend on life-form, mating system, and pollen and seed dispersal vectors, while there is no consensus on its behavior due to external factors, such as anthropogenic habitat changes. By conducting a systematic review and global meta-analysis of empirical FSGS studies, we aimed to evaluate how anthropogenic habitat fragmentation and degradation influence the strength of FSGS in plant populations by means of the Sp statistic. Moreover, we tested how pollination and seed dispersal vectors contribute to the variation of the Sp statistic. We retrieved 243 FSGS studies from 1960 to 2020 of which only 65 were informative for the systematic review. Most empirical studies comprised outcrossers (84%) and trees (67%), with few herbs (23%), and scarce annual species (2%). In weighted meta-analyses for 116 plant populations (31 studies), we did not detect significant effects in the magnitude of effect sizes for the Sp statistic among undisturbed, degraded, and fragmented habitats. Results showed significant effects for seed dispersal vectors, but not for pollination. Overall, we observed high variation among the effect sizes (not related to the goodness-of-fit of mixed models) of habitat status, pollination, and seed dispersal categories, which precludes identifying biological trends on the Sp statistic. More empirical studies are needed that contrast multiple plant populations in disturbed vs. undisturbed habitats, and by increasing the taxonomic groups, such as herbs and annual plants.

“…Although studies about genetics of the mammals of Mexico have been previously evaluated (Vázquez-Domínguez and Vega 2006), such assessment has not been done for landscape genetics. In this regard, it is important to mention that Rico (2019) recently published a review of landscape genetics studies conducted in Mexico to 2017, including 20 studies, with plants as the most studied taxonomic group (65%), while only two studies focused on mammals. This finding is consistent with our results, since we identified three studies for Mexico, two on rodents; of these, only one was conducted in a desert area.…”

“…We used the Web of Science website (http:// apps.webofknowledge.com) based on different combinations of terms as keywords: 'landscape genetics' , 'functional connectivity ' and 'mammals'; 'landscape genetics' , 'mammals' and 'desert'; 'landscape genetics' , 'mammals' , 'desert' and 'America'; 'functional connectivity' , 'mammals' and 'desert' . This literature search method has proved to be efficient in different review works (e. g., Storfer et al 2010;Dyer 2015;Rico 2019), which also allows a systematic and repeatable analysis, although it certainly may exclude some works.…”

Since the term was coined in 2003, landscape genetics (LG) is a field that integrates population genetics, landscape ecology, and spatial analytical techniques to quantify the effects of landscape on microevolutionary processes. Despite the growing interest in LG, there is little knowledge about the trends in LG research for America in general and regarding mammals in particular, as well as about which ecosystems are being most studied. Deserts represent nearly one-third of the Earth's surface and are characterized by high heterogeneity and species richness. However, they are underrepresented in the LG literature. Hence, we performed a thorough review of published scientific articles addressing LG of mammals in America, with emphasis on deserts. The objectives were to 1) determine the mammal groups that have been most studied; 2) establish the representation of desert ecosystems; 3) describe the research questions and analytical methods most frequently used; and 4) summarize the key landscape factors and environmental variables associated with genetic diversity and structure patterns of mammals in America. We conducted a comprehensive literature search of published articles between 2003 and 2019 in the Web of Science (http://apps. webofknowledge.com) based on search words specific to the revision subject. We verified and screened the articles recovered, and gathered basic information (species, authors, publication year), together with the research questions addressed and the genetic and statistical methods used. We recovered 36 publications on LG involving mammals in America; of these, only eight were conducted on desert ecosystems (Table 1). Rodentia was the most represented order in all American ecosystems (n = 20), while Artiodactyla (n = 4) was specifically represented in deserts. Of all studies, the most common research questions focused on estimating 'connectivity' (n = 14) and 'genetic structure' (n = 12), and the most frequent analytical methods were Mantel and partial Mantel tests. Dispersal capabilities and vegetation cover were the most important variables regarding the genetic structure of desert populations. Most studies evaluated connectivity with simple and partial Mantel tests, but the use of novel methodologies (i. e., genomics) was also identified. Ecological traits of species, particularly for rodents, and vegetation cover were the main factors related to genetic patterns in deserts. Notably, we identified that North America is the most studied region, while LG studies with mammals are scarce in Mexico and South America (one study encompassed North and Central America), as well as in desert ecosystems, hence the urgency to conduct studies in those regions and in deserts. La genética del paisaje (GP) integra conceptos y herramientas de la genética de poblaciones, ecología del paisaje y estadística espacial, para cuantificar los efectos de la matriz del paisaje en los procesos microevolutivos. Los ecosistemas de desierto están caracterizados por una alta heterogeneidad y riqueza de especies; sin ...
