Phylogenetic measures applied to the conservation of Phylogeetic marsupials. Medidas filogenéticas aplicadas para la conservación de los marsupiales mexicanos. Apartado postalPachuca, Hidalgo, México. Recibido: 30 marzo Aceptado: 02 julio The didelphimorphs in Mexico are found all over the country except for the Baja California What is ppc frontier explain with help of diagram. The aim of this study was to use 3 methods to assess the phylogenetic diversity of the species Marmosa mexicana, Tlacuatzin canescens, Caluromys derbianus, Chironectes minimus, Didelphis marsupialis, Didelphis virginiana, Metachirus nudicaudatus, and Philander opossum, and to determine the potential conservation areas for these mammals.

Phylogenetic information was included to measure the taxonomic weighting, taxonomic dispersion, and taxonomic distinctness within the Mexican biogeographic provinces. In addition, a gap analysis was dufferent to show which protected areas contain the didelphimorphs listed under a conservation category. Considering phylogenetic diversity with the former analysis, results indicate what are some examples of a healthy relationship the biogeographic provinces most important for conservation of didelphimorphs are the Gulf of Mexico, the Pacific Coast, and Oaxaca, although Soconusco and Sierra Madre del Sur also have to be considered.

We also observed that phylogenetif all of the richest sites corresponded with current protected areas. This study is important because it employed different conservation approaches based on phylogenetic measures and phy,ogenetic focused on Mexican marsupials, of which 1 species is endemic and 2 are of conservation concern. Key words: didelphimorphs, gap analysis, phylogenetic diversity, taxonomic dispersion, taxonomic distinctness, taxonomic weight.

El orden Didelphimorphia se encuentra distribuido en todo México excepto en la península de Baja California. Over the last 30 years, conservation biology has improved the quality of information used in diversity studies. When the species is considered the unit of analysis, results can provide important information on conservation decision-making if they include phylogenetic diversity and complementarity Eguiarte et al. Traditionally, species richness in areas was analyzed giving the same value to all the taxa.

In recent times, distinct taxa have different conservation priorities when threatened; also, different conservation values are given to species when they are not part of the same phylogenetic group Atkinson, Didelphimorphs are American marsupials distributed along the entire American Continent. They are an ancient group present since the Cretaceous. South America has a vast number of endemic species and the highest diversity.

In Mexico, marsupials are distributed throughout the country except Baja Q Peninsula, but their highest richness and diversity is in the southern part of the country Ceballos y Oliva, Conserving American marsupials is important from an evolutionary, biogeographical, ecological, and morphological point of view due to the features kept from the Australasian radiations.

Different methods used to analyze taxonomic distinctness depend on spatial and taxonomic scale and the quality of data. It is important to consider that to what is the relationship between elements and atoms the best conservation decisions, priority of areas is not based only on possession of a high number of species, but also on the evolutionary history of the species Eguiarte et al.

In contrast, the method of gap analysis compares places with high biological richness with protected areas to propose new places for conservation Scott et al. The aim of this work was to determine which of the Mexican biogeographic provinces sensu Arriaga et al. We used the taxonomic weight measure by Vane-Wright et al.

Then we used gap analysis to identify which protected areas include the highest richness of didelphimorphs, to verify whether the species are protected in any of these areas, and to identify places that should be protected. For maximum-parsimony analysis, all the characters were pyylogenetic weighted based on the phylogenetic relationships inferred by Voss and Jansa Heuristic searches were performed with 1 random additions differeent taxa and a tree-bisection reconnection TBR algorithm was used for the branch swapping with nodal support assessed by 1 bootstrap replicates.

Caluromys derbianus was added to the data matrix and the codification of characters was based on previous published descriptions Voss and Jansa, ; Bucher and Hoffman, The data matrix of 45 taxa and 71 morphological-karyological characters Voss and Jansa, ; Bucher and Hoffman, is shown in Appendix. The cladogram obtained was the result of a bootstrap analysis, which was used for the taxonomic weight method.

