Development of a functional approach in a grassland vegetation sub-model = Desenvolvimento de uma abordagem funcional em um submodelo vegetal campestre

Acta Scientiarum: Animal Sciences, 2008
To improve our understanding of grassland dynamics under different levels of utilization, a functional description of the vegetation was introduced in a deterministic model. The selected traits and their parameterization were based on the results of a longtermexperiment in which temperate grasslands were managed for 12 years with three levels of ...

Conservation priorities for Neotropical water striders (Hemiptera: Heteroptera: Gerridae) under climate change

Conservation Science and Practice, EarlyView.
Hydrologic changes driven by climate change are affecting aquatic biota in the Neotropical Region, with significant impacts on water striders. Species distribution models predict an increase in conservation importance for the northern Andes and coastal areas of eastern South America, while central South America shows a decline. The observed changes are

She Doesn't Whisper: Female‐Prominent Stridulation Shaped by Morphology in a Buthid Scorpion and Insights on Its Function

Ethology, EarlyView.
Sexual dimorphism and stress‐induced stridulatory responses in Jaguajir rochae (Borelli, 1910). Females exhibited greater absolute pectinal size and higher sound pressure levels, whereas males showed higher pectinal allometric ratios relative to body size, lower sound frequencies, and shorter delta times.

Does Survey Angling CPUE Reflect Population Density of Northern Pike (Esox lucius) in Small Boreal Lakes?

Fisheries Management and Ecology, EarlyView.
ABSTRACT Knowing the relationship between catch per unit effort (CPUE) and population density is crucial for the management of recreational fisheries. We conducted standardized angling for pike in 16 lakes (3.4–22.1 ha) to test whether lure type, color, and pike density affect CPUE and the size of captured fish.

Geographical distribution of the Pinnated Bittern (Botaurus pinnatus): Update and seasonal movement pattern

Ibis, EarlyView.
The Pinnated Bittern Botaurus pinnatus (Ardeidae) is a widely distributed Neotropical wading bird whose distribution and seasonal status remain poorly resolved. Discrepancies among published literature, citizen science records and the range currently assumed by BirdLife International indicate that both its geographical distribution and migratory ...

Distribution models of polysphinctine parasitoid wasps (Hymenoptera: Ichneumonidae) reveal sampling bias and flag potentially overlooked host interactions

Insect Conservation and Diversity, EarlyView.
We quantified the geographical overlap between parasitoid wasps and their known host spiders. We could assess which parasitoid species have more limited information about their interactions and are subject to geographical survey bias. We generated sampling bias maps to assist other researchers in identifying where the main sampling gaps are.

Projected Climate‐Suitable Area for Apis mellifera (Apidae) and Its Spatial Overlap With a Mining Tailings Footprint in South‐East Brazil

Journal of Applied Entomology, EarlyView.
ABSTRACT Climate change and environmental disasters can jointly impact species distributions and ecosystem stability, including pollinators and the resources they rely on. We used occurrence and climate data to predict the distribution of Apis mellifera in the Doce River Basin, south‐east Brazil, under baseline and future scenarios (2050).
