Larval Size and Recruitment Mechanisms in Fishes: Toward a Conceptual Framework
A large number of mechanisms controlling recruitment in fishes are unknown and the literature on recruitment mechanisms is large and growing rapidly, but it is unclear how these mechanisms are influenced by environmental influences.
Understanding impacts of fisheries bycatch on marine megafauna
A Stage‐Based Population Model for Loggerhead Sea Turtles and Implications for Conservation
Management of many species is currently based on an inadequate under- standing of their population dynamics. Lack of age-specific demographic information, particularly for long-lived iteroparous…
Temperature as an Ecological Resource
It is suggested that viewing temperature and other niche axes in the way ecologists have viewed food resources would be useful, and if animals successfully compete for their thermal niche, growth and perhaps other measures of fitness are maximized.
LIFE HISTORIES AND ELASTICITY PATTERNS: PERTURBATION ANALYSIS FOR SPECIES WITH MINIMAL DEMOGRAPHIC DATA
This work compared the elasticity patterns generated by the life tables of 50 mammal populations and found that mammals that mature early and have large litters also have a large impact on the contribution of juvenile survival to λ.
Quantifying the effects of fisheries on threatened species: the impact of pelagic longlines on loggerhead and leatherback sea turtles
A bycatch assessment for loggerhead and leatherback sea turtles that are incidentally caught by global pelagic longlines is presented and it is suggested that thousands of these turtles die each year from longline gear in the Pacific Ocean alone.
Habitat structural complexity and the interaction between bluegills and their prey
Bluegill sunfish restricted to experimental ponds varying in vegetation density grew better and consumed more prey at intermediate Macrophyte density than fish held at either low or high macrophyte densities, suggesting that feeding rates of predators may be maximized at intermediate structure.
Global patterns of marine turtle bycatch
Fisheries bycatch is a primary driver of population declines in several species of marine megafauna (e.g., elasmobranchs, mammals, seabirds, turtles). Characterizing the global bycatch seascape using…
An index to assess the health and benefits of the global ocean
An index comprising ten diverse public goals for a healthy coupled human–ocean system and calculated the index for every coastal country provides a powerful tool to raise public awareness, direct resource management, improve policy and prioritize scientific research.

Estimating the vertebrate fauna in a 4.5-million-liter mesocosm aquarium tank at the Monterey Bay Aquarium and sequencing the eDNA from its constituent seawater concludes that eDNA has substantial potential to become a core tool for environmental monitoring, but that a variety of challenges remain before reliable quantitative assessments of ecological communities in the field become possible.
