Abstract

La especie Pleurozia paradoxa es una hepática de hábitat generalmente paramuno que se encuentra en estado vulnerable según el libro rojo de briófitas de Colombia debido a su poca presencia y su minúscula área de ocupación en el país. Mediante la aplicación de modelos de distribución de especies podemos estimar áreas de idoneidad que dan cuenta de la presencia probable de una especie. En este caso se usó un algoritmo de aprendizaje de máquinas denominado máxima entropía y el software Maxent, con el fin de obtener mapas de distribución potencial. Se emplearon varios registros de presencia y distintos juegos de variables climáticas para el modelamiento, además de un umbral de maximización de la especificidad y sensibilidad en el mapeo. Como resultado, la distribución potencial de P. paradoxa en Colombia se concentró en los departamentos del Cauca, Huila y Nariño a lo largo de la cordillera Central, extendiéndose levemente hacia el Valle del Cauca y Tolima, y en marcada relación con la altitud y el clima de dichas zonas.

Woodland-specialist epiphytic bryophytes are both a threatened ecological guild of forest species as well as a precise bioindicator of conservation value of forest ecosystems. However, due to lack of data on distribution, there is no information about their potential reaction to predicted climate change. For that reason we aimed to evaluate impact of climate change and forest continuity on distributions of an umbrella species of woodland-specialist epiphytic bryophytes. We compiled available data on Dicranum viride distributions in Europe, as this species is a subject of Natura 2000 conservation. We provided a species distribution model (developed using MaxEnt) using bioclimatic variables and a forest continuity map for Europe. We evaluated predicted changes in potential distribution for 2061–2080 using three climate change scenarios. We also assessed substratum preferences of this species. Our study revealed that forest continuity is the most important predictor of D. viride occurrence, and next were mean temperature of the driest quarter and precipitation in the warmest quarter. Projected climate change would lead to small losses of D. viride habitat suitability in Southern and Western Europe and increases in Scandinavia, under the assumption of constant forest continuity. Due to limited dispersal capabilities and specific habitat requirements, forest continuity and suitable forest assemblages/vegetation types play a superior role in maintaining woodland-specialist epiphytic bryophytes. For that reason loss of mature forest ecosystems is a more important threat to epiphytic bryophytes than climate change.

Ecological niche models are widely used in ecology and biogeography. Maxent is one of the most frequently used niche modeling tools, and many studies have aimed to optimize its performance. However, scholars have conflicting views on the treatment of predictor collinearity in Maxent modeling. Despite this lack of consensus, quantitative examinations of the effects of collinearity on Maxent modeling, especially in model transfer scenarios, are lacking. To address this knowledge gap, here we quantify the effects of collinearity under different scenarios of Maxent model training and projection. We separately examine the effects of predictor collinearity, collinearity shifts between training and testing data, and environmental novelty on model performance. We demonstrate that excluding highly correlated predictor variables does not significantly influence model performance. However, we find that collinearity shift and environmental novelty have significant negative effects on the performance of model transfer. We thus conclude that (a) Maxent is robust to predictor collinearity in model training; (b) the strategy of excluding highly correlated variables has little impact because Maxent accounts for redundant variables; and (c) collinearity shift and environmental novelty can negatively affect Maxent model transferability. We therefore recommend to quantify and report collinearity shift and environmental novelty to better infer model accuracy when models are spatially and/or temporally transferred. Excluding highly correlated variables does not affect Maxent model performance. Model transfer may lead to novel environment and collinearity shift, while both can negatively affect model performance.

Understanding the spatial patterns of species distribution and predicting suitable habitats for threatened species are central themes in land use management and planning. In this study, we examined the geographic distribution of threatened mire plant species and identified their national hotspots, i.e. areas with high amounts of suitable habitats for threatened mire plant species. We also determined the main environmental correlates related to the distribution patterns of these species. The specific aims were to: (1) identify the environmental variables that control the distribution of threatened peatland species in a boreal aapa mire zone, Finland; and (2) to identify the richness patterns and hotspots of threatened species. Our results showed that the combination of individual species models offers a useful tool for identifying landscape-scale richness patterns for threatened plant species. The modeling performance was high across the modelled species, and the richness patterns generated by single models coincide with the expected richness pattern based on expert knowledge. The method is therefore a powerful tool for basic biodiversity applications. In cases where reliable models for species occurrences and hotspots can be produced, these models can play a significant role in land-use planning and help managers to meet different conservation challenges.

