“…For example, the Coleopteran species richness and diversity are higher in more recently disturbed habitats than in preserved ones because after perturbation, novel resources promote the arrival of new species, adding to the taxa from the original habitat that were able to persist after disturbance ( Sánchez-Reyes et al, 2019 ). Hence, although specialist species require host plants that are characteristic of mature successional stages, several taxa can be shared among different early successional stages ( DeWalt, Maliakal & Denslow, 2003 ; Cajaiba et al, 2017 ; Sánchez-Reyes et al, 2019 ; Faccion et al, 2021 ), as we found for the pasture and early successional stages of our study. However, how long will the richness and diversity of these modified environments remain high is still a matter of research, in particular, taking into account the projections of larger anthropic environmental alterations in the near future, and with this an unknown impact on Coleopteran communities ( Sage, 2019 ).…”

Coleopterans are the most diverse animal group on Earth and constitute good indicators of environmental change. However, little information is available about Coleopteran communities’ responses to disturbance and land-use change. Tropical dry forests have undergone especially extensive anthropogenic impacts in the past decades. This has led to mosaic landscapes consisting of areas of primary forest surrounded by pastures, agricultural fields and secondary forests, which negatively impacts many taxonomic groups. However, such impacts have not been assessed for most arthropod groups. In this work, we compared the abundance, richness and diversity of Coleopteran morphospecies in four different successional stages in a tropical dry forest in western Mexico, to answer the question: How do Coleopteran assemblages associate with vegetation change over the course of forest succession? In addition, we assessed the family composition and trophic guilds for the four successional stages. We found 971 Coleopterans belonging to 107 morphospecies distributed in 28 families. Coleopteran abundance and richness were greatest for pastures than for latter successional stages, and the most abundant family was Chrysomelidae, with 29% of the individuals. Herbivores were the most abundant guild, accounting for 57% of the individuals, followed by predators (22%) and saprophages (21%) beetles. Given the high diversity and richness found throughout the successional chronosequence of the studied tropical dry forest, in order to have the maximum number of species associated with tropical dry forests, large tracts of forest should be preserved so that successional dynamics are able to occur naturally.

“…At restoration stage I, the significant stress‐tolerant character (largest contribution of the C score) in strategy of adult P. massoniana implies their adaption to this unfavorable environment (Siefert, 2012 ). Arid microclimate, intense solar radiation, and barren soil forced them to store limited water and nutrients in order to withstand long‐term environmental stress (Faccion et al., 2021 ). Hence, they invest these scarce resources in long‐lived structures, leading to a higher leaf dry matter content (LDMC), and are then associated with conservative resource‐use strategy (Dayrell et al., 2018 ; Wright et al., 2005 ) whereby their growth rate is slowed to maximize the probability of survival in such a poor habitat (Christopher et al., 2014 ; Maynard et al., 2021 ).…”

“…Contrary to our expectations, in the restoration stage I, the largest contribution of S component was also observed in strategy of juveniles and saplings. This unexpected finding may indicate that even individuals at early ontogenetic stages in such harsh conditions prioritize resistance to environmental stress rather than rapid resource acquisition and consumption (Faccion et al., 2021 ; Siefert, 2012 ). As ecological restoration proceeds, the ruderal character of juvenile trees is becoming more conspicuous.…”

Intraspecific variation in plant functional traits and ecological strategies is typically overlooked in most studies despite its pivotal role at the local scales and along short environmental gradients. While CSR theory has been used to classify ecological strategies (competitive C; stress‐tolerant, S; ruderal, R) in different plant species, its ability to explain intraspecific variation in ecological strategies remains uncertain. Here, we sought to investigate intraspecific variation in ecological strategies for Pinus massoniana, a pioneer conifer tree for ecological restoration in Changting County, southeast China. By measuring key leaf traits and canopy height of 252 individuals at different ontogenetic stages from three plots spanning distinctive stages along early ecological restoration and calculating their C, S, and R scores, we constructed an intraspecific CSR system. All individual strategies shifted across three restoration stages, with adults from higher S component to higher C component while juveniles from higher S component to higher R component. Our results suggest that while strategies of all P. massoniana individuals start with tolerance to environmental stress, as restoration proceeds, adult transition towards completion for light, whereas juveniles shift to an acquisitive resource use. The study reveals an intraspecific pattern of strategy variation during forest restoration, contributing to our understanding of how plants adapt to diverse environments.

“…Moreover, It is argued that sclerophylly can act as a physical defense against herbivory, or as a mechanism for nutrient conservation and protection of leaf longevity (FERNANDES, 1994;GONÇALVES-ALVIM et al, 2006;SILVA et al, 2009;. Thus, leaves in xeric habitats are expected to be smaller, thicker and unpalatable to herbivores than leaves in mesic habitats (FERNANDES, 1994;BOEGER;WISNIEWSKI, 2003;FACCION et al, 2021).…”

“…Other defensive traits such as leaf morphology have been little investigated (see EDWARDS et al, 2000;SILVA et al 2021). The size and shape of leaves may change according to sun intensity and nutrient availability (BOEGER;WISNIEWSKI, 2003;FACCION et al, 2021). However, not all variation in leaf structure is a consequence of adaptation to physical environmental factors and may be related to leaf herbivory (NIEMELÄ;TUOMI, 1987;MARQUIS;WHELAN, 1996).…”

INTRODUÇÃOA mandioca (Manihot esculenta Crantz) é considerada um alimento básico, porém importante na dieta de inúmeras famílias, tendo em vista que, suas raízes produzem o amido, considerado fonte de energia, além de fornecer renda, principalmente, nas zonas de agricultura tropical (SONNEWALD et al., 2020).A África, Ásia e América do Sul são os principais produtores de mandioca, Na América do Sul, o Brasil lidera a produção, enquanto que na Ásia é a Tailândia e na África a Nigéria, essa produção é de suma importância para economia desses países, principalmente, na África (Nigéria), onde as raízes atuam como alimento básico e essencial para mais de 180 milhões de Nigerianos (FAOSTAT, 2020;OKWUONU et al., 2021). Da mandioca, tudo pode ser aproveitado, das raízes a fécula é extraída, dando origem a subprodutos como farinha de mandioca e farinha de tapioca. Dessa produção temos a origem da manipueira, um liquido amarelado, que por sua vez, após cocção origina o "tucupi", caldo muito importante para preparo de pratos regionais no Norte do Brasil. Das folhas, após cozimento obtêm-se a maniva, que juntamente com outros ingredientes compõe a "maniçoba" que também é um prato regional, apreciado no estado do Pará. Por fim, temos os resíduos de mandioca, sendo aproveitados na alimentação animal, e alguns achados mostram seu potencial para aplicação na produção de bioplásticos (VERSINO; LÓPEZ; GARCÍA, 2015). A composição química desses produtos podem variar, mas de forma geral, são interessantes fontes de carboidratos, vitaminas, minerais e princípios ativos
