Under‐ice photoautotrophs in lakes are generally considered to be limited by light rather than nutrients. Despite reduced light intensity under the ice, there is increasing evidence that suggests some lakes support high levels of photoautotrophs. We explored how snow cover (i.e., light) and nutrients (i.e., nitrogen and phosphorus) influence ice‐associated photoautotroph growth in a Minnesota, USA lake. Using a novel under‐ice...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
Drought reduces floral resources for pollinatorsNARA Subscribed
Climate change is predicted to result in increased occurrence and intensity of drought in many regions worldwide. By increasing plant physiological stress, drought is likely to affect the floral resources (flowers, nectar and pollen) that are available to pollinators. However, little is known about impacts of drought at the community level, nor whether plant community functional composition influences these impacts. To address...
Evaluating the drivers of Indo‐Pacific biodiversity: speciation and dispersal of sea snakes (Elapidae: Hydrophiinae)NARA Subscribed
Aim There are several competing hypotheses to explain the high species richness of the Indo‐Australian Archipelago ( IAA ) marine biodiversity hotspot centred within Southeast (SE) Asia. We use phylogenetic methods to provide a novel perspective on this problem using viviparous sea snakes, a group with high species richness in the IAA that is highly distinct from other taxa previously studied, both phylogenetically (Reptilia,...
Conservationists are increasingly engaging with the concept of human well‐being to improve the design and evaluation of their interventions. Since the convening of the influential Sarkozy Commission in 2009, development researchers have been refining conceptualizations and frameworks to understand and measure human well‐being and are starting to converge on a common understanding of how best to do this. In conservation, the te...
Multilocus phylogeography of the sea snake H ydrophis curtus reveals historical vicariance and cryptic lineage diversityNARA Subscribed
The I ndo‐ A ustralian archipelago ( IAA ) supports the world's highest diversity of marine fish, invertebrates and reptiles. Many of the marine fish and invertebrates show congruent phylogeographic patterns, supporting a view that the region's complex geo‐climatic history has played an important role in generating its exceptional biodiversity. Here, we examine population genetic structure of the viviparous sea snake, H ydroph...
Conversion of southern rock lobster ( Jasus edwardsii ) carapace length to tail width for enforcement of size limitsNARA Subscribed
The morphometric relationship of carapace length (CL) to tail width (TW) of southern rock lobster ( Jasus edwardsii ) was determined to assist enforcement of existing minimum size limits and also to enable the development of an upper size limit in Tasmania. Data were collected from southern rock lobsters in the wild and at processors and used to develop a system for measuring TW which reduces measurement error. Linear regressi...
The Hutt River estuary near Wellington New Zealand has a luxuriant intertidal band of green macroalgae growing throughout the year. Investigations of water chemistry suggested that the upstream freshwater river was likely P‐limited and passed on watershed nitrogen nutrients to the estuary. P fertilisation of the estuary from marine waters led to crossing N and P nutrient loadings that support the observed macroalgal proliferat...
