ZooKeys 417: 103-132. doi: 10.3897/zookeys.417.7551 Abstract The Chrysomelidae (Coleoptera) is a highly speciose family that has been poorly studied at the region- al level in Mexico. In the present study, we estimated species richness and diversity in oak-pine forest, Tamaulipan thorny scrub and in tropical deciduous forests in Peregrina Canyon within the Altas Cumbres Protected Area of the northeastern state of Tamaulipas, Mexico. Sampling of Chrysomelidae consisted of five sweep net samples (200 net sweeps) within each of three sites during four sample periods: early dry season, late dry season, early wet season, and late wet season. Species were identified and total numbers per species were recorded for each sample. A total of 2,226 specimens were collected belonging to six subfamilies, 81 genera and 157 species of Chrysomelidae from the study area. Galerucinae was the most abundant subfamily with 1,828 specimens, representing 82.1% of total abundance in the study area. Lower abundance was recorded in Cassidinae (8.5%), Eumolpinae (3.6%), Cryptocephalinae (2.2%), Chrysomelinae (2.2%), and finally Criocerinae (1.3%). The highest species richness was also presented in the subfamily Galerucinae with 49% of the total obtained species followed by Cassidinae (20%), Crypto- cephalinae (9.7%), Eumolpinae (9.7%), Chrysomelinae (6.5%) and Criocerinae (5.2%). The most com- mon species were Centralaphthona fulvipennis Jacoby (412 individuals), Centralaphthona diversa (Baly) (248), Margaridisa sp.1 (219), Acallepitrix sp.1 (134), Longitarsus sp.1 (104), Heterispa vinula (Erichson) (91), Epitrix sp.1 (84) and Chaetocnema sp.1 (72). Twenty-two species were doubletons (1.97% of total abundance) and 52 were singletons (2.33%). The estimated overall density value obtained was 0.0037 in- dividuals/m2. The greatest abundance and density of individuals were recorded at the lowest elevation site. However, alpha diversity increased with increasing altitude. Similarity values were less than 50% among Copyright U,. Sanchez-Reyes et al.

The highest abundance was obtained during the late dry season, whereas diversity indices were highest during the early wet season. The present work represents the first report of the altitudinal variation in richness, abundance, and diversity of Chrysomelidae in Mexico. These results highlight the importance of conservation of this heterogeneous habitat and establish baseline data for Chrysomelidae richness and diversity for the region. Keywords Chrysomelidae, leaf beetles, species richness, abundance, altitude, Northeast Mexico Introduction Chrysomelidae is one of the largest families within the order Coleoptera, with over 35,000 species described worldwide (Jolivet et al. 2009). In Mexico, about 2,174 spe- cies are known (Orddfez-Reséndiz et al. 2014), although the actual number is prob- ably considerably greater. The family is also an economically important group due to their predominantly phytophagous feeding habits (Ding et al. 2007, Meissle et al. 2009). This feeding characteristic and their generally high abundance also make leaf beetles an important component of food webs and a major component of tropical her- bivore guilds (Farrell and Erwin 1988, Basset and Samuelson 1996) as well as being an important food item for other organisms (Eben and Barbercheck 1996). The great species richness of Chrysomelidae and their role as a phytophagous func- tional group make the Chrysomelidae a potentially useful indicator group for: 1) bio- diversity of a region (Farrell and Erwin 1988, Kalaichelvan and Verma 2005, Baselga and Novoa 2007, Aslan and Ayvaz 2009), 2) environmental quality (Linzmeier et al. 2006), and 3) as a taxon for monitoring changes in natural areas (Staines and Staines 2001, Flowers and Hanson 2003). However, the use