To house or oust: Honey bee (Apis mellifera) colonies can evaluate and evict drones of low qualityNARA Subscribed
Across the animal kingdom, males advertise their quality to potential mates. Males of low reproductive quality, such as those that are sick, may be excluded from mating. In eusocial species, there is some evidence that reproductive females gauge the quality of their mates. However, males often spend much more time with non-reproductive females when being raised or when returning from unsuccessful mating flights. Do non-reprodu...
On the distribution and diversity of tissue-specific somatic mutations in honey bee (Apis mellifera) dronesNARA Subscribed
Somatic mutations originate from both exogenous (e.g. UV radiation, chemical agents) and endogenous (e.g., DNA replication, defective DNA repair) sources and can have significant impacts on an animal’s reproductive success. This may be especially true for haploid organisms that are susceptible to any deleterious alleles inherited from their parent and any that arise over their lifetime. Unfortunately, little is known about the...
A grazer's niche edge is associated with increasing diet diversity and poor population performanceNARA Subscribed
The core‐periphery hypothesis predicts niche cores should be associated with greater survivorship, reproductive output and population performance rates than marginal habitats at niche edges. However, there is very little empirical evidence of whether niche centrality influences population trends in animals. Using the Cape mountain zebra ( Equus zebra zebra ) as a model system, we evaluated whether niche centrality is associate...
Contemporary and emerging fisheries in The Bahamas—Conservation and management challenges, achievements and future directionsNARA Subscribed
The harvest of marine resources has long‐standing cultural and economic importance to The Bahamas and other small island developing states. Tourists and residents place a demand on local marine resources, particularly Caribbean spiny lobster , Panulirus argus (Latreille), queen conch, Lobatus gigas (Linnaeus) and Nassau grouper, Epinephelus striatus (Bloch), and many fishery products are also sold on the global market. Illegal...
Effects of different capture techniques on the physiological condition of bonefish Albula vulpes evaluated using field diagnostic toolsNARA Subscribed
A study was conducted on bonefish Albula vulpes in The Bahamas to assess the utility of portable physiological diagnostic tools (i‐STAT analyser with E3+ ion and haematology cartridge, ACCU‐CHEK glucose meter and Lactate Pro lactate meter) for field physiology applications in remote locations. Physiological values derived from portable diagnostic tools were significantly related to values obtained from standard laboratory tech...
