“…Both managers and scientists were in agreement that the greatest discrepancy between the importance and implementation of concepts occurs for outbreeding depression and evolution (Figures 1 and 2). Management agencies were considered to be doing better at integrating genetic diversity and life history strategies into management decisions (Figure 2), and there is certainly increasing guidance in the literature for how managers can take account of these concepts within revegetation (Breed, Stead, Ottewell, Gardner, & Lowe, 2013; Byrne et al., 2011; Sgrò et al., 2011) and threatened species management (Frankham et al., 2011; Weeks et al., 2011), which may be filtering through to managers. However, further work is needed to understand exactly how managers are applying these concepts to determine whether more effective long‐term management outcomes are likely to be achieved.…”

Despite wide acceptance that conservation could benefit from greater attention to principles and processes from evolutionary biology, little attention has been given to quantifying the degree to which relevant evolutionary concepts are being integrated into management practices. There has also been increasing discussion of the potential reasons for a lack of evolutionarily enlightened management, but no attempts to understand the challenges from the perspective of those making management decisions. In this study, we asked conservation managers and scientists for their views on the importance of a range of key evolutionary concepts, the degree to which these concepts are being integrated into management, and what would need to change to support better integration into management practices. We found that while managers recognize the importance of a wide range of evolutionary concepts for conservation outcomes, they acknowledge these concepts are rarely incorporated into management. Managers and scientists were in strong agreement about the range of barriers that need to be overcome, with a lack of knowledge reported as the most important barrier to better integration of evolutionary biology into conservation decision‐making. Although managers tended to be more focused on the need for more training in evolutionary biology, scientists reported greater engagement between managers and evolutionary biologists as most important to achieve the necessary change. Nevertheless, the challenges appear to be multifaceted, and several are outside the control of managers, suggesting solutions will need to be multidimensional.

“…Similarly, by examining sequence and expression variation in candidate genes, Chen et al (2012) showed that variation in bud set in Norway spruce (Picea abies) along a latitudinal gradient had in part resulted from local selection. These types of approaches can prove useful for assessing climate adaptation in species and help identify climate resilient populations (Steane et al 2014), which are likely to be important to improve the adaptive capacity of a species and therefore should be a conservation priority (Breed et al 2012c).…”

Constraints to and conservation implications for climate change adaptation in plants

Contemporary climate change is having widespread impacts on plant populations. Understanding how plants respond to this change is essential to our efforts to conserve them. The key climate responses of plant populations can be categorised into one of three types: migration, in situ adaptation, or extirpation. If populations are to avoid extirpation then migration and/or in situ adaptation is essential. In this review we first articulate the current and future constraints of plant populations, but trees in particular, to the different adaptation strategies (e.g. space availability, rate of change, habitat fragmentation, niche availability). Secondly, we assess the use of the most appropriate methods (e.g. natural environmental gradients, genome and transcriptome scans) for assessing and understanding adaptive responses and the capacity to adapt to future challenges. Thirdly, we discuss the best conservation approaches (e.g. assisted migration, biodiversity corridors, ex situ strategies) to help overcome adaptive constraints in plants. Our synthesis of plant, and particularly tree, responses and constraints to climate change adaptation, combined with the identification of conservation strategies designed to overcome constraints, will help deliver effective management actions to assist adaptation in the face of current and future climate change.

“…Climate changes are an important deal to predicting impact in forests and for selecting suitable tree species to match future climates for afforestation and restoration (WANG et al, 2016). These maps can be also used to conservation purposes in case of rare or endangered species (MCCUNE, 2016), seed collection purposes (BREED et al, 2013) and when finding new populations (WILLIAMS et al, 2009). …”

ABSTRACT:Modeling of the ecological niche of vegetal species is useful for understanding the species-environment relationship, for prediction of responses to climate changes and for correct reforestation programs and establishment of plantation's recommendation. The objective of this work was to establish a model for the distribution of four tree species (Casearia sylvestris, Copaifera langsdorffii, Croton floribundus and Tapirira guianensis), widely used in reforestation projects in the state of Minas Gerais, Brazil. In addition, we analyzed the relationship between environmental characteristics and the occurrence of species and tested the performance of Random Forest and Artificial Neural Networks as modeling methods. These methods were evaluated by their overall accuracy, sensitivity, specificity, Kappa, true skill statistic and the area under the receiver operating curve. The results showed the species Casearia sylvestris, Copaifera langsdorffii and Tapirira guianensis widely occurring in the state of Minas Gerais, including a broad range of environmental variables. Croton floribundus had restricted occurrence in the southern state, showing narrow environmental variation. The resulting algorithms demonstrated greater performance when modeling restricted geographic and environmental species, as well as species occurring with high prevalence in data. The algorithm Random Forest performed better for distribution modeling of all species, although the results varied for each metric and species. The maps generated had acceptable metrics and are supported by and ecological information obtained from other sources, constituting a useful tool to understand the ecology and biogeography of the target species. MODELAGEM DO NICHO ECOLÓGICOS DE ESPÉCIES ARBÓREAS EM UMA ÁREA TROPICAL BRASILEIRARESUMO: A modelagem de nicho ecológico de uma espécie é útil para a compreensão da relação espécie-ambiente, para a previsão do comportamento frente às alterações climáticas e para a indicação correta em reflorestamentos e estabelecimento de plantações. O objetivo foi modelar a distribuição de quatro espécies arbóreas amplamente utilizadas em projetos de reflorestamento no estado de Minas Gerais (Casearia sylvestris, Copaifera langsdorffii, Croton floribundus e Tapirira guianensis). Como complemento, o objetivo foi analisar a relação entre as características ambientais e a ocorrência de espécies e testar o desempenho das técnicas random forest e redes neurais artificiais como métodos de modelagem. Estes métodos foram avaliados pelas métricas de acurácia global, sensibilidade, especificidade, kappa, true skill statistic e área sob a curva. Verificou-se que as espécies Casearia sylvestris, Copaifera langsdorffii e Tapirira guianensis apresentaram ampla área de ocorrência no estado Minas Gerais, cobrindo ampla gama de variáveis ambientais. Já Croton floribundus demonstrou ocorrência restrita do sul do estado, mostrando estreita variação ambiental. Os resultados dos algoritmos demonstraram maior desempenho na modelagem de espécies geograf...