of this family as such has not been adequately explored. In addition, the general lack of published studies of the species richness and diversity of Chrysomelidae in Mexico (Burgos-Solorio and Anaya-Rosales 2004, Andrews and Gilbert 2005, Nifo et al. 2005, Furth 2006, Furth 2009), makes it dificult to compare the particular ecological characteristics and biogeographical dis- tribution patterns of this family with other taxa in the country. Recent climatic and environmental changes create an ecological imbalance that threatens biodiversity. It is vital that baseline data is available through faunistic inven- tories along elevational gradients to record and predict how organisms alter distribu- tions and adapt to environmental changes (Maveety et al. 2011). This is especially so for Mexico where altitude is often associated with marked changes in the richness and abundance of species (Peterson et al. 1993), producing rapidly changing distribution patterns along altitudinal gradients (Hodkinson 2005). The present study was conducted in the Cafion of the Peregrina within Altas Cum- bres Protected Area (Vargas et al. 2001) within the northeastern state of Tamaulipas, Mexico. This protected area is located in one of the 15 panbiogeographic nodes in the country. These nodes have unique characteristics which make them centers of higher species richness with high conservation priority (Morrone and Marquez 2008) making Diversity and altitudinal distribution of Chrysomelidae (Coleoptera) in Peregrina Canyon... 105 the study area an excellent site for analysis of biodiversity and altitudinal distribution of Chrysomelidae in northern Mexico. The objectives of the present study were: 1) determine the species richness of Chrysomelidae in Peregrina Canyon, Tamaulipas, Mexico; 2) conduct the first site- specific evaluation of diversity for this taxon in northeast Mexico; and 3) analyze the variation of species richness, abundance and diversity of the family along an altitudinal gradient during different seasons within the study area. Methods Study area The Peregrina Canyon (Canyon San Felipe or Liberty), is located in the northwest portion of municipality of Victoria, Tamaulipas, along the San Felipe River (Figure 1). The area is located in the Sierra Madre Oriental and is part of Altas Cumbres Protected Area, considered a Special Zone subject to Ecological Conservation established by state decree in 1997 (Vargas et al. 2001). The study area belongs to one of the 15 panbio- geographic nodes present in the country due to the overlap of three biotic provinces: Tamaulipas, Sierra Madre Oriental, and Mexican Gulf (Morrone and Marquez 2008). The altitude within the study area ranges from 340 to 1600 m. ‘The climate of the region is warm and subhumid with summer rains; the mean annual temperature is 18 to 24.3 °C and the mean total annual rainfall is 717.3 mm to 1058.8 mm (Almaguer- Sierra 2005). Site location Three sites were established within which five quadrants of 2500 m* (50x50 m) were delineated in representative vegetation at each site. Site 1 had the lowest elevation at 340 m and consisted of low tropical semideciduous forest (23°45.30'N; 99°18.39'W). Site 2 was located at an intermediate altitude at 550 m where the plant communi- ty consisted of Tamaulipan thorny scrub (23°46.32'N; 99°14.96'W). Site 3 was the highest site at 1100 m with the vegetation composed of oak-pine forest (23°46.62'N; 99°12.55'W). Collection and processing of specimens Sampling was conducted using a standard entomological sweep net of 40 cm diam- eter. Individual samples consisted of 200 sweeps of the shrub and herbaceous vegeta- tion in each quadrant. ‘The contents of the net were emptied into a 2000 cm’ plastic bag, adding 60% ethanol and an indelible label with corresponding data.

