Natural systems face human pressures, demanding urgently Ecological Integrity (EI) assessments. EI assessments identify the state of an ecosystem through biotic and abiotic indicators. Fauna is a key element in the functioning of ecosystems, and ther

The juxtaposition of climatic zones in tropical mountains is considered one of the leading causes of the high diversity of tropical mountains; high peaks block oceanic winds, causing mid-elevation peaks of precipitation and diversity. Also, historica

In biological control, joint releases of predators and parasitoids are standard. However, intraguild predation (IGP) can occur when a predator attacks a parasitoid, potentially affecting pest control dynamics. In addition to the focal prey (FP), Tria

Empirical evidence has shown that introduced honeybees, Apis mellifera L., can change the structural organization of ecological networks involving pollinators and flowering plants. In this case, studies have shown that A. mellifera is highly connecte

Top-down control by large herbivores is a well-known driver of plant diversity structure and productivity. Yet, for forest ecosystems the sign and magnitude of herbivore control across resource gradients is not well understood. We conducted a series

Studies at local spatial scales have shown that the generalist honeybee Apis mellifera L. can strongly affect the structural organization and properties of pollination networks. However, there is still little knowledge on how the connectivity of the

The impact of storms on coastal dunes and beaches and the effects they induce in topography and plant communities are natural processes that contribute to maintaining natural coastal dynamics. However, because coasts are often densely populated, thes

There are different methodologies used to make an inventory of social wasps. In general, these methods are divided into active search and passive collections. Each method has a different performance, depending on the environment in which the collecti

Background: Although pollen morphology has always been an important tool in plant systematics, the possibility of distinguishing between related taxa is still debated. A difficult case is the cycads, where their morphology and small size is very simi

Social wasps participate in food webs, act as biological control agents in small crops and the natural environment, and act as potential pollinators. The objective of this study was to carry out an inventory of social wasps in five phytophysiognomies
