Seed trait and rodent species determine seed dispersal and predation: evidences from semi-natural enclosures

iForest - Biogeosciences and Forestry, 2015
Seed traits affect seed dispersal by animals. However, the combined role of seeds and dispersers in determining seed dispersal is not well explored. We attempted to test how seed traits and predators determine seed dispersal and predation interaction in ...

Spatial-scale dependencies in the predation of seeds by rodents [PDF]

, 1995
Summary 1. Previous studies have shown rates of seed predation in deciduous woodland to be high (on average 60%) and extremely variable in space and time. 2.

Seed Predation of Copaifera langsdorffii Desf. (Fabaceae: Caesalpinioideae) by Rhinochenus brevicollis Chevrolat (Coleoptera: Curculionidae) in a Brazilian Cerrado Fragment

Ecología Austral, 2013
Seed predator insects are generally highly specialized herbivores that can be affected by several plant characteristics. In this study, the resource concentration hypothesis and the plant architecture hypothesis were tested by evaluating the attack of ...

Forest fragmentation and selective logging have inconsistent effects on multiple animal-mediated ecosystem processes in a tropical forest [PDF]

, 2011
Forest fragmentation and selective logging are two main drivers of global environmental change and modify biodiversity and environmental conditions in many tropical forests.

Seed ageing, survival, and the improved seed viability equation; forty years on [PDF]

, 2022
Seed Science and Technology published ‘The quantification of ageing and survival in orthodox seeds’ four decades ago. That paper explained the improved seed viability equation, which quantifies seed longevity in response to storage environment, and the ...

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures

Advanced Robotics Research, EarlyView.
This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

Habitat fragmentation alters post‐dispersal more than pre‐dispersal seed predation through edge effects

Ecosphere
In addition to causing loss of biodiversity, habitat fragmentation can alter species interactions. Relative to well‐studied effects of fragmentation on mutualistic interactions like pollination, effects on antagonistic interactions remain poorly ...

Crop size influences pre-dispersal seed predation in the Brazilian Cerrado

Acta Botânica Brasílica, 2017
Many pre-dispersal seed predators are specialized insects that rely on seeds for larval development. These insects may respond to the amount of seeds produced by a plant (i.e.

Agricultural management intensity determines the strength of weed seed predation [PDF]

, 2022
Agricultural intensification both increases disturbances at the field level and reduces habitat heterogeneity at the landscape level and this can have detrimental effects on biodiversity-driven ecosystem services.

Investigations of the Evolved Molecular Basis for Terpenoid Biosynthesis in Marine Sponges

Advanced Science, EarlyView.
Confirming and extending a previous observation in another Bubarida sponge, genomic and functional analyses of A. cavernosa reveal that sponges retain the mevalonate pathway and employ single α‐domain T1TSs and UbiA‐type TSs for terpenoid biosynthesis. The absence of T1TSs clustering with other biosynthetic genes tentatively suggests, based on limited ...
