Partial recovery of large seed arrival following ecological restoration in fragmented tropical rainforests

Oikos, EarlyView.
Forest restoration success depends crucially on the reinitiation of ecological processes such as seed arrival that drive natural regeneration. We know little about whether, by increasing and diversifying local seed sources to alleviate seed limitation, and attracting animal frugivores to alleviate dispersal limitation, restoration could shift seed ...

Ecophysiology and vulnerability to warming of Whorl-tail Iguanas (Tropidurinae: Stenocercus) from the Tropical Andes of Ecuador

Frontiers in Amphibian and Reptile Science
IntroductionEnvironmental changes can significantly affect the performance of ectotherms, as nearly all aspects of their life history are intricately linked to temperature conditions in their habitats.

Distribution of fish among Avicennia and Sonneratia microhabitats in a tropical mangrove ecosystem in South China

Ecosphere, 2019
Mangrove structural complexity plays an important role in the way fish using their habitat. However, the effects of structural attributes on fish spatial distribution remain uncertain.

Matching habitat choice could be brightness‐based instead of hue‐based in green‐brown polymorphic grasshoppers

Oikos, EarlyView.
Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

Quantitative synthesis of the effects of drought on community composition and species interactions in terrestrial ecosystems

Oikos, EarlyView.
Droughts, increasingly frequent under human‐driven climate change, are expected to intensify globally. Both pulsed and prolonged droughts can strongly affect organismal survival and population dynamics, potentially altering terrestrial communities and ecosystems.

The use of multibeam sonar mapping techniques to refine population estimates of the endangered white abalone (Haliotis sorenseni) [PDF]

, 2006
Multibeam sonar mapping techniques provide detailed benthic habitat information that can be combined with the data on species-specific habitat preferences to provide highly accurate calculations of populations in a particular area. The amount of suitable

Catchment conversion to agriculture alters freshwater macroinvertebrate community responses to flow disturbance: results from a replicated in‐stream experiment

Oikos, EarlyView.
Anthropogenic stressors often co‐occur in ecosystems, but their combined impacts are rarely assessed using field experiments. Press disturbances particularly can reshape community dynamics, altering their capacity to withstand or recover from acute pulse disturbances by modifying response diversity.

Urban‐driven homogenization of aquatic subsidy size structure cascades to riparian predator communities

Oikos, EarlyView.
The export of emergent aquatic insects is a critical energy subsidy for terrestrial food webs. While urbanization is known to alter stream communities, its effects on the size structure of these insect subsidies and the subsequent consequences for riparian predators remain poorly understood.

Energetic Consequences for a Northern, Range-Edge Lizard Population

, 2018
Lizards at the northern, cool edge of their geographic range in the northern hemisphere should encounter environmental conditions that differ from those living near the core of their range.

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.
