Site Characteristics and Prey Abundance at Foraging Sites Used by Lesser Scaup (Aythya affinis) Wintering in Florida
SOUTHEASTERN NATURALIST, 8(2), 363–374.
TL;DR:
It is suggested that current habitat conditions within the northern Indian River Lagoon system meet the overwintering requirements of scaup; however, prey densities in the Mosquito Lagoon may have been too low to be profitable for foragingScaup during the period of the authors' study.

Dispersal traits linked to range size through range location, not dispersal ability, in Western Australian angiosperms
GLOBAL ECOLOGY AND BIOGEOGRAPHY, 18(5), 596–606.
Contributors: A. Gove n, M. Fitzpatrick *, J. Majer* & R. Dunn n
author keywords: Angiosperm diversity; biogeography; dispersal; latitude; myrmecochory; Western Australia
TL;DR:
Range size did not vary with dispersal mode (ant versus wind and vertebrate dispersal) or life-form, and instead varied primarily as a function of the biogeographical region in which a species was found, but range placement did vary among dispersal modes.

INSECTES SOCIAUX, 56(2), 149–156.
Contributors: J. Lessard *, R. Dunn n & N. Sanders *
author keywords: Coexistence; Dominance; Temperature; Tradeoff; Formicidae; Coweeta LTER

Contrasting patterns of resource utilization between juvenile estuarine predators: the influence of relative prey size and foraging ability on the ontogeny of piscivory
CANADIAN JOURNAL OF FISHERIES AND AQUATIC SCIENCES, 66(5), 790–801.
TL;DR:
The findings highlight the importance of the availability of appropriately sized forage fishes to the ontogeny of piscivory and provide evidence that predator-prey size relationships and disparate foraging abilities can generate inter- and intra-specific variation in patterns of resource utilization and predator growth.

Contributors: H. Patisaul n , K. Burke n, R. Hinkle n, H. Adewale n & D. Shea n
author keywords: DPN; PPT; Estrogen; Soy isoflavones; Testosterone; Anxiety; Endocrine active compound; Resveratrol; Equol; Plus maze; ER beta; Estrogen receptor beta
MeSH headings : Analysis of Variance; Animals; Anti-Anxiety Agents / administration & dosage; Anxiety / drug therapy; Behavior, Animal / drug effects; Equol; Estrogen Receptor alpha / agonists; Isoflavones / administration & dosage; Male; Nitriles / administration & dosage; Nitriles / blood; Phenols; Phytoestrogens / administration & dosage; Propionates / administration & dosage; Propionates / blood; Pyrazoles / administration & dosage; Rats; Rats, Long-Evans; Rats, Wistar; Resveratrol; Stilbenes / administration & dosage; Testosterone / blood
TL;DR:
It is determined that DPN can be successfully administered either orally or by subcutaneous injection, although plasma DPN levels are significantly lower if given orally, and the efficacy of ERbeta agonists may depend on gonadal status, therefore the therapeutic potential of ER beta selective agonists to treat mood disorders may be limited.

Modeling misidentification errors in capture-recapture studies using photographic identification of evolving marks
ECOLOGY, 90(1), 3–9.
author keywords: capture-recapture; closed-population models; evolving tags; misidentification; natural tags; photographic identification; population size estimate
MeSH headings : Animal Identification Systems; Animals; Computer Simulation; Models, Biological; Photography / methods; Population Density; Research Design; Time Factors
TL;DR:
It is shown that conventional estimators can seriously overestimate population size when errors due to misidentification are ignored, and that, in comparison, the new estimators have better properties except in cases with low capture probabilities or low misIdentification rates.

Climatic drivers of hemispheric asymmetry in global patterns of ant species richness
ECOLOGY LETTERS, 12(4), 324–333.
Contributors: R. Dunn n , D. Agosti, A. Andersen *, X. Arnan *, C. Bruhl *, X. Cerdá *, A. Ellison *, B. Fisher *
author keywords: Biodiversity; climate change; Eocene; Formicidae; latitudinal gradient
MeSH headings : Animals; Ants / genetics; Ants / physiology; Biodiversity; Biological Evolution; Climate
TL;DR:
Examining the latitudinal pattern of species richness across 1003 local ant assemblages finds latitudinal asymmetry, with southern hemisphere sites being more diverse than northern hemisphere sites, and the most parsimonious explanation is that greater climate change since the Eocene in the northern than in the southern hemisphere has led to more extinctions in the north with consequent effects on local ant species richness.

Interactions between bluefish and striped bass: Behavior of bluefish under size- and number-impaired conditions and overlap in resource use
JOURNAL OF EXPERIMENTAL MARINE BIOLOGY AND ECOLOGY, 368(2), 129–137.
author keywords: Bluefish; Striped bass; Competition; Diet overlap; Habitat overlap
TL;DR:
Overall, foraging behavior in mixed-species treatments and field observations suggest no competitive interactions between adult bluefish and sub-adult striped bass, suggesting that striped bass may have a negative influence on bluefish foraging when bluefish are “out-numbered”.
