Evolution of resistance within insects to pest control has frequently resulted in changes to the organism’s morphotype, including changes in wing shape. By measuring these changes, it is possible to distinguish resistant from non-resistant populations. Geometric morphometrics (GM) quantifies morphological variation within and among populations, it has been used in previous studies to identify changes in morphotype and distinguish between resistant and non-resistant populations of insects. Helicoverpa Zea (corn earworm) is one of the most economically damaging pests for crops across the Unite...

In Eastern Andalusian Spanish, consonants are deleted in syllable-final position, triggering regular gemination of a following consonant, even across word boundaries. This paper investigates five underlying phonemic contexts involving /t/, including singleton /t/ and four different underlying /C+t/ sequences that typically surface as [t:], by analyzing how durational and formant differences vary depending on the presence and identity of the preceding underlying consonant. Following the acoustic and statistical analyses of 444 instances of /ˈeta/, /ˈesta/, /ˈekta/, /ˈepta/ and /ˈeksta/, a ...
