Effects of maternal age and mass on foraging behaviour and foraging success in the northern elephant seal [PDF]
Functional Ecology, 2013 SummaryAnimals that show indeterminate growth and put relatively constant proportions of stored body reserves towards annual reproductive effort are confronted with a problem of meeting ever‐increasing energetic demands in unpredictable environments.We examined how intrinsic traits, mass and age, as well as extrinsic environmental features impact ...

Bioscience Journal, 2022 The control of sward height at the early stockpiling period influences the structural characteristics of stockpiled sward in winter. So, we conducted this work on the Cerrado region of Brazil based on the hypothesis that the reduction of pasture height ...

Breeding Efficiency for Salt Tolerance in Alfalfa
Life, 2023 Alfalfa (Medicago sativa L.), one of the most extensively grown forage crops, is sensitive to saline soils. We measured the breeding efficiency for increased salt tolerance in alfalfa by comparing lines selected from BC79S, CS, and SII populations with ...

Ontogenetic influences on foraging and mass accumulation by big brown bats (Eptesicus fuscus) [PDF]
Journal of Animal Ecology, 1998 SummaryJuvenile flying animals, including bats, often cease increasing, or even decrease in body mass after the onset of flight. The low body mass of juvenile bats may be a result of stresses associated with the initiation of flight, or may be an adaptation to reduce flight costs.To test these hypotheses, the body masses of adults and unknown aged ...

Forage intake processes by goats on a massai grass pasture with different sward heights
Semina: Ciências Agrárias, 2016 The objective of this study was to evaluate the forage-intake process of goats feeding on Massai grass pastures with different heights (40, 50, 60, and 70 cm). The experimental design was completely randomized, with treatments corresponding to four sward

Oxygen minimum zone: An important oceanographic habitat for deep-diving northern elephant seals, Mirounga angustirostris. [PDF]
, 2017 Little is known about the foraging behavior of top predators in the deep mesopelagic ocean. Elephant seals dive to the deep biota-poor oxygen minimum zone (OMZ) (>800 m depth) despite high diving costs in terms of energy and time, but how they ...
