Managing the Threat of Subsidized Predators for a Threatened Shorebird

Animal Conservation, EarlyView.
Subsidized predators—native predators that have become more common due to human activities—challenge the persistence of many at‐risk prey species and require creative solutions beyond lethal predator control. In an 8‐year study, we placed small wire cages over western snowy plover nests that allow passage of plovers, but not their predators, and ...

Aposematic signaling and seasonal variation in dorsal pelage in a venomous mammal

Ecology and Evolution, 2021
In mammals, colouration patterns are often related to concealment, intraspecific communication, including aposematic signals, and physiological adaptations.

Risk-driven behaviour in the African leopard:how is leopard behaviour mediated by lion presence? [PDF]

, 2016
Agricultural expansion is restricting many carnivore species to smaller tracts of land, potentially forcing increased levels of overlap between competitors by constraining spatial partitioning.

A STUDY OF THE DEFENSIVE BEHAVIORS OF FREE-RANGING DEKAY’S BROWNSNAKES, STORERIA DEKAYI (HOLBROOK, 1836) [PDF]

, 2015
The defensive behaviors of free-ranging Dekay’s Brownsnakes, Storeria dekayi, were studied at a site in Erie County, Pennsylvania, USA. Twenty-nine unique sequences of defensive behavior were documented.

Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, EarlyView.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Dynamic colour change predicts movement behaviour in a diadromous fish

Journal of Fish Biology, EarlyView.
Abstract Dynamic changes in colour and pattern facilitate key behavioural functions in animals, particularly camouflage for predator avoidance. However, the benefits of colour change depend on the environmental and behavioural contexts. We tested how colour change interacts with movement behaviour in a freshwater fish by filming individuals in an open ...

Morphology and biomechanics of the nests of the Common Blackbird Turdus merula [PDF]

, 2015
Capsule Common blackbirds select different materials, with varying biomechanical properties, to construct different parts of their nest. Aims This study tested the hypothesis that outer components of a nest have a more structural role and so are ...

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

Bird pollinators, seed storage and cockatoo granivores explain large woody fruits as best seed defense in Hakea [PDF]

, 2016
Nutrient-impoverished soils with severe summer drought and frequent fire typify many Mediterranean-type regions of the world. Such conditions limit seed production and restrict opportunities for seedling recruitment making protection from granivores ...

Male‐territory‐visiting polygamy in the sand‐dwelling goby Fusigobius inframaculatus (Gobiidae) inhabiting reef caves

Journal of Fish Biology, EarlyView.
Abstract We conducted an observational field survey of the innerspotted sandgoby Fusigobius inframaculatus on reefs of Kuchierabu‐jima Island, southern Japan, to investigate its mating system. Individuals of the goby maintained home ranges on sandy bottoms within rocky caves or beneath overhangs that served as shelters. Of 34 identified individuals, 32%
