Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

GLOBAL MODELS OF HERBIVORY VARIABILITY: DATA FROM THE HERBVAR PROJECT [PDF]

open access: yes
Herbivory is a major selection pressure on plants, which have evolved many different physical and chemical adaptations to prevent animals from eating their tissues. Mean herbivory patterns have been well studied in ecology.

Role of Leaf Traits in Driving Genotypic Diversity‐Mediated Associational Effects in Silver Birch

open access: yesEcology and Evolution
Trees growing in more diverse stands generally experience less herbivory than those in less diverse ones, potentially due to neighbourhood‐mediated variations in traits which influence leaf palatability.

Effects of experimental warming at the microhabitat scale on oak leaf traits and insect herbivory across a contrasting environmental gradient [PDF]

open access: yes, 2023
10 páginas, 3 figuras, 2 tablasForest microclimatic variation can result in substantial temperature differences at local scales with concomitant impacts on plant defences and herbivory.

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

open access: yesThe Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Rapid systemic responses to herbivory

open access: yesCurrent Opinion in Plant Biology, 2022
Rapid systemic signals travel within the first seconds and minutes after herbivore infestation to mount defense responses in distal tissues. Recent studies have revealed that wound-induced hydraulic pressure changes play an important role in systemic electrical signaling and subsequent calcium and reactive oxygen species waves. These insights raise new

Dynamics of biotic resistance to plant invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

Do invasive clonal plants always benefit from clonal integration? Exploring interactions between biocontrol agents and indigenous herbivores

open access: yesBiological Control
Clonal integration can help plants counter environmental stresses, but its effects on plant responses to herbivory remain unclear. We investigated how clonal integration in the invasive Alternanthera philoxeroides and the native Alternanthera sessilis ...

Herbivory mediates grass-endophyte relationships

open access: yes, 2007
Endophytic fungi are plant symbionts living asymptomatically within plant tissues. Neotyphodium spp., which are asexual vertically transmitted systemic fungal endophytes of cool-season grasses, are predicted to be plant mutualists.

What drives animal responses to high severity fire? The role of functional traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.
