Abstract:
... Losses of C and N from the forest floor and top 20-cm of soil were estimated following separate severe wildfires at two Long-Term Soil Productivity sites in the Sierra Nevada of California, USA. Experimental treatments applied 20 years prior to the wildfires included factorial combinations of 1) organic matter (OM) removal following clear-cut harvesting (SO, stem only harvest, WTH, whole-tree harv ...

Abstract:
... Sclerurus is a genus of morphologically uniform, strict understorey, leaf litter specialists. We present the first description of the nest and eggs of Ceará Leaftosser S. cearensis from north-east Brazil and review breeding data for the genus. Based on three nests, the nest of S. cearensis was classified as cavity/with-tunnel/low cup, the type typical of the genus. The nests were excavated in bank ...

Abstract:
... The smallest potoo, Rufous Potoo Nyctibius bracteatus is a little-known and inconspicuous species of the understorey in Amazonian terra firme forests, where it roosts by day. Currently, there are few published observations describing its natural history and reproductive ecology. We present data on nest and egg characteristics, nestling appearance, behaviour and development, and parental care, base ...

Abstract:
... Vertical stratification of animal assemblages has been observed in several arthropod taxa. However, for some groups there is conflicting evidence, such as for the neotropical orchid bees. Here, we used a meta-analysis to evaluate trends in abundance and diversity of euglossine bees across strata. We found no evidence of stratification in terms of diversity, but abundance was higher in the understo ...

Abstract:
... As climates change, species with locally adapted populations may be particularly vulnerable as specialization narrows the range of conditions under which populations can persist. Populations adapted to local climate as well as other site‐specific characteristics like soils present challenges for inferring how changing climates affect fitness, as climatic and nonclimatic variables that constitute l ...

Abstract:
... Lianas (woody vines) are abundant and diverse, particularly in tropical ecosystems. Lianas use trees for structural support to reach the forest canopy, often putting leaves above their host tree. Thus they are major parts of many forest canopies. Yet, relatively little is known about distributions of lianas in tropical forest canopies, because studying those canopies is challenging. This knowledge ...

Abstract:

Thus, the ability to survive multiple years of burial and to respond when released are important to vegetation changes and population dynamics. We experimentally evaluated the effects of delayed removal of tephra (aerially transported volcanic ejecta) in an old-growth forest understory near Moun ...

We developed a new segmentation algorithm that is base ...

Abstract:
... To understand time‐lag dynamics in the response of biodiversity to contemporary environmental changes (e.g. macroclimate warming and atmospheric pollution), we need to consider former anthropogenic forcing factors such as past land uses and management practices that can have both compounding and confounding effects. This is especially true in European temperate forests, where legacies from past hu ...

Although variation in the amount of browsed twigs is sometimes used to assess abundance of large herbivores, the potential confounding effect of resource availability on this relationship has not been investigated yet. To fill the gap, we measured how br ...
