Odonate species are classified in terms of their thermoregulatory behavior into flier and percher categories. Larger perchers could be more efficient thermoregulators sunny sites smaller depend on air temperature. In this paper, an analysis the behavioral temporal budget odonate neotropical assemblage was performed to determine role body size territorial defense general strategies. This revealed three groups based time budget. The first second contained that remained perched for most...
The cultivation of genetically modified crops in Brazil has led to the need assess impacts this technology on non-target species. Under field conditions, potential effect insect biodiversity was evaluated by comparing a homogeneous corn with conventional and transgenic maize, expressing different Bt proteins seven counties Minas Gerais, Brazil. richness pattern species, secondary pests natural enemies were observed. results do not support hypothesis that protein affects biodiversity....
Residence advantage in heterospecific territorial disputes of Erythrodiplax Brauer species (Odonata, Libellulidae). Territories are the outcome interactions determining where and how long individuals settle. To odonate species, aggressive not so common since can be predetermined by advantages such as residency, age, body size. However, it is possible to predict that at disputes, larger body-sized or more have some profits overcoming these individual advantages, generating patterns hierarchy....
Polythoridae comprise a widespread group of species in the New World tropics, but little is known about their behavior or life history. Here, we described reproductive Amazonian Chalchopteryx rutilans, using mark-recapture techniques. Males were resident and territorial, though found disputes (complex flight manoeuvres) to be rare. Trunks (rotting wood) important male persistence sites, as these are locations preferred by females for oviposition. The mating system C. rutilans may comparable...
Classifications in mate systems of Odonata are generally based the male ability to control female access oviposition resources. In this paper we discuss criteria for territory selection dragonflies Perithemis mooma Kirby and Orthemis discolor (Burmeister) (Libellulidae), Viçosa, Brazil, controlling availability perches aquatic vegetation. P. males defended territories with vegetation thus their choice was probably related resource females. O. preferred sites tall perches, possibly because a...
The present study shows the distribution of alien fish species in tropical lakes middle Doce river basin, southeastern Brazil, obtained from a rapid assessment program. causes for their introductions were sportfishing improvement some specific and aquaculture studied basin. Presently, these have wide occurring 41 54 studied, representing an actual threat to regional native community. natural connection among streams during rainy season dispersal mediated by local people are main invasion...
Abstract: Aim Assessing the damage caused to natural environments and native biodiversity by alien species is challenging. We tested whether number of detections affected total or invader richness, considering importance predicting which are more probable future invaders. Methods summarized a research information survey conducted on amphibians, annelids, aquatic macrophytes, cnidarians, crustaceans, fish, microorganisms, mollusks, nemathelminths, platyhelminths, reptiles, for Brazilian...
<p>Desde o final de 2019, a pandemia COVID-19 tem demandado trabalho cientistas em todo mundo.