Location of Peregrina Canyon in Tamaulipas, Mexico, and location of sampling sites along study area. were collected at each site from 10:00 to 14:00 hrs. Five samples (one sample for each quadrant, 200 net sweeps) were taken within each of three sites (one site per day), at four different dates in each of the four seasons of the year (early dry season, Diversity and altitudinal distribution of Chrysomelidae (Coleoptera) in Peregrina Canyon... 107 EDR, December-February; late dry season, LDS, March-May; early wet season, EWS, June-August; and late wet season, LWS, September-November) between January and December 2009, for a total of 240 samples. Processing of the samples was performed in the laboratory in the following man- ner. First, the contents of each plastic bag (sample) were placed in a plastic tray with water, and the more voluminous plant remains (wood fragments, branches, stems, leaves) were removed. A sieve ALSA (0.175 mm) was then used to filter the sample, and the reduced contents placed in a petri dish and observed under a stereoscopic mi- croscope for extraction of all chrysomelid beetles. These were separated and mounted on paper points according to standard entomological technique. All specimens are stored in the collection of the Facultad de Ingenieria y Ciencias at the Universidad Autoénoma de Tamaulipas, Ciudad Victoria, Tamaulipas, Mexico. Taxonomic determination The identification of the specimens was performed using the available literature on Chrysomelidae (Wilcox 1965, White 1968, Wilcox 1972, Scherer 1983, White 1993, Flowers 1996, Riley et al. 2002, Staines 2002). Where possible, the material was com- pared with identified specimens deposited in the collection of Chrysomelidae of the Facultad de Ingenieria y Ciencias, Universidad Autonoma de Tamaulipas. Those speci- mens that could not be identified to the species level were compared with other uni- dentified specimens and grouped into morphospecies. The designation of “species” in this study includes both morphospecies and determined species. The classification used in this work corresponds to latest taxonomic categories proposed by Riley et al. (2003), except for the subfamily Bruchinae not included in this study. Data analysis Abundance was calculated using the number of individuals per species collected at each site, season and for the entire study area. Species abundance was divided into five categories: 1) very common (more than 70 individuals); 2) common (11 to 70); 3) rare (10 to three specimens); 4) doubletons (two specimens); and 5) singletons (one speci- men only). As a measure of species richness, we used the number of species present throughout the Peregrina Canyon, in each of the three altitudinal strata analyzed, and in each season. To estimate the potential number of species (total, site, and season), the nonparametric estimators Chao 1 and Jackknife 1 were used. These estimators were chosen because: 1) we did not assume a previous abundance distribution model, 2) they are robust when calculating minimum estimate of species richness, 3) their use is recommended as a recurrent measure in analysis of biodiversity, 4) Chao 1 is based on abundance data, or singletons and doubletons, and Jackknife 1 (incidence) is based on uniques, or species found in only one sample (Magurran 2004, Hortal et 108 Uriel Jeshua Sdnchez-Reyes et al. / ZooKeys 417: 103-132 (2014) al. 2006, Gotelli and Colwell 2010), and 5) Jackknife indices tend to be conservative estimators, so the use of both Chao 1 and Jackknife 1 can give an estimated range of species richness (Silva and Coddington 1996). The estimators were calculated with 100 randomizations without replacement using the software EstimateS 8.2 (Colwell 2009) based on the number and abundance of species found per sampling unit (quadrant). Sampling efficiency was also measured by using Clench model, through the coefh- cient of determination (R’) and the slope of the species accumulation curve, which measures the inventory quality. Their calculation was based on the number of samples (quadrants) in the entire study area, site and season; the procedure was performed in the program STATISTICA 8.0 (StatSoft Inc. 2007) based on the method described by Jiménez-Valverde and Hortal (2003). We also calculated overall density, or number of chrysomelid beetles per square meter for future comparisons and was calculated for the entire study area and for each site and season. After testing for normality of the data, we used the nonparametric Kruskall Wallis and Mann-Whitney tests to analyze the differences in abundance and number of spe- cies among the three sites and between different seasons (PAST version 1.94b, Ham- mer et al. 2001) using as independent variables the total number of specimens and species per sample unit (quadrant). Alpha diversity for the whole study area and by site and season was calculated using the Simpson diversity index (1/D) and the Shannon diversity index (H °) (Magurran 2004), using EstimateS 8.2. Differences of diversity values between sites and seasons were analyzed using PAST version 1.94b (Hammer et al. 2001). SHE analysis of diversity was conducted to decompose the Shannon diversity value in a measure of species richness and evenness, to allow the interpretation of changes in diversity (Magurran 2004). As a beta diversity measure, Bray-Curtis similarity index (Sorensen’s quantitative index; Magurran 2004) was used among the sites and seasons, using EstimateS 8.2; these data were used to build a distance matrix for an agglomerative cluster analysis, using the Ward’s method as amalgamation algorithm calculated using STATISTICA 8.0. A Spearman correlation test was applied between precipitation and temperature data with ecological parameters (abundance and species richness) using STATISTICA 8.0. Precipitation and temperature data were obtained from a local meteorological station localized in Peregrina Canyon. Results Abundance, richness and diversity of Chrysomelidae in Peregrina Canyon A total of 2,226 specimens of Chrysomelidae were collected from 240 samples from May 2009 to April 2010, belonging to six subfamilies, 81 genera and 157 species (Table 1). Galerucinae was the most abundant subfamily with 1,828 specimens, rep- resenting 82.1% of total abundance in the study area. Lower abundance was recorded in Cassidinae (8.5%), Eumolpinae (3.6%), Cryptocephalinae (2.2%), Chrysomelinae (2.2%), and finally Criocerinae (1.3%).

