Fig. 3 in The "Southern form" of short-finned pilot whale (Globicephala macrorhynchus) in tropical west Pacific Ocean off Taiwan
Fig. 3. Genealogical relationship reconstructed by the medianjoining algorithms via the mtDNA haplotype data for short-finned pilot whales from: A, Taiwanese and Philippines waters (593-bp sequence); B, Worldwide (345-bp sequence). Each circle represents a haplotype and the number in the circle indicates the sample size (when sample size> 1). The number at the bar between each haplotype indicates the position of variable site (Table 3). Haplotypes, sample size, and origin for worldwide data in B from Oremus et al., 2009. Haplotype N is the haplotype most closelyrelated to those long-finned pilot whales (six mutation steps; see Oremus et al., 2009).
Fig. 2 in The "Southern form" of short-finned pilot whale (Globicephala macrorhynchus) in tropical west Pacific Ocean off Taiwan
Fig. 2. Short-finned pilot whales sighted around Taiwan—offshore and beached on the coasts of Taiwan—showing two external morphological characteristics that define the Southern form (Kasuya et al., 1988). A, the post-fin dorsum was uniformly black in all whales observed, four shown here from group of about 30 whales (O8, Table 1), a lighter coloured saddle patch was not seen; B, a male with flattened forehead ("square-head", arrow) from another group of about 90 whales (O19, Table 1), and indistinct lighter coloured mottling over post-fin dorsum (the saddle patch area) on two other whales; C, carcass of a fresh adult male stranded on the west coast of Taiwan (S7) showing a flattened forehead and the lack of a clear post-fin saddle patch, characteristic of the Southern form.

Data and code from: The functional form of specialized predation affects whether Janzen-Connell effects can prevent competitive exclusion
<p><span>Janzen</span><span>-</span><span>Connell</span><span> Effects (</span><span>JCEs</span><span>), specialized </span><span>predation</span><span> of seeds and seedlings near </span><span>conspecific</span><span> trees, are hypothesized to maintain species richness. While previous studies show </span><span>JCEs</span><span> can maintain high richness relative to neutral communities, recent theoretical work indicates </span><span>JCEs</span><span> may weakly inhibit competitive exclusion when species exhibit inter-specific fitness variation. However, recent models make somewhat restrictive assumptions about the functional form of specialized </span><span>predation</span><span> -- that </span><span>JCEs</span><span> occur at a fixed rate when offspring are within a fixed distance of a </span><span>conspecific</span><span> tree. Using a theoretical model, I show that the functional form of </span><span>JCEs</span><span> largely impacts their ability to maintain coexistence. If </span><span>predation</span><span> pressure increases </span><span>additively</span><span> with adult tree density and decays exponentially with distance, </span><span>JCEs</span><span> maintain considerably higher species richness than predicted by recent models. Loosely </span><span>parameterizing</span><span> the model with data from a Panamanian tree community, I elucidate the conditions under which </span><span>JCEs</span><span> are capable of maintaining high species richness. </span></p>
