Growth Allocation Shifts in the Invasive Hydrilla verticillata Under Interspecific Competition with Native Submerged Macrophytes

Plants
Communities with high native species diversity tend to be less susceptible to the establishment of invasive species, especially in studies that test their local impact.

Changes in Species Richness and Composition of Tiger Moths (Lepidoptera: Erebidae: Arctiinae) among Three Neotropical Ecoregions [PDF]

, 2016
Paraná, Yungas and Chaco Serrano ecoregions are among the most species-richterrestrial habitats at higher latitude. However, the information for tiger moths, one of the most speciose group of moths, is unknown in these ecoregion. In this study, we assess

Variation in population size, nest distribution, colony extent, and timing of movements at the largest known parrot colony

Wildlife Biology, EarlyView.
Psittaciformes are among the most threatened birds, and population size and trend estimates are needed to aid conservation. The burrowing parrot Cyanoliseus patagonus is undergoing substantial changes in its population size, due to habitat degradation, trapping for the pet trade, and persecution as crop pest.

Host species and age‐specific variation on Hepatozoon prevalence and its effect on body condition in two Neotropical crocodiles

Wildlife Biology, EarlyView.
Many populations of species belonging to the order Crocodilia are threatened due to illegal trafficking, indiscriminate hunting, and habitat loss and degradation affecting crocodilian health and parasitic load. Although several studies have revealed that crocodiles, caimans, and alligators are frequently infected by Hepatozoon spp., the results from ...

Increasing dominance of large lianas in Amazonian forests [PDF]

, 2002
Ecological orthodoxy suggests that old-growth forests should be close to dynamic equilibrium, but this view has been challenged by recent findings that neotropical forests are accumulating carbon and biomass, possibly in response to the increasing ...

Assessing the current distribution and potential habitat availability for Kaempfer's tody‐tyrant: a restricted‐range and threatened species from the Atlantic Rainforest

Wildlife Biology, EarlyView.
Human disturbances are threatening biodiversity worldwide, and species with restricted geographic distribution or small population sizes are more likely to become extinct. The prevention of extinctions is an urgent matter and knowledge on the ecology and distribution of threatened species is required to outline conservation strategies.

Wet and dry extremes reduce arthropod biomass independently of leaf phenology in the wet tropics

Global Change Biology, Volume 29, Issue 2, Page 308-323, January 2023., 2023
Although two‐thirds of terrestrial vertebrates consume insects and spiders, how changing rainfall regimes will affect arthropods remains poorly understood. Using spatiotemporal variation in tropical montane climate as a natural experiment, we show arthropod biomass maxima at intermediate rainfall as 3 months of both wet and dry extremes reduced ...