Eight species were categorized as “very common” in the Peregrina Canyon, each with greater than 70 specimens and accounted for 61.22% of the total abundance. These very common species were Centralaphthona fulvipennis Jacoby (412 individuals), Centralaphthona diversa (Baly) (248), Margaridisa sp.1 (219), Acallepitrix sp.1 (134), Longitarsus sp.1 (104), Heterispa vinula (Erichson) (91), Epitrix sp.1 (84) and Chaetoc- nema sp.1 (72). Twenty-five species were considered common, constituting 22.66% of the total number of chrysomelids. Fifty species were considered rare (263 specimens) by occupying 11.8% of the total abundance. Twenty-two species were doubletons (1.97% of total abundance) and 52 were singletons (2.33%). The estimated density value obtained was 0.0037 individuals/m?

The richness estimators indicated that the total number of chrysomelid species in the study area was between 216 and 218 species (Table 2, Figure 2) suggesting that the observed total of 157 species represented 71.86 to 72.43% of the actual richness. The data showed a good fit to the Clench model (R’ = 0.99), with a registered proportion of species of 73.91% and a slope close to 0.1. Total diversity values of Chrysomelidae in Peregrina Canyon were 14.58 for the Simpson index and 3.53 for the Shannon index (Table 2). The SHE analysis shows that changes in Shannon diversity value are attributed to increase and stability of species richness curve (Figure 3). Altitudinal variation of Chrysomelidae The abundance of chrysomelid beetles was significantly different among the three sites (Table 2). The greatest abundance and density (individuals per square meter) were re- corded at the lowest elevation site, and decreased with increasing altitude (Table 2). The middle altitude site (Site 2) had the greatest number of species (Table 2).

In the low altitude site, 85 species were recorded which rep- resented between 67.2 to 71.35% of the estimated richness (minimum and maximum) 116 Uriel Jeshua Sdanchez-Reyes et al. / ZooKeys 417: 103-132 (2014) | Total Peregrina Canyon 4.81 Site 1, Low tropical semideciduous forest 340 m Diversity Diversity 250 500 750 1000 1250 1500 1750 2000 120 240 360 480 600 720 840 960 1080 N N Site 3, Oak pine forest, 1100 m scrub, 550 m Diversity 80 160 240 320 400 480 560 640 50 100 150 200 250 300 350 400 450 N N Figure 3.

In the second site, the number increased to 96 species (48.96 to 63.86% of the estimate) and at the highest site, 84 species were recorded (59.62 to 68.01% of the estimate) (Figure 2). A determination coefficient greater than 0.99 was obtained for all sites, indicating a good fit of the Clench model to the data obtained at each site, but the slope calculated was greater than 0.1 in all sites (Table 2). Alpha diversity at the three sites differed significantly (p < 0.05) with indices increasing progressively with increasing altitude (Table 2). Lower diversity values in both sites 1 and 2, were a result of a reduction in eveness and a more or less stable number of species with the increase of samples. In site 3, diversity increases as eveness remained constant and the number of species increased with sample numbers (Figure 3). Of the 157 species recorded in the Peregrina Canyon, 34 were distributed along the entire altitudinal gradient, 40 were recorded only in two sites, and 83 were unique to one of the three sites. Of these, 29 were exclusively from Site 1, 34 for Site 2, and 20 for Site 3 (Table 1). Similarity values were in all cases less than 50%; according to the cluster analysis, each of the three sites was an independent group, containing distinct species assemblages of Chrysomelidae (Figure 4).

Cluster analysis from sites in the Peregrina Canyon, Tamaulipas, Mexico. Seasonal variation of Chrysomelidae General abundance of Chrysomelidae was greater in the dry season than the wet sea- son. Late wet season was not significantly different from early dry and wet seasons; the rest of comparisons between seasons were significantly different. The highest abun- dance was obtained during the late dry season, with 822 individuals. Fewer individu- als were found during the early dry season (696 specimens), and late and early wet seasons, 406 and 302, respectively. Density for seasons followed the same pattern as the abundance, being late dry season the period with higher densities of chrysomelid beetles (Table 2). The number of species collected per season declined as the year pro- gresses. During late dry season, 96 species were recorded, representing between 69.91 and 72.72% of the estimated richness for that season; 84 species were found in early wet season (62.36 to 64.5% of estimated richness), while the number decreases to 56 species in late wet season (66.25 to 66.34%) and 43 species in early dry season (77.08 to 87.66%) (Table 2; Figure 5). Determination coefficients based on the Clench model was higher than 0.99 for all seasons, while the slope values were above 0.1 (Table 2). Higher temperatures and precipitation were found within both wet seasons (Figure 6). High correlation values were present between temperature and richness, and between precipitation and abundance. Abundance was negatively correlated with precipitation, while species richness was positively correlated with maximum temperature. Other comparisons were not significant (Table 3). In contrast to abundance, the Shannon and Simpson indices indicated the highest diversity during the early wet season. Lower values of diversity occurred in late dry sea- 118 Uriel Jeshua Sanchez-Reyes et al. / ZooKeys 417: 103-132 (2014) 140 —_—___—_— WET SEASON 120 100 tars eooree oo-gee lo Oe esti ae goa 80 ate, e ee eh OO Pr etal es ciate Bo er aon On 60 Species richness 40 20 —- Sobs -e- Chao 1 -+- Jack 1 1 #4 7 10 13 16 19 22 25 28 31 34 37 40 43 46 49 52 55 58 61 DRY SEASON 140 120 100 80 60 ahh me dndee id ot Adee & and Cc eteeetnowrs ses © 0 00-00 6 © o 0-06-60 6 0-68 soa” Ane Species richness 40 20 --- Jack 1 1 4 7 10 13 16 19 22 25 28 31 34 37 40 43 46 49 52 55 58 61 Samples Figure 5.

Based on diversity indices, all seasons were statistically different (p < 0.05) (Table 2).
