F
Definition requires input - need to decide a standard format - some species Max. no. 1,2,... to 10, 12 in which case we record the Max. no., but other species fecundity is measured in the millions, so no point recording 1,000,001. +
Note ''in stricto'' this term relates to the physical location in which the gametes meet and fuse (or inseminate). It does not assume that the gametic nuclei subsequently fuse, or that one of the haploid components is lost/deactivated. The split between 'external' and 'internal' fertilization requires specialist input. +
G
Traits term needs rewording +
Definition specific to species of freshwater mussels of the families Unionidae and Margaritiferidae. +
Definition specific to Platyhelminthes +

H
Definition requires specialist input - plus a citable reference +
Hard substratum is divided into immobile hard (e.g. bedrock) and mobile hard (e.g. pebbles) that can be moved by strong wave action +
Definition requires specialist input +
I
Definition requires input. Is the 'instar' stage considered to be a larval stage or an juvenile stage. +
Definition requires specialist input +
J
Definition requires input. The above definition is probably not relevant for most species, except some insects and vertebrates (e.g. birds, reptiles, mammals) that have distinct juvenile stages. +
L
Definition requires input - need to decide on standard format - record the range months or seasons over which settlement occurs. Months (Jan., Feb. .... Dec.) are preferred as provide a higher resolution and are independent of hemisphere. But need to record geographical location.
Record if period is minimum, maximum or average. +
Definition requires input - need to decide standard format. The trait value needs to record duration in days or months. Do we record the time from egg to adult i.e. all larval stages, or the duration of each larval stage where there are more than one? +
This traits uses the 'substratum type' trait value list. +
