“…Climatic severity, however, may not be the only factor impacting TDF. In particular, soil fertility has been shown to influence seed germination, morphological adaptations, and physiological responses of plants, with consequences for growth and survival (Murphy & Lugo, ; Singh & Chaturvedi, ). However, the effects of soil fertility on TDF plant communities have shown contrasting results.…”

“…How TDF respond to harsh conditions also depends on species adaptations. As many species inhabiting TDF exhibit a wide array of strategies to overcome stressful conditions, differences among them may blur the overall community response (Singh & Chaturvedi, ). In particular, legumes and deciduous species, are two dominant functional groups with successful adaptations to cope with resource limitation in TDF (Houlton, Wang, Vitousek & Field, ; Santiago, Bonal, De Guzman & Ávila‐Lovera, ; Sprent, ; Vargas, Werden & Powers, ).…”

Climate severity and land‐cover transformation determine plant community attributes in Colombian dry forests

Tropical dry forests (TDF) are known to be resource‐limited due to a marked seasonality in precipitation. However, TDF are also shaped by factors such as solar radiation, wind speed, soil fertility, and land‐cover transformation. Together, these factors may determine different gradients of environmental harshness that are likely to drive changes in plant community attributes. Here, we evaluated the effects of environmental harshness on plant community diversity and structure of Colombian TDF, based on floristic and environmental data from 15 1‐ha permanent plots. We also analyzed these effects on legumes species only (including both deciduous and non‐deciduous species), deciduous species only (including both legumes and non‐legumes species), and on the whole community excluding either legumes or deciduous separately. Drier conditions and higher land‐cover transformation had the strongest negative effects on species diversity, basal area (BA), and canopy height. Soil fertility, on the contrary, did not have a significant effect on any of the evaluated response variables. Interestingly, legumes maintained their diversity and BA along the climatic gradient, while deciduous species were negatively affected by drier conditions and by an increase in secondary vegetation at the landscape level. Our results suggest that although TDF are limited by water availability, land‐cover transformation strongly increases environmental harshness. Yet, both legumes and deciduous species were differentially impacted by climatic and land transformation variables. Thus, to better understand TDF plant community attributes, it is necessary to consider these gradients and to disentangle their effects on different plant functional groups.

Evergreen and deciduous broad‐leaved tree species can coexist across the globe and constitute different broad‐leaved forests along large‐scale geographical and climatic gradients. A better understanding of climatic influence on the distribution of mixed evergreen and deciduous broad‐leaved forest is of fundamental importance when assessing this mixed forest's resilience and predicting potential dynamics of broad‐leaved forests under future climate change. Here, we quantified the horizontal distribution of this mixed forest in mountains in relation to climate seasonality by compiling vegetation information from the earlier records and our own field sampling on major subtropical mountains of China. We found that the probability of occurrence of this forest in subtropical mountains was positively associated with the latitude but not the longitude. The occurrence probability of this forest was observed at high‐temperature but not precipitation seasonality mountains. Temperature seasonality was five times more important than precipitation seasonality in explaining the total variation of occurrence of this mixed forest. For its distribution, our results shed light on that temperature seasonality was generally a more powerful predictor than precipitation seasonality for montane mixed forest distribution. Collectively, this study clearly underscores the important role of temperature seasonality, a previously not quantified climatic variable, in the occurrence of this mixed forest along geographical gradients and hence yields useful insight into our understanding of climate–vegetation relationships and climate change vulnerability assessment in a changing climate.

“…Tropical dry forest, one of the most extensive forest types in the tropics (Bullock, Mooney, & Medina, ; Dirzo, Young, Mooney, & Ceballos, ), is currently under strong anthropogenic pressures, and its extent has decreased drastically (Miles et al., ; Sánchez‐Azofeifa et al., ; Singh & Chaturvedi, ; Wright, ). Forest clearing to open agricultural fields and pastures for cattle, one of the most impacting disturbances, has resulted in large biodiversity losses (Janzen, ; Quesada et al., ; Trejo & Dirzo, ).…”

Successional dynamics of the bee community in a tropical dry forest: Insights from taxonomy and functional ecology

et al. 2019

Despite the recent rapid growth of tropical dry forest succession ecology, most studies on this topic have focused on plant community attribute recovery, whereas animal community successional dynamics has been largely overlooked, and the few existing studies have used taxonomic approaches. Here, we analyze the successional changes in the bee community in a Mexican tropical dry forest, by integrating taxonomic (species, genus, and family diversity) and functional (sociability, nesting strategy, and body size) information for bees. Over one year, in a successional chronosequence (2–67 years after abandonment) we collected 469 individual bees, representing five families, 36 genera, and 69 species. Linear modeling showed decreases in taxonomic diversity with succession, more strongly so for species. Bee species turnover along succession ranged from moderate to high, decreasing slightly at intermediate stages. An RLQ analysis (ordination method that allows relating environmental variables with functional attributes) revealed clear relations between bee functional traits and the plant community. RLQ axis 1 was positively related to vegetation structural and diversity variables, and to eusociality, while solitary, parasociality, and ground nesting was negatively associated with it. Early successional fallows attract mostly solitary and parasocial bees; older fallows tend to attract eusocial bees with aerial nesting. The continuous taxonomic turnover observed by us and the functional analysis suggest that the disappearance of old fallows from agricultural landscapes would likely result in significant reductions and even local extinctions of particular bee guilds. Considering the low viability of preserving large mature tropical dry forest tracts, the conservation of older successional stands emerges as a crucial component of landscape management.Abstract in Spanish is available with online material.
