Abstract:
... Gall-inducing insects are highly specialized in modifying phenotypes in their hosts. Phytochemical manipulations in galling sites induce tissue growth and differentiation and also refurbish defense response in plant against herbivore infestation. Therefore, plant–herbivore interaction coevolves and gives rise to a chemical arms race by employing refined chemical defense and detoxification mechanis ...

Abstract:
... Earlier studies have shown that Stanleya pinnata benefits from selenium hyperaccumulation through ecological benefits and enhanced growth. However, no investigation has assayed the effects of Se hyperaccumulation on plant fitness in the field. This research aimed to analyze how variation in Se accumulation affects S. pinnata fitness, judged from physiological and biochemical performance parameters ...

Abstract:
... The ability to predict future risks is essential for many organisms, including plants. Plants can gather information about potential future herbivory by detecting volatiles that are emitted by herbivore‐attacked neighbors. Several individual volatiles have been identified as active danger cues. Recent work has also shown that plants may integrate multiple volatiles into their defense responses. He ...

Abstract:
... Marine reserves can increase the abundance and size of harvested fish species, but the indirect effects of protection on wider fish assemblages are less well understood. Better understanding how marine reserves indirectly effect reef fish is essential to interpreting changes in non-targeted taxa and informing management expectations as to the long-term effects of marine protection. We investigated ...

Abstract:
... Road edge effects consist of changes in abiotic and biotic conditions resulting from the new artificial boundaries on the vegetation that are created by a road. It is known that edge effects can have variable direct and indirect influences on the biota, can be species-specific and also site-specific. However, edge effects for most plant species and most of their respective reproductive components ...

Abstract:
... Theoretical studies have shown that in protection mutualism, the modification of top‐down control by protectors may be destabilizing. Central to this prediction are the assumptions that (1) protection mutualism increases the abundance of protected partners, (2) this increased abundance generates a lagged effect on partner resources, and (3) spatial dynamics can be ignored. Although a number of stu ...

Abstract:
... Almost one third of global drylands are open forests and savannas, which are typically shaped by frequent natural disturbances such as wildfire and herbivory. Studies on ecosystem functions and services of woody vegetation require robust estimates of aboveground biomass (AGB). However, most methods have been developed for comparatively undisturbed forest ecosystems. As they are not tailored to acc ...

Abstract:
... STATE OF THE ART: Theory predicts that herbivore pressure should be weaker on islands than on the mainland, owing to lower herbivore abundance and diversity because of dispersal constraints and environmental filtering. As a result, plants on islands should invest less in defences against herbivory. Although early empirical studies supported these predictions, recent systematic island–mainland comp ...

Abstract:
... Tropical tree-climbing lianas form paths that benefit foraging of dominant ants which might protect the host tree against herbivores. In contrast, lianas are often associated with negative effects on growth and reproduction of host trees due to light obstruction, structural stress and other negative effects. It is unclear if dominant ants could mitigate the negative effects of lianas on host plant ...

Abstract:

Navigation may rely on ‘habitual routes’ or ‘Euclidean’ maps: following established routes or computing novel paths, respectively. Folivores are presumed to rely on evenly distributed resources and thus have a reduced reliance on navigation. We tested whether the navigation strategy of southern bamboo lemurs, ...

Abstract:

As grasslands are grass dominated, grass fe ...
