High Densities of Large Herbivores Rapidly Disrupt Ecosystem Integrity. [PDF]
Human‐driven increases in large herbivore populations are emerging as a widespread global change pressure on terrestrial ecosystems. Using the largest hectare‐scale herbivore density manipulation experiment conducted to date, we show that high deer densities rapidly disrupt ecosystem integrity across multiple dimensions of biodiversity and ecosystem ...

Microbe-induced resistance involves priming of direct or indirect defenses according to the stage of herbivory. [PDF]
Summary Microbe‐induced resistance (MIR) encompasses a broad range of plant responses that mediate both direct and indirect defenses against herbivores. However, previous studies have addressed MIR in relation to either direct or indirect defenses in isolation, overlooking potential conflicts or synergies that may arise between MIR‐elicited defense ...

Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests. [PDF]
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

Strong scale-dependent relationships between fine-root function and soil properties uncovered with spatially coupled sampling. [PDF]
Summary Substantial fine‐root trait variation is found at fine spatial scales but rarely linked to edaphic variation. We assessed the spatial scales of variation in fine‐root traits and adjacent soils using a spatially coupled, nested sampling scheme along a fertility gradient in a seasonally dry tropical forest tree, Handroanthus ochraceus.

Changes in community composition and functional diversity of European bats under climate change. [PDF]
Abstract Climate change is predicted to drive geographical range shifts that will result in changes in species diversity and functional composition and have potential repercussions for ecosystem functioning. However, the effect of these changes on species composition and functional diversity (FD) remains unclear, especially for mammals, specifically ...

We took advantage of a long‐running field warming experiment, the Tropical Responses to Altered Climate Experiment (TRACE) located in the Luquillo Experimental Forest in Puerto Rico to evaluate the effects of +4°C warming on relative growth rates (RGR) and time to leaf colonization of a recently senesced leaf for drought‐tolerant species Marasmius ...

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

Community‐level effects of Müllerian mimicry on pollinator diversity and functioning
Read the free Plain Language Summary for this article on the Journal blog. Abstract Müllerian mimicry, a mutualistic interaction in which harmful species evolve similar warning signals, is often accompanied by niche divergence among mimetic species. While these aspects have traditionally been studied in an evolutionary context, their community‐level ...

Hummingbirds play an important role as pollinators and are one of the primary examples of animal–plant coevolution. However, factors such as land‐use change, urbanization, exotic species introductions and the disappearance of native plants can negatively affect the persistence of hummingbird populations.