An upsurge in anthropogenic impacts has hastened the decline of the red panda (Ailurus fulgens). The red panda is a global conservation icon, but holistic conservation management has been hampered by research being restricted to certain locations and population clusters. Building a comprehensive potential habitat map for the red panda is imperative to advance the conservation effort and ensure coordinated management across international boundaries. Here, we use occurrence records of both subspecies of red pandas from across their entire range to build a habitat model using the maximum entropy algorithm (MaxEnt 3.3.3k) and the least correlated bioclimatic variables. We found that the subspecies have separate climatic spaces dominated by temperature‐associated variables in the eastern geographic distribution limit and precipitation‐associated variables in the western distribution limit. Annual precipitation (BIO12) and maximum temperature in the warmest months (BIO5) were major predictors of habitat suitability for A. f. fulgens and A. f. styani, respectively. Our model predicted 134,975 km² of red panda habitat based on 10 percentile thresholds in China (62% of total predicted habitat), Nepal (15%), Myanmar (9%), Bhutan (9%), and India (5%). Existing protected areas (PAs) encompass 28% of red panda habitat, meaning the PA network is currently insufficient and alternative conservation mechanisms are needed to protect the habitat. Bhutan's PAs provide good coverage for the red panda habitat. Furthermore, large areas of habitat were predicted in cross‐broader areas, and transboundary conservation will be necessary.

The main purpose of the work was to test the applicability of bioclimatic modeling methods to mosses. Due to tiny size bryophyta are confined to micro-habitats, which can transmute the influence of climatic factors. Crossidium squamiferum was taken as test object. Potentially suitable climatic area of the species in the world was simulated using maximum entropy (MaxEnt) modeling on base of four datasets different in volume (from 24 to 267 points). All the models are characterized by valid AUC values (from AUC=0.72 to AUC=0.96). According to the calculations, the most important variables determining the distribution of C. squamiferum are BIO4 (Temperature seasonality) and BIO8 (mean temperature of the wettest quarter). Habitats of the species in southern Siberia mark the Northern climatic boundary of the species area in Eurasia.

Using 35 presence-only data samples and five uncorrelated bioclimatic variables, we made species distribution models (SDMs) for 4 species of critically endangered (CR) liverworts from genus Jungermanniales and Marchantiales (Cephaloziella elegans, Leiocolea heterocolpos, Lophozia wenzelii and Riccia papillosa) using the maximum entropy modelling method (MaxEnt). Since we were modelling CR species, only one model proved to be strong enough to be used in the field. However, SDMs can serve as effective and fast tools for acceleration of the discovery of the rare and endangered species. The final model presented in this study can serve as a guide to future survey expeditions, the conservation of the target species and also to help understand their ecology.
Book
This handbook provides keys, descriptions and illustrations for the 850 species of liverworts and hornworts recorded from Colombia and Ecuador (148 genera, 47 families). The largest genera are Lejeunea (66 spp.), Plagiochila (65), Frullania (54), Radula (33), Metzgeria (33), Cololejeunea (32), Cheilolejeunea (30), Bazzania (26), Drepanolejeunea (25), Ceratolejeunea (18), Diplasiolejeunea (18), and Syzygiella (18). Species descriptions include discussion of characters necessary for identification and taxonomic relationships, worldwide distribution as well as distribution and habitat in Colombia and Ecuador. Descriptions and keys to genera, families, orders and classes are also provided, and their recognition and relationships are briefly discussed. The introduction of the book includes chapters on the history of floristic exploration, diversity, endemism and classification. A glossary, bibliography and index to scientific names are also provided. Since Colombia and Ecuador harbour a large part of the neotropical bryophyte flora, the book may be useful as an identification manual for many parts of tropical America.

Bryophytes include about 20,000 species characterized by their poikilohydric condition, high long-distance dispersal capacities, and cold tolerance. Despite these specific life-history traits, large-scale biogeographic patterns in bryophytes are consistent with those observed in other groups, wherein they have been interpreted in terms of historical factors. Comparative phylogeographic analyses in bryophytes and angiosperms suggest, however, that spatially congruent patterns may not necessarily arise from common processes. This is best illustrated by the strikingly lower rates of endemism at all taxonomic and spatial scales in bryophytes due to their failure to diversify in-situ and the rapidity at which they enlarge their distribution range. In particular, the striking transoceanic disjunctions that are typical for many bryophyte species and their low community turnover at broad geographic scales both point to the higher capacities of bryophytes for long-distance dispersal than angiosperms. Such high long-distance dispersal capacities are reflected in the lower spatial genetic structure of bryophytes as compared to angiosperms at large geographic scales. This explains why, as opposed to the expectations of MacArthur & Wilson's model, bryophyte species richness is not necessarily lower on islands than on continents, suggesting that community assembly is more constrained by ecological filtering than dispersal limitations in bryophytes. The low relevance of historical factors for global patterns of bryophyte species richness has contributed to the idea that, as opposed to the predictions of one of the most general rules in ecology, bryophyte species richness does not decrease with latitude due to a strong tropical niche conservatism. Recent evidence for the existence of a latitudinal species richness gradient in bryophytes raises, however, the question of why bryophytes diversified faster in the tropics. This and other avenues of research in bryophyte biogeography are discussed.