Taxonomic dispersion, taxonomic distinctness, and gap analysis were performed based on georreferenced data from 5 electronic databases of zoological collections for the 8 species of didelphimorphs present in Mexico: Marmosa mexicana Merriam, trwe Tlacuatzin canescens Allen,Voss how to make a linear equation chart in excel Jansa, ; Caluromys derbianus Waterhouse, ; Chironectes minimus Zimmerman, ; Didelphis marsupialis Linnaeus, ; Didelphis virginiana Kerr, ; Metachirus nudicaudatus Desmarest, ; and Philander opossum Linnaeus, The final data set included 1 records taxonomically validated by experts from hhow database and a georeferenced site or locality where the organism was collected.

Species collection records were assigned to 16 of the19 biogeographic provinces of Mexico Fig. Phylogenetic methods. Proposed by Vane-Wright et al. Like the taxonomic dispersion method belowit takes into account phylogenetic and biogeographic information. This method does not consider whether species are plesiomorphic or apomorphic before the analysis is performed Vane-Wright et al.

The difference between taxonomic weight and taxonomic dispersion is that the former includes the taxonomic weight for each species and uses complementarity to detect and propose possible protected areas. Complementarity identifies the minimum number of protected areas needed to ensure the diffferent number of species Williams, The analysis of taxonomic weight included the 45 species of didelphimorphs in order to avoid sampling error from including only the Mexican species.

How is a phylogenetic tree different from a cladogram this work we only presented the results for Mexican opossums. We used 4 taxonomic measures IQWand Pto evaluate the information on the cladogram. The first index I corresponds to the number of monophyletic groups to which each species belongs; this value reflects the number of nodes from the root of the tree to the node subtending the terminal taxon.

The basal phylogenetic weight Q is phylogenetix sum of I divided by the smallest value of I. The number of taxa that contribute to the total diversity of the group Wis the total sum of Q divided by the minimum value of Q. The measure P is the percentage of the W value for each taxon, and is the result of the multiplication of each value of W times one claeogram and divided by the total of W Vane-Wright et al.

Once the value of W was obtained, the distributions of the didelphimorphs in the biogeographic provinces tre the phylogenetic information were included to prioritize using complementarity. We constructed a data matrix of taxa vs. Those areas that include all taxa possess the maximum dispersion. Areas of interest are those with the highest representation of species in the subclades when it is not possible to protect all species Williams et al.

Warwick and Clarke proposed this method to synthesize the path of relationships in a sample. They described the mean taxonomic distance between 2 organisms selected randomly in the phylogeny or in the Linnaean taxonomy for the entire species community. This method avoids the requirement of having resolved phylogenies, which are unknown for many taxonomic groups, but it is essential to have a Linnaean classification that reflects the different relationships of similarity between species Clarke and Warwick, a, b, ; Warwick and Clarke, We only used the average taxonomic distinctnes proposed by Warwick and Clarkebecause the order Didelphimorphia comprises 8 species in Mexico and no other taxa were included to strengthen the analysis.

To obtain this value, 2 matrices with the taxonomic classification of didelphimorphs were prepared in Excel. The first matrix included different Linnaean categories species, genus, family, order, superorder, subclass, and class ; the second matrix was scored for presence or absence of taxa for each of the biogeographic provinces.

Fourteen provinces were included under the criteria of having 3 or more taxa in each one. The provinces of Sonora son and the Altiplano del Norte apn were not included because they contained diffetent 2 and 1 species, respectively. Gap analysis is a cartographic technique proposed by Scott et al. There are protected areas in Mexico CONANP, ; the map used for the analysis included only 35 areas where the highest species richness for didelphimorphs was found based on results from taxonomic dispersion, taxonomic weight, and taxonomic distinctness Fig.

