An experimental examination of dispersal decisions made by flight‐capable heteropteran insects in urban stormwater pond conditions

Ecological Entomology, EarlyView.
Salty conditions in urban stormwater ponds can influence dispersal timing in species‐specific ways for actively dispersing aquatic heteropteran insects. Assaying multiple aspects of dispersal propensity, Hesperocorixa obliqua emigrated earlier in stormwater pond conditions while overall probabilities remained unchanged; Notonecta undulata emigration ...

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

Fisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Assessing soil and native high Andean grassland quality under grazing: A case study from the wet Puna of Peru

Grassland Science, EarlyView.
Abstract High Andean grasslands are vulnerable to changes in their nutritional quality and carbon sequestration capacity, especially in grazing systems. This study evaluated soil quality and native grasses by measuring carbon, physicochemical parameters, and the nutritional quality of predominant species in the wet Puna of Junín, Peru.

Expansion of invasive carabids across elevation and habitats on sub‐Antarctic South Georgia

Insect Conservation and Diversity, EarlyView.
Two introduced carabid species have continued to expand their ranges on the sub‐Antarctic island of South Georgia over the past 10–15 years. The species have colonised inland valleys and are present across habitats but are more abundant in those with high vegetation cover. N‐mixture models revealed the optimal sampling method, intensity and habitat for

Hidden partnerships in the dark: Cold‐water coral–fish associations in Fiordland, New Zealand

Journal of Fish Biology, EarlyView.
Abstract The ichthyofauna of the Fiordland ecosystems of southern Aotearoa New Zealand was documented during four remotely operating vehicle (ROV) dives between 100 and 350 m depth. A total of 26 fish species were documented within two fiord basins.
