Environmental Toxicology, EarlyView.ABSTRACT As top predators, terrestrial carnivores face great risk of pesticide exposure and serve as sentinels of environmental contamination. Additionally, terrestrial carnivores are frequently threatened by intentional or secondary poisoning with highly toxic compounds, such as carbamates and organophosphates.

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties
Journal of Animal Ecology, EarlyView.Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...

Aplicação de produtos biológicos estimulantes no desenvolvimento vegetal em hortaliças
, 2022 The use of stimulating products in the production of vegetables is of great importance for a better establishment of seedlings in the field, a factor directly related to seed germination. The aim of this study was to verify the effects of different biological products stimulating plant development such as Ascophylum nodosum, Ecklonia maxima, Brutal ...

Journal of Animal Ecology, EarlyView.This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Journal of Animal Ecology, EarlyView.We show that ant‐mediated seed dispersal components respond differently to local soil conditions and landscape structure in Caatinga agricultural mosaics. Low‐intensity rainfed croplands maintained or enhanced seed removal compared to natural remnants, highlighting how small‐scale agriculture can sustain key ecological processes in human‐modified dry ...

Foeniculum vulgare Essential Oils: Chemical Composition, Antioxidant and Antimicrobial Activities
Natural Product Communications, 2010 The essential oils from Foeniculum vulgare commercial aerial parts and fruits were isolated by hydrodistillation, with different distillation times (30 min, 1 h, 2 h and 3 h), and analyzed by GC and GC-MS. The antioxidant ability was estimated using four