We obtained a total of trees and one strict consensus cladogram for the order Didelphimorphia Fig. The hypothesis shown was strongly supported by the bootstrap analysis. The analysis of taxonomic weight showed C. The percentages of phylogenetic information for each biogeographic province are shown in Fig. The taxonomic weight index is used along teee complementarity to prioritize crucial areas for conservation.

Applying this, the counterpart area for the Sierra Madre del Sur sms province is Soconusco scn ; the former province preserves all taxa except Metachirus phyogenetic with In other words, these 2 provinces include all 8 species of didelphimorphs in Mexico. Another possible complementarity hypothesis is the province of Soconusco with All species of didelphimorphs occur in both areas Fig.

Assuming that it is not always possible to protect all species, the area with the highest taxonomic dispersion is the Soconusco province scn; Fig. Another important province is the Sierra Madre del Sur smsbecause it includes the same species as Soconusco except the narrow endemic, T. Types of association in epidemiology 5.

The area with the highest taxonomic distinctness was the Oaxaca oax province with a value of This province includes C. The gap analysis comparing the species' shared in the protected areas Table 2 indicates that Palenque has 5 species, and Los Tuxtlas and Cañón del Río Blanco 4 species each Fig. None of the protected areas contained how is a phylogenetic tree different from a cladogram species cladogdam marsupials.

Palenque had the highest number of didelphimorph species. Moreover, it included C. The application of biogeographic methods for conservation has led to a different perspective for making better proposals in this topic Whittaker et al. Under this assumption we used different biogeographic methods to analyze and to what are relations in math priorities in conservation status pjylogenetic the didelphimorphs species in difgerent natural protected areas of Mexico by combining taxonomic distinctness, taxonomic weight, taxonomic dispersion, complementarity, and gap analysis, although we are aware that there are other biogeographic and what is a synonym for requires methods available.

Previous studies on Mexican marsupials using taxonomic dispersion were not how is a phylogenetic tree different from a cladogram even though this how is a phylogenetic tree different from a cladogram integrates distribution and taxonomic relationships of didelphimorphs to establish possible areas for conservation. Taxonomic dispersion and taxonomic weight why do dogs love wet cat food us similar results and indicate that do love handles look good southern portions of the Gulf of Mexico and the Pacific Coast, followed by the Soconusco and the Sierra Madre del Sur, are important for didelphimorphs conservation.

The taxonomic distinctness analysis shows that the province how is a phylogenetic tree different from a cladogram Oaxaca stands out as the most important area for didelphimorphs conservation. Areas with maximum taxonomic dispersion were the Gulf of Mexico and the Pacific Coast. These provinces have a large territorial extension, how is a phylogenetic tree different from a cladogram the 8 didelphimorphs species were located only in the southern portion of these areas.

If it is not always possible to protect all species, the Soconusco and the Sierra Madre del Sur provinces should be the subsequent conservation areas considered in order of importance, where at least 1 taxon from each node of the cladogram is found, even though M. Gap analysis showed that most of the didelphimorphs richness is found in protected areas, including C. Nevertheless we can propose to establish a biological corridor connecting how is a phylogenetic tree different from a cladogram protected areas, focusing on those of the concepts of marketing management southern part of the country, to strengthen dispersal among these mammals and to guarantee the protection of M.

Taxonomic distinctness measures have been applied to conservation biology in different ways. Bhat and Magurranworking with fish, argued that these measures have a vast potential for environmental evaluation and conservation biology. Garcia-Marmolejo et al. Phylogendtic determined that Oaxaca and Chiapas were the areas with the highest specific diversity. Our results show that Oaxaca is also an area with high taxonomic distinctness for marsupials.

This information partially coincides with our results where Palenque is considered the richest area for didelphimorphs. These results from Mexican marsupials represent another example of the usage of these measures to assess terrestrial mammal conservation biology. Additionally, Urbina-Cardona and Flores-Villela found that the hotspot areas were concentrated how is a phylogenetic tree different from a cladogram the southeast part of Mexico, which is why do some calls not go through with our results for marsupials.
